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 CONTROL
setting. The brew valve discharged through the BREW HEAD:
• A portion of water is fed to the BYPASS through a reducing “tee”.
The amount of bypass water is PRESET @ approx. .27oz per
second. Bypass water flows through the brew basket, but
is diverted from the grounds by a bypass channel.
• The remainder of the water is discharged through the BREW HEAD
and flows over the grounds in the brew basket at a PRESET of
approx. .50 oz per second.
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 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.
