ƕ A snowy area: Install the outdoor unit on a raised platform that is higher than drifting snow.
Provide snow vents.

ƕ in a room where there is no thermostat.
ƕ where the unit is exposed to direct sunshine or direct light.
ƕ where the unit will be in close proximity to a heat source.
ƕ where hot/cold air from the outdoors, or a draft from elsewhere (such as air vents, diffusers or
grilles) can affect air circulation.

ƕ Where the air quality is of high acidity.
ƕ Where harmful gases can be generated from decomposition.
Ɣ Do not position the drain pipe for the indoor unit near any sanitary sewers where corrosive gases
may be present. If you do, toxic gases can seep into breathable air spaces and can cause respiratory

furniture, or other possessions may result. If condensate piping becomes clogged, moisture can back
up and can drip from the indoor unit. Do not install the indoor unit where such dripping can cause
moisture damage or uneven locations: Use a raised concrete pad or concrete blocks to provide a
solid, level foundation for the unit to prevent water damage and abnormal vibration.
