Remove the Cabinet Drain

6. Attach the Cabinet Drain

1) After front grille is removed, remove two screws located in both side of chassis.

2) Grip the handle of base pan and pull out the unit from chassis.

3) The air conditioner employs a proper drain method whereby the condensed water (moisture removed from the air) is drained to the outside. In very humid weather, excessive condensate water removed from the air may cause some water to collect. To remove this excess water you can install the cabinet drain as detailed below.

1 Install the cabinet drain to the left corner of the cabinet with 3 screws. 2 Connect 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. (Drain hose is not supplied)

• 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.

• CHANGING AIR FLO W 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 FLO W AR OUND 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.
