Water System Operation:
The water system consists of a float valve,
reservoir and water dispense solenoid valve. The
water level in the reservoir tank is the same level
as that inside the evaporator. Building water supply
flows to both the float valve and the solenoid. The
float valve will open to add water to the reservoir
as water flows out to the evaporator. The solenoid
will only open if the water switch is closed and the
touch free sensor initiates an ice dispense.
Inside the evaporator there is a water seal. This
seal is the type that has a rotating half and a
stationary half. The area where the two seals
touch are smooth flat surfaces. When the auger is
installed in the evaporator, it forces the rotating
half of the seal against the stationary half. The
stationary half is spring-loaded and provides a firm
pressure against the auger portion of the seal.
