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 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 cir-
cuit. 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.
The grille is designed to clean the filter both upward and downward.
A. BEFORE ATTACHING THE FRONT GRILLE TO THE CAB-
INET, IF YOU WANT TO PULL OUT THE FILTER UPWARD;
1. Open the inlet grille slightly (a).
2. Turn inside out the front grille (a).
3. Disassemble the inlet grille from the front grille with separating the
hinged part by inserting a straight type screw-driver tip (b).
4. Then, rotate the inlet grille 180 degrees and insert the hooks into
bottom holes of the front grille.
5. Insert the filter and attach the front grille to the cabinet.
B. IF YOU WANT TO PULL OUT THE FILTER DOWNWARD;
THE GRILLE IS ALREADY DESIGNED FOR THAT WAY.
