D. Switches
Two different control switches are used for operation. They are located on the right side
of the control box which becomes accessible when the front louver is removed. The
upper is the control switch, and the lower is the service switch.

1. Control Switch

This switch is used to place the machine into one of three modes: "OFF" (center
position), "ICE" (upper position), and "SERVICE" (lower position).

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", "CIRCULATE", 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.
2. 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.
1) DRAIN
This machine 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.
