120°C(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 23°C(73°F)), water drops are liable to
fall. In this case, add heat insulation material accord-
ing to the following procedure:
• Heat insulation material to be prepared... EPDM
