Installing the indoor unit 

INSTALLATION INSTRUCTIONS

Connecting the refrigerant pipe

1) Use torque wrenches when tightening the flare nuts to prevent damage to the flare nuts and gas leaks.

2) Align the centres of both flares and tighten the flares three  or four turns by hand. Then tighten them fully with the torque 

wrenches.

3) To prevent gas leakage, apply refrigeration oil on both inner and outer surfaces of the flare. (Use refrigeration oil for R410A.)

Caution handling piping 

1) Protect the open end of the pipe from dust and moisture.

2) All pipe bends should be as gentle as possible. 

Use a pipe bender for bending.

(Bending radius should be 30 to 40mm or larger.)

Selection of copper and heat insulation materials

• When using commercial copper pipes and fittings, 

observe the following:

1) Insulation material: Polyethylene foam

Heat transfer rate: 0.041 to 0.052W/mK (0.035 to 

0.045kca/(mh°C)

The gas refrigerant pipe’s surface temperature reaches 

110°C max. Choose heat insulation materials that will 

withstand this temperature.
