Calibrating Pump Pressure
This procedure must be done while extracting a double espresso.
During the extraction, watch the water pressure gauge and
ensure it maintains 135-140psi.
If the pressure gauge does not read 135-140psi, adjust the
adjustment screw, located on the water pump assembly, in
quarter-turn increments (clockwise to increase setting,
counterclockwise to decrease setting); the pump must be set at
135-140psi for proper brewing.
Once 135-140psi is achieved, pour a double espresso to verify
the setting.
Calibrating Espresso
If a customer-specific recipe exists, verify the recipe settings are
programmed into the machine. Make any necessary adjustments and/or
program them as necessary.
Configuring the Bean Hoppers
The Xpress defaults to dispensing regular and decaffeinated espresso
drinks. The bean hoppers only need to be configured if the machine will
not be serving regular and decaffeinated espresso drinks.
However, the Xpress can also be programmed to serve both espresso
drinks and coffee drink.
1. Place coffee beans in the rear grinder.
2. Calibrate the bean grind to customer specification.
3. Navigate to SPECIAL FEATURES > GRIND CONFIG, and then
select ESPRESSO & COFFEE.
To configure the Xpress to deliver only regular beans, navigate to
SPECIAL FEATURES > GRIND CONFIG, and then select REGULAR
ONLY.
NOTE: The REGULAR ONLY option will only draw beans from the front
hopper. To protect the rear bean grinder, leave the empty rear bean
hopper atop the machine. This will prevent debris from entering and
damaging the bean grinder and brew group.
