Drain test
The air conditioner uses a drain pump to drain
water.
Use the following procedure to test the drain
pump operation:
- Connect the main drain pipe to the exterior
and leave it provisionally until the test comes
to an end.
- Feed water to the flexible drain hose and
check the piping for leakage.
- Be sure to check the drain pump for normal
operating and noise when electrical wiring is
complete.
- When the test is complete, connect the
flexible drain hose to the drain port on the
indoor unit.

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 according
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 temperature:
more than 23°C), water drops are liable to fall.
In this case, add heat insulation material
according to the following procedure:
- Heat insulation material to be prepared...
Adiabatic EPDM or NBR with thickness 10 to
20mm.
- Stick glass wool on all air conditioners that are
located in ceiling atmosphere.
