INDOOR UNIT INSTALLATION

PRIOR TO INSTALLATION

Before installing the indoor unit, refer to the label

on the product box to make sure that the model

number of the indoor unit matches the model

number of the outdoor unit.

Step 1: Select installation location

Before installing the indoor unit, you must

choose an appropriate location. The following are

standards that will help you choose an appropriate

location for the unit.

Proper installation locations meet the following

standards:

• 

• Convenient drainage

Noise from the unit will not disturb other

people

• Firm and solid—the location will not vibrate

• Strong enough to support the weight of the unit

• A location at least one meter from all other

electrical devices (e.g., TV, radio, computer)

DO NOT install unit in the following locations:

• Near any source of heat, steam, or combustible

gas

While choosing a location, be aware that you

should leave ample room for a wall hole (see

Drill wall hole for connective piping step) for the

signal cable and refrigerant piping that connect

the indoor and outdoor units. The default position

for all piping is the right side of the indoor unit

(while facing the unit). However, the unit can

accommodate piping to both the left and right.

Note: If the wall is made of brick, concrete, or

similar material, drill 0.2in-diameter holes in the

wall and insert the sleeve anchors provided. Then

secure the mounting plate to the wall by tightening

the screws directly into the clip anchors.

Installation

Step 3: Drill wall hole for connective piping

1. Determine the location of the wall hole based

on the position of the mounting plate. Refer to

the Mounting Plate Dimensions.

2. Use a 2.5 inches or 3.54 inches (depending on

models ) core drill to drill a hole in the wall.

Make sure that the hole is drilled at a slight

downward angle, so that the outdoor end of

the hole is lower than the indoor end by about

0.2 to 0.275 inches. This will ensure proper

water drainage.

3. Place the

Step 4: Prepare the refrigerant piping

The refrigerant piping is inside an insulating sleeve

attached to the back of the unit. You must prepare

the piping before passing it through the hole in the

wall.

1. Based on the position of the wall hole relative

to the mounting plate, choose the side from

which the piping will exit the unit.

2. If the wall hole is behind the unit, keep the

knock-out panel in place. If the wall hole is

to the side of the indoor unit, remove the

plastic knock-out panel from that side of the

unit. This will create a slot through which your

piping can exit the unit. Use needle nose pliers

will join the indoor and outdoor units. Refer to

the Refrigerant Piping Connection section of

this manual for detailed instructions.

CAUTION

Be extremely careful not to dent or damage the

piping while bending them away from the unit.

Any dents in the piping will affect the unit’s

performance.

Step 5: Connect the drain hose

By default, the drain hose is attached to the left-

hand side of unit (when you’re facing the back

of the unit). However, it can also be attached to

the right-hand side. To ensure proper drainage,

attach the drain hose on the same side that your

refrigerant piping exits the unit. Attach drain hose

extension (purchased separately) to the end of

drain hose.

hose to the underside of the refrigerant pipes.

3. Use insulation tape to wrap the signal wire,

refrigerant pipes, and drain hose tightly

together. Double-check that all items are

bundled.

Installation

DO NOT WRAP ENDS OF PIPING

When wrapping the bundle, keep the ends of the

piping unwrapped. You need to access them to

test for leaks at the end of the installation process

(refer to Electrical Checks and Leak Checks section

of this manual).

Step 8: Mount indoor unit

If you install new connective piping to the outdoor

unit, take the following steps:

1. If you have already passed the refrigerant

piping through the hole in the wall, proceed to

below Step 4.

2. Otherwise, double-check that the ends of the

refrigerant pipes are sealed to prevent dirt or

foreign materials from entering the pipes.

3. Slowly pass the wrapped bundle of refrigerant

pipes, drain hose, and signal wire through the

hole in the wall.

4. Hook the top of the indoor unit on the upper

hook of the mounting plate.

3. Connect drain hose and refrigerant piping

(refer to Refrigerant Piping Connection section

of this manual for instructions).

4. Keep pipe connection point exposed to

perform the leak test (refer to Electrical

Checks and Leak Checks section of this

manual).

5. After the leak test, wrap the connection point

with insulation tape.

6. Remove the bracket or wedge that is propping

up the unit.

7. Using even pressure, push down on the

bottom half of the unit. Keep pushing down

until the unit snaps onto the hooks along the

bottom of the mounting plate.

UNIT IS ADJUSTABLE

Keep in mind that the hooks on the mounting

plate are smaller than the holes on the back of

the unit. If you don’t have ample room to connect

embedded pipes to the indoor unit, the unit can be

adjusted left or right by about 1.25-1.95in depending

on the model.

Preparations and Precautions

Air and foreign matter in the refrigerant circuit

can cause abnormal rises in pressure, which can

and cause injury. Use a vacuum pump and manifold

gauge to evacuate the refrigerant circuit, removing

any incondensable gas and moisture from the

system. Evacuation should be performed upon

initial installation and when unit is relocated.

Before Performing Evacuation

• Check to make sure the connective pipes

between the indoor and outdoor units are

connected properly .

• Check to make sure all wiring is connected

properly.

Evacuation Instructions

1. Connect the charge hose of the manifold

gauge to the service port on the outdoor unit’s

low pressure valve.

2. Connect another charge hose from the

manifold gauge to the vacuum pump.

3. Open the Low Pressure side of the manifold

gauge. Keep the High Pressure side closed.

4. Turn on the vacuum pump to evacuate the

system.

5. Run the vacuum for at least 15 minutes, or

7. Wait for 5 minutes, then check that there has

been no change in system pressure.

8. If there is a change in system pressure, refer

to Gas Leak Check section for information on

how to check for leaks. If there is no change

in system pressure, unscrew the cap from the

packed valve (high pressure valve).

9. Insert hexagonal wrench into the packed valve

(high pressure valve) and open the valve by

12. Using hexagonal wrench, fully open both the

high pressure and low pressure valves.

13. Tighten valve caps on all three valves (service

port, high pressure, low pressure) by hand. You

may tighten it further using a torque wrench if

needed.

OPEN VALVE STEMS GENTLY

When opening valve stems, turn the hexagonal

wrench until it hits against the stopper. Do not try

to force the valve to open further.

Air Evacuation

Note on Adding Refrigerant

Some systems require additional charging depending on pipe lengths. The standard pipe length varies

according to local regulations. For example, in North America, the standard pipe length is 25ft. In other

areas, the standard pipe length is 16ft. The refrigerant should be charged from the service port on the

outdoor unit’s low pressure valve. The additional refrigerant to be charged can be calculated using the

2. Gas Leak Checks

There are two different methods to check for gas leaks.

• Soap and Water Method

Using a soft brush, apply soapy water or liquid detergent to all pipe connection points on the indoor unit

and outdoor unit. The presence of bubbles indicates a leak.

• Leak Detector Method

If using leak detector, refer to the device’s operation manual for proper usage instructions.

The indoor unit emits

white mist

In humid regions, a large temperature difference between the room’s air and

the conditioned air can cause white mist.

Both the indoor and

outdoor units emit

white mist

When the unit restarts in HEAT mode after defrosting, white mist may be

emitted due to moisture generated from the defrosting process.

The indoor unit makes

noises

A rushing air sound may occur when the louver resets its position.

A squeaking sound may occur after running the unit in HEAT mode due to

expansion and contraction of the unit’s plastic parts.

Both the indoor unit

and outdoor unit make

noises
