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 efficiency.
• You may hear the thermostat click when the compressor cycles on and off.
• 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 run even when the compressor does not.

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 mode control to 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.
• Turn the knob to a higher number.
The highest setting provides maximum cooling.
• Clean the filter at least every 2 weeks.
See the care and maintenance 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.
• Set the air conditioner's vent to the closed
position.
• See Air Conditioner Freezing Up below.
• Set the mode control at High Cool with the high
temperature mark 1 or 2.
