Multi F and Multi F MAX Indoor Unit Engineering Manual
About LG Electronics, Inc.
LG Electronics, Inc. is a global leader and technology innovator
in consumer electronics, mobile communications, and home
appliances, employing more than 213,000 people in more than 60
countries worldwide. LG Electronics, Inc. comprises five
business units—Home Entertainment, Mobile Communications, Air
Conditioning, Business Solutions, and Home Appliance. LG is one
of the world’s leading producers of flat panel televisions, audio and
video products, mobile handsets, air conditioners, and washing
machines. LG’s commercial air conditioning business unit was estab-
lished in 1968 and has built its lineup of residential and commercial
products to include VRF, Multi F, duct-free split systems, packaged
terminal air conditioners (PTACs), and room air conditioners. In
2011, the air conditioning and energy solutions business unit grew to
include LED lighting and solar products. For more information, visit
www.lg-dfs.com.
Multi-Zone Systems
LG HVAC systems offer a range of solutions that are cost efficient,
quiet and attractive. Multi-zone systems are “split” into indoor and
outdoor units, and provide a smart alternative to both central HVAC
and window-mounted air conditioners. These inverter heat pump
systems are available in a variety of configurations to suit differ-
ent cooling and heating situations. Installation by a qualified HVAC
contractor is safe and easy – little to no duct work or sheet metal is
required.
Multi F Systems
LG’s inverter heat pumps can support two, three, or four indoor
units that are typically installed in separate rooms. Each indoor unit
includes its own remote control, allowing the customer to set the
temperature individually. Indoor units are available in several differ-
ent congurations: Art Cool™ Mirror wall-mounted, Art Cool Gallery
wall-mounted, standard wall-mounted, four-way ceiling cassettes,
ceiling-concealed duct (high and low static), and vertical-horizontal air
handling models. Multi F MAX systems, released in 2012, can oper-
ate up to eight indoor units through two-, three-, or four-port branch
distribution units.
Adaptable and Flexible
Multi F outdoor units can be adapted to a wide range of building ap-
plications and sizes such as schools, hotels, hospitals, ofces, and
residences. The system components are lightweight and compact so
they can be placed in buildings without expensive cranes, they easily
fit into most service elevators, and they can be set in place with
minimal structural reinforcements requirements.
Multi F technology allows you to pipe farther by reaching areas of the
building that would require the installation of a second system when
using traditional direct-expansion cooling and heating equipment. Multi
F provides the designer with uncompromised pipe system engineering
exibility—long pipe runs and large elevation differences. Whether your
building is a condominium, a hotel, a school, or an ofce complex, Multi
F is best suited to reach the farthest corners and elevations.
Smaller Chases and Plenums
LG Multi F systems use refrigerant piping to move heat, resulting in
smaller space requirements for piping as compared to chilled water
or roof top systems. This helps reduce the overall construction and
material cost of the building, and gives back leasable space. Flexible
and logical placement of system components, reduced back-and-
forth pipe lengths, and fewer joints lowers installation costs and
minimizes potential leaking.
Quality Commitment
LG is committed to the success
of DFS projects. We provide
technical support during instal-
lation and commissioning. LG
offers a variety of classes
designed for installers and on
Multi F installation. Classes
are conducted at LG’s training
centers and in field locations
at various times throughout the
year and upon special request.
Benefits of Multi F Systems
• Individual zone control
• Long refrigerant piping lengths
• High refrigerant piping elevation differences
• Maximum flexibility
• Operating ranges of 14°F to 118°F (DB) in cooling and -4°F to
64°F (WB) in heating
• Quiet and comfortable environment
• Reduced ductwork

Mechanical Specications
MULTI F SYSTEMS
Multi F Heat Pump Condensing Units
General
A Multi F multi-zone system is comprised of one heat pump outdoor
unit connected to two, three, or four indoor units using a shared
refrigerant piping circuit between the outdoor unit and each indoor
unit, and includes integrated controls supplied by LG. The outdoor
unit is internally assembled, wired, and piped from the factory; all LG
components are manufactured in a facility registered to ISO 9001 and
ISO 14001, set by the International Organization for Standardization
(ISO). The LG Multi F multi zone heat pump system components
comply with Underwriters Laboratories (UL) 1995 Heating and Cool-
ing Equipment Standard for Safety, and bear the Electrical Testing
Laboratories (ETL) mark. The units are certied to AHRI 210 / 240.
Temperature Ranges
The heat pump outdoor units are capable of operating in cooling
mode from 14°F to +118°F ambient dry bulb (installing an optional
Low Ambient Wind Baffle Kit will allow operation down to -4°F in
cooling mode for all Multi F systems). The heat pump outdoor units
are capable of operating in heating mode from -4°F to +64°F ambi-
ent wet bulb without additional low ambient controls.
Frame
The Multi F condensing unit case is constructed from pre-coated
metal that has been tested in accordance with ASTM B-117 salt
spray procedure for a minimum of 1,000 hours. Case has a remov-
able front panel to allow access to major components and control
devices, and legs to secure the unit during installation.
Refrigerant System
Multi F systems have a shared refrigerant circuit field piped to
multiple (ducted, non-ducted or mixed) indoor units to effectively and
efficiently control the heating or cooling operation of the multi zone
system. All refrigerant lines from the outdoor unit to the indoor units
are field-installed and must be insulated separately.
All Multi F systems use R410A refrigerant. The outdoor units are
equipped with a refrigerant strainer, check valves, oil separator,
accumulator, four-way reversing valve, electronic expansion valve(s)
(EEV), high side and low side refrigerant charging ports, and a
service port. Each outdoor unit also includes sensors for suction
temperature, discharge temperature, high-pressure, low-pressure,
heat exchanger temperature, and outdoor temperature conditions.
Refrigeration Oil Control
The outdoor units have an oil separator to separate oil mixed with
the refrigerant gas during compression and return oil to the com-
pressor. The outdoor units also have an oil injection mechanism to
ensure a consistent film of oil on all moving compressor parts at low
speed.
Compressor
Multi F condensing units are equipped with one hermetically sealed,
digitally controlled, inverter driven twin-rotary compressor that
includes Teflon™ coated bearings. The inverter motor is capable
of providing a modulation range of 20Hz to 100Hz with control in
1Hz increments. The compressor is protected with phase-reversal
protection, uses a factory-charge of Polyvinyl Ether (PVE) oil, and is
mounted to avoid the transmission of vibration.
Fan and Motors
Each outdoor unit includes one direct drive variable speed propeller
fan with Brushless Digitally Controlled (BLDC) motor with a horizon-
tal air discharge. Fan blades are statically and dynamically balanced
propeller fans made of durable Acrylonitrile Butadiene Styrene (ABS)
plastic, and include a raised fan guard to limit contact with moving
parts. The motors have inherent overload protection, permanently
lubricated bearings, and a maximum speed up to 950 rpm. All Multi F
outdoor units have a horizontal discharge airflow.
Outdoor Unit Coil
The outdoor unit coils are factory-built of aluminum fins mechani-
cally bonded on copper tubing. Coils have a minimum of two rows, a
minimum of 14 fins per inch, and have been factory pressure-tested.
Coil fins also have a factory applied corrosion-resistant GoldFin™
material with hydrophilic coating that has been tested in accordance
with ASTM B-117 salt spray test procedure for a minimum of 1,000
hours.
Electrical
All Multi F outdoor units shall have 208/230V, 1 phase, 60Hz electri-
cal power capable of operating within ±10% of the rated voltage.
Controls
Factory installed microprocessor controls in the outdoor unit and
indoor units shall perform functions to efficiently operate the multi-
zone system. System wiring must be installed in a tree configura-
tion from outdoor unit to indoor units through four conductor power/
transmission cable. The system is capable of performing continuous
operation, even when power is turned off to an individual indoor unit.

Table 101: LMU36CHV Cooling Capacity Table — Non-Ducted Indoor Units (continued).
TC = Total Capacity (kBtu/h).
PI = Power Input (kW).
Nominal capacity as rated: 0 ft. above sea level with 25 ft. of refrigerant piping.
0 ft. level difference between outdoor and indoor units.
Nominal cooling capacity rating obtained with air entering the indoor unit at 80ºF dry bulb (DB) and
67ºF wet bulb (WB), and outdoor ambient conditions of 95ºF dry bulb (DB) and 75ºF wet bulb (WB).
The shaded table rows indicate reference data. When operating at this temperature, these values can
be different if the system is not running consistently.

Voltage tolerance is ±10%.
Maximum allowable voltage unbalance is 2%.
RLA = Rated Load Amps.
MCA = Minimum Circuit Ampacity.
Maximum Overcurrent Protection (MOP) is calculated as follows:
(Largest motor FLA x 2.25) + (Sum of other motor FLA) rounded
down to the nearest standard fuse size.
Indoor Fan Motor (FLA) is based on the maximum combination of
indoor units.
The max combination for each outdoor unit is:
- 18,000 ODU (LMU18CHV): 12,000 IDU x 2
- 24,000 ODU (LMU24CHV): 12,000 IDU x 2 + 9,000 IDU x 1
- 36,000 ODU (LMU36CHV): 12,000 IDU x 4

• Measurement taken 4.9′ above finished floor, and at a distance of
3.3′ from face of unit.
• Measurements taken with no attenuation and units operating at full
load normal operating condition.
• Sound level will vary depending on a range of factors such as
construction (acoustic absorption coefficient) of particular area in
which the equipment is installed.
• Sound level may be increased in static pressure mode or if air
guide is used.
• Sound pressure levels are measured in dB(A)±3.
• Tested in anechoic chamber per ISO Standard 3745.

Multi F MAX Heat Pump Condensing
Units
General
A Multi F MAX multi-zone system is comprised of one heat pump
outdoor unit connected up to eight indoor units through a branch
distribution unit (BD) using a single refrigerant piping circuit, and
includes integrated controls supplied by LG. Factory-designed and
supplied Y-branches may be used as well.
The outdoor unit is internally assembled, wired, and piped from the
factory; all LG components are manufactured in a facility registered
to ISO 9001 and ISO 14001, set by the International Organization for
Standardization (ISO). The LG Multi F MAX multi-zone heat pump
system components comply with Underwriters Laboratories (UL)
1995 Heating and Cooling Equipment Standard for Safety, and bear
the Electrical Testing Laboratories (ETL) mark. The units are certi-
fied to AHRI 210 / 240.
Temperature Ranges
The heat pump outdoor units are capable of operating in cooling
mode from 14°F to 118°F ambient dry bulb (installing an optional
Low Ambient Wind Baffle Kit will allow operation down to -4°F in
cooling mode for all Multi F systems). The heat pump outdoor units
are capable of operating in heating mode from -4°F to +64°F ambi-
ent wet bulb without additional low ambient controls.
Frame
Multi F MAX condensing unit case is constructed from pre-coated
metal that has been tested in accordance with ASTM B-117 salt
spray procedure for a minimum of 1,000 hours. Case has a remov-
able front panel to allow access to major components and control
devices, and legs to secure the unit during installation.
Refrigerant System
Multi F MAX systems have a single refrigerant circuit field piped with
a manufacturer-supplied BD unit(s) and Y-branches (if applicable) to
multiple (ducted, non-ducted or mixed) indoor units to effectively and
efficiently control the heating or cooling operation of the multi zone
system. All refrigerant lines from the outdoor unit to the BD unit(s)
and from the BD unit(s) to indoor units are field-installed and must
be insulated separately.
Multi F MAX systems use R410A refrigerant. The outdoor units are
equipped with a refrigerant strainer, check valves, oil separator,
accumulator, four-way reversing valve, electronic expansion valve(s)
(EEV), high side and low side refrigerant charging ports, and a
service port. The outdoor unit also includes sensors for suction tem-
perature, discharge temperature, high-pressure, low-pressure, heat
exchanger temperature, and outdoor temperature conditions.
Refrigeration Oil Control
The outdoor unit has an oil separator to separate oil mixed with the
refrigerant gas during compression and return oil to the compressor.
The outdoor unit also has an oil injection mechanism to ensure a
consistent film of oil on all moving compressor parts at low speed.
Compressor
Multi F condensing units are equipped with one hermetically sealed,
digitally controlled, inverter driven twin-rotary compressor that
includes Teflon™ coated bearings. The inverter motor is capable
of providing a modulation range of 20Hz to 100Hz with control in
1Hz increments. The compressor is protected with phase-reversal
protection, uses a factory-charge of Polyvinyl Ether (PVE) oil, and is
mounted to avoid the transmission of vibration. Compressor in the
Multi F MAX outdoor unit is equipped with a hot gas bypass valve.
Fan and Motors
The Multi F MAX outdoor unit includes two direct drive variable
speed propeller fans with Brushless Digitally Controlled (BLDC)
motor with a horizontal air discharge.
Fan blades are statically and dynamically balanced propeller fans
made of durable Acrylonitrile Butadiene Styrene (ABS) plastic, and
include a raised fan guard to limit contact with moving parts. The
motors have inherent overload protection, permanently lubricated
bearings, and a maximum speed up to 950 rpm. Multi F MAX out-
door unit has a horizontal discharge airflow.
Outdoor Unit Coil
The outdoor unit coils are factory-built of aluminum ns mechanically
bonded on copper tubing. Coils have a minimum of two rows, a mini-
mum of 14 ns per inch, and have been factory pressure-tested.
Coil ns also have a factory applied corrosion-resistant GoldFin™ ma-
terial with hydrophilic coating that has been tested in accordance with
ASTM B-117 salt spray test procedure for a minimum of 1,000 hours.
Electrical
Multi F MAX outdoor unit shall be 208/230V, 1 phase, 60Hz electrical
power capable of operating within ±10% of the rated voltage.
Controls
Factory installed microprocessor controls in the outdoor unit, BD
unit(s), and indoor units shall perform functions to efficiently operate
the multi zone system. System wiring must be installed in a tree
configuration from outdoor unit to BD unit(s) to indoor units through
four conductor power/transmission cable. The system is capable of
performing continuous operation, even when power is turned off to
an individual indoor unit.

Mechanical Specications
Branch Distribution Unit
General
Branch distribution units are designed for use with LG Multi F MAX (LMU540HV)
outdoor units, and are internally piped, wired, assembled and run-tested at the
factory. The branch distribution unit is used as an intermediate refrigerant control
device between the outdoor unit and the indoor units to effectively and efficiently
control the heating or cooling operation of the system through the use of electronic
expansion valves.
Refrigerant System
System is designed for use with R410A refrigerant. All refrigerant lines from the
outdoor unit to the branch distribution unit, and from the branch distribution unit to
the indoor units, must be field insulated. The units may be connected to optional
field-supplied and field-installed isolation valves for servicing without evacuating
the entire system.
Piping Capabilities
Maximum piping length from the branch distribution unit to the indoor unit is 49.2
equivalent feet. Maximum elevation difference between branch distribution unit and
indoor unit is 32.8 feet. Maximum elevation difference between two parallel branch
distribution units is 49.2 feet.
Electrical
Each branch distribution unit is designed to operate using 208–230/60/1 power
with voltage variances of ±10%.
Casing
The casing is designed to mount fully concealed above a finished ceiling, is manufactured of galvanized steel plate, and is internally
insulated. Branch distribution units do not require a condensate drain.
Port Assembly
Branch distribution units have a two-pipe system consisting of one vapor pipe and one liquid pipe. Units are available in a choice of two
(PMBD3620), three (PMBD3630) or four ports (PMBD3640 and PMBD3641); branch distribution units include two, two-positioned solenoid
valves per port. Each port for PMBD3620, PMBD3630, and PMBD3640 units connect to one indoor unit for a maximum nominal capacity of
24,000 Btu/h. For PMBD3641 units, ports A, B, C each connect to one indoor unit for a maximum nominal capacity of 24,000 Btu/h; port D
connect to one indoor unit for a nominal capacity of 36,000 Btu/h. Maximum nominal capacity per branch distribution unit is 73,000 Btu/h.
Two branch distribution units can be piped in parallel using accessory Y-branch kit PMBL5620.
Controls
The unit is provided with factory-installed control boards and an integral microprocessor to communicate with the main control board in the
outdoor unit. Communication between the branch distribution unit, the outdoor unit, and the indoor units is accomplished through a 18 AWG,
four-core, stranded and shielded power / communication cable.

Branch Distribution Unit Orientation
Multi F MAX Branch Distribution (BD) Units can be installed in a multitude of
options to fit various building configurations and job or application requirements.
Multi F MAX BD Units include electronic expansion valves that properly seat only if
the BD Unit is installed in an acceptable orientation. Installations with improper BD
Unit orientation risk incomplete valve seating and system performance degradation
from potential refrigerant leakage through the electronic expansion valve.

APPLICATION
GUIDELINES
EQUIPMENT SELECTION PROCEDURE
To choose the multi-zone system that is the most appropriate for the space, as with traditional air-conditioning systems, follow similar
protocols outlined in Manual J from the Air Conditioning Contractors of America (ACCA; see www.acca.org).
1. Obtain the design conditions, and calculate the maximum cool and heat loads for the structure.
2. Select the equipment (choosing the appropriate indoor units and outdoor unit):
• Determine number of zones.
• Determine total number of indoor units (refer to zone load calculations when choosing indoor units).
• Determine number of indoor units allocated to each outdoor unit, considering allowable indoor unit connections, both indoor unit and
outdoor unit capacities, and system piping capabilities.
3. Determine the corrected capacity for the indoor units and outdoor unit using LATS Multi F software (preferred method) or:
• System Combination Tables.
• Capacity Tables (it may be necessary to interpolate).
• Capacity Coefficient Factors (such as refrigerant line length derates, design condition derates, defrost operation derate [heating mode],
altitude derate [if applicable]).
4. Compare corrected capacities to load calculations.
5. Reselect equipment if necessary.
Obtain Design Conditions, Calculate Maximum Cool / Heat Loads
Obtain the winter outdoor/indoor temperature and summer and winter outdoor / indoor temperature design parameters for the location in
which the system is installed. Determine if summer or winter design gains, relative humidity, and building features like skylights, orientation,
number of occupants, etc., would change the total heat loss / gain and sensible / latent heat gain, and then calculate the maximum cool and
heat loads for the space (using Manual J or energy modeling programs).
Select the Equipment
Determine the Number of Zones
Multi F heat pump systems can cool or heat, but not simultaneously. When designing larger-capacity Multi F heat pump systems or a Multi
F MAX system, the designer may be able to combine spaces with similar load profiles located near or adjacent to each other into “thermal
zones.” After combining like spaces into zones that will be served by a single (or grouped) indoor unit(s), calculate the peak cooling and
heating loads for each zone.
Choosing the Appropriate Indoor Units
Determine the appropriate indoor unit capacity that satisfies the given zone load calculations, choose how many (and which styles of) indoor
units will be required. See Table 96 for allowable indoor unit to outdoor unit connections, and the maximum number of connectable indoor
units on each Multi F and Multi F MAX outdoor unit. When choosing, also consider the cooling and heating CFM, featured airflow specifica-
tions, and static pressure (if applicable) for each indoor unit.
Avoid oversizing indoor units in an attempt to increase the air exchange rate in the space. Multi F and Multi F MAX systems are designed for
minimum airflow over the coil to maximize latent capacity while cooling, maintain a comfortable, consistent discharge air temperature while
heating, and minimize fan motor power consumption. In extreme cases, oversizing the indoor units may affect outdoor unit size selection and
compromise the outdoor unit’s ability to effectively match the space load(s).
For proper system operation:
1. At least two indoor units must be connected to the outdoor unit.
2. Total connected indoor unit nominal capacity should be a minimum 40% and a maximum of 133% of outdoor unit nominal capacity.
3. To calculate the connected total indoor unit nominal capacity, simply sum up the nominal capacities of all indoor units.
• For 24,000 and 36,000 Btu/h high static duct and vertical-horizontal air handling indoor units, a 1.3 multiplier must first be applied before
adding to the sum of other smaller indoor units.
• When two 24,000 Btu/h or one 24,000 Btu/h and one 36,000 Btu/h high static duct and / or vertical-horizontal air handling indoor units
are the only connected indoor units, the multiplier is 1.2.

Table 318: Allowable Indoor Unit to Outdoor Unit Connections.
Choosing the Appropriate Outdoor Unit
After all indoor units are properly sized to offset the applicable loads in each zone, select the outdoor unit by choosing a size that meets
both the load-cooling requirement, and offsets the sum of the heating load. Then, the system’s combination ratio should be evaluated and
confirmed it is within the allowable range (the combination ratio compares the nominal capacity of all connected indoor units to the nominal
capacity of the outdoor unit serving them). The total nominal capacity of all indoor units should be smaller than the total nominal capacity of
the outdoor unit. If the combination ratio is more than 100%, the designer is undersizing the outdoor unit relative to the combined nominal
capacity of the connected indoor units. In some designs, oversized indoor units may be unavoidable in the case where the smallest size
indoor unit available from LG is larger than what is necessary to satisfy the zone load. This scenario may also occur when an indoor unit
selection one size down from the selected unit is slightly short of fulfilling the design load requirements, and the designer must choose the
next largest size unit. Sometimes it is recommended to choose a larger capacity outdoor unit if the installation space is big enough. Also,
it may be prudent to oversize the outdoor unit to address those times when the weather conditions may exceed the design conditions, to
minimize the possibility of ventilation systems that causes the space temperature to drift outside design parameters, or when the indoor unit’s
entering air temperature falls outside the approved design temperature range.

Determine the Corrected Capacity
The corrected cooling / heating capacity is different from the rated cooling / heating capacity. The corrected capacity includes changes in
unit performance after considering design temperatures, available capacity that can be allocated from the outdoor unit, pressure drop due
to refrigerant line length, defrost operation in heating mode, and (if applicable) altitude. Depending on the location of the building, additional
capacity correction factors may need to be applied.
Using the Outdoor Unit Cooling and Heating Capacity Tables
Rated cooling capacity ratings are obtained with air entering the indoor unit at 80ºF dry bulb (DB) and 67ºF wet bulb (WB), and outdoor ambi-
ent conditions of 95ºF dry bulb (DB) and 75ºF wet bulb (WB). Rated heating capacity ratings are obtained with air entering the indoor unit at
70ºF dry bulb (DB) and 60ºF wet bulb (WB) and outdoor ambient conditions of 47ºF dry bulb (DB) and 43ºF wet bulb (WB).
To evaluate the total outdoor unit capacity at design conditions, using LATS Multi F software (preferred method) or reference the Perfor-
mance Data Capacity Tables found in the Multi F outdoor unit section in this manual. All design temperatures are not explicitly shown in the
charts, therefore, interpolation may be necessary to calculate the capacity for specific design conditions. Based on the premise that capacity
follows a linear curve, the following formula can be applied:
(y - y1) / (y2 - y1) = (x - x1) / (x2 - x1)
Where
y = Missing Capacity (Capacity at the Design Temperature).

y1 = Capacity at Lower Temperature (Smaller value of the two nearest published TC datapoints).
y2 = Capacity at Higher Temperature (Higher value of the two nearest published TC datapoints).
x = Design Temperature (Temperature not shown in published capacity tables).

x1 = (Smaller value of the two nearest published temperature datapoints).
x2 = (Larger value of the two nearest published temperature datapoints).

EQUIPMENT SELECTION PROCEDURE
Using the Indoor Unit Cooling and Heating Capacity Tables
The datapoints shown in the indoor unit cooling and heating capacity charts are based on (and convey) an indoor unit operating with maxi-
mum possible refrigerant flow from the outdoor unit and before any derates are applied. In other words, the capacities displayed reflect what
the indoor unit would produce if it was the only indoor unit that required capacity, and the outdoor unit did not have to allocate any capacity to
another indoor unit.
System operation with a combination of indoor units is not conveyed in these charts, however, the information can be used to calculate
indoor unit allocated capacity (without using the system combination tables). Simply calculate by using the formula:
Where
Qidu(combi) = Qodu(rated) x Qidu(rated)
ΣQidu(rated)
• The formula can be used to find individual indoor unit capacity for Multi F MAX systems.
• A more accurate method to determine expected capacity would be to apply the outdoor unit’s corrected capacity instead of rated
capacity.
Qidu(combi) = Individual Indoor Unit Combination Capacity.
Qodu(rated) = Outdoor Unit Rated Capacity.

Using the System Combination Tables
Multi F system combination tables illustrate how each indoor unit receives a percentage of total outdoor unit rated capacity. Allocation is
based on:
• Combinations of Non-Ducted Indoor Units
• Combinations of Ducted Indoor Units
• Combinations of Mixed Non-Ducted and Ducted Indoor Units
Multi F MAX system combination tables only show the total connected indoor unit capacity, but individual indoor unit capacity can be
calculated using the formula:
A more accurate method to determine expected capacity would be to apply the outdoor unit’s corrected capacity instead of rated capacity.

Altitude Correction Factor
The impact of air density must be considered on systems installed at a significant altitude above sea level, therefore, locally accepted
altitude correction factors must be applied.
Table 323: Outdoor Unit Frost Accumulation Factor (Heating)

.
There will be temporary reduction in capacity when frost / ice accumulates on the outside surface of the outdoor unit heat exchanger. The level
of capacity reduction depends on a number of factors, for example, outdoor temperature (°F DB), relative humidity (RH), and the amount of frost
present.

At 85% outdoor air relative humidity.
The frost accumulation factor does not account for effects of snow accumulation restricting airflow
through the outdoor unit coil.
Defrost Correction Factor for Heating Operation
The outdoor unit heating capacity may need to be adjusted for frost accumulation on air-cooled systems. If design day conditions are below
the dewpoint of the surrounding air, frost may not be a problem and no correction factor is needed. In certain weather conditions, however,
frost may form and accumulate on the air-cooled outdoor unit coil and impact the coils ability to transfer heat. If significant frost accumulates
on the outdoor unit coil, a defrost algorithm will start automatically. The timing between defrost periods is determined by the system’s ability
to achieve a target head pressure value.
Capacity and AHRI ratings tables do not factor in capacity reduction when frost has accumulated on the condenser coil, nor during defrost
operation.
Integrated heating capacity values can be obtained using the formula:
A = B x C
Where:
A = Integrated Heating Capacity.
B = Value found in the Capacity Table.
C = Correction Factor for Frost Accumulation Factor (from Table 101).
Check the Indoor and Outdoor Unit Selection(s)
Compare the corrected cooling and heating capacities to the load calculations. Is each capacity sufficient for the zone it serves?
For each indoor unit, the corrected capacity must be at least equal to the total of the cooling design load (plus ventilation load, if applicable)
for the space(s) served by the indoor unit. For each indoor unit, the corrected capacity also must be at least equal to the total of the heating
design load (plus ventilation load, if applicable) for the space(s) and / or thermal zones served by the indoor unit.
The outdoor unit selected should be large enough to offset the total cooling load for all spaces it serves (account for ventilation air cooling
load if the ventilation air has not been pretreated to room neutral conditions). The outdoor unit should also be large enough to offset the total
heating load for all spaces it serves.
If the corrected heating capacity ratio exceeds 100%, reselect the equipment, or change the system design by moving some of the load to
another system.
• Understand the design safety factors.
• Reference load calculations for actual cooling and heating capaci-
ties (applies in 99% of applications – consider total load when
latent load is greater than 30%).
• Verify that the sensible load of the zone is satisfied.
• Use caution when sizing to meet listed capacity specifications for
the scheduled manufacturer’s equipment.

application you would like to discuss, contact your LG sales rep.

ASHRAE Standards 62.1 and 62.2 (depending on if the building is residential or commercial), and local codes specify the minimum volume
of airflow that must be provided to an occupied space. Outdoor air is required to minimize adverse health effects, and it provides acceptable
indoor air quality for building occupants. Indoor units located within the zone typically require less airflow to condition the space. During the
design phase, refer to the airflow capabilities listed in the specification tables for each product. Choose the best method for the application
out of the five (5) ventilation options available.
Disclaimer
Although we believe that these building ventilation methods have been portrayed accurately, none of the methods have been tested, veried, or
evaluated by LG Electronics, U.S.A., Inc., In all cases, the designer, installer, and contractor should understand if the suggested method is used,
it is used at their own risk. LG Electronics U.S.A., Inc., takes no responsibility and offers no warranty, expressed or implied, of merchantability
or tness of purpose if this method fails to perform as stated or intended.
• For a complete copy of ASHRAE Standard 62.1 and 62.2, refer to the American Standard of Heating and Air Conditioning Engineers
(ASHRAE) website at www.ashrae.org.
Method 1: Natural Ventilation (Non-Ducted, Unconditioned Outdoor Air)
Natural ventilation devices, such as operable windows or louvers may be used to ventilate the building when local code permits.
Advantages
• Occupants control the volume of the ventilation air manually.
• Useful for historic buildings that have no ceiling space available for
outdoor air ductwork.
• May be used with the full lineup of Multi F indoor units.
Disadvantages
• In some locations, it may be difficult to control humidity levels when
windows are open.
• Thermal comfort levels may be substandard when windows are
open.
• Indoor units may have to be oversized to account for the added
heating and cooling loads when windows are open.
• Provides outdoor air to perimeter spaces only. Additional mechani-
cal ventilation system may be required to satisfy requirements for
interior spaces.
• Outdoor air loads may be difficult to calculate since the quantity of
outdoor air is not regulated.
• May affect indoor unit proper operation when open.

Method 2: Unconditioned Outdoor Air (Non-Ducted, Fan Assisted Ventilation)
When approved by local codes, the fan assisted ventilation method uses exhaust fans to remove air from the building, and outdoor air is
drawn into occupied spaces through a wall louver or gravity roof intake hood. Supply fans can also be used to push the outdoor air into the
space and building positive pressure will vent the exhaust air through louvers or roof-mounted exhaust hoods. Outdoor air is neither cooled
nor heated before entering the building.
Advantages
• Outdoor air may be manually controlled by the occupant or auto-
matic controls may be installed to open/close outdoor air dampers
or to turn on/off ventilation fans.
• Useful for large open spaces like warehouses, garages, and
workshops.
• Outdoor air volume is a known quantity. Air loads may be easier to
calculate since fans will regulate the amount of outdoor air.
• May be used with the full lineup of Multi F indoor units.
This may result in loss of building pressurization control, increasing inltration loads with adverse effects.
Disadvantages
• In some locations of the country, it may be difficult to control
humidity levels.
• Indoor units may have to be oversized to account for the added
heating/cooling loads when louvers/hoods are open.
• Hot, cold, and/or humid areas may be present if the outdoor air is
not evenly distributed to the different spaces.

Method 3: Unconditioned Outdoor Air Ducted to Indoor Units
Untreated outdoor air is channeled through a duct system that is piped to the return air duct on Multi F ducted indoor units or to the frame of
Multi F four-way cassettes.
Advantages
• May require less ductwork if indoor units are
placed near outdoor walls or a roof deck.
• Controls must be interlocked to shut off the
outdoor air supply fan when the space is
unoccupied.
• Third-party demand-control ventilation
controls may be installed to regulate outdoor
intake based on the CO

levels of the
occupied space.
Disadvantages
• Fan(s) will be required to push outdoor air to the indoor unit to overcome the additional
static pressure.
• Filter required to be added to the outdoor air duct.
• Ducted and four-way cassette models are the only indoor units that accept the connection
of an outdoor air duct to the unit case.
• In most cases, in lieu of using the factory mounted return-air thermistor on indoor units, a
remote wall temperature sensor or zone controller will be needed to provide an accurate
reading of the conditioned area temperature.
• Unconditioned outdoor air may affect indoor unit performance, which may necessitate
oversizing the indoor unit.
Outside air may ow backward through the return air-lter grille when the indoor unit fan speed slows or stops in response to changes in the
space load. This may result in captured particulate on the lter media being blown back into the conditioned space.

Method 4: Coupled Dedicated Outdoor Air (CDOA)
A separate, dedicated outdoor air system delivers air directly to a Multi F indoor unit or to the return air duct system. After mixing with the
return air stream, ventilation air passes through the indoor unit and into the conditioned space. The pretreatment system is capable of
filtering, conditioning, and dehumidifying outdoor air to room neutral conditions.
Advantages
• Indoor unit capacity may not need to be
increased because of outdoor air.
• Fan and filter system is centralized to the
main outdoor air unit.
Disadvantages
• Ducted and four-way cassette indoor units are the only models designed for direct
connection of an outside air duct.
• Ceiling space is required for ductwork.
• Failure of outdoor air may impact indoor unit operation.
• In lieu of using the factory mounted return-air thermistor, a remote wall temperature
sensor or zone controller may be required to provide an accurate conditioned space
temperature reading.
Outside air may ow backward through the return air-lter grille when the indoor unit fan speed is reduced or stops when the space load is
satised. This may result in captured particulate on the lter media being blown back into the conditioned space.

Method 5: Decoupled Dedicated Outdoor Air System (DDOAS)
Provide a separate, dedicated outdoor-air system designed to filter, condition, and dehumidify ventilation air and deliver it directly to the
conditioned space through a separate register or grille. This approach requires a separate independent ventilation duct system not
associated with the Multi F system.
Advantages
• Does not add additional heating or cooling loads to indoor units.
• May be used with the full lineup of Multi F indoor units.
• Failure of outdoor unit does not impact operation of indoor unit, the
resulting untreated air will be readily noticed by the occupants.
• The outdoor air unit may supply “neutral” air to the occupant space
even when the Multi F indoor unit fan changes speed or cycles on
and off. DDOAS controls do not have to be interlocked with the
Multi V F system.
• In lieu of installing localized smaller outside air treatment
equipment throughout the building, this method centralizes the
ventilation air source making service and filter changes easier and
less disruptive for the building occupants.
• Third-party demand control ventilation controls are more readily
accommodated.
• Indoor unit operation and performance will not be affected by the
condition of outdoor air.
Disadvantages
• Ceiling space is required to accommodate ductwork between the
outdoor air unit and ceiling diffusers.
LG recommends using the DDOAS method in all installations.

electric wires, audio and visual appliances, breaker / circuit panels, etc. If the frequency signal of the appliance is unstable, then install the
indoor unit a minimum of ten (10) feet away, and run the power and transmission cables through a conduit.
• An area that is level and with enough strength to bear the weight of the indoor unit(s).
• An area where operation sound won’t disturb occupants.
• An area that does not expose the indoor unit(s) to heat, water, steam, oil splattering or spray.
Selecting the Best Location for the Branch Distribution (BD) Unit
Branch Distribution (BD) units are used only with Multi F MAX systems to distribute the refrigerant from the outdoor unit to up to eight indoor
units. Select location indoors that will meet the following conditions:
• Within allowable parameters for proper connection to the Multi F MAX outdoor unit and indoor unit(s); refrigerant piping and wire lengths
must not exceed amounts specified by LG Electronics, U.S.A., Inc.
• No obstacles to air circulation around the unit; keep proper distances from ceilings, doorways, floor, walls, etc.
• Condensate drain piping is not required.
• Ensure there is enough space in the installation area for service purposes; install the refrigerant piping and electrical wiring system in an
easily accessible location.
• Do not install the BD unit in a location where it would be subjected to strong radiation heat from heat sources.
• Avoid an installation environment where the BD unit would be exposed to heat, water, steam, oil splattering or spray.
• Where high-frequency electrical noise / electromagnetic waves will not affect operation. Maintain proper distances between the BD unit(s)
and electric wires, audio and visual appliances, breaker / circuit panels, etc.
• Level where there is enough strength to bear the weight of the BD unit.
• Install the unit in a location where any sound it generates will not disturb occupants in the surrounding rooms.
When deciding on a location to place the outdoor unit, be sure to choose an area where run-off from defrost mode will not
accumulate and freeze on sidewalks or driveways.

If the outdoor unit is installed on a roof structure, be sure to level the unit. Ensure the roof structure and anchoring method are adequate for
the unit location. Consult local codes regarding rooftop mounting.

Planning for Snow and Ice
In climates that experience snow buildup, place the unit on a raised platform to ensure proper condenser airflow. The raised support platform
must be high enough to allow the unit to remain above possible snow drifts. Mount the unit on a field-provided snow stand at a minimum
height that is equal to the average annual snowfall, plus 20 inches. Design the mounting base to prevent snow accumulation on the platform
in front or back of the unit case. If necessary, provide a field fabricated hood to keep snow and ice and/or drifting snow from accumulating on
the coil surfaces. Use inlet and discharge duct or hoods to prevent snow or rain from accumulating on the fan inlet and outlet guards. Best
practice prevents snow from accumulating on top of the unit. Consider tie-down requirements in case of high winds or where required by
local codes.
Oceanside Installation Precautions
• Avoid installing the outdoor unit where it
would be directly exposed to ocean winds.
• Install the outdoor unit on the side of the
building opposite from direct ocean winds.
• Select a location with good drainage.
• Periodically clean dust or salt particles off of
the heat exchanger with water.
Additional anti-corrosion treatment may need
to be applied to the outdoor unit at oceanside
locations.
If the outdoor unit must be placed in a
location where it would be subjected to
direct ocean winds, install a concrete
windbreaker strong enough to block
any winds. Windbreaker height and
width should be more than 150% of the
outdoor unit, and be installed at least
27-1/2 inches away from the outdoor unit
to allow for airflow.
Ocean winds may cause corrosion, particularly on the condenser and evaporator ns, which,
in turn could cause product malfunction or inefcient performance.

set at a right angle to the wind direction.
Outdoor Unit Service Access and Allowable Clearances
Appropriate airflow through the outdoor unit coil is critical for proper unit operation.
• Include enough space for airflow and for service access. If installing multiple outdoor units, avoid placing the units where the discharge of
one unit will blow into the inlet side of an adjacent unit.
• No obstacles to air circulation around the unit; keep proper distances from ceilings, fences, floor, walls, etc. (Install a fence to prevent pests
from damaging the unit or unauthorized individuals from accessing it.)
• If an awning is built over the unit to prevent direct sunlight or rain exposure, make sure that the discharge air of the outdoor unit isn’t restricted.
When installing the outdoor unit, consider service, inlet, and outlet, and minimum allowable space requirements as illustrated in the following
diagrams.

Field-supplied elbows are allowed as long as they are designed for
use with R410A refrigerant. The designer, however, should be cau-
tious with the quantity and size of fittings used, and must account for
the additional pressure losses in equivalent pipe length calculation
for each branch. The equivalent pipe length of each elbow must be
added to each pipe segment.

Refrigerant Piping Design and Best Practices
MULTI

MAX
MULTI
F
Creating a Balanced / Quality Piping System
Unlike designing duct-work or chilled and hot water pipe systems where balancing dampers, ball valves, orifices, circuit setters, or other
flow control devices can be installed to modify or balance the flow of cooling medium, these cannot be used in a Multi F system. Therefore,
variable refrigerant flow systems have to be designed to be “self balanced.” Balanced liquid refrigerant distribution is solely dependent on
the designer using the correct pipe size for each segment. Pipe sizing considerations include pipe length, pipe segment pressure drop
relative to other pipe segments in the system, type and quantity of elbows, bends present, fitting installation orientation, and end use device
elevation differences.
Any eld changes, such as re-routing, shortening or lengthening a pipe segment, adding or eliminating elbows and/or ttings, re-sizing, adding,
or eliminating indoor units, changing the mounting height or moving the location of a device or tting during installation should be done with cau-
tion and ALWAYS VERIFIED in LATS MULTI F SOFTWARE before supplies are purchased or installed. Doing so ensures protable installation,
eliminates rework, and ensures easier system commissioning.
The designer should avoid creating excessive pressure drop. When liquid refrigerant is subjected to excessive pressure drop, liquid refrig-
erant will change state and “ash” to vapor. Vapor present in a stream of liquid refrigerant before reaching the indoor unit coil (or branch
distribution unit for Multi F MAX systems) results in a loss of system control and causes damage to the components. The pipe system must
be designed in a manner that avoids the creation of unwanted vapor.
Refrigerant Piping System Verification
To ensure that the refrigerant piping design is suitable for the system, a LATS refrigerant piping design software report must be provided with
every Multi F order. Following the installation, if any changes or variations to the design were necessary, an “as-built” LATS piping design
software report must be provided to LG prior to system commissioning. User should always check the LATS report actual pipe layout versus
pipe limits.
REFRIGERANT PIPING DESIGN
Manual Layout Procedure
1. Choose the location of the indoor units on the building drawing.
2. Choose the location of all Y-branch and branch distribution units (if a Multi F MAX system) and note them on the building drawing. Verify
that all fittings are positioned per the guideline limitations set forth in “Y-branch Kits” on page 363.
3. Plan the route for interconnecting piping. Draw a one-line depiction of the pipe route chosen on the building drawing.
4. Calculate the actual length of each pipe segment and note it on the building drawing.
5. Using the data obtained while selecting the system components, list the corrected cooling capacity next to each indoor unit on the
drawing.
6. Starting at the indoor unit located farthest from the outdoor unit, sum the corrected cooling capacity of all indoor units served by the pipe
segment for each branch and runout pipe (indoor units and branch distribution units [Multi F MAX systems only]). Record these values
next to each segment.
7. Verify the size of the liquid and vapor lines.
8. If a Multi F MAX system, refer to Cut-Sheets “Y-branch Kits” on page 379 and branch distribution units on page 373 to verify the part
number of each Y-branch and branch distribution unit based on the connected downstream nominal capacity served.
9. Calculate the equivalent pipe length in feet of each pipe segment. If a Multi F MAX system, Y-branch equivalent lengths should be totaled
with the upstream segment only. Use equivalent pipe length data when it is provided with field-purchased fittings. If not available, use
the data provided on page 360 to estimate the equivalent length of field-provided pipe and fittings for each segment. Equivalent lengths
should be totaled with the upstream segment only.
10. Verify if the equivalent pipe length complies with the limitations in the “Multi F and Multi F MAX Refrigerant Piping System Limitations”
tables on pages 360 and 361. If the limitations are exceeded, either reroute the pipe or change the location of the indoor unit, Y-branch
fittings and branch distribution units (if Multi F MAX systems), so the design conforms with all limitations.
11. If adjusted as per Step 10 above, verify again if the length of the design complies with the limitations set in “Multi F and Multi F MAX
Refrigerant Piping System Limitations” tables on pages 360 and 361.
12. Verify that the manually sized pipe design is acceptable using LATS Multi F. When entering the length of pipe segments in LATS Multi F
software, enter the equivalent pipe length. Account for the additional pressure drop created by elbows, valves, and other fittings present in
each segment by adding their respective equivalent pipe length to the actual pipe length.

LG Engineered Multi F MAX Y-Branch Kit
The LG supplied Y-Branch Kit PMBL5620 MUST be used when two
branch distribution units are connected on one Multi F MAX system.
Field-supplied fittings are not permitted. Each Y-Branch kit comes
with two (2) Y-branches (one for the liquid line and one for the vapor
line) and insulation covers.
Y-branches may be installed in horizontal or vertical configurations.
When installed vertically, position the Y-branch so the straight-
through leg is ±3° of plumb. When installed horizontally, position the
Y-branch so the take-off leg is level and shares the same horizontal
plane as the straight-through leg ±10° rotation.
Y-branches must be properly installed following instructions in the
applicable LG manual. Y-branches should always be installed with
the single port facing the outdoor unit and the two-port end facing
the branch distribution units. Do not install Y-branches backwards
as refrigerant flow cannot make U-turns. The Y-branch kit must be
located at least three (3) feet from the outdoor unit. Provide
a minimum of 20 inches between a Y-branch and the branch
distribution unit.
It is recommended that when a Y-branch is located in a pipe chase
or other concealed space, access doors should be provided for
inspection access.
The equivalent pipe length of each Y-branch (1.6′) must be added to
the main pipe segment entered into LATS piping design software.

Type ACR copper is the only approved refrigerant pipe material for
use with LG Multi F air conditioning products. ACR rated tubing is the
only type that ships with yellow caps. Approved tubing for use with
Multi V products will be marked “R410 RATED” along the length of
the tube.
• Drawn temper (rigid) ACR copper tubing is available in sizes 3/8
through 2-1/8 inches (ASTM B 280, clean, dry, and capped).
• Annealed temper (soft) ACR copper tubing is available in sizes 1/4
through 2-1/8 inches (ASTM B 280, clean, dry, and capped).
Tube wall thickness should meet local code requirements and be
approved for a maximum operating pressure of 551 psi. When bend-
ing tubing, use the largest radii possible to reduce the equivalent
length of installed pipe; also, bending radii greater than ten (10) pipe
diameters can minimize pressure drop. Be sure no traps or sags are
present when rolling out soft copper tubing coils.

Under normal operating conditions, the vapor pipe temperature of a
Multi F system can vary as much as 180°F. With this large
variance in pipe temperature, the designer must consider pipe
expansion and contraction to avoid pipe and fitting fatigue failures.
Refrigerant pipe, along with the insulation jacket, form a cohesive
unit that expands and contracts together. During system operation,
thermal heat transfer occurs between the pipe and the surrounding
insulation.
If the pipe is mounted in free air space, no natural restriction to
movement is present if mounting clamps are properly spaced and
installed. When the refrigerant pipe is mounted underground in a
utility duct stacked among other pipes, natural restriction to linear
movement is present. In extreme cases, the restrictive force of
surface friction between insulating jackets could become so great
that natural expansion ceases and the pipe is “fixed” in place. In this
situation, opposing force caused by change in refrigerant fluid/vapor
temperature can lead to pipe/fitting stress failure.
The refrigerant pipe support system must be engineered to allow
free expansion to occur. When a segment of pipe is mounted
between two fixed points, provisions must be provided to allow pipe
expansion to naturally occur. The most common method is the
inclusion of expansion Loop or U-bends mounted in the horizontal
plane. When expansion loops are placed in a vertical riser, the loop
is to be formed in a horizontal fashion resulting in a torsional move-
ment during expansion and contraction. Each segment of pipe has
a natural fixed point where no movement occurs. This fixed point is
located at the center point of the segment assuming the entire pipe
is insulated in a similar fashion. The natural fixed point of the pipe
segment is typically where the expansion Loop or U-bend should be.
Linear pipe expansion can be calculated using the following formula:
1. From Table 337, find the row corresponding with the actual length
of the straight pipe segment.
2. Estimate the minimum and maximum temperature of the pipe.
Typical pipe temperature change range: High Pressure Vapor:
ambient temperature to 215°F; Low Pressure Vapor: ambient to
35°F; Liquid pipe: ambient, 80°F, 110°F. Choose the two most
extreme. In the column showing the minimum pipe temperature,
look up the anticipated expansion distance. Do the same for the
maximum pipe temperature.
3. Calculate the difference in the two expansion distance values.
The result will be the anticipated change in pipe length.
Example:
A Multi F MAX system is installed and the design shows that there
is a 100 foot straight segment of tubing between a Y-branch and
a branch distribution unit. The system operates 24 hours per day.
In heating, this pipe transports hot gas vapor to the indoor units at
120°F. In cooling, the same tube is a suction line returning refriger-
ant vapor to the outdoor unit at 40°F. Look up the copper tubing
expansion at each temperature and calculate the difference.
Vapor Line
Transporting Hot Vapor: 100 ft. pipe at 120°F = 1.40 in.
Transporting Suction Vapor: 100 ft. pipe at 40°F = 0.40 in.
Anticipated Change in Length: 1.40 in. – 0.40 in. = 1.00 in.
Liquid Line
The liquid temperature remains the same temperature; only the
direction of flow will reverse. Therefore, no significant change in
length of the liquid line is anticipated.
When creating an expansion joint, the joint depth should be a
minimum of two times the joint width. Although different types of
expansion arrangements are available, the data for correctly sizing
an expansion loop is provided in Table 338. Use soft copper with
long radius bends on longer runs or long radius elbows for shorter
pipe segments. Using the anticipated linear expansion (LE) distance
calculated, look up the Expansion Loop or U-bend minimum design
dimensions. If other types of expansion joints are chosen, design
per ASTM B-88 Standards.

Field-Provided Isolation Ball Valves
LG recommends installing field-supplied ball valves with Schrader ports at each indoor unit. Full-port isolation ball valves with Schrader ports
(positioned between valve and indoor unit) rated for use with R410A refrigerant should be used on both the liquid and vapor lines.
If valves are not installed and a single indoor unit needs to be removed or repaired, the entire system must be shut down and evacuated. If
isolation ball valves are installed, and an indoor unit needs to be repaired, the unaffected indoor units can remain operational with the proper
combination ratio. Reclamation of refrigerant, then, can be restricted to a single indoor unit.
For Multi F MAX systems, position valves with a minimum distance of three (3) to six (6) inches of pipe on either side of the valve, and placed
between six (6) and twelve (12) inches from the first upstream Y-branch or branch distribution unit. If ball valves are installed away from the
first Y-branch and / or branch distribution unit and closer to the indoor unit, oil may accumulate where it cannot be returned to the outdoor
unit and may cause a shortage of oil in the compressor.
Valves shall be easily accessible for service. If necessary, install drywall access doors or removable ceiling panels, and position the valves
to face the access door or ceiling panel opening. Mount valves with adequate space between them to allow for placement of adequate pipe
insulation around the valves. Recommended best practice is to clearly label and document locations of all service valves, Y-branches, and
branch distribution units. The equivalent pipe length of each ball valve must be added to each pipe segment entered into the LATS program.

Below an obstacle.
Obstacles
When an obstacle, such as an I-beam or concrete T, is in the path
of the planned refrigerant pipe run, it is best practice to route the
pipe over the obstacle. If adequate space is not available to route
the insulated pipe over the obstacle, then route the pipe under the
obstacle. In either case, it is imperative the horizontal section of pipe
above or below the obstacle be a minimum of three (3) times greater
than the longest vertical rise (or fall) distance.

Pipe Slope
The horizontal pipe slope cannot exceed 10° up or down.
In-line Refrigeration Components
Components such as oil traps, solenoid valves, filter-dryers, sight glasses, tee fittings, and other after-market accessories are not permitted
on the refrigerant piping system between the outdoor units and the indoor / branch distribution units. Multi F and Multi F MAX systems are
provided with redundant systems that assure oil is properly returned to the compressor. Sight-glasses and solenoid valves may cause vapor
to form in the liquid stream. Over time, dryers may deteriorate and introduce debris into the system. The designer and installer should verify
the refrigerant piping system is free of traps, sagging pipes, sight glasses, filter dryers, etc.
No Pipe Size Substitutions
Use only the pipe size selected by the LATS Multi pipe system design software or as conveyed in the product installation instructions. Using
a different size is prohibited and may result in a system malfunction or failure to work at all.
Due to our policy of continuous product innovation, some specications may change without notication.

Pipe supports should never touch the pipe wall; supports shall be installed outside
(around) the primary pipe insulation jacket. Insulate the pipe first because pipe supports
shall be installed outside (around) the primary pipe insulation jacket. Clevis hangers
should be used with shields between the hangers and insulation.
Field provided pipe supports should be designed to meet local codes. If allowed by
code, use fiber straps or split-ring hangers suspended from the ceiling on all-thread rods
(fiber straps or split ring hangers can be used as long as they do not compress the pipe
insulation). Place a second layer of insulation over the pipe insulation jacket to prevent
chafing and compression of the primary insulation within the confines of the support pipe
clamp.
A properly installed pipe system will have sufficient supports to avoid pipes from sag-
ging during the life of the system. As necessary, place supports closer for segments
where potential sagging could occur. Maximum spacing of pipe supports shall meet
local codes. If local codes do not specify pipe support spacing, pipe shall be supported
a maximum of 5 feet on center for straight segments of pipe up to 3/4” outside diameter
size.
Wherever the pipe changes direction, place a hanger within twelve (12) inches on one
side and within twelve to nineteen (12 to 19) inches of the bend on the other side. Sup-
port piping at indoor units as shown. Support Y-Branch fittings as shown.
A properly installed pipe system should be adequately supported to avoid pipe sagging. Sagging pipes
become oil traps that lead to equipment malfunction.

Pipe Sleeves at Penetrations
LG requires that all pipe penetrations through walls, floors, and

shall be routed inside a protective sleeve to prevent insulation dete-
rioration. Also follow federal, state, and local regulations and codes
when choosing a sleeve type.

Sleeve diameter (total): 3.1" minimum
Diameter of penetrations shall be determined by pipe diameter
plus the thickness of the insulation.
Underground Refrigerant Piping
Refrigerant pipe installed underground should be routed inside a
vapor tight protective sleeve to prevent insulation deterioration and
water infiltration. Refrigerant pipe installed inside underground
casing must be continuous without any joints. Underground refriger-
ant pipe must be located at a level below the frost line.

Brazing Practices
1. All joints are brazed in the field. Multi F refrigeration system components
contain very small capillary tubes, small orifices, electronic expansion valves,
oil separators, and heat exchangers that can easily become blocked.
• Store pipe stock in a dry place; keep stored pipe capped and clean.
• Blow clean all pipe sections with dry nitrogen before assembly.
2. Proper system operation depends on the installer using best practices and
utmost care while assembling the piping system.
• Use adapters to assemble different sizes of pipe.
• Do not use flux, soft solder, or anti-oxidant agents.
• Use a tubing cutter; do not use a saw to cut pipe. De-burr and clean all cuts before assembly.
3. Brazing Joints:
• Use a dry nitrogen purge operating at a minimum pressure of three (3) psig and maintain a steady flow.
• Use a 15% silver phosphorous copper brazing alloy to avoid overheating and produce good flow.
• Protect isolation valves, electronic expansion valves, and other heat-sensitive control components from excessive heat with a wet rag or a
heat barrier spray product

Refrigerant Piping System Insulation
All refrigerant piping including Y-branch connections, field-provided isolation ball valves, service valves, and elbows shall be completely
insulated using closed cell pipe insulation.
To prevent heat loss/heat gain through the refrigerant piping, all refrigerant piping including liquid lines and vapor lines shall be insulated
separately. Insulation shall be a minimum 1/2″ thick, and thickness may need to be increased based on ambient conditions and local codes.
All insulation joints shall be glued with no air gaps. Insulation material shall fit snugly against the refrigeration pipe with no air space between
it and the pipe. Insulation passing through pipe hangers, inside conduit, and/or sleeves must not be compressed. Protect insulation inside
hangers and supports with a second layer. All pipe insulation exposed to the sun and outdoor elements shall be properly protected with PVC,
aluminum vapor barrier, or alternatively placed in a weather-resistant enclosure such as a pipe rack with a top cover; and meet local codes.
Pay special attention to insulating the pipes installed in the ceiling plenum.
LG-provided Y-branches are shipped from the factory with pre-formed peel-and-stick foam insulation jackets, with a 1.84 lb./ft.
3
density, 1/2″
thickness, and meet UL94 MF-1 flammability.
The design engineer should perform calculations to determine if the factory-supplied insulation jackets are sufficient to meet local codes and
avoid sweating. Maximum refrigerant piping temperature is +227°F; minimum refrigerant piping temperature is -4°F. Add additional insulation
if necessary. Check the fit of the insulation jacket after the header fitting and all run-out pipes are installed. Mark all pipes at the point where
the insulation jacket ends. Remove the jacket. Install field provided insulation on the run-out and main trunk pipes first. Install the LG-pro-
vided insulation plugs on the ends of all unused header ports. Peel the adhesive glue protector slip from the insulation jacket and install the
clam-shell jacket over the fitting.

Condensate Drain Piping
Outdoor Units
Outdoor unit requires condensate drain piping. Condensate drain pipe is constructed with materials approved by local code. See pages 353
to 358 for information in reference to outdoor unit placement and condensate drainage.
Condensate Drain Piping
Indoor Units
All indoor units generate water during cooling operation, therefore, how to properly handle this condensation must be considered. Some
indoor units include factory-installed drain pumps; others apply the gravity drain method.
Depending on the location of the indoor unit, condensation can be drained directly to the outside of the building, or a common indoor unit
drainage piping system can be installed, both incorporating PVC piping.

Common Indoor Unit Drainage System
It is usual work practice to connect individual indoor unit drain pipes to one common indoor unit drainage system. The diameter of the com-
mon vertical drain pipe should be as large as necessary. (For systems with <80,000 Btu/h total capacity of all connected indoor units, the
standard size for the common vertical drain pipe is 0.98 ID, in. and 1.26 OD, in.) The diameter of the horizontal pipe should be the same
or larger than the vertical drain pipe. To avoid property damage in the event of the primary drain becoming clogged, and to optimize drain
system performance, it may be prudent to install a secondary drain line. Design the drain system to plan for winter operation (condensate line
may freeze up if condensate does not properly drain away). Drain all generated condensate from the external condensate pan to an appropri-
ate area. Install a trap in the condensate lines as near to the indoor unit coil as possible; to prevent overflow the outlet of each trap should be
positioned below its connection to the condensate pan. All traps should be primed, insulated, and leak tested if located above an inhabited
space.

• It is recommended that a dedicated drain pipe be installed for the air conditioning sys-
tem. If the indoor unit drainage system is shared with a rainwater drain, waste water,
or any other type of building drain system, back flow, leaks, ice may form, or noxious
odors may be present.
• Install a trap if the drain access to the outside faces an undesirable location (i.e., sew-
er), otherwise, noxious odors may infiltrate the air conditioning system.
Figure 86:Example of a Common Indoor Unit Drainage System.
Drain Leak Test
A leak test should be performed 24 hours after the drainage system
has been installed. Only use water for the test; other liquids are
unacceptable.
Drain Pipe Insulation
To prevent condensate from forming on the drain piping, install field-
supplied 0.4 inch thick polyethylene. The insulation should be securely
fastened with all connected joints and ends properly covered.

• Only qualified technicians—in accordance with federal, state, and local codes, and manufacturer product diagrams and requirements—
should install the power wiring and communication cables.
• Use only copper wiring that is stranded, shielded with the wires separately insulated.
• Do not use a multi-conductor cable with more than five (5) wires in one (1) core.
• Power wiring and communications cable sizes must comply with applicable federal UL / ETL, state, and local codes.
• Verify that the branch switch and circuit breaker are set to OFF before installing the wiring system.
• Do not operate the air conditioning system until the refrigerant piping installation is complete. Operating the system before refrigerant
piping is finalized may damage the compressor.
• Install a ground wire for the outdoor units, indoor units, and branch distribution units.
• Install a main shutoff switch or circuit breaker that interrupts all power sources simultaneously (circuit breaker should be resistant to
electromagnetic currents).
• To avoid the possibility of explosion, fire, etc., do not connect the ground wiring to gas or sewage pipes, lightening rods, and telephone
wires. Use clamps to prevent the wires from touching the piping.
• Use ring terminals to attach the wiring. Verify that all power wiring and communications cable terminals are securely attached; ensure
enough slack is included in the wiring and cables to avoid damaging the connections.
• Use a conduit to protect the power wiring.
• Do not install a phase-advancing capacitor; the outdoor unit may overheat.

Figure 98:Example of Power Wiring and Communications Cable Terminations.• Find the outdoor unit terminal block by unscrewing the
control access panel.
• Side panel of the outdoor unit has knockout holes for
the conduits. After install is complete, seal up any gaps
between the panel and the conduits.
• Clamp is included near the terminal block to help protect
the connections from strain on the cables.
• Always have a trained technician properly ground
the outdoor unit. If the outdoor unit is not properly
grounded, there is a risk of electric shock.
• Use a conduit for the power wiring.
• The communications cable should be separated and
isolated from the outdoor unit power wiring, comput-
ers, radio and television broadcasting facilities, as
well as medical imaging equipment.
Due to our policy of continuous product innovation, some specications may change without notication.

General Specifications
• Wired remote controllers can be connected to all indoor unit types.
• Wireless controllers can be used in conjunction with wired remote
controllers.
• A dry contact unit can be connected with a central controller
simultaneously.
- The master indoor unit is recognized by the dry contact unit and
the central controller.
- Group Control only available for indoor units manufactured after
February 2009.
- The central controller can control indoor units after setting the
address of the master indoor unit only.
- Slave indoor unit cannot be individually controlled by central
controller.
- Slave indoor unit will operate like master indoor unit.
• If an error occurs with the indoor unit, the error will be displayed on
the wired remote controller.
• The following functions are available with group control:
• Selection of operation options (operation/mode/set temperature)
• Control of air flow rate (High/Medium/Low)
Communication Cables Between Multiple Indoor Units Operating as a Group
(Group Control)
1. If any indoor units were specified to operate in unison, use
one (or multiple) three-core Group Control Kit (sold separately)
containing extension and Y-splitter cables. One (1) group control
cable kit for each indoor unit in the group except for the last
indoor unit.
2. Always use an LG provided group control communications cable
(Group Control Kit; sold separately) between the indoor unit and
the wall-mounted zone controller.
3. NEVER splice, cut, or extend cable length with field provided
cable.
4. A maximum of 16 indoor units can be connected to a wired
remote controller (maximum wire length: 164 feet). Before
running cable, decide which indoor unit will be the “Master;” set
the remaining as “Slave.” The zone controller will be connected
to the “Master.”
5. Identify each indoor unit operating as a group as “Master” or
“Slave”. Adjust the pertinent DIP switch at each indoor unit. On
wall mounted indoor unit models, set the assignment using the
wireless remote controller.
6. Use a daisy chain configuration and connect all of the group’s
indoor units together starting at the “Master” unit.
