1. Use the heat insulation material for the refriger-
ant piping which has an excellent heat-resis-
tance (over 120°C).
2. Precautions in high humidity circumstance:
This air conditioner has been tested according to
the "KS Standard Conditions with Mist" and con-
firmed that there is not any default. However, if it
is operated for a long time in high humid atmo-
sphere (dew point temperature: more than
23°C), water drops are liable to fall. In this case,
add heat insulation material according to the fol-
lowing procedure:

• 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

• 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.
