WATER FLOW DIAGRAM
WATER FLOW
INLET
The INLET VALVE is controlled by a signal from the CONTROL
BOARD. If the WATER LEVEL PROBE does not detect water, the
inlet solenoid is opened until water is again sensed.
BREW
The BREW VALVE is fed by gravity from the hot water tank.
The brew valve is opened for a length of time as determined by the
TIMER setting.
The brew water is discharged through the SPRAY DISK and flows
over the grounds in the brew basket.
Each half of the brewer is independently controlled.
HOT WATER FAUCET
The HOT WATER FAUCET is fed by gravity from the hot water tank.
The faucet is spring-loaded closed and manually opened.
The 9221-Series of
brewers have two
independent brewing
systems sharing a
common hot water tank.
The hot water faucet is fed
by the hot water tank, but
is otherwise independent of
the brewing systems.
NOTE:
Use of the hot water faucet
during a brew cycle will
not change the delivered
volume. However,
excessive use of the faucet
during brew may lower the
brew water temperature.
