G. Switches
Two control switches are used to control operation in KMS Series Modular Crescent
Cubers. These switches are referred to as the "control switch" and the "service switch"
and are located on the control box.
1. Control Switch
The control switch has three positions: "OFF" for power off; "ICE" for icemaking, and
"SERVICE" to activate the service switch.
2. Service Switch
When the control switch is 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 "WASH." See the information below for details of
each function.
Note:
1. When the service switch is activated, power is supplied to the water pump in all
three positions.
. When the control switch is in the "OFF" position or in the "ICE" position, the
service switch has no power and can be left in any position.
a) DRAIN
The KMS series utilizes a pump-out drain system. When the service switch is active and
placed in the "DRAIN" position, power is supplied to the pump and drain valve.
b) CIRC.
When the service switch is active and placed in the "CIRC." position, power is
supplied to the pump only. This operation can be used to circulate cleaner for extended
periods of time over the outside surface of the evaporator.
c) WASH
The KMS series utilizes a solenoid operated wash (bypass) valve. When the service
switch is active and placed in the "WASH" position, power is supplied to the pump and
wash valve. This operation is used to circulate cleaner and sanitizer over both the inside
and outside of the evaporator.
