Compressor and Capacitor
The Zoneline compressor is a rotary type that
operates on 265/230/208 VAC. After the
compressor has cycled off, it will not attempt to
restart for 3
minutes
+
/-10 seconds, regardless of
the state of the thermostat. This will allow internal
pressure to equalize and prevent the compressor
from stalling by trying to start against high
pressure in the sealed system.
Current flow into the compressor is monitored by
the main board to determine if the compressor is
running or locked. If the run signal is sent and a
locked condition is detected for 4 seconds, the run
signal will stop and a 3-minute count will begin.
After the 3-minute count, the run signal is sent
again. If the compressor starts, the count is reset
and the unit functions normally. If the compressor
does not start after 4 consecutive attempts, the
control will determine that a compressor failure
has occurred and a beeping alarm will sound. The
alarm will continue until the compressor failure
condition is reset by turning the unit off at the ON/
OFF switch or by removing power to the unit.
The compressor overload is internal to the
compressor for 18000 BTU models and is located
under the relay/overload cover for 9000 and 12000
BTU models. Should the overload trip (open) it will
open the common line to the compressor,
stopping compressor operation.
A copper process tube is provided for access to
the low-pressure side of the refrigeration system.
The compressor capacitor is located under the
electronics cover, above the driver board.
Filter/Dryer
The filter/dryer for heat pump models is located in
the horizontal section of the discharge tube
between the compressor and reversing valve.
The filter dryer for electric resistance heat models
is located in the liquid tube between the condenser
and the capillaries.
