HEAT INSULATION

1. Use the heat insulation material for the refrigerant piping which has an excellent heat-resistance
(over 248°F).

2. Precautions in high humidity circumstance:

This air conditioner has been tested according to the
"ISO 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 tempera-
ture: more than 73°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... EPDM
(Ethylene Propylene Diene Methylene)-over 248°F
the heat-resistance temperature.
• Add the insulation over 10mm thickness at high humidity environment.
