HEAT INSULATION
1. Use the heat insulation material for the refrigerant piping which has an excellent heat-resis-
tance [over 120°C(248°F)].
2. Precautions in high humidity circum-
stance:
This air conditioner has been tested ac-
cording to the "KS Standard Conditions
with Mist" and confirmed that there is
not any default. However, if it is oper-
ated for a long time in high humid at-
mosphere [dew point temperature: more
than 23°C(73.4°F)], water drops are li-
able to fall. In this case, add heat insula-
tion material according to the following
procedure:
• Heat insulation material to be prepared... Adiabatic glass wool with thickness 10 to 20mm.
• Stick glass wool on all air conditioners that are located in ceiling atmosphere.
