NOTE
• ECONOMICAL AND COMFORTABLE USE
1. Properly control the room temperature.
2. Avoid being exposed to direct sunlight.
3. Prevent the wind from entering the room.
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 terperature is not satisfactory
after a reasonable period of time, adjust the temperature control to a lower or higher.

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.
AUTO SWING When the auto louver switch is turned to “ON” position, the vertical louvers
automatically move right and left.
Thus, you can obtain comfortable cooling.
The vertical louvers may be stopped at any position when the auto louver
switch is turned off.
• 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.
• HOW TO INSTALL THE DRAIN CAP

If you want to install the drain cap, please install the drain
cap like Fig. of the drain cap.
