• AIR FLOW AROUND UNIT

Check in door grill and outdoor louvers for air flow obstructions. Do not block air flow to and from unit. The outdoor

coil should be checked and periodically cleaned for debris that may collect and block unit air flow. If air flow is

obstructed or deflected back into unit, the compressor may cycle on and off rapidly, causing early compressor

failure.

• DRAIN HOLE AND WATER DRIPPING OUTSIDE

Locate drain hole at the rear or on the bottom of unit. Water in base pan is picked up by the fan blade and thrown

onto the warm outdoor coil where it evaporates. The air conditioner must be installed level or tilted slightly to the

outside for proper water disposal. On exceptionally hot and humid days the air conditioner may permit excess

water to pass thru rear drain hole or overflow. This should be considered normal.

• DOOR VENT

The door vent for the room air ventilation is lever type.

If the door vent lever moves to the left, then close the 

vent and moves to the rght, then open the vent.
