power.
4. Turn the thermostat knob in front of housing to
BREW position. Pilot light on top of thermostat
bezel will illuminate. Water in urn will heat up, and
thermometer pointer will rise to high end of BREW
zone on thermometer dial. It will take
approximately 45 minutes to heat water, depending
on inlet water temperature, and urn heater
wattage. Pilot light on top of thermostat bezel will
go out when water in urn is at brew temperature.
5. Brew and discard at least one batch of water into
each liner. Check that the fill level is correct. See the
adjustments section if changes are needed.
Operation
CAUTION: HOT LIQUID HAZARD
Water used for brewing coffee is very hot. Use
caution when brewing, pouring, or transporting
coffee. Accidental spills may result in severe burns.
CAUTION: HOT LIQUID HAZARD
Coffee basket contains very hot water until the drip
is completed. Early removal of a dripping basket could
result in burns.
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

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:
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.
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.
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.
