Installing and connecting the assembly pipe of the indoor unit

1. Cut out the appropriate knock-out piece (A, B, C) on the rear of the indoor

unit unless you connect the pipe directly from the rear.

2. Smooth the cut edges.

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

to each pipe. Tighten the nuts rst with your hands, and then with a

torque wrench, applying the following torque:

4. Cut o the remaining foam insulation.

5. If necessary, bend the pipe to t along the bottom of the indoor unit.

Then pull it out through the appropriate hole.

 

The pipe should not project from the rear of the indoor unit.

 

The bending radius should be 100 mm or more.

6. Pass the pipe through the hole in the wall.

Connect indoor and outdoor units with eld-supplied copper pipes by means of are connections. Use insulated seamless

refrigeration grade pipe only, (Cu DHP type according to ISO1337), degreased and deoxidized, suitable for operating pressures

of at least 4200 kPa and for burst pressure of at least 20700 kPa. Under no circumstances must sanitary type copper pipe be

used.

There are 2 refrigerant pipes of dierent diameters:

• The smaller one is for the liquid refrigerant

• The larger one is for the gas refrigerant

A short pipe is already tted to the air conditioner. You may

need to 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

Outer Diameter Torque (kgf•cm)

ø6.35 mm 140~170

ø9.52 mm 250~280

ø12.70 mm 380~420

ø15.88 mm 440~480

ø19.05 mm 990~1210

ø22.23 mm 990~1210

• If you want to shorten or extend the pipes, refer to page 32~33.

• Tighten the are nut with torque wrench according to specied method.

If the are nut is over-tightened, the are may break and cause refrigerant gas leakage.

• DO NOT WALL UP THE PIPE CONNECTION !

All refrigerant pipe connection must be easy accessible and serviceable.

• The pipe will be insulated and xed permanently into position after nishing the installation and the gas leak test .
