■ 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.

does not.
