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.

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.

upwards.
The end of the drain
hose must NOT be
placed under water.
Do NOT bend the

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.

Installing the Air conditioner
Cutting or Extending the Pipe
A 24.6ft(7.5m) pipe is supplied with the air conditioner. (Optional)
The length of the pipe can be:
◆Extended up to 98.4ft(30m)
◆Shortened as required
☛If you need a pipe longer than 24.6ft(7.5m):
◆You must extend the assembly cable.
◆You must add refrigerant to the pipes;
otherwise, the indoor unit may freeze.
1Make sure that you prepared the required tools. (pipe cutter, reamer, flaring
tool and pipe holder)
2If you want to shorten the pipe, cut it using a pipe cutter ensuring that the cut edge
remains at 90°with the side of the pipe. There are some examples of correctly and
incorrectly cut edges below.
Oblique Rough Burr
3To prevent a gas leak, remove all burrs at the cut edge of the pipe using a reamer.

Completing the Installation
Purging the Connected Pipes
The outdoor unit is loaded with sufficient R410A refrigerant for a 24.6ft(7.5m) pipe.
You should purge the air in the indoor unit and in the pipe.
If air remains in the refrigerant pipes, it affects the compressor. It may cause reduction of
cooling and heating capacity and malfunction. Refrigerant for air purging is not charged in
the outdoor unit. Use Vacuum Pump as seen in the picture.
1Connect each assembly pipe to the appropriate valve on the outdoor unit
and tighten the flare nut.
2Tighten the flare nut first with your hands, and then with a torque wrench applying
the following torque.
3Connect the charging hose of low-pressure side of manifold gauge to a gas
service port as seen in the picture.
4Open the valve of the low pressure side of manifold gauge counterclockwise.
5Purge the air in the connected pipes using vacuum pump for about 10 minutes.
- Close the valve of the low pressure side of manifold gauge clockwise.
- Make sure that pressure gauge show -0.1MPa(-76cmHg) after about
10 minutes.
This procedure is very important to avoid a gas leak.
- Turn off the vacuum pump.
- Remove the hose of the low pressure side of manifold gauge.
6Set a valve cork of liquid and gas service port to the open position.
8Check for a gas leak.
- At this time, especially check for a gas leak from the 3-way valve’s stem
nuts and from the service port cap.
7Mount the valve stem nuts and the service port cap to the valve, and
tighten them at the torque of 183kgf•cm with a torque wrench.
