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.
• 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.

1. Wrap the connecting portion of indoor
unit with the Insulation material and
secure it with two Plastic Bands. (for the
right pipings)
• If you want to connect an additional drain
hose, the end of the drain-outlet should keep
distance from the ground. (Do not dip it into
water, and fix it on the wall to avoid swinging
in the wind.)
2. Tape the Pipings, drain hose and
Connecting Cable from bottom to top.
3. Form the pipings gathered by taping
along the exterior wall and fix it onto the
wall by saddle or equivalent.
In case of the Outdoor unit being installed
below position of the Indoor unit.
FORM THE PIPINGS
