Description
The Barista Series Urn is digitally controlled brewing system. This list of features will help you understand the controls available to
you in your brewing process.
1. Each liner has three independent batch volumes.
• Each batch volume is independent
• Each batch can be programmed with pulse brewing feature
2. This urn displays coffee level inside each liner on the vertical LED graph located on the control panel under each liner. The LED
graph reports the coffee level in 1/8th of total brewed volume.
3. Each liner has coffee-hold, countdown timer.
4. Spray arms are fitted with a sensor that allows the control to know the spray arm position.
5. The main display shows the time of day and if the UP arrow is pressed once, it displays the jacket temperature for 5 seconds
and then reverts back to time of day.
6. The control system has an energy saving features that allow the urn to turn off the heat function during long periods of
non-usage. Each week day can be individually programmed to have an ON time and an OFF time. i.e., if the coffee shop opens
for business at 6 am, the urn can be programmed to heat up at 5 am so that it’s ready to brew by 5:30 am. If the coffee shop
closes at 7 pm the urn can be programmed to turn off the heat at 7 pm.
7. The urn has an automatic air agitation feature. Air agitation is used to keep the un-dissolved solids in the coffee in suspension.
The operator can program the on and off time intervals.
8. The urn is equipped with an audio alarm. It will sound 2 beeps; 2 seconds on 2 seconds off, at the end of the brew cycle –
notifying user that brewed coffee is ready to be served. And it will sound continuously for 5 minutes at the end of the coffee hold
time. The main control is equipped with an ALARM OFF button.
9. The urn has Low Temp No Brew function. If enabled, the urn will not brew unless the water temperature is within 5ºF of set point.
If enabled and one tries to start a brew before reaching the minimum brew temperature the display will flash “COLD” for
3 seconds and the alarm will sound 3 beeps; 1 second on, 1 second off.
10. Program mode is password protected. The default password is: “1208”

Installation
WARNING! ELECTRIC SHOCK HAZARD
INSTALLATION OF THIS URN SHOULD BE PERFORMED BY QUALIFIED SERVICE PERSONNEL ONLY.
IMPROPER INSTALLATION COULD CAUSE ELECTRIC SHOCK.
See rough in drawing for this model for dimensions and location of electrical and water input.
Positioning
1. Position urn so that the faucets drip into a drip trough or drain receptacle of some type.
2. Level urn both front to back and left to right. The feet are adjustable for this purpose.
IMPORTANT:
THE PERSON INSTALLING THIS COFFEE URN IS RESPONSIBLE FOR ENSURING THAT THE
ELECTRIC AND WATER CONNECTIONS MEET THE REQUIREMENTS OF THE NATIONAL ELECTRIC
CODE, THE NATIONAL PLUMBING CODE, AND ANY LOCAL ORDINANCES.
DO NOT RUN TUBING, PIPES, CONDUIT OR CABLE UNDER CENTER PORTION OF BARISTA SERIES
URNS. THIS AREA MUST BE KEPT CLEAR FOR SERVICING URN CONTROLS.
Water
1. Cold or hot water (160 degrees F. maximum) may be used. Heat input capacity is ample for the coldest water, and
cold water should be used for best brewing results.
2. Provide shut-off valve and union in supply line near urn.
3. Minimum operating pressure at urn should be 30 PSI.
4. Maximum pressure recommended at urn is 70 PSI.
5. Copper tubing should be used for flexibility.
6. To insure pressure at the urn of at least 30 PSI, use 3/8" OD tubing for short runs, 1/2" OD tubing for longer runs,
and larger size tubing for unusually long runs. Be sure other appliances will not reduce water pressure excessively.
7. Turn on the water supply line and check for leaks.
NOTE: For the best tasting coffee, add a filtering system to the water supply line to eliminate any taste and/or odor from the water.
Grindmaster® Barista Series Urns Manual Page 5
Heat Input
Electric Heated Urns, Models with suffix (E):
1. Check rating marking on urn nameplate to be sure electric lines match voltage, phase, and amperage requirements of urn.
Select the proper cord and cord grip for electrical rating of the urn. The cord must be an oil resistant type such as SO, SOO,
STO, STOO, SEO, SJO, SJOO, SJTO, SJTOO, SJEO, HSO, HSOO, HSJO, or HSJOO. Alternatively, flexible metal conduit and
type THHN wires may be used.
2. The terminal block and ground screw are located behind a cover plate on the front.
3. A neutral wire is normally required on all single phase and on 208 Volt, 3 phase power supplies to operate 120 VAC control
circuit. In the case of single phase, 2 wire service (no neutral), or 3 phase 3 wire service (no neutral), a separate 120 VAC cord
and plug (NEMA 5-15P) supplies 120 VAC power to the control circuit (or for use of transformer on heat exchange urns). This
cord must be ordered separately.
Installation (cont.)
WARNING! ELECTRIC SHOCK HAZARD
NEVER USE THE GROUND CONDUCTOR AS A NEUTRAL. THIS COULD CAUSE ELECTROCUTION.
4. A fused disconnect switch should be installed near urn.
5. Urn body MUST be grounded. A grounding terminal is provided for this purpose.
6. Use only copper wire to connect this urn.
Operation and Start-Up
1. Open water supply line valve to urn.
2. Turn on or plug in the power supply to the urn. Water compartment will begin to fill automatically. Do not power up the urn when
the water line is off.
3. Pump urns have a fast fill feature. This applies to Triple urns and models with a suffix (P) To fill the urn in only ten minutes on
these models:
The fast fill valve is located on the underneath, rear of the urn. There knurled knob that sticks out past the control drawer.
Turn valve to the right to close. Turn valve to the left to open. During initial fill the valve should be open. Close valve after
initial fill so that the valve will be closed during normal urn operation.
4. For heat exchange urns, just turn on the water. The urn will begin to fill and then heat. It will take approximately 45 minutes to
heat water, depending on inlet water temperature, and urn heater wattage.
5. Brew and discard at least one batch of water into each liner. Check that the level is correct. See the adjustments section if
changes are needed.

How to Brew in an Automatic Urn
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. Filter paper sizes are:
Liner size
Filter size Grindmaster Part #
1.5 gallon 14 x 6 BB2.0WP
3 gallon 18 x 6 BB3WP
2. Replace cover. Lift and rotate the spray arm to position the nozzle in the hole on the basket cover.
3. Press the batch size desired on the liner that the spray arm is set to brew in.
• The timer display for the batch will flash “S” or “M” or “L”; depending on which batch size button was pressed.
• To stop the brew at any time, press any of the three batch buttons for that liner.
• If the spray arm is not pointed to the same liner in which the batch button is pressed, the display will show “ARM”.
You will need to move the spray arm to the correct position, or press the batch size on the liner that the spray arm is
set to brew in.
• If after pressing a batch size, the display momentarily shows “COLD”, it means the water is not hot enough to brew. Wait
for a few minutes and try again. To check the water tank temperature press the UP arrow button once and the tank
temperature will display for 5 seconds.
4. The brew cycle takes from 1 to 6 minutes depending on the batch size. When the brew is finished, allow one to four minutes for
the coffee to drip from the basket. Drip time is dependent on the amount of coffee grounds used.
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.
