Normal Operating Sounds
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 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 case front panel is set at fan cycle (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.
During the defrost cycle, both indoor and outdoor
fans stop and the compressor will operate in the
cooling mode to remove frost from the outdoor coil.
After defrost, the unit will restart in electric heat to
quickly warm the room to the desired comfort level.
To protect the compressor and prevent short cycling,
the unit is designed to run for a minimum of 3 minutes
after the compressor starts at any thermostat setting.
