HEAT INSULATION
1. Use the heat insulation material for the refrigerant piping which has an excellent heat-
resistance [over 120°C(248°F)].
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(73.4°F)],
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 glass wool with thickness 10(0.4) to 20
mm(0.8 inch).
• Stick glass wool on all air conditioners that are located in ceiling atmosphere.
