2. Precautions in high humidity circumstance.
This air conditioner has been tested according to the "JIS Standard Conditions with Mist" and have been
confirmed that there are no faults. 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 20
mm.
•
Stick glass wool on all air conditioners that are
located in ceiling atmosphere.
•
In addition to the normal heat insulation
(thickness: more than 8 mm) for refrigerant
piping (gas piping: thick piping) and drain
piping, add a further of 10 mm to 30 mm
thickness material.
Wall seal
•
When the outdoor unit is installed on a higher position than the indoor unit, install the trap so as not to instill
rain water into the wall by transmitting in piping.
•
Stuff the space among piping, the electric wire, and the drain hose with "Putty" and seal the penetration wall
hole.
Make sure that rain water do not instill into the wall.
