SERVICING INSTRUCTIONS - ELECTRICAL
FUNCTION
1.
Pressing the POWER key energizes the unit. The
POWER LED will glow whenever the unit is ON.
2. Automatic fill is accomplished via the "FILL" section of
the INLET SOLENOID (32) and a WATER LEVEL
PROBE (7). The probe senses ground through the
water in the tank. When the water level falls below the
probe and ground is no longer sensed, the
CONTROLLER (20) energizes the fill solenoid (32) until
the water level again reaches the water level probe.
3.
Pressing any VOLUME key selects that pre-programmed
volume.
4. Pressing the BREW key begins the brew cycle.
Pressing the CANCEL key at any time during the
brew cycle terminates the brew. The BREW SOLENOID
(18) and the "BYPASS" section of the INLET SOLENOID
are energized by the CONTROLLER (20) for a time
determined by the BREW TIME setting.
A second brew can be started only after the brew time
plus the DRIP OUT time has elapsed.
5. Brew water temperature is controlled via a WATER
TEMPERATURE SENSOR (3) and a HEATING
ELEMENT (15) controlled by a TRIAC (17) electronic
switch. The element is energized according to the
sensed water temperature and the BREW TEMP setting.
An over-temperature condition will trip the HI-LIMIT
THERMOSTAT (4), de-energizing the heating element.
Note: hi-limit will automatically reset once the tank has
cooled by approximately 30ºF.
6. The unit will revert to the energy-saver mode some
time after the last brew, based on AFTER HOURS TIME
setting.
