the unit is installed securely and firmly.
2. Install the unit where the
sunlight does not
shine directly on the unit.
If the unit receives direct sunlight, build an
awning to shade the cabinet.
3. There should be no obstacle, like a fence,
within 50cm which might restrict heat
radiation from the condenser.
4. To
prevent reducing performance, install
the unit so that louvers of the cabinet are
not blocked.
5. Install the unit a little obliquely outward not
to leak the condensed water into the room
(about 10~15mmor 1/4 bubble with level).
6. Install the unit with its bottom
75-150cm above the floor level.

7. Stuff the foam between the
top of the unit
and the wall to prevent air and insects from
getting into the room.
8. The power cord must be connected to an
independent circuit. The green wire must
be grounded.
9. Connect the drain tube to the base pan
rear hole in the rear side. Drain hose or
equivalent may be connected to the drain
tube. (Drain hose is not supplied.)
When the base pan rear hole is open,
connect the drain tube.
When the base pan rear hole is capped
with hole rubber, replace with the drain
tube if you need to drain.
