ELECTRICAL REQUIREMENTS
CAUTION - The dispenser must be disconnected from the power source until specified in
Initial Set-Up.
This dispenser requires 2-wire, grounded service rated 208 or 240 volts ac, 40 amp, single phase.
Refer to the dispensers dataplate for exact voltage requirement.)
(
Electrical Hook-Up
CAUTION – Improper electrical installation will damage electronic components.
1. An electrician must provide electrical service as specified.
2. Using a voltmeter, check the voltage and color coding of each conductor at
the electrical source.
L2 RED
3. Remove the side panel.
4. Install the proper electrical wiring to the terminal block.
5. Connect the dispenser to the power source and verify the voltage at the termi-
L1 BLACK
nal block before proceeding. Reinstall the side panel.
6. If plumbing is to be hooked-up later be sure the dispenser is disconnected
from the power source. If Plumbing has been hooked-up, the dispenser is ready for
Initial Set-Up
.
PLUMBING REQUIREMENTS
208 or 240V.A.C.
This dispenser must be connected to a COLD WATER system with operating pressure between 20 and 90 psi (138 and 620 kPa) from a 1⁄2" or larger supply line. A shut-off valve should be installed in the line before the dispenser. Install a regulator in the line when pressure is greater than 90 psi (620 kPa) to reduce it to 50 psi (345 kPa). The water inlet fitting is 1⁄4" flare.
NOTE - Bunn-O-Matic recommends 1⁄4" copper tubing for installations of less than 25 feet and 3/8" for more than 25 feet from the 1⁄2" water supply line. At least 18 inches of an FDA approved flexible beverage tubing, such as reinforced braided polyethylene or silicone, before the dispenser will facilitate movement to clean the countertop. It can be purchased direct from Bunn-O-Matic (P.N. 00326-0000). Bunn-O-Matic does not recommend the use of a saddle valve to install the dispenser. The size and shape of the hole made in the supply line by this type of device may restrict water flow.
This equipment must be installed to comply with the Basic Plumbing Code of the Building
Officials and Code Administrators International, Inc. (BOCA) and the Food Service Sanitation
Manual of the Food and Drug Administration (FDA).
Plumbing Hook-Up
1. Flush the water line and securely attach it to the flare fitting at the rear of the dispenser.
2. Turn on the water supply.

INITIAL SET-UP
CAUTION - The dispenser must be disconnected from the power source throughout the initial set-up, except
when specified in the instructions.
1. Connect the dispenser to the power source and turn on the water supply.
2. The HEATER LED will glow for approximately five seconds. During this time, the electronic circuitry will check for a full tank of water.
3. If the tank is not full of water, the refill circuit will energize, indicated by the “REFILL” LED glowing. Water will automatically flow into the tank to the proper level and then shut off.
4. When the tank is full of water, the heater circuit will energize, indicated by the “HEATER” LED glowing intermittently until the proper temperature is achieved. A completely cold tank will take approximately twenty minutes for the water to heat.
5. The READY LED will glow when the proper water temperature is achieved.
NOTE - Stop dispensing if the READY LED is off. Dispense only when the READY LED glows.
DRAINING THE DISPENSER
CAUTION - The dispenser must be disconnected from the power source throughout these steps.
1. Disconnect the dispenser from the power source.
2. Shut-off and disconnect the incoming water supply
3. Remove the small screws from the sides and front of the top panel.
4. Gently remove one of the grommets from the tank lid.
5. Insert a tube to the bottom of the tank and syphon ALL of the water out.
NOTE - The dispenser must be refilled using the INITIAL SET-UP steps before reconnecting to the power source.
CLEANING
The use of a damp cloth rinsed in any mild, non-abrasive, liquid detergent is recommended for cleaning all
surfaces on Bunn-O-Matic equipment.

TROUBLESHOOTING
A troubleshooting guide is provided to suggest probable causes and remedies for the most likely problems encountered. If the problem remains after exhausting the troubleshooting steps, contact the Bunn-O-Matic Technical Service Department.
Inspection, testing, and repair of electrical equipment should be performed only by qualified service person-
nel.
All electronic components have 200-240 volt ac and low voltage dc potential on their terminals. Shorting of
terminals or the application of external voltages may result in board failure.
Intermittent operation of electronic circuit boards is unlikely. Board failure will normally be permanent. If an
intermittent condition is encountered, the cause will likely be a switch contact or a loose connection at a
terminal or crimp.
Solenoid removal requires interrupting the water supply to the valve. Damage may result if solenoids are
energized for more than ten minutes without a supply of water.
The use of two wrenches is recommended whenever plumbing fittings are tightened or loosened. This will
help to avoid twists and kinks in the tubing.
Make certain that all plumbing connections are sealed and electrical connections tight and isolated.
This dispenser is heated at all times. Keep away from combustibles.
WARNING
Exercise extreme caution when servicing electrical equipment.
Disconnect the dispenser from the power source when servicing, except when electrical tests are speci-
fied.
Follow recommended service procedures.
Replace all protective shields or safety notices.
PROBLEM
Equipment will not operate.
PROBABLE CAUSE
1. No power or incorrect voltage
REMEDY
(A) Check the terminal block for the correct voltage. It should be 200 to 240 volts ac across the red and black terminals for 200 to 240 volt mod­els.
(B) Check circuit breakers or fuses.
2. Overflow protection switch
Refer to tion switch for testing procedures.
