Control Panel
The control panel is shipped with a protective plastic film. This film can be left on or removed. To clean, use a damp cloth and mild detergent.
Outdoor Coil
The coil on the outdoor side of the unit should be checked periodically and cleaned if clogged with dirt or soot from the atmosphere. If extremely dirty, it may need to be professionally steam cleaned.
Base Pan
In some installations, dirt or other foreign matter may be blown into the unit from the outside and settle in the base pan (the bottom of the unit). Check the base pan periodically and clean it out, if necessary.
Tips for Energy Saving
Do not
•Block the air intake and outlet of the unit. If they are obstructed, the unit will not work well, and may be damaged.
•Let direct sunlight into the room. Use sunshades, blinds or curtains. If the walls and ceiling of the room are warmed by the sun, it will take longer to cool the room.
Do
•Keep the air filter clean. (Refer to “Care and Cleaning.”)
A clogged filter will impair the performance of the unit.
•To prevent conditioned air from escaping, keep win- dows, doors and any other openings closed.
•Keep the ventilator closed for economy and maximum cooling.
Troubleshooting
PROBLEM | POSSIBLE CAUSE | |
|
| |
AIR CONDITIONER | • The power cord is not plugged in or | |
DOES NOT | circuit breaker is tripped. | |
OPERATE |
| |
|
| |
AIR CONDITIONER | • The unit is waiting for the compressor | |
“DOES NOT COOL | overload protector to reset. | |
OR HEAT AS IT | • Curtains, blinds or furniture blocking | |
SHOULD” | ||
the front of the air conditioner are | ||
| ||
| restricting the air flow. | |
| • Thermostat control may not be set | |
| high/low enough. Turn the control to a | |
| lower or higher position. (NOTE: In | |
| some installations, the thermostat | |
| control cannot be turned all the way to | |
| the highest end or lowest end. This is | |
| normal. Do not attempt to force the | |
| control beyond its stopping points.) | |
| • A dirty air filter is blocking air flow. | |
| The filter should be cleaned at least | |
| once every 2 weeks. See the instruc- | |
| tions in the cleaning section. | |
| • The room may have been very hot or | |
| very cold when the air conditioner | |
| was first turned on. Allow time for it | |
| to cool down or warm up. | |
| • The ventilation control may be set to | |
| the OPEN position, allowing outside | |
| air to enter the room. | |
|
| |
“BURNING” ODOR | • Dust on the surface of the electrical | |
AT START OF | heater can cause a “burning” odor at | |
HEATING | the beginning of the heating opera- | |
OPERATION | tion. This odor should quickly fade. | |
|
| |
OPERATING | • Relay clicks may be heard when the | |
SOUNDS | compressor or fan cycles on and off. | |
| This is normal. | |
| • The fan runs continuously when the | |
| unit is operating unless the Fan Cycle | |
| Switch under the control panel is set | |
| to CYCLE. In this case, the fan cycles | |
| on and off with the electrical heater | |
| or compressor. | |
AIR IS NOT | • The Fan Cycle Switch may be set to | |
ALWAYS COOL | Fan Cont (continuous). This causes | |
DURING COOLING | the fan to blow room air even when | |
OPERATION | the compressor is off. The continuous | |
| air flow provides better overall tem- | |
| perature control. | |
