HEAT INSULATION
1. Use the heat insulation material for the refrigerant piping which has an excellent heat-resistance
(over 248℉(120℃)).
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℉(23℃)), water drops are liable to
fall. In this case, add heat insulation material accord-
ing to the following procedure:
• EPDM (Ethylene Propylene Diene Methylene), NBR
(Nitrile Butadiene Rubber) – over 248℉(120℃)
the heat-resistance temperature.
• Add the insulation over 10mm (13/32inch) thickness at high humidity environment.
