Convergence of Technological Innovation with Flexibility and Style

Single Zone Wall

Mounted Art Cool

Premier Systems

Choosing an LG Single Zone Wall Mount-

ed Art Cool Premier product provides a

system designer an edge to engineer

a system with individual control, and

design flexibility with advanced controls.

These single-zone systems are avail-

able in a nominal capacities of 3/4 to 2

tons. These are best suited for applica-

tions with zones that require heating or

cooling, such as residential, and small

business office buildings. Single Zone

Wall Mounted Art Cool Premier out-

door and indoor units are available in

208–230V/60Hz/1Ph.

Adaptable and Flexible

Single zone wall mounted split systems

allow cooling or heating for the entire

residence or just a single room without

the need for invasive ductwork. There is

minimal renovation needed.

Long refrigerant piping lengths allow

for extra design flexibility in indoor unit

installation.

These units may be used for a number of

residential or commercial environments

such as:

• Older homes

• New home construction

• Office buildings

• Restaurants

• Hospitals / Medical facilities

• Schools

• Nursing homes

• Retail establishments

• House of worship

Inverter Technology

Inverter variable-speed duct-free split

systems are measurably quieter and

consume less energy than conventional

air conditioners. The inverter compressor

ramps up or down to match the required

room capacity and maintain the comfort

level. When the selected temperature

is reached, the inverter compressor

operates at low speed to maintain that

comfort level, thereby using less energy.

PRODUCT FEATURES AND BENEFITS

Single Zone

Wall Mounted Art Cool

Premier

Single zone systems are equipped with

inverter components that offer superior

load matching and long piping installation.

The product works for optimizing power

consumption in residential and small office

buildings. Utilizing multiple indoor wall mount

units each with custom temperature controls

allow for precise temperature settings in

each zone of the building. Single zone sys-

tems allow flexibility in interior design and

complement any decor.

Low Sound Levels

When outdoor units run at full load, they

have a quiet operating sound level. To pro-

mote a quiet, comfortable environment, the

LG single zone system indoor units operate

at sound levels as low as 26 dB(A) (22 dB(A)

in sleep mode) and the outdoor units as low

as 48 dB(A) at full load. All rotating compo-

nents are soft-started by the controller using

digitally controlled inverters, which reduce

undesirable noise caused by fans and com-

pressors cycling on and off.

Comfort Control at Its

Best

Unlike traditional air conditioning control

systems, which use thermostatic controls to

maintain room temperatures, LG single zone

inverter controls continuously vary the indoor

unit fan speed and refrigerant flow.

LG single zone one-to-one systems continu-

ously measure the room temperatures and

adjust system operations accordingly to

maintain set temperature.

The outdoor unit responds by varying the

compressor speed and outdoor fan mo-

tors as needed to maintain system operat-

ing pressure. As a result, the single zone

systems deliver targeted space temperature

control.

Inverter Driven

The twin rotary compressors are optimized

to maximize compressor efficiency, which

reduces power consumption and monthly

utility bills. This latest inverter technology

allows single zone system outdoor units to

vary the compressor motor shaft speed to

deliver an appropriate amount of cooling to

the indoor unit. Precise refrigerant volume

delivery translates into long periods with coil

surface temperatures below dew point and

minimizes compressor and fan component

run time which may lead to lower utility us-

age.

Simplified Installation

Cooling and heating applications that use

single zone systems simplify and reduce the

mechanical and control system design time.

The designer no longer has to be concerned

with interconnecting chilled and condenser

water piping, air-distribution duct systems,

matching and selecting chillers, towers,

pumps, coils, fans, air handlers, or Variable

Air Volume (VAV) boxes.

Operating Range

Single zone systems have a nominal capac-

ity range of 3/4 to 2 tons (depending on

outdoor/indoor units).

Outdoor unit operating ranges for single

zone systems:

Cooling: 14°F DB to 118°F DB

Heating: -13°F WB to 65°F WB

(Installing an optional Low Ambient Wind

Baffle Kit will allow operation down to 0°F in

cooling mode for these single zone sys-

tems.)

Compact Size

Single zone outdoor units have the following

footprint:

LAU090HYV3, LAU120HYV3:

(WxHxD [in.]) 34-1/4 x 25-19/32 x 13.

LAU150HYV3, LAU180HYV3, LAU240HYV3

(WxHxD [in]) 37-13/32 x 32-3/4 x 13.

Fin Design with Gold-

Fin™ Coating

All single zone outdoor units are provided

with large surface coils made of copper

tubes with louvered aluminum fins designed

to maximize unit operating efficiency over a

wide range of ambient conditions.

Standard from the factory, every single zone

outdoor unit coil fin surface is coated with

LG’s exclusive GoldFin™ anti-corrosive

coating designed to prevent natural surface

corrosion of the aluminum fins. This main-

tains heat transfer properties of the coil for

an extended time.

A hydrophilic coating is applied to the

outdoor unit coil fin surface over the GoldFin

coating. This coating enhances the develop-

ment of heavier water droplets gathering on

the fin surface. As a result, the droplets roll

off the fin surfaces, delaying the point when

frost forms on the coil surface during heat-

ing operation. This coating also makes it

possible to easily clean the outdoor unit coil

using a mild soap.

LG Monitoring View (LGMV) Diagnostic Software and Cable

LGMV software allows the service technician or commissioning agent to connect a computer

USB port to the outdoor unit main printed circuit board (PCB) using an accessory cable with-

out the need for a separate interface device. The main screen for LGMV shall allow user to

view the following real time data on one screen:

Additional screens can be accessed by tabs on the main screen:

1. Cycleview: Graphic of internal components including:

2. Setting: Converts metric values to imperial values.

3. Making Data: Recording of real time data to a separate file created to be stored on the

user’s computer.

4. Loading Data: Recorded data from a saved “.CSV” file can be loaded to create an LGMV

session.

5. Electrical Data: The lower half of main screen is changed to show the following:

• Compressors showing actual speeds

• EEVs

• IDUs

• Low and high pressures

• Temperature and pressure sensors

• Four-way reversing valve

• Outdoor fans showing status and speeds

• Inverter compressor

- Amps

- Volts

-

Power Hz

- Inverter control board fan Hz

In lieu of connecting to the outdoor unit, user has the option to connect to the indoor unit with the use of a USB to RS-485 connector kit.

When connected through the indoor unit, user will not be able to record data.

This software can be used to both commission new systems and troubleshoot existing systems. LGMV data can be recorded to a “.CSV” file

and emailed to an LG representative to assist with diagnostic evaluations.

EQUIPMENT SELECTION PROCEDURE

Cooling/Heating Correction Factors

For Single Zone Art Cool Premier systems, calculate the equivalent length of the liquid line from the outdoor unit to the indoor unit. Also, de-

termine the elevation difference of the indoor unit above or below the outdoor unit. Find corresponding cooling or heating capacity correction

factors as shown in the table below. Multiply the correction factors by the cooling or heating capacity obtained from the capacity tables using

design conditions. The resultant is the NET cooling or heating capacity.

BUILDING VENTILATION DESIGN GUIDE

Method 1: 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 con-

ditioned space through a separate register or grille. This approach requires a separate independent ventilation duct system not associated

with single zone systems.

Advantages

• May be used with single zone systems.

• The outdoor air unit may supply “neutral” air to the occupant space

even when the single zone system indoor unit fan changes speed

or cycles on and off. DDOAS controls do not have to be interlocked

with the single zone 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.

Disadvantages

• Ceiling space is required to accommodate ductwork between the

centralized outdoor air unit and ceiling diffusers.

LG recommends using the DDOAS method in all installations.

Building Ventilation Design Guide

ASHRAE 62.1 and local codes specify the minimum volume of outdoor air that must be provided to an occupied space. Outdoor air is re-

quired to minimize adverse health effects, and it provides acceptable indoor air quality for building occupants. The three methods of accom-

plishing this with single zone systems are summarized here.

Although we believe that these building ventilation methods have been portrayed accurately, none of the methods have been tested, veried, 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, in law or in fact, including

but not limited to any implied warranty of merchantability or tness for a particular purpose.

• For a complete copy of Standard 62.1-2010, refer to the American Standard of Heating and Air Conditioning Engineers (ASHRAE)

website at www.ashrae.org.

Method 2: Unconditioned Outdoor Air (Non-Ducted, Natural Ventilation)

Natural ventilation devices, such as operable windows or louvers may be used to ventilate the building when local code permits. The open

area of a window or the free area of a louver must meet the minimum percentage of the net occupied floor area.

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 single zone systems.

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 3: 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 single zone systems.

Disadvantages

• In some locations of the country, it may be difficult to control

humidity levels while outdoor air louvers/hoods are opened.

• Thermal comfort levels may be substandard when louvers/hoods

are opened.

• 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.

This may result in loss of building pressurization control, increasing inltration loads with adverse effects.

PLACEMENT CONSIDERATIONS

Selecting the Best Location

DANGER

To avoid the possibility of re, do not install the unit in an area where combustible gas may generate, ow, stagnate, or leak. Failure to do so will

cause serious bodily injury or death.

Install a fence to prevent vermin from crawling into the unit or unauthorized individuals from accessing it. Do not install the unit in a location

where acidic solution and spray (sulfur) are often used as this may cause serious bodily injury or death. Do not use the unit in environments

where oil, steam, or sulfuric gas are present as this may cause serious bodily injury or death.

Select a location for installing the outdoor unit that will meet the following conditions:

• Where there is enough strength to bear the weight of the unit.

• Include space for drainage to ensure condensate flows properly out of the unit when it is in heating mode.

• Include enough space for air flow and for service access.

Dont's

• Where the unit will be subjected to direct thermal radiation from other heat sources.

• Where operating sound from the unit will disturb inhabitants of surrounding buildings.

• Where the unit will be exposed to direct, strong winds.

To ensure the outdoor unit operates properly, certain measures are required in locations where there is a possibility of heavy snowfall or

severe wind chill 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

system may malfunction.

3. Remove any snow that has accumulated by 4 inches or more on the top of the outdoor unit.

4. Place the outdoor unit on a raised platform at least 20 inches higher than the average annual snowfall for the area. In environments where

there is a possibility of heavy snow, the frame height must be more than two (2) times the amount of average annual snowfall, and should

not exceed the width of the outdoor unit. If the frame width is wider than the outdoor unit, snow may accumulate.

5. Install a snow protection hood.

6. To prevent snow and heavy rain from entering the outdoor unit, install the suction and discharge ducts facing away from direct winds.

7. Additionally, the following conditions should be taken into consideration when the unit operates in defrost mode:

• If the outdoor unit is installed in a highly humid environment (near an ocean, lake, etc.), ensure that the site is well-ventilated and has a lot

of natural light. (Example: Install on a rooftop.)

• Sidewalks or parking lots near the outdoor unit may accumulate moisture after unit operates in defrost mode that can turn to ice.

The indoor unit may take longer to provide heat, or heating performance will be reduced in winter if the unit is installed:

1. In a narrow, shady location.

2. Near a location that has a lot of ground moisture.

3. In a highly humid environment.

4. In an area in which condensate does not drain properly.

Ambient Air Conditions

• Avoid exposing the unit to discharge from boiler stacks, chimneys, steam relief ports, other air conditioning units, kitchen vents, plumb-

ing vents, or substances that may degrade performance or cause damage to the unit.

• When installing multiple outdoor units, avoid placing the units where discharge of one outdoor unit will blow into the inlet side of an adja-

cent unit.

Avoid exposing the unit to sources of extreme temperature or gases to prevent serious bodily injury.

General Mounting for Outdoor Units

Securely attach the outdoor unit to a condenser pad, base rails, or

another mounting platform that is securely anchored to the ground

or building structure. Attach the outdoor unit with a bolt and nut on a

concrete or rigid mount. Refer to the applicable installation manual

and follow applicable local codes for clearance, mounting, anchor

and vibration attenuation requirements.

All referenced materials are to be eld-supplied. Images are not

Mounting Platform

The underlying structure or foundation must be designed to sup-

port the weight of the unit. Avoid placing the unit in a low lying area

where water may accumulate. When installing the outdoor unit on

the wal, or roof top, anchor the mounting base securely to account

for wind, earthquake or vibration.

Tie-Downs and Wind Restraints

The strength of the Single Zone system frame is adequate to

be used with field-provided wind restraint tie-downs. The overall

tie-down configuration must be approved by a local professional

engineer.

Always refer to local code when designing a wind restraint system.

Snow and Ice Conditions

In climates that experience snow build-up, place the unit on a raised platform to ensure 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.

More than 8 inches

More than

4 inches

More than

4 inches

At least 6.5 feet from the floor

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

sidewalks or driveways which may create unsafe conditions.

CAUTION

Follow recommended best practices when choosing an indoor location for the

single zone indoor unit.

• Use a metal detector to locate studs in the walls. Anchor unit following stud

location, to prevent damage to the wall.

• Clearance gap between any wall or enclosure and the left or right side of the

unit must be greater than 4 inches.

• Minimum clearance of the indoor unit from its top to the ceiling is 8 inches.

• Unit should be at least 6.5 feet from the oor for adequate clearance.

• Keep unit away from any indoor steam or excessive heat.

• No obstacles should be placed around unit.

• Condensation drain (leakage piping) should be routed away from the unit.

• Do not install near doorway.

If the outdoor unit is installed between standard and minimum

clearances, capacity decreases approximately 10 to 20%.

Outdoor Unit Clearances

PLACEMENT CONSIDERATIONS

Minimum Clearance Requirements for Single Zone Art Cool Premier Systems

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 below.

Specific clearance requirements in the diagram below are for the Single Zone Wall Mounted Art Cool Premier systems. Figure 13 shows the

overall minimum clearances 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 in Figure 13) for height in relation to the unit. This clearance ensures that heat radiation from the condenser is not

restricted around the unit.

Adhere to all clearance requirements if installing the unit on a roof. Be sure to level the unit and ensure that the unit is adequately anchored.

Consult local codes for rooftop mounting requirements.

In order to have successful service access to the outdoor unit, see Figure 13 for minimum spacing. When installing multiple outdoor units,

see Cases 4 and 5 in Figure 13 for correct spacing requirements.

Physical Pipe Length: Actual length of straight segment(s) of pipe.

Equivalent Pipe Length: Actual length of pipe plus equivalent lengths of long radius elbows, Y-branches, and valves.

1. Draft a one-line diagram of the proposed piping system connecting outdoor unit to indoor units. Follow the pipe limitations listed on the

previous page.

2. Calculate the physical length of each pipe segment and note it on the drawing.

3. Calculate the equivalent pipe length of each pipe segment.

Using Elbows

Field-supplied elbows are allowed as long as they are long radius and designed

for use with R410A refrigerant. The designer should be cautious with the quantity

and size of fittings used, and must account for the additional pressure losses in

equivalent pipe length calculation. The equivalent pipe length of each elbow must

be added to each pipe segment. See the table for equivalent lengths.

Refrigerant Piping Design & Layout Best Practices

Field-Provided Isolation Ball Valves

LG maintains a neutral position on using isolation valves in refrigerant piping systems. LG does not endorse any manufacturer of isolation

valves. It is recognized that installing isolation valves may simplify future maintenance requirements, and, if used, considerations should 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 may 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 may be voided in whole or part should any field supplied accessory

fail in any way that causes product failure.

Refrigerant Piping System Layout

INSTALLATION & LAYOUT BEST PRACTICES

No Pipe Size Substitutions

Using a different size is prohibited and may result in a system malfunction or failure to work at all.

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 unit and the indoor unit. Single Zone Wall Mounted Art Cool Premier air-source systems

are provided with redundant systems that ensure 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 verify

the refrigerant piping system is free of traps, sagging pipes, sight glasses, filter dryers, etc.

Pipe Supports

A properly installed pipe system should be adequately supported to avoid pipe sagging. Sagging pipes become oil traps that lead to equip-

ment malfunction. 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 must 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 feet (5′) 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 as shown.

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 Sleeves at Penetrations

LG requires 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. Underground refrigerant pipe shall be routed inside a protective sleeve to prevent insulation deterioration See figure below.

Figure 26: Pipe Sleeve Options.

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.

Refrigerant

Piping

Figure 33: Refrigerant Pipe Brazing.

It is imperative to keep the piping system free of contaminants and debris such as copper burrs, slag, or carbon dust during installation.

All joints are brazed in the field. Single Zone Wall Mounted Art Cool Premier

refrigeration system components contain very small capillary tubes, small orifices,

electronic expansion valves, oil separators, and heat exchangers that can easily

become blocked. Proper system operation depends on the installer using best

practices and utmost care while assembling the piping system.

• While brazing, use a dry nitrogen purge operating at a minimum pressure of three

(3) psig and maintain a steady flow.

• Blow clean all pipe sections with dry nitrogen prior to assembly.

• Use a tubing cutter, do not use a saw to cut pipe. De-burr and clean all cuts

before assembly.

• Store pipe stock in a dry place. Keep pipe capped and clean.

• Use adapters to assemble different sizes of pipe.

• Do not use flux, soft solder, or anti-oxidant agents.

• 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, field-provided isolation ball valves, service valves, and long radius elbows shall be completely insulated using closed

cell pipe insulation. The liquid and vapor lines must be insulated separately.

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 must 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.

The design engineer should perform calculations to determine if the factory-supplied insulation jackets are sufficient to meet local codes and

avoid sweating. Add additional insulation if necessary. Mark all pipes at the point where the insulation jacket ends. Remove the jacket. Install

field-provided insulation on the run-out and main truck pipes first. Peel the adhesive glue protector slip from the insulation jacket and install

the clam-shell jacket over the fitting.

Charging

Each outdoor unit is factory charged (nameplate charge) for the

evaporator as well as a standard 25 foot line. Any time a line set is

used longer then the standard line set length, the refrigerant charge

has to be adjusted.

You must adjust the charge based on how many feet of piping are

added based on 0.22 or 0.38 oz. of R410A per foot. The factory

charge accommodates pipe lengths up to the standard length without

requiring refrigerant removal.

Example: A 50 ft line set is used --

25.4 additional feet x 0.22 oz per ft = Add 5.58 oz

of R410A

If you are uncertain of the unit charge, reclaim, evacuate and weigh in

the correct charge using the unit nameplate (capacity) charge adjust-

ing for line sets longer than 24.6 ft. This will prevent any interruptions

to the functioning of the unit and possible damage.
