Components Energized when the Control Switch is in the SERVICE Position
When in the "SERVICE" position, the control switch supplies power
to the service switch and the machine is
in service mode.
The service switch has three positions: "DRAIN," "CIRC." and "W
ASH." See the information
below for details of each function.
DRAIN
Power is supplied to the pump and drain valve. This drains the wat
er tank.
CIRC.
Power is supplied to the pump only. This operation can be used to
circulate cleaner and
sanitizer for extended periods of time over the outside surface of
the evaporator.
WASH
Power is supplied to the pump and wash valve. This operation is
used to circulate cleaner
and sanitizer over both the inside and outside surfaces of the eva
porator.
