8. RANGE OF USAGE & LIMITATIONS
Operating temperature range
See next page.
When used below -5˚C, install a snow hood (prepared on site).
Recommendable area to install
Considering to get sufficient heating capacity, the area where the averaged lowest ambient
air temperature in day time during winter is above 0˚C, and it has no accumulation of snow.
Installation site
The limitations of installation space are shown in the page for exterior dimensions.
Install the indoor unit at least 2.5m higher than the floor surface.

Note 1. Do not install the unit in places which :
1) Flammable gas may leak.
2) Carbon fiber, metal particles, powder, etc. are floating.
3) Cosmetic or special sprays are used frequently.
4) Exposed to oil splashes or steam (e.g. kitchen and machine plant).
5) Exposed to sea breeze (e.g. coastal area) or calcium chloride (e.g. snow melting agent).
6) Exposed to ammonia substance (e.g. organic fertilizer).
7) Matters affecting devices, such as sulfuric gas, chlorine gas, acid, alkali, etc. may generate or accumulate.
8) Chimney smoke is hanging.
9) Sucking the exhaust gas from heat exchanger.
10) Adjacent to equipment generating electromagnetic waves or high frequency waves.
11) There is light beams that affect the receiving device of indoor unit in case of the wireless specification.

14) On mobile machine (e.g. vehicle, ship, etc.)
15) Splashed with water to indoor unit (e.g. laundry room).
Note 2. If ambient temperature and humidity exceed the above conditions, add polyurethane foam insulation on the outer plate (10mm or thicker) of
indoor unit.
Note 3. Both gas and liquid pipes need to be coverd with 20mm or thicker heat insulation materials at the place where relative humidity exceeds
70%.
