Precautions for connecting pipes

〉

• Avoid the connection pipes of indoor and outdoor units from getting in contact with the terminal of the

compressor.

• If installing the outdoor unit higher than the indoor unit, caulk the space around insulation and tubes

because condensation on the check valve can seep through to the indoor unit side. Adjust the height of the

insulation material on liquid pipe when it has the possibility of getting in contact with the terminal. Also

make sure that the connect

ing piping does not touch the mounting bolt of the compressor.

Precautions regarding insulation

〉

Enhance the insulating material of the refrigerant piping according to the installation conditions. If this is not

done, condensation may form on the surface of the insulation material. Please refer to the target values

shown below.

• When the temperature and humidity conditions are 30°C and RH 75% or more: thickness of the

insulation material is 15 mm or more.

insulation material is 20 mm or more.

• When the temperature and humidity conditions are 30°C and RH 80% or more: thickness of the

• Always insulate the liquid and gas-side interunit piping as well as the refrige

rant branch kit.

(Not insulating them may cause leaking.)

(The highest temperature that the gas-side piping can reach is around 120°C, so be sure to use insulating

material which is very resistant.)

CAUTION

For local insulation, be sure to insulate all the way to the pipe connections inside the unit.

(Exposed piping may cause leaking or burns on contact.)
