4. The thermostat, timer, and the water tank fill level are pre-set at the factory. There is no need to turn off
the heaters during the installation process. The heaters are disabled by the liquid level control board
circuits on the main board until water is sensed. The heating process will start automatically when the
tank has filled with water.
5. Remove the top and rear panel to inspect for leaks, loose wires, etc., and for adjustments.
6. Water connection:
•
Water inlet is a 1/4 inch male flare fitting
•
The brewer can be connected to a cold or hot water line. Cold water is preferred for best coffee
flavor, but hot water will allow for faster recovery times. Hot water should not exceed 160°F.
•
We discourage the use of softened water. Softened water will give poor brew performance in any
drip coffee system using a paper filter.
•
Install a water shut off valve near the brewer to facilitate service. If an in-line water filter is used, it
should be installed after the water shut off valve and in a position to facilitate filter replacement.
•
Flush the water supply line and filter before connecting it to the brewer.
•
Verify that the water line will provide at least 3/4 gallons per minute, and that the water pressure is
between 20 and 75 psig.
•
Use a wrench on the factory fitting when connecting the incoming water line. This will reduce stress
on the internal connections and reduce the possibility of leaks developing after the install has been
completed.
7. Power connection:
•
A fused disconnect switch or circuit breaker on the incoming power line must be conveniently
located near the brewer, and its location and markings known to the operators.
•
All brewers require neutral. Damage to the brewer may result if neutral is not present.
•
The body of the brewer must be grounded to a suitable building ground. A ground lug is provided in
the brewer on the floor of the chassis. Use suitable gauge copper wire for grounding.
•
Electrical connections must be secured in-place within the unit to meet national and local standards.
8. Turn on the incoming water supply line and inspect both inside and outside of the brewer for leaks in all
fittings and tubes.
9. Plug in brewer and turn on the incoming power
10. Turn on the brewer with the power switch.
•
Within 6 seconds, the internal tanks will begin filling until the water is sensed by the water level
probe.
•
The heaters will be disabled by the L.L.C. circuits on the main board until water is sensed by the
water probe at the top of the tank.
On initial startup, from dry tank conditions, the green "READY" will flash 45 seconds after turning unit on,
indicating a fault (low water level). Turn the power switch off and back on to reset this. Repeat one additional time
if necessary
The brewer will be ready for operation as soon as the ready light comes on to signify that the water tank is up to
temperature.
Depending on the cost of electricity in your area, very little savings may be had by turning the brewer off
between shifts. The water tank is well insulated and may actually use less electricity to keep the tank hot, than
re-heating the tank from a cold condition. Leaving the brewer in the on position will also avoid delays at the
beginning of shifts for the brewer to reach operating temperature.
11. Brew one server (water only) to confirm proper fill levels.
• The brewer is factory set to deliver 1.9 liters to the serving dispenser.
• Each ounce of coffee retains up to two ounces of water, therefore your brew level will be reduced
proportionally to the amount of coffee used.
