drain hose should not be curved,
neither screwed. The curved or screwed
hose may cause a leakage of water.
HEAT INSULATION
1. Use the heat insulation material for the refrigerant piping which has an excellent heat-
resistance (over 120°C).
2. 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 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 thickness material.
