D. Control and Service Switches

2 switches are used to control the operation of the icemaker. These switches are referred to as control switch and service switch. They are located on the KMS switch 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 water pump. The service switch has three positions: "DRAIN," "CIRC." and "WASH."

Note:

1.When the service switch is active (control switch in the "SERVICE" position), power is supplied to the water pump in all three positions.

2.When the control switch is in the "OFF" or "ICE" position, the service switch is de‑activated. In this state, it can be left in any position.

a)DRAIN

This icemaker utilizes a pump-out drain system. When the control switch is in the "SERVICE" position and the service switch is placed in the "DRAIN" position, power is supplied to the water pump and drain valve.

b)CIRC.

When the service switch is active and placed in the "CIRC." position, power is supplied to the water pump only. This water pump operation is used during cleaning to circulate cleaner for extended periods of time over the outside surface of the evaporator.

c)WASH

This icemaker 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 motor and wash valve. This operation is used to circulate cleaner and sanitizer over both the inside and outside of the evaporator.
