3. INSTALLATION
3.1 HOW TO INSTALL THE UNIT
1. To avoid vibration and noise, make sure 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 20" 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 1/2" or 1/4 bubble
with level).
6. Install the unit with its bottom portion 30~60" 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 hole in the rear side
if you need to drain (consult a dealer).
Plastic hose or equivalent may be connected to the drain
tube.
3.2 WINDOW REQUIREMENTS
NOTE: All supporting parts should be secured to firm wood,
masonry, or metal.
