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.
