Safety Precautions

You should take the following safety precautions when using your air conditioner.

WARNING

• If you don’t follow the safety precautions, you may get the risk of an

electric shock, injury or death. • The manufacturer or qualified service

personnel must install this air conditioner. • Unplug the electric power

before repairing, installing or cleaning.

◆Users should not install the air conditioner by themselves.

Ask the dealer or authorized company to install the air conditioner

except the window-type air conditioner in U.S.A and Canada.

◆If you don’t install the air conditioner properly, it may cause a fire,

a water leakage or an electric shock.

◆Install the indoor unit higher than 8.2ft(2.5m) from the floor to avoid the

injury caused by the operation of the fan.

(except the window-type air conditioner)

◆The manufacturer is not responsible for the accidents or injury caused

by an incorrect installation.

◆When installing the built-in type air conditioner, keep all electric cables

such as the power cable and the connection cord in pipes, ducts, or

cable channels to protect them from the danger of impact or any other

incidents.

INSTALLING THE

AIR CONDITIONER

◆If the power cord of the air conditioner is damaged, it must be replaced by

the manufacturer or a qualified person in order to avoid a hazard.

◆The air conditioner must be plugged into an independent circuit if

applicable or connect the power cable to the auxiliary circuit breaker.

An all pole disconnection from the power supply must be

incorporated in the fixed wiring with a contact opening of 0.118inch(3mm).

◆Do not extend an electric cord to the air conditioner.

◆You must install the air conditioner according to the national wiring

regulations and safety regulations.

determine the position of the inch(65mm)hole through which the cable,

pipe and hose pass to connect the indoor unit to the outdoor unit.

When facing the wall, the pipe and cable can be connected from the:

On delivery, there may be inert gas inside the indoor unit.

You should purge the gas from the indoor unit before connecting the assembly pipe.

1Determine the position of the pipe and drain hose hole as seen in the

picture and drill the hole with an inner diameter of inch(65mm) so that it slants

slightly downwards.

2 If you fix the indoor unit to a... Follow Steps...

Wall 3.

Window frame 4to 6.

3Fix the installation plate to the wall giving attention to the weight of the indoor unit.

➢If you mount the plate on the concrete wall with anchor bolts,

the anchor bolts must not be projected by more than inch(20mm).

4Determine the positions of the wooden uprights to be attached to the window frame.

5Attach the wooden uprights to the window frame giving attention to the weight of the

indoor unit.

Installing and Connecting the Drain Hose of the Indoor Unit

Installing and Connecting the Drain Hose of the Outdoor Unit

To install the drain hose, do the following.

1If necessary, connect the 6.56ft(2m) extension drain hose to the drain hose.

2If you use the extension drain hose, insulate the inside of the extension drain hose

with a shield.

3Fit the drain hose into 1 of 2 drain hose holes, and then fix the end of the

drain hose with a clamp tightly.

➢

If you don’t use the other drain hose hole, block it with a rubber stopper.

4Pass the drain hose under the refrigerant pipe keeping the drain hose tight.

➢The hose will be fixed permanently into position after finishing

the installation and the gas leak test;

refer to page 12 for further details.

While heating, ice may accumulate. During the process of defrosting,

you should check if condensate draining is adequate.

For the adequate draining, do the following.

1Insert the drain plug into the drain hole on the underside of the outdoor unit.

2Connect the drain hose to the drain plug.

3Ensure that condensate draining is adequate.

5Pass the drain hose through the hole in the wall. Check if it slants

downwards as seen in the picture.

Shield

Drain hose Extension drain hose

When installing the drain hose for the indoor unit, you should check if condensate draining is adequate.

When you pass the drain hose through the inch(65mm) hole drilled in the wall, check the following.

The hose must

NOT slant

upwards.

The end of the drain

hose must NOT be

placed under water.

Do NOT bend the

hose in different

directions.

Keep a clearance of at

least 2inch(50mm)

between the end of the

hose and the ground.

Do NOT place the

end of the drain hose

in a hollow.

Installing and Connecting the Assembly Pipe of the Indoor Unit

There are 2 refrigerant pipes of different diameters:

◆The smaller one is for the liquid refrigerant

◆The larger one is for the gas refrigerant

A short pipe is already fitted to the air conditioner. You must extend the pipe

using the assembly pipe. (Optional)

The connection procedure for the refrigerant pipe varies according to the exit

position of the pipe when facing the wall:

◆Right (A)

◆Left (B)

◆Underside (C)

◆Rear

1Cut out the appropriate knock-out piece on the rear of the indoor unit unless you con-

nect the pipe directly from the rear.

2Smooth the cut edges.

3Remove the protection caps of the pipes and connect the assembly pipe to each pipe.

Tighten the nuts first with your hands, and then with a torque wrench applying the

following torque.

Outer Diameter Torque

inch(6.35 mm) 10.1~12.3ft•lb(140~170kgf•cm)

inch(12.70 mm) 27.5~30.4ft•lb(380~420kgf•cm)

inch(15.88 mm) 31.8~34.7ft•lb(440~480kgf•cm)

➢

If you want to shorten or extend pipes, refer to page 11.

4Cut off any excess foam insulation.

5If necessary, bend the pipe round, along the bottom of the indoor unit and out through

the appropriate hole, taking care to ensure that:

◆The piping does not jut out from the rear of the indoor unit

◆The bending radius is 4inch(100mm) or more

7For further details on how to connect to the outdoor unit and purge the air,

refer to page 12.

➢The pipe will be insulated and fixed permanently into position after

finishing the installation and the gas leak test; refer to page 13 for

further details.

6Pass the piping through the hole in the wall.
