Piping insulation work
• Perform heat insulation work completely on both gas and the liquid pipe. Because improper insulation will result
condensate formation over pipe.
• Use the heat insulation material for the refrigerant piping which has an excellent heat resistance (over 120°C
(248°F)).
• Precautions in high humidity circumstance
– This air conditioner has been tested according to the "KS Conditions" and confirmed.
– If it is operated for a long time in high humid atmosphere (dew point temperature: more than 23°C(73°F)),
water drops are liable to fall. In this case, add heat insulation material according to the following procedure.
CAUTION
• Make sure to insulate any field piping all the way to the piping connection inside the unit. Any exposed piping
may cause condensation or burns if touched.
• Heat insulation material : Adiabatic glass wool with
thickness of 10~20mm(13/32 ~13/16 inch).
• Stick glass wool on all air conditioners that are located
in ceiling atmosphere.
Make sure that there is no clearance here.
