OPERATING INSTRUCTIONS (continued)
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 AND BYPASS
The BREW VALVE 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 valve discharged through the BREW HEAD in two
ways:
A portion of water is fed to the BYPASS through a reducing "tee".
The amount of bypass water is controlled by the opening size of the
leg of the "tee". Bypass water flows through the brew basket, but
is diverted from the grounds by a bypass channel.
The remainder of 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.
