1. Place filter paper in brew basket with designated amount of coffee grounds. Coffee experts recommend from 6 to 10 ounces of coffee per gallon of water. Make certain you have a level bed of coffee. Consult your coffee supplier for exact brewing specifications. Acceptable filter paper sizes are:

Liner size Filter size Grindmaster Part #

1.5 gallon 13” x 5” ABB1.5WP

3 gallon 18” x 6”

6 gallon 21” x 9”

ABB3WP

ABB6WP

10 gallon 25” x 11” ABB810WP

2. Replace cover. Lift and rotate the spray arm to position the nozzle in the hole on the basket cover.

3. Set the batch size toggle for a full or half batch.

Press the start button on timer.

4. The brew cycle takes from 2 to 15 minutes depending on the size of the urn. When the brew is finished, allow one to two minutes for the coffee to drip from the basket.

5. When the drip period is complete, center the spray arm and remove the basket to throw away the grounds. Replace the liner cover to keep the coffee hot.

6. Coffee is ready to serve.

7. Hold brewed coffee at 185 to 190°F by turning to the HOLD setting on thermostat knob.


Adjustments

NOTICE:

Urn should be up to temperature before making adjustments of the brew system.

Brew Volume: Sprayover Time and Rate

Timer and sprayover rate are factory set. If other volumes of water or a faster or slower sprayover rate is desired, see following instructions:

Timer Adjustment

The brew timer's full batch may be adjusted. The adjustment screw is located behind the plug under the start and stop buttons. See the figure below. Since the sprayover rate is constant, the length of brew time sets the brew volume. The half batch is exactly 1/2 of the full batch.

Sprayover Rate Adjustment

Pump Urns: models starting in 72, 73, 77, 82, 83, 87,

93, CH, or suffix (P).

A fixed orifice is located in top of spray arm swivel post.

The only way to adjust the rate of flow from the spray arm is to drill a larger hole for more sprayover water or replace the existing orifice with a smaller hole size for less sprayover water.

Heat Exchange Urns: models beginning in 74, 80, 81,

84, 91, 99, without suffix (P).

Heat exchange urns have a regulator which adjusts the sprayover rate. The adjustment screw is located under urn in the back of the control drawer on the left side, or inside the control box on the Midline Urns. See

Figure A. Loosen, CCW, the screw to decrease flow and tighten, CW, the screw to increase the flow. The spray pattern should touch the weld line near the top of the liner.

To set the sprayover rate, follow these steps:

1. Divide the desired brew size by the desired brew time. This is your sprayover rate in gallons per minute.

2. Operate the brew timer for one minute and measure the amount of water. If the volume is higher than your sprayover rate from step 1, decrease the flow. Increase the flow if the volume is too low.

3. Continue the adjustment until the desired rate is achieved.

Bypass Adjustment (Refer to Figure B)

The bypass adjustment controls the amount of water which bypasses the coffee during the brew. This water dilutes the final brew. If bypass is desired, open red handle on bypass valve. This opening will bypass up to about 40% of total sprayover water. Each complete turn is approximately equal to 5% bypass.

Figure B

Thermostat Adjustment

The thermostat is factory set so that the maximum temperature is about 200° F in heat exchange urns and

195° F in pump urns. This is the high end of brew range on the thermometer and corresponds to the BREW position on the thermostat. The HOLD position is the low end of the brew range on the thermometer, or

185°F.

Water should never boil in the urn. If you need to adjust the maximum setting of the thermostat, do the following:

1. Remove the thermostat knob.

2. Insert small screwdriver into the center of the shaft.

Turn the screw slightly clockwise to decrease the temperature.

3. Check the setting by adding cold water to make sure the temperature reaches the high end of the

BREW range.
