Normal Operation

You may hear a pinging noise caused by water being picked up and thrown against the
condenser on rainy days or when the humidity is high. This design feature helps remove
moisture and improve cooling efficiency.
Water will collect in the base pan during high humidity or on rainy days. The water may
overflow and drip from the outdoor side of the unit.
The fan may continue to operate when the compressor has cycled off.

Check the house fuse/circuit breaker box
and replace the fuse or reset the breaker.
If power failure occurs, switch off and
disconnect /unplug the power cord. When
power is restored, reconnect (plug in) the
power cord, switch on the power and 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.
Clean the filter at least every 2 weeks.
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 or hot air returns.
Set the air conditioner's vent to the closed
position.
See Air Conditioner Freezing Up below.
Set the fan at MED or HIGH until the
ice melts.
