Drain Piping - Friedrich MD12Y3JM Manual De Instrucciones

CAUTION: Cool air leakage causes sweating/condensation.
Ensure panel is sealed properly.
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(0.4) to 20
mm(0.8 inch).
• Stick glass wool on all air conditioners that are located in ceiling atmosphere.
