HEAT INSULATION
- Use the heat insulation material for the refrigerant piping which has an excellent heat-resistance
(over 120 °C).
- 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), 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 EPDM or NBR with thickness 10 to 20 mm.
- Stick glass wool on all air conditioners that are located in ceiling atmosphere.
