2Connect the drain hose to the outlet located at the bottom of the cabinet drain.

You can purchase the drain hose or tubing locally to satisfy your particular needs.

OPERATING INSTRUCTIONS

•FAN & COOLING CONTROL

The Fan Control Selector Switch has six positions.

Choose one of the speed settings by rotating the fan control Selector Switch to the appropriate position.

OFF Select this setting for stop all operation of air conditioner

FAN Select this setting for low speed air circulation without

cooling and heating.

LOW COOL Select this setting for cooling operation with LOW FAN.

HIGH COOL Select this setting for cooling operation with HIGH FAN.

LOW HEAT Select this setting for Heating operation with LOW FAN.

HIGH HEAT Select this setting for Heation operation with HIGH FAN.

•TEMPERATURE CONTROL

Choose a temperature settings by rotating the knob of thermostat to the appropriate position

•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.

•HEATER LAMP

When the unit sets heating operation condition, the red lamp is lighted.

When the frost settles on the heat exchanger of the outside, defrosting is made automatically and the red

lamp is turned off.

The unit may give a hiss and the fan motor stops for 1 to 10 minutes.

This should not be regarded as a problem.

After defrosting, the heating operation begins again.

NOTE

•FOR MOST ECONOMICAL USE

1. Properly control the room temperature.

2. Avoid the unit being exposed to direct sunlight. Keep direct sunlight from the room.

3. Do not leave doors and windows open.

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.

CAUTION

When the air conditioner has been performing its cooling operation and is turned “OFF”or set to

•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.

•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.
