1. Form the piping according to its routing. Avoid

bending and bending back the same piping point
more than three times. (This will result in hard-
ening the pipe.)

2. After deforming the piping, align centers of the

union fitting of the indoor unit and the piping, and
tighten them firmly with wrenches.

3. Connect pipe to the service valve or ball valve

which is located below the outdoor unit.

4. After completing the piping connection, be sure

to check if there is gas leakage in indoor and
outdoor connection.

After completing the piping connection, execute
vacuum drying for the connecting piping and the
indoor unit.
The vacuum drying must be carried out using the
service ports of both the liquid and gas side valves.

Lay the drain hose with a downward inclination
so water will drain out.

• Alway lay the drain with downward inclina-

tion (1/50 to 1/100). 
Prevent any upward flow or reverse flow in
any part.

• 5mm or thicker formed thermal insulator

shall always be provided for the drain pipe.

1. Install declination of the indoor unit is very important for the drain of the duct type air conditioner.

2. Minimum thickness of the insulation for the connecting pipe shall be 5mm.

• The unit must be horizontal or declined to the drain hose connected when finished installation.

• Upward routing not

allowed

• Drill the piping hole with 70mm dia, hole

core drill.

• Piping hole should be slightly slant to the

outdoor side.

Insulate the joint and tubes completely.

All thermal insulation must comply with local requirement.

• Insulate and tape both the gas piping and liquid piping.
