You may hear a pinging or popping 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 relays click when the controls cycle on and off or are
adjusted to change the room temperature.
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 indoor fan runs continuously when the unit is operating in the
cooling mode, unless the fan switch behind the room cabinet is set
at cycle fan (up). This will cause the fan to cycle on and off with the
compressor. You may also hear a fan noise stop and start.
You may notice a few minutes delay in starting if you try to restart the
Zoneline too soon after turning it off or if you adjust the thermostat
right after the compressor has shut off. This is due to a built-in
restart protector for the compressor that causes a 3-minute delay.
The compressor shuts off before and after the defrost cycle.
Full resistance heat comes on during the defrost cycle to maintain
room comfort.
