LG AIR CONDITIONER
TECHNICAL SOLUTION (LATS)
LG Air Conditioner Technical Solution (LATS) Software
A properly designed and installed refrigerant piping system is critical
to the optimal performance of LG air-conditioning systems. To assist
engineers, LG offers, free of charge, LG Air Conditioner Technical
Solution (LATS) software—a total design solution for LG air condi-
tioning systems. Contact your LG Rep for the best software program
for your application.
To reduce the risk of designing an improper applied system or one that
will not operate correctly, LG requires that LATS software be used on all
projects.
Formats
LATS is available to LG customers in two user interfaces: LATS HVAC and LATS Revit. Both LATS formats are available through
www.myLGHVAC.com, or contact an LG Sales Representative.
LATS HVAC is a Windows
®
-based application that aids engineers in designing LG Variable Refrigerant Flow (VRF), Multi F / Multi F MAX,
Single-Zone, DOAS, and Energy Recovery Ventilator (ERV) systems.
*Windows
®
is a registered mark of Microsoft
®
Corporation.
LATS Revit integrates the LG LATS program with Revit
®
software**. It permits engineers to layout and validate LG VRF, Multi F / Multi F
MAX, Single-Zone, and DOAS directly into Revit drawings.
**Revit
®
is a registered mark of Autodesk, Inc.
Features
All LG product design criteria have been loaded into the program, making LATS simple to use: double click or drag and drop the component
choices. Build systems in Tree Mode where the refrigerant system can be viewed. Switch to a Schematic diagram to see the electrical and
communications wiring.
LATS software permits the user to input region data, indoor and outdoor design temperatures, modify humidity default values, zoning, specify
type and size of outdoor units and indoor units, and input air flow and external static pressure (ESP) for ducted indoor units.
The program can also:
• Import building loads from a separate Excel file.
• Present options for outdoor unit auto selection.
• Automatically calculate component capacity based on design
conditions for the chosen region.
• Verify if the height differences between the various system
components are within system limits.
• Provide the correct size of each refrigerant piping segment and LG
Y-Branches and Headers.
• Adjust overall piping system length when elbows are added.
• Check for component piping limitations and flag if any parameters
are broken.
• Factor operation and capacity for defrost operation.
• Calculate refrigerant charge, noting any additional trim charge.
• Suggest accessories for indoor units and outdoor units.
• Run system simulation.
Features depend on which LATS program is being used, and the type of system being designed. Contact your LG representative for the best soft-
ware program for your application.

LG AIR CONDITIONER
TECHNICAL SOLUTION (LATS)
LATS Generates a Complete Project Report
LATS software also generates a report containing project design parameters, cooling and heating design data, system component perfor-
mance, and capacity data. The report includes system combination ratio and refrigerant charge calculations; and provides detailed bill of
material, including outdoor units, indoor units, control devices, accessories, refrigerant pipe sizes segregated by building, by system, by pipe
size, and by pipe segments. LATS can generate an Excel GERP report that can be imported into the LG SOPS pricing and ordering system.
Proper Design to Install Procedure
LG encourages a two report design-to-install-procedure. After the design engineer determines building / zone loads and other details, the
engineer opens the LATS program and inputs the project’s information. When the design is complete, the “Auto Piping” and “System Check”
functions must be used to verify piping sizes, limitations, and if any design errors are present. If errors are found, engineers must adjust the
design, and run Auto Piping and System Check again. When the design passes the checks, then the engineer prints out a project “Shop
Drawing” (LATS Tree Diagram) and provides it to the installing contractor. The contractor must follow the LATS Tree Diagram when building
the piping system, but oftentimes the design changes on the building site:
• Architect has changed location and/or purpose of room(s).
• Outdoor unit cannot be placed where originally intended.
• Structural elements prevent routing the piping as planned.
• Air conditioning system conflicts with other building systems (plumbing, gas lines, etc.).
The contractor must mark any deviation from the design on the Shop Drawing, including as-built straight lines and elbows. This “Mark Up”
drawing must be returned to the design engineer or Rep, who must input contractor changes into the LATS file. (Copy the original LATS soft-
ware file, save and rename as a separate file, and modify all piping lengths by double-clicking on each length and editing information.) Like
the shop drawing, the Auto Piping and System Check must also be run on this new “As Built” drawing. The design engineer or Rep must then
provide the final As Built file to the contractor. The Mark Up version must be compared to the As Built version for:
• Differences in pipe diameter(s). If incorrect diameters have been installed, the piping must be changed out. If pipe diameters have changed,
check if Y-Branches will also need to be changed.
• Changes to outdoor unit and indoor unit capacities. Capacities changes will impact line length changes.
• Additional refrigerant charge quantity (“Trim Charge”). Trim charge will change if piping lengths and diameters change. The As Built version
must reflect installed piping lengths to ensure correct trim charge.
All documents submitted by the contractor, as well as the Shop Drawing and the As Built Drawing files must be provided for commissioning
purposes. Model and serial numbers for all system components must also be submitted. If the steps previously detailed are not followed, and
all documents are not provided to the commissioning agent, the project runs the risk of not being commissioned and voiding any limited war-
ranty LG offers on the equipment.

For single zone systems, calculate the equivalent length of the liquid line from the outdoor unit to the indoor unit. Also, determine the eleva-
tion difference of the indoor unit above or below the outdoor unit. Find corresponding cooling or heating capacity correction factors as shown
below. Multiply the correction factors by the cooling or heating capacity obtained from the capacity table using design conditions. The resul-
tant is the NET cooling or heating capacity.

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 will need to be adjusted for frost accumulation on air-cooled systems. If design day conditions are below
the dewpoint of the surrounding air, frost will not be a problem and no correction factor is needed. In certain weather conditions, however,
frost will 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 at right).
&KHFNWKH,QGRRUDQG2XWGRRU8QLW6HOHFWLRQV
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 must 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 must also be large enough to offset the total heat-
ing 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 capacities (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.

Installing in an Area Exposed to Unconditioned Air
In some installation applications, areas (floors, walls) in some rooms will be exposed to unconditioned air (room will be above or next to an
unheated garage or storeroom). To countermeasure:
• Verify that carpet is or will be installed (carpet will increase the temperature by three degrees).
• Add insulation between the floor joists.
• Install radiant heat or another type of heating system to the floor.

Planning for Snow and Ice
To ensure the outdoor unit operates properly, certain measures are required in locations where there is a possibility of heavy snowfall or
severe windchill or cold:
1. Prepare for severe winter wind chills and heavy snowfall, even in areas of the country where these are unusual phenomena.
2. Position the outdoor unit so that its airflow fans are not buried by direct, heavy snowfall. If snow piles up and blocks the airflow, the sys-
tem will malfunction.
3. Remove any snow that has accumulated four (4) inches or more on the top of the outdoor unit.
4. In climates that will experience significant snow buildup, mount the outdoor unit on a raised, field-provided platform or stand. The raised
support platform must be high enough to allow the unit to remain above possible snow drifts, and must be higher than the maximum antici-
pated snowfall for the location.
5. Design the mounting base to prevent snow accumulation on the platform in front or back of the unit frame.
6. Provide a field fabricated snow protection hood to keep snow and ice and/or drifting snow from accumulating on the coil surfaces.
7. To prevent snow and heavy rain from entering the outdoor unit, install the condenser air inlets and outlets facing away from direct
winds.
8. Consider tie-down requirements in case of high winds or where required by local codes.
CAUTION
When deciding on a location to place the outdoor unit, be sure to choose an area where run-off from defrost will not accumulate and freeze on side-
walks or driveways, which will create unsafe conditions.
Choose an area where run-off from defrost mode will not accumulate and freeze on sidewalks or driveways. Properly install and insulate any drain
hoses to prevent the hose from freezing, cracking, leaking, and damaging the outdoor unit.
Tie-Downs, Lightning Protection, and
Wind Protection
7LH'RZQV
• The strength of the roof must be checked before installing the
outdoor units.
• The strength of the outdoor unit frames is adequate to be used with
field-provided wind restraint tie-downs.
• If the installation site is prone to high winds or earthquakes, when
installing on the wall or roof, securely anchor the mounting base
using a field-provided tie-down configuration approved by a local
professional engineer.
• The overall tie-down configuration must be approved by a local
professional engineer.
Always refer to local code when using a wind restraint system.
Lightning Protection
• To protect the outdoor unit from lightning, it must be placed within
the specified lightning safety zone.
• Power cable and communication cable must be installed five (5)
feet away from lightning rod.
• A high-resistance ground system must be included to protect
against induced lightning or indirect strike.

• 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.
If the outdoor unit must be placed in a location
where it would be subjected to direct ocean winds,
install a concrete windbreak strong enough to
block any winds. Windbreaker height and width
must be more than 150% of the outdoor unit, and
be installed at least 14 to 28 inches away from the
outdoor unit to allow for airflow (depending on the
location and outdoor unit size).
Additional anti-corrosion treatment may need to be applied to the outdoor unit at oceanside locations.
Ocean winds will cause corrosion, particularly on the

If the outdoor unit is placed on a roof, position it with the compressor
end (no coil surface) in the direction of the prevailing wind as shown
in the figure at right. In cooler climates, it may be beneficial to posi-
tion the unit in direct sunlight to assist with defrost operations.
If the outdoor unit is not placed on a roof, place it on the leeward
side of the building or in a location where the unit will not be ex-
posed to constant wind.
If placement exposes the unit to constant wind activity, construct a
wind break in front of the unit. Follow the placement guidelines set
forth in “Clearance Requirements”.

Proper clearance for the outdoor unit coil is critical for proper unit operation. When installing the outdoor unit, consider service, inlet and
outlet and minimum allowable space requirements as illustrated in the diagrams on the page below.
• 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.
• 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.
•
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.)

Minimum Clearance Requirements for Single Fan Outdoor Units
Specific clearance requirements in the diagram below are for single fan outdoor units. The figure below shows the overall minimum clear-
ances that must be observed for safe operation and adequate airflow around the outdoor unit.
When placing the outdoor unit under an overhang, awning, sunroof or other “roof-like structure”, observe the clearance requirements (as
shown in Cases 1 and 2) for height in relation to the unit. To have successful service access to the outdoor unit, see the figure below for
minimum spacing. When installing multiple outdoor units, see Cases 4 and 5 for correct spacing requirements.

INSTALLING OUTDOOR UNITS INDOORS
Installing Outdoor Units Indoors
Single Zone outdoor units are engineered to be mounted outdoors and include technology designed to minimize the negative effects of winter
weather’s freezing rain, sleet, and snow. Some building projects, however, necessitate placing the HVAC outdoor units indoors:
• Lack of ground space.
• Lack of an appropriate outdoor location that meets system design requirements.
• When mounting on the roof is not an option due to a lack of roof space.
• Roof warranty will be voided if mechanical equipment is placed on the membrane.
• On retrofit projects, a former chiller / boiler / air handler equipment room, mechanical area, or penthouse already exists.
• To curtail the potential need for redundant zone heating devices such as wall-fin radiators or duct heaters.
• In extremely cold environments where there is a significant amount of run-time at temperatures well below freezing outside the outdoor unit
ambient air temperature range published in this engineering manual.
Benefits of Installing Outdoor Units Indoors
• Shelters the outdoor unit from direct exposure to prevailing winds that decrease the heating capability of the outdoor unit.
• Protects equipment from freezing precipitation and / or potential ice build-up that could hinder unit operation.
• Maintains coil heat transfer efficiency by reducing the number of and shortening the cycle time for defrost operation.
• Easier maintenance and servicing during inclement weather.
• When mounted in a fully enclosed space, limiting the ambient air temperature will allow the Single Zone system designer to eliminate over-
sizing.
• The outdoor unit to compensate for loss of capacity at low ambient temperatures.
• Will also curtail the need to provide inefficient redundant zone heating devices such as wall-fin radiators and second-stage ancillary heating
devices.
Design Considerations Include:
• Enclosure types and elements such as louvers (see next page), rain hoods, dampers and controls, heating methods and sizing of heating
devices.
• Heating strategies.
• Duct design.
• Condensate handling.
General Guidelines
• Follow ASHRAE 62.1 design guidelines.
• Depending on the project / application, a roof over the outdoor units in combination with a wind break will be all that is necessary.
• Consider the potential for snow accumulation near louvers / roof openings. Outside air intakes and discharge ducts / louvers must be engi-
neered to clear anticipated snow accumulation levels by at least one (1) foot.
• In situations where operation is anticipated at temperatures lower than the product’s minimum operating temperature, ancillary heat must
be provided to heat the outdoor unit coils to ensure continuous compressor operation and heating.
It may be necessary to use a field-fabricated air guide to prevent discharge air from short-cycling back to the coil inlet.
• Consider the direction of prevailing winds and opening placement. If possible, locate inlet openings upwind of discharge openings and other
exhaust outlets.
• When inlet and outlet openings are placed on the same wall, minimum distance between the two openings must be approximately three (3)
feet (minimum distance varies significantly with variations in outlet opening face velocity).
• If roof-mounted ventilation openings are used, strategically locate the inlet ventilation opening(s) upwind of the outlet opening(s).
• Discharge and supply ductwork must be designed to avoid weather related long periods of water entrainment.

Figure 34: Louver Recommendations.
Table 62: Using “S” Type Louvers.
Provide a means to drain the condensate generated during heating mode and defrost cycle in addition to rainwater that infiltrates the inlet
louver enclosed area.
• Install a field-provided drain pan under the outdoor units and provide a path to a nearby floor drain.
• If the ambient air temperature is expected to drop below 32°F in the enclosure, heat the bottom surface of the pan, drain line, and floor
drain so that the condensate does not freeze before reaching the drain.
Louver Recommendations for Outdoor Unit Enclosure
Allow for ventilation intake and exhaust air based on maximum outdoor unit fan capacity.
• Select the size, type and orientation of architectural louvers with adequate “net free area” face velocity to ensure the total external static
pressure from the outdoor unit fan does not exceed design limitations (see specification data tables).
•
No obstructions must be placed in front of the louver that could hamper the free flow (throw) of air.
• Roof top openings and / or discharge and supply louvers must be equipped with screens to prevent bird and insect infiltration.
For louver recommendations, see below and on the next page.
As always, the best solution for each project balances acceptable heating performance (considering local weather conditions), capital costs,
life cycle energy consumption, and limitations set forth by local building codes.
When deciding on a location to place the outdoor unit, be sure to choose an area where run-off from defrost will not accumulate and freeze on walk-
ways, which will create unsafe conditions.

Additional Refrigerant Charge
Each outdoor unit is factory charged (nameplate charge) for the evaporator as well as having a standard foot line (for each single zone
system; listed in the specification tables). Any time a line set is used longer then the standard foot line set length for the single zone system,
the refrigerant charge has to be adjusted.
The charge must be adjusted on the ounces of R32 (listed in the specification tables) per foot based on how many feet of piping are added.
The factory charge accommodates pipe lengths up to the standard (no additional refrigerant) length without requiring refrigerant removal.
See table below for information on the additional refrigerant charges necessary for longer piping lengths. Refer to the previous page for
maximum piping length and additional charge amount per additional foot of pipe length.

Approved piping for use with LG Single Zone products will be marked “R32 RATED” along the length of the pipe. Piping wall thickness must
meet local code requirements and be approved for a maximum operating pressure of 626 psi. When bending piping, try to keep the number
of bends to a minimum, and use the largest radii possible to reduce the equivalent length of installed piping; also, bending radii greater than
ten (10) piping diameters can minimize pressure drop. Be sure no traps or sags are present.
For Single Zone Systems
LG prefers the use of ACR copper piping rated at the system working pressure was used.
Always properly support the piping as per the instructions on page 100.

Refrigerant Piping Design
97
Under normal operating conditions, the vapor pipe temperature of
a Single Zone System can vary as much as 280°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. 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 tem-
perature 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 expan-
sion to naturally occur. The most common method is the inclusion
of expansion Loop or U-bends. 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 must be.
Linear pipe expansion can be calculated using the following formula:
1. From the “Linear Thermal Expansion of Copper Tubing in Inches”
Table on the next page, find the row corresponding with the actual
length of the straight pipe segment.
2. Estimate the minimum and maximum temperature of the pipe.
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.
General Example:
A system is installed and the design shows that there is a 100 foot
straight segment of tubing between an indoor unit and the outdoor
unit. 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 refrig-
erant 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 relatively 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 height must 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 the “Radii of Coiled Expansion
Loops and Developed Lengths of Expansion Offsets” Table on the
next page. 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 expan-
sion joints are chosen, design per ASTM B-88 Standards.

See table on next page for precalculated anticipated expansion for various pipe sizes and lengths of refrigerant tubing.
To find the anticipated expansion value:
1. From the table on the next page, find the row corresponding with the actual feet of the straight pipe segment.
2. Estimate the minimum and maximum temperature of the pipe.
3. In the column showing the minimum pipe temperature, look up the anticipated expansion distance corresponding to the segment length.
Do the same for the maximum pipe temperature.
4. Calculate the difference in the two expansion distance values. The result will be the change in pipe length.

No Pipe Size Substitutions
Use only the pipe size selected by the information in this manual. Using a different size is prohibited and will result in a system malfunction or
failure to work at all.
No In-line Refrigeration Components
Components such as oil traps, solenoid valves, filter-driers, sight glasses, tee fittings, and other after-market accessories are not
permitted on the refrigerant piping system between the outdoor units and the indoor units. LG Single Zone systems are provided with
redundant systems that make sure oil is properly returned to the compressor. Sight-glasses and solenoid valves will cause vapor to form in
the liquid stream. Over time, driers will deteriorate and introduce debris into the system. The designer and installer must verify the refrigerant
piping system is free of traps, sagging pipes, sight glasses, filter driers, etc.
Field-Provided Isolation Ball Valves
LG maintains a neutral position on using isolation valves in LG HVAC refrigerant piping systems. LG does not endorse any manufacturer of
isolation valves. It is recognized that installing isolation valves will simplify future maintenance requirements, and, if used, considerations
must be taken including, but not limited to, the following:
• Pressure drops for any component used, including isolation valves, must be known in equivalent pipe length and calculated into the total
and segment equivalent piping lengths and compared to product design limitations.
• In all cases, materials must be suitable for the application and any applicable codes, including, but not limited to, diameter and wall thick-
ness continuity per ACR standards.
Failure to do so will cause significant performance degradation. Proper leak checks must be performed. Using isolation valves does not
automatically void any LG product warranty, however, a limited warranty will be voided in whole or part if any field supplied accessory fail in
any way that causes product failure.
Using Elbows
Field-supplied elbows are allowed if they are long radius and designed for use with R32 refrigerant. The designer and installer, however,
must be cautious 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 in the LATS program.
Pipe Bends
When bending soft copper, use long radius bends. Refer to the “Radii of Coiled Expansion Loops and Developed Lengths of Expansion
Offsets” table on the previous page for minimum radius specifications.
Proper system operation depends on the installer using utmost care while assembling the piping system. The following pages are an over-
view of best practices when installing the refrigerant piping system.
LG Electronics U.S.A.,Inc., is not responsible for any piping calculations, refrigerant leaks, degradation of performance, any other potential problems
or damages caused by the interconnecting piping, their joint connections, isolation valves, or introduced debris inside the piping system.

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 length of the horizontal
section of pipe above or below the obstacle be a minimum of three
(3) times the longest vertical rise (or fall) at either end of the
segment.

Pipe Supports
A properly installed pipe system must be adequately supported to avoid pipe sagging. Sagging pipes become oil traps that lead to equipment
malfunction.
Pipe supports must never touch the pipe wall; supports must be installed outside (around) the primary pipe insulation jacket. Insulate
the pipe first because pipe supports must be installed outside (around) the primary pipe insulation jacket. Clevis hangers must be used with
shields between the hangers and insulation. Field provided pipe supports must 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 sagging during the life of the system. As necessary, place
supports closer for segments where potential sagging could occur. Maximum spacing of pipe supports must meet local codes. If local codes
do not specify pipe support spacing, pipe must be supported:
• Maximum of five (5) feet on center for straight segments of pipe up to 3/4 inches outside diameter size.
• Maximum of six (6) feet on center for pipe up to one (1) inch outside diameter size.
• Maximum of eight (8) feet on center for pipe up to two (2) inches outside diameter size.
Wherever the pipe changes direction, place a hanger within twelve (12) inches on one side and within twelve (12) to nineteen (19) inches of
the bend on the other side.
Support piping at indoor unit(s) as shown.
Figure 42: Pipe Hanger Details.
Use a 4" + long sheet curved sheet metal saddles between hanger bracket and insulation to promote linear expansion/contraction.

Pipe Sleeves at Penetrations
LG recommends that all pipe penetrations through walls, floors, and pipes buried underground be properly insulated and routed through an
appropriate wall sleeve of sufficient size to prevent compression of refrigerant pipe insulation and free movement of the pipe within the
sleeve. Use 4”+ curved sheet metal saddles between the bottom surface of the pipe and the bottom surface of the penetration.
Figure 45: Pipe Sleeve Options.
Diameter of penetrations must be determined by pipe diameter plus the thickness of the insulation.

Assigning the Thermistor for Temperature Detection
Each indoor unit includes a return air thermistor assigned to sense the temperature. If a wired controller is installed, there is a choice of
sensing temperature with either the indoor unit return air thermistor or the thermistor in the wired controller. It is also an option to set both
thermistors to sense temperature so that indoor unit bases its operation on the first thermistor to reach the designated temperature differen-
tial. For applicable indoor units, an optional Remote Temperature Sensor can be used in lieu of the return air thermistor—either alone or in
conjunction with a wired controller thermistor as previously described.
Wired Controller Placement
Wired controllers include a sensor to detect room temperature. To
maintain comfort levels in the conditioned space, the wired control-
ler must be installed in a location away from direct sunlight, high
humidity, and where it could be directly exposed to cold air. Control-
ler must be installed four (4) to five (5) feet above the floor where its
LED display can be read easily, in an area with good air circulation,
and where it can detect an average room temperature.
Do not install the wired controller near or in:
• Drafts or dead spots behind doors and in corners.
• Hot or cold air from ducts.
• Radiant heat from the sun or appliances.
• Concealed pipes and chimneys.
• An area where temperatures are uncontrolled, such as an outside
wall.
