7. SWITCHES
Two different control switches are used for operation of
KMD-210AB-HC. These switches
are referred to as the "control switch" and the "service switch" and are located on the control
box.
[a] 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).
[b] SERVICE SWITCH
When the control switch is placed in the “SERVICE” position, power is supplied to the
service switch. The service switch can be used to perform two functions: draining the tank
(“DRAIN” = lower position) and washing the icemaking compartment (“WASH” or
“CIRCULATE” = upper or center position). Both the “WASH” and “CIRCULATE” positions
activate the same function of washing the icemaking compartment. The service switch is
activated in any of the three positions when the power is supplied to the pump motor.
1) “DRAIN”
KMD-210AB-HC employs the pump-out drain system. When the service switch is active and
placed in the lower position, power is supplied to the pump motor and drain valve.
2) “WASH” or “CIRCULATE”
When the service switch is active and placed in the upper or center position, power is
supplied to the pump motor. This function is to clean the evaporator plate.
