Service Manual  25
Installation
1) Preparation of pipings
Cut the pipes and the cable
• Use the accessory piping kit or the pipes 
purchased locally.
• Measure the distance between the indoor and the
outdoor unit.
• cut the pipes a little longer than measured 
distance.
• Cut the cable 1.5m longer than the pipe length.
Remove burrs.
• Remove burrs from cut edges of pipes.
• Turn the pipe end down to avoid the metal powder
entering the pipe.
Caution:
If burrs are not removed, they may cause gas 
leakage.
Flaring the pipes.
• Insert the flare nuts, mounted on the connection
ports of both indoor and outdoor unit, onto the 
copper pipes. Some refrigerant gas may leak,
when the flare nuts are removed from the indoor
unit, as some gas is charged to prevent the inside
of the pipe from rusting.
• Fit the copper pipe end into the Bar of flare tool
about 0~0.5mm higher. (See illustaration)
• Flare the pipe ends.
Tape the flaring part to protect it from dust or 
damages.

2) Connection of pipings
Move the indoor tubing and drain hose to the hole
• Remove tubing holder and pull the tubing out of the
chassis.
Replace the tubing holder into original position 
Route the tubing and the drain hose staight 
backwards.
Insert the connecting cable into the indoor unit
through the hole.
• Do not connect the cable to the indoor unit
• Make a small loop with the cable for easy 
connection later.
Tape the tubing and the connecting cable.
Indoor unit installation.
Connecting the pipings to the indoor unit.
• Align the center of the pipings and suffciently 
tighten the flare nut with fingers.
• Finally, tighten the flare nut with troque wrench until
the wrench clicks.
When tightening the flare nut with troque wrench,
ensure the direction for tightening follows the arrow
on the wrench.
3) Pre-cautions in bending
If it is necessary to bend or stretch the tubing,
use the Spring which is attached to the tubing
instead of pipe bender.
• Please make a careful notice to make a smooth line.
• Hold the tubing with your two hands closely and then
bend or stretch it slowly not to make any crack.
• Remember that the radius (R) should not exceed 70
mm (Refer to Fig. 1).
Do not repeat the bending process to prevent the
tubing from cracking or curshing.
Keep in mind that the bending part should not be
cracked, and make the radius (R) as long as possi-
ble (Refer to Fig.2)
