Filling System
The ll system maintains the level of water in the brewer’s tank. Anytime water is drawn off of the tank during a brew
cycle or from the hot water outlet, the ll circuit activates to rell the tank.
The ll system consists of:
• 120VAC Solenoid Inlet Valve
• Flow Control
• Fill Probe
Water enters the rear of the brewer from the supply line and rst
goes through a plastic strainer mounted in the combination inlet so-
lenoid/dilution solenoid assembly. From the solenoid valve the water
ows through a .75 gallon per minute ow control washer and then
into the bottom of the water tank.
The 120VAC solenoid inlet valve is activated by the control board
anytime the brewer calls for water. The valve opens and allows
water to ow, under line pressure, to the tank where the silicon tube
connects to a ll tube attached to the tank.
The control board monitors the level of water in the tank through a
low voltage level probe mounted to the top of the tank. The control
board grounds a 2.5VAC signal to the tank through the water. If it
looses this signal, the control board will activate the inlet valve.
