NOTE  
Setting the control at the coldest extreme of the temperature range will not cool the room any  
faster. Usually the midpoint is a good starting position. If the room temperature is not satisfactory  
after a reasonable period of time, adjust the temperature control to a lower or higher setting.  
The Thermostat automatically starts and stops cooling operation in  
order to keep the room temperature at a proper level, and this results in  
efficient use of power and economical cooling.  
Turn clockwise for a cooler room temperature.  
Turn counter-clockwise for a warmer room temperature.

GENERAL INFORMATION  
CHANGING AIR FLOW DIRECTION  
Air flow deflectors divert air from center flow to left or right and up or down.  
Adjust deflectors for desired air flow pattern.  
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.  
11  
CARE AND MAINTENANCE  
CAUTION  
To avoid death or personal injury due to electrical shock, turn fan control OFF and unplug power cord  
before cleaning or performing maintenance. After cleaning or performing maintenance, reconnect power.  
AIR FILTER  
Clean the air filter, which removes dust inside the room.  
It should be washed at least once every week during operation.  
1. Remove the Air Filter from the front grill by pulling up.  
2. Clean Air Filter with a vacuum cleaner or lukewarm, soapy  
water.  
3. Shake it when clean to remove moisture completely. Reinstall.  
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.  
3. If using concentrated liquid detergent, dilute in warm water first.  
4. Front grill may be wiped off with a cloth dampened in a mild  
detergent solution.  
5. Cabinet may be washed with mild soap or detergent and lukewarm water, then polished with liquid wax for  
appliances.  
6. Condenser and Evaporator coils should be cleaned at the beginning of each cooling season. Use a soft  
brush or vacuum cleaner to clean them, making sure that the Condenser and Evaporator coils are not  
damaged.  
7. Do not use abrasive cleaners. These items scrach, crack and discolor surfaces.  
NOTE  
To assure continued peak efficiency, condenser coils (weather side of unit) should be checked  
periodically and cleaned if clogged with soot or dirt from the atmosphere.
