Installation
CAUTION: Install certainly the decorative panel.
Cool air leakage causes sweating. ⇨ Water drops fall.
Good example
Fit the insulator (this part) and
be careful for cool air leakage
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.
