PLUMBING REQUIREMENTS
This dispenser must be connected to a COLD WATER system with operating pressure between 20 and 100
psi (0.138 and 0.690 mPa). This water source must be capable of producing a minimum flow rate of 4 fluid
ounces (88.7 milliliters) per second. A shut off valve should be installed in the line before the dispenser. Install
a regulator in the line when pressure is greater than 100 psi (0.690 mPa) to reduce it to 50 psi (0.345 mPa).
The regulator is also necessary if the water source has pressure fluxuations. The main water inlet is a 3/8” (9.52
mm) MFL connection.
NOTE- At least 18 inches (457 mm) of an FDA approved flexible beverage tubing, such as reinforced braided
polyethylene, before the dispenser will facilitate movement to clean the countertop. It can be purchased direct
from BUNN-O-MATIC (part number 34325.10_ _ [see Illustrated Parts Catalog for complete part number.])
BUNN-O-MATIC does not recommend the use of saddle valves to install the dispenser. The size and shape of the
hole(s) made in the supply line(s) by saddle valves may restrict water flow.
INITIAL SET-UP
CAUTION: The dispenser is very heavy! Use care when lifting or moving it. Use at least two people to lift or
move the dispenser. Place dispenser on a sturdy counter or shelf able to support at least 150 lbs. (68 kg). This
dispenser is designed for indoor use only.
Set the dispenser on the counter where it will be used. This dispenser requires a minimum of 4 inches (102
mm) of air clearance at the rear and 8 inches (203 mm) of air clearance above the dispenser. Minimal clearance
is required between the dispenser sides and the wall or another appliance. For optimum performance, do not let
warm air from surrounding machines blow on the dispenser. Leave some space so the dispenser can be moved
for cleaning.
ELECTRICAL REQUIREMENTS
CAUTION: The dispenser must be disconnected from the power source until specified in Electrical Hook-Up.
The 120V rated dispensers have an attached cord set and require a 2-wire, grounded, individual branch circuit
rated 120 volts ac, 15 amp, single phase, 60Hz. The mating connector must be a NEMA 5-15R.
The 220 - 230V rated dispenser has an attached cord set and requires an attachment plug cap rated at least
230 volts ac, 15 amp. The attachment plug cap must meet with applicable national/local electrical codes.
Refer to the data plate for exact electrical requirements.
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.
3. Confirm that the compressor/water bath pump switch is in the OFF position.
4. Connect the dispenser to the power source.
5. If plumbing is to be hooked up later, be sure the dispenser is disconnected from the power source. If plumb-
ing has been hooked up, the dispenser is ready for Initial Fill.
As directed in the International Plumbing Code of the International Code Council and the Food Code
Manual of the Food and Drug Administration (FDA), this equipment must be installed with adequate
backflow prevention to comply with federal, state and local codes. For models installed outside the
U.S.A., you must comply with the applicable Plumbing /Sanitation Code for your area.
