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.
