Bunn JDF-4S PLUMBING REQUIREMENTS, INITIAL SET-UP, ELECTRICAL REQUIREMENTS

PLUMBING REQUIREMENTS

This dispenser must be connected to a COLD WATER system with operating pressure between 20 and 100

psi (138 and 690 kPa). This water source must be capable of producing a minimum ﬂow rate of 3 ﬂuid ounces

(88.7 milliliters) per second. A shut off valve should be installed in the line before the dispenser. Install a regu-

lator in the line when pressure is greater than 100 psi (690 kPa) to reduce it to 50 psi (345 kPa). 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.

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). For models installed outside the U.S.A., you must comply with

the applicable Plumbing/Sanitation Code for your area.

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 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 refrigeration switch on the rear of the dispenser 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.
