What To Do
• Make sure the air conditioner plug is pushed completely
into the outlet.
• Check the house fuse/circuit breaker box and replace
the fuse or reset the breaker.
• If power failure occurs, turn the air conditioner OFF.
When power is restored, wait 3 minutes to restart the
air conditioner to prevent tripping of the compressor
overload.
• Make sure there are no curtains, blinds or furniture
blocking the front of the air conditioner.
• In COOL mode, press the Decrease w pad.
• Clean the filter at least every 30 days.
See the Operating Instructions section.
• When the air conditioner is first turned on, you need to
allow time for the room to cool down.
• Check for open furnace floor registers and cold air
returns.
• See "Air conditioner freezing up" below.
• Set the controls at HIGH FAN or HIGH COOL and set the
thermostat to a higher temperature.
• This is normal.
• For proper water disposal, make sure the air conditioner
slants slightly from the case front to the rear.
• This is normal for a short period in areas with little
humidity; normal for a longer period in very humid
areas.
• Check the position of the batteries. They should be
inserted in the opposite (+) and (–) direction.
• Replace the batteries.
• Unplug the air conditioner. Wait 3 minutes and plug it
back in. If the error code reappears, call for service.
