Features and Installation
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 avoid leaking 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.
NOTE: All supporting parts should be secured to firm wood, masonry, or metal.
