controller.

• Slide the Cover according to the arrow direction

• Do not use rechargeable batteries such batteries differ from standard dry cells in shape, dimensions, and performance.

• Remove the batteries from the remote controller if the air conditioner is not going to be used for an extended length of time.

Insert two battaries.

GENERAL INFORMATION

• 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.

1. Remove the Air Filter from the front grille by pulling up.

2. Clean Air Filter with a vacuum cleaner or lukewarm, soapy water.

3. Shake it when clean to remove moisture completely. Replace it.

NOTE

A dirty Air Filter reduces air flow and the cooling capacity. Do not operate unit without Air Filter.

• CLEANING THE AIR CONDITIONER

1. At least once a year, remove cabinet and thoroughly clean air conditioner. Have the unit inspected by an authorized service man to ensure unit is functioning properly.

2. Wash air conditioner with lukewarm, soapy water as needed. Rinse and dry thoroghly.
