GE AQV06 用户手册

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 is not on.
