Installation

(For Qualified Service Technicians Only)

Keys Points

Electrical:

•The electronic controls require at least 105 volts. Less than 105 volts will cause erratic behavior from the
brewer.

•The electrical drawing for the brewer is located on the inside of the upper cover.

General:

•Do not adjust the thermostat setting unless absolutely necessary. It is set at the factory for optimum
performance.

Installation Instructions

1. Review the Dimensional Drawings and the Operating Procedures for the unit you are installing. Verify that

the brewer will fit in the space intended for it. Verify that the counter or table will support 55 lbs., the weight
of the brewer and dispensers when filled.

2. The thermostat is pre-set at the factory. There is no need to turn off the heater during the installation

process. The heater is disabled by the liquid level control board until water is sensed. The heating
process will start automatically when the tank has filled with water.

3. When the brewer is in position for use, level the brewer front to back as well as side to side by adjusting the

feet.

4. Plug the power cord into a proper receptacle

5. Turn the power switch to the “on” position.

• The “ready” light will go on briefly, then go off.

• The heaters will be disabled by the L.L.C. board until water is sensed by the water level probe.

6. Fill the water tank as follows:

• Remove the pour-over tank cover.

• Place a container under the brew basket.

• Slowly pour approximately 1½ gallons of water into the top of the brewer. This will almost completely

fill the brewer’s main tank.

• Pour additional water into the top until water begins flowing out of the brew basket into the container.

• The brewer’s tank is now completely full and the water will begin heating.

• Due to the expansion of the water as the temperature rises, water will drip from the brew basket during

the heating process. Therefore, the brew basket and container should be kept in place until the water
has reached operating temperature.

The brewer will be ready for operation as soon as the ready light comes on to indicate that the water tank is
up to brewing temperature. The time required to reach brewing temperature will vary according to the electrical
configuration and the temperature of the cold water.
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 re­heating 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.

7. Review the entire operating procedures with whomever will be using the brewer. Pay particular attention to
the following areas.

• Don't remove the brew basket until it has stopped dripping.

• Make sure the dispenser is empty before brewing into it.

• Show how to close and/or secure the dispensers for transporting.

Operating Procedures

1. Turn the power switch

• The power switch will illuminate to indicate that the brewer has power.

• When the ready light

time required to gain full operating temperature will vary depending on the electrical configuration that
was ordered, and the temperature of the cold water.

2. Prepare the brew basket

• Place a paper filter in each basket to be used. Pour the appropriate amount of pre-measured, ground
coffee into the filter. The amount of coffee used will depend on your personal tastes and the
recommendation of your roaster.

• Slide the brew basket back into the rails on the brewer.

3. Prepare the dispenser.

• Ensure that the dispenser is empty. If you are using an
airpot, open the cover and remove the pump stem
before brewing.

• Place the dispenser in position under the brew basket.

4. Remove the tank cover
amount of water into the top of the brewer.

• It is normal for the ready light to go out after the start of
the brew cycle.

• The electrical configuration and the electrical power
connected to the brewer will determine how long before
the ready light comes back on for the next brew.

5. You now have a dispenser of freshly brewed coffee, ready to serve, that will taste fresh and stay hot.
ONLY a non-heated dispenser can do that.

• If you are using an airpot, insert the pump stem before closing the cover.

CAUTION:

Do not remove the brew basket immediately after the brew cycle has finished. Wait until
dripping from the bottom of the brew basket has stopped. Carefully remove the brew basket
while inspecting the inside of the basket for hot coffee that has not finished draining.

Warranty

All FETCO brewers come with a limited warranty. All warranty service must be authorized by calling FETCO
Technical Support at [phone].

Adjustments

Thermostat Adjustment:

For equipment manufactured before April 1, 2004

The brewer’s water tank temperature is factory set at 205°F (slightly lower for high altitudes, to prevent boiling).

This setting will deliver water at 195°F ± 5° to the coffee grounds.

Measure the temperature by holding a thermometer in the stream of water flowing out of the brew basket, 1/3 of

the way through the brew cycle. The temperature should be 195°F ± 5°.

If an adjustment is necessary:

• Turn the power switch off.

• Remove the four screws on the upper cover. The upper water tank is attached to the cover.

• Lift the cover and tank just enough to reach the thermostat, which

is located on the right side, under the tank.

• Turn the adjustment stem slightly counter-clockwise to increase
the temperature, and clockwise to decrease the temperature.

• Place the tank and cover in their normal positions and turn the
power switch on.

• If you decreased the temperature setting, place a container
under the brew basket and pour water into the top of the brewer
until the “ready” light goes out

• Wait for the “ready” light to come on, and measure the temperature again.

Repeat until the desired temperature is obtained.

Effective December, 2004:

A new digital thermostat and temperature probe were introduced as a direct replacement for the old style
thermostat and probe.

During normal operation, the digital readout displays the last two digits of the actual water temperature. When the
adjustment tool is turned, the readout begins flashing to indicate the set point, not the actual temperature. After the
tool is released, the readout stops flashing and displays the actual temperature again.

A red LED lights when the power to the thermostat is on. A yellow LED lights when the thermostat is calling for
heat.

To adjust, turn the adjustment tool. If no adjustment tool is present, a small flat-head screwdriver may be used. The
display will flash, indicating that the display is showing the set point, not the actual temperature.

The dots below the numbers indicate the temp range.

0 dots – less than 100° F
1 dot – between 100° and 200° F
2 dots – over 200° F

-Refill the tank by pouring water into the top of the
brewer until it begins flowing out of the sprayhead.

-With power on, and water tank full, disconnect the
green wire connected to the water level probe.
Touching this wire to the tank should cause the relay
on the control board to click. If not, replace the board.

-Check amperage draw on heater wires. 0 amps = bad
heater.

-Replace the thermostat and or thermal probe. It’s not
possible to trouble shoot the probe.
