Preparation of Piping
HEAT INSULATION
1. Use the heat insulation material for the refrigerant piping which has an excellent heat-resistance (over
120°C).
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 tem-
perature: more than 23°C), 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... Adiabatic
glass wool with thickness 10 to 20mm.
• Stick glass wool on all air conditioners that are located in ceiling atmosphere.
• In addition to the normal heat insulation (thickness: more than 8mm) for refrigerant piping (gas piping: thick
piping) and drain piping, add further 10mm to 30mm thickness material.
