Heat Insulation - Friedrich MR24DY3JMA Manuel D'installation

Installation
CAUTION: 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 248°F(120°C)].
2. Precautions in high humidity circum-
stance:
If it is operated for a long time in high
humid atmosphere [dew point tempera-
ture: more than 73.4°F(23°C)], 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 20mm.
• Stick glass wool on all air conditioners that are located in ceiling atmosphere.
