WATER HEATER
Water temperature is sensed by thermobulb inserted into the water tank. Temperature is controlled
by a mechanical thermostat.
The setpoint temperature is adjustable by turning the thermostat shaft.
Excessive temperature will trip the hi-limit safety switch, disabling the heating element. The hi-limit
will automatically reset when the dispenser cools.
WATER LEVEL
Water level is controlled by an electronic controller. The water level probe senses chassis ground
through the water. When the water level is below the probe no ground is sensed. The controller
opens the fill solenoid until the water level makes contact with the probe.
DISPENSING
Heated water flows from the tank to the dispense nozzle through an electrically controlled solenoid.
Both the safety switch and the dispense push-button must be pressed at the same time in order to
activate the dispense solenoid.
