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.

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 humidity exceeds 70%.
