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 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 glass wool with thickness 10 to
20mm.
• Stick glass wool on all air conditioners that
are located in ceiling atmosphere.
Forming the piping
Form the piping by wrapping the
connecting portion of the indoor
unit with insulation material and
secure it with two kinds of vinyl
tape.
• If you want to connect an additional drain
hose, the end of the drain outlet should be
routed above the ground. Secure the drain
hose appropriately.
In cases where the outdoor unit is
installed below the indoor unit
perform the following.
1. Tape the piping, drain hose and connecting
cable from down to up.
2. Secure the tapped piping along the
exterior wall using saddle or equivalent.
Indoor unit
Seal a small opening
around the pipings
with gum type sealer.
