10. Installation
- Countermeasure:
• Use the carpet on the floor (compared to the tiles the
carpet over it will have a 3 degree rise in temperature)
• Insulating the floor.
• Floor heating
CAUTION
• Case of cold air intake:
The duct surface will have the dew drops so a insulation
on the duct is a must.(Insulation material: a glass wool of
thickness 1.0inch will be appropriate.)
3) In case of high temperature or high
humidity between the false ceiling and
ceiling slab(near by the sea, river, lake,
spa)
- In case of temperature of 30 degree and humidity
above 80%, the units body as well as the piping
insulation should be strengthened.
Refer to the picture given below.
Psychrometric chart
Relative humidity
- Places having the temperature and humidity of the
surrounding water sources(sea, river etc.)
In case the steam is generated between the false ceiling
and the ceiling slab
Due to some nearby by steam source.
• Indoor unit: Insulate the unit body with some insulation
like glass wool at least 13/32 inch in thickness.
Additional insulation required

• Refrigerant piping: Increase the piping insulation
thickness with thickness above 13/16 inch.
• Others: Inside the ceiling near th air tight seal places
(To escape of the humidity inside false ceiling)
Grill for ventilation
4) In case of multiple indoor cassette units
