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 0.4 inch(10 mm) to 0.8
inch(20 mm).
• Stick glass wool on all air conditioners that are located in a house attic.
