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-
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 to 20 mm.
• Stick glass wool on all air conditioners that are located in ceiling atmosphere.
