Heat insulation

- Use the heat insulation material for the

refrigerant piping which has an excellent
heat-resistance (over 120°C).

- Precautions in high humidity circumstance:

This air conditioner has been tested accord-
ing to the "KS Standard Conditions with Mist"
and confirmed that there is not any default.
However, if it is operated for a long time in
high humid atmosphere (dew point tempera-
ture: more than 23°C), water drops are liable
to fall. In this case, add heat insulation mate-
rial according to the following procedure:

• Heat insulation material to be prepared...

Adiabatic EPDM or NBR with thickness 10
to 20mm.

• Stick EPDM or NBR on all air conditioners

that are located in ceiling atmosphere.

• In addition to the normal heat insulation

(thickness: more than 8mm) for refrigerant
piping (gas piping: thick piping) and drain
piping, add further 10mm to 30mm thick-
ness material.

Wiring Connection

- Open the control box cover and connect the

Remote controller cord and Indoor power
wires.

- Remove the control box cover for electrical

connection between the indoor and outdoor
unit.

- Use the cord clamper to fix the cord.
