Do not cover the air outlet of the outdoor unit;
If there are objects stacked around the outdoor unit, its height should be
at least 400 mm lower than the top of the unit;
When installed in a small room, certain measures should be taken to
prevent the leakage of refrigerant. Once leakage volume exceeds the
limit concentration, it may cause suffocation.

The base of the unit should be located above winter snow
level to allow proper drainage of condensate. The condensate
should be provided a path to drain before refreezing in an area
that could create an obstruction or hazardous conditions such as
on a walkway.
