ALPHA DIGITAL
The Alpha Digital series of automatic coffee brewers require installation to be in compliance
with all local water and electrical power codes. The Alpha is designed to brew 12 cups at a
time. The Alpha 3D, 3DL and 3DR have three warmer plates that allow up to three decanters to
be kept at serving temperature. The hot water faucet lets you draw hot water for tea, instant
soups, chocolate drinks or cup meals - even during the brew cycle.

SETUP

STEPS FOR BREWING COFFEE:
1. Place a paper filter into the brew cone. Pour ground coffee into the filter.
2. Slide the brew cone into place. When pushed in against the stop, the brew cone fits into the slide rails
and centers it under the sprayhead (see Figure 1. illustrating basic components).
3. Place a clean coffee decanter on the warmer plate.
CAUTION - Always use an empty decanter before starting a brew cycle.
4. To start brewing, push in the momentary brew switch, located on the front panel. The brew cycle will
take approximately three minutes to complete. To stop a brew cycle press the ON/OFF button.
CAUTION - Wait for hot coffee to stop dripping from brew cone before lifting decanter.
5. To stop a brew cycle press the ON/OFF button.
The Alpha coffee brewer will produce excellent results using most grades of
coffee available from your coffee distributor. Coffee suppliers can provide coffee
in convenient pre-measured envelopes.
The Alpha coffee brewer is designed for ground coffee; Freeze Dried or Liquid
coffee products will not work.
The Wilbur Curtis Company manufactures bulk coffee dispensers (Models
MCD-7 or MCD-7G) that consistently dispense ground coffee in selected
amounts.

1. Connect a ¼" copper water line from your facility to the ¼" flare water inlet fitting on the valve, behind
the machine. Water pressure going to the machine must be stable. Use a water regulator to maintain
constant pressure. This brewer works perfectly when water pressures are from 20 to 90 psi.
2. Plug the power cord into an electrical outlet rated at 20A.
3. Turn on the toggle switch behind the unit. The heating tank will start to fill. When the water reaches the
probe, the heating element will turn on automatically.
4. The heating tank will require 20 to 30 minutes to reach operating temperature (200ºF). The READY TO
BREW indicator will light at this time.
5. When water reaches operating temperature, dispense about 12 ounces of hot water through the hot
water faucet to lower the water level in the heating tank. You can also dispense only enough water to
activate the liquid level control.

TROUBLE SHOOTING
POSSIBLE CAUSE SOLUTION
Make sure the unit is receiving enough water pressure. Open
the water line. Change the filter or filter element.
Turn the brewer off. Disconnect wires from water inlet coil
terminals and connect a power cord to the terminals. Plug cord
into a 120V outlet and verify if water flows when plugged in
and stops when power is disconnected. If valve fails this test,
replace valve.
When the water level gets below the probe tip, water should
automatically refill the tank. If not, pull wire off the probe
terminal. Water should now start flowing into the tank. If not,
check the control board of the microprocessor assembly (see
step 4), or inlet valve (step 5, below).
Pull wire out of probe terminal. With a voltmeter, check voltage
at the water inlet coil terminals. This should read 110-120
volts. If no voltage is present, check control board. Make sure
the control board is energized on terminals WHT & BLK. Lack of
power to these terminals will indicate a defect within the
circuit board. Replace the microprocessor assembly.
Check for loose connections at terminals.
PROBLEM: WATER DOES NOT FLOW INTO HEATING TANK
1. Water line turned off
or water filter needs
changing
2. Water inlet valve coil
burned out
3. Grounded probe
4. Defective or burned
out control board
CODE:
5
PROBLEM: WATER IN HEATING TANK OVERFLOWING
POSSIBLE CAUSE SOLUTION
Unplug the unit and observe water level. If water continues to
flow into tank, clean or replace valve.
Pull wire off from probe terminal. Touch the metal body of the
heating tank with the end of this wire (to ground the wire). If
water stops flowing, try cleaning the probe. Probe may have to
be replaced.
The control board must be grounded. Check for loose connec-
tions at the terminals. Make sure the grounding wire is securely
fastened to the chassis.
5. Defective water inlet
valve
6. Probe limed up
7. Non-grounded or loose

TROUBLE SHOOTING, CONTINUED
PROBLEM: WATER NOT FLOWING FROM SPRAYHEAD
SOLUTION
POSSIBLE CAUSE
Remove sprayhead and clean. Clean the sprayhead fitting.
Check water level in tank. If water is not flowing into the tank,
review steps 1 thru 4, previous page.
Check the continuity between terminals WHT & BREW VLV.
When the BREW button is pressed, there should be solid conti-
nuity between these two terminals. If not, replace the mem-
brane control panel (see the instructions below).
Make sure the board is receiving 110 to 120 volts at terminals
BREW VLV and WHITE when BREW switch has been pressed.
There should be 110 to 120V going to the dump valve. If not,
then the control board is faulty.
If the control board is functioning properly (step 14), check the
dump valve. Measure voltage across the two terminals of the
valve coil. You should read 110 to 120 volts. Check also for
clogging or lime deposits. Clean if possible. Replace valve or
coil.
12. Sprayhead clogged
13. Water level is too low
in heating tank
14. Defective control board
15. Defective dump valve
or coil
CODE:
PROBLEM: WATER IN TANK DOES NOT GET HOT
OR WATER TEMPERATURE TOO LOW
POSSIBLE CAUSE SOLUTION
CODE:
Make sure unit is on; power cord plugged in. Toggle switch is
on. Breaker is on.
Remove the sensor and squeeze a dab of silicone compound
(part no. WC-5229) between the sensor and the tank body.
Make sure the fastening nut is secure. Check the wire for
damage.
Check element for continuity and or check with clamp amme-
ter. This should show a reading of approximately 15 amps
(depending on element wattage). If no power is going through
element, replace the heating element.
If checks #8, #9 and #10 are normal, the control board is not
operating correctly. Replace the microprocessor assembly (#8,
figure 6.).
8. Power is off
9. Defective or loose heat
sensor
10. Burned out heating
element
11. Defective control
board
REPLACING THE MEMBRANE CONTROL PANEL
IMPORTANT - This procedure requires careful positioning of the membrane control panel. Improper
application of the new part will ruin the membrane when you try to lift it again. You will have to acquire an
additional panel to complete the task.
TEST
Before you actually remove the old membrane, test the old one by using your new membrane. Your old
one may be okay.

REPLACE THE MEMBRANE CONTROL PANEL
1. Unplug the machine from your power source or switch off at the circuit breaker.
2. Remove the cover accessing the control board.
3. On this unit there is a hot water faucet over part of the membrane control panel that must be removed.
Open the faucet and let the hot water pour out until the flow stops.
WARNING TO HELP AVOID PERSONAL INJURY
Allow faucet to cool before proceeding. Components may be hot.
4. Disconnect the ribbon cable plug from the control board.
5. Remove the old membrane control panel by lifting one of the corners and peeling it from the front of the
unit. Pull the flex cable through the hole.
6. With acetone, remove any adhesive left on the stainless surface. Clean and dry the surface.
7. Take your new panel and insert the flex cable through the opening in front of the unit and connect the
flex cable to the control board.
8. Peel off the paper backing on the new membrane panel and carefully position the panel. Line it up
correctly with the switches and LEDs. Press onto the surface of the unit. You must get this right the
first time. Any attempt to reposition the membrane control panel will damage the small switches within
the membrane.
9. Reinstall the faucet. Turn on the water. Return the top cover and front cover. Plug the power cord into
andoutlet.
7
1. Unplug the machine from your power source.
2. Remove the cover accessing the control board.
3. Unplug the ribbon connector from the control board then take the new
membrane and plug the connector into the control board. Place it on a hard
surface outside the unit.
CAUTION Do not bend the new membrane.
When pressing the buttons always have a hard, flat, surface to push
against. The tiny dome switches within the membrane may become
inverted unless you have something solid behind it.
WARNING TO HELP AVOID PERSONAL INJURY
Do not place objects or reach your hands into the open unit.
4. Return power to the unit and press the ON/OFF button on the new membrane control panel.
5. If your unit still does not function normally, your problem may not be with the membrane panel, but in
another component. If your unit runs okay, then proceed with the replacement of the membrane
control panel.
Figure 3. Testing
Membrane, Typical
1. Slide out the brew cone and clean around the sprayhead and dome using a nontoxic cleaner.
2. Remove the sprayhead from the brewer and clean it. This should be done at least once a week, more
often in heavy lime areas.
3. Wipe any spills, dust or debris from the exterior surfaces.
4. Clean the brew cone slide rails with a brush or damp cloth.
5. The outside surfaces should be cleaned with a stainless steel polish only, to prevent scratches.
6. The inside of the heating tank may occasionally require deliming. The frequency is determined by
local water conditions.
CLEANING AND PREVENTIVE MAINTENANCE
CAUTION: Do not use cleansers, bleach liquids, powders or any other substance that contains chlorine.
These products promote corrosion and will pit the stainless steel.
THE USE OF THESE PRODUCTS WILL VOID YOUR WARRANTY.
