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 the dispenser on a sturdy counter or shelf able to support at least 230 lbs. (104.3 kg). The
JDF-4 is designed for indoor use only.
Set the dispenser on the counter where it will be used. The JDF-4 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 JDF-4. 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 dispenser has an attached cord set and requires a 2-wire, grounded, individual branch circuit rated 120 volts
ac, 15 amp, single phase, 60Hz. The mating connector must be a NEMA5-15R. (Refer to the dataplate 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. Connect the dispenser to the power source.
4. 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 Fill
.

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 regulator in
the line when pressure is greater than 100 psi (690 kPa) to reduce it to 50 psi (345 kPa). The main water inlet is
a 3/8” (9.52 mm) barb connection.
Additionally, the dispenser’s rinse connection may be connected to a HOT WATER system.
Caution:
MAXIMUM RINSE WATER TEMPERATURE: 170 degrees F (76.6 degrees C)
Use BUNN-O-MATIC tubing, part number 32759.10_ _ (see Illustrated Parts Catalog for complete part number)
for hot water connection.
The rinse water operating pressure must be between 20 and 100 psi (138 and 690 kPa). 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 (690
kPa) to reduce it to 50 psi (345 kPa). The rinse water inlet is a 3/8” (9.52 mm) barb connection.
NOTE- At least 18 inches (457 mm) 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 pur-
chased direct from BUNN-O-MATIC (part number 32759.10_ _ [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.
Note- A water strainer (Bunn-O-Matic part number 23720.1000) should be installed in line, prior to the
flexible water line. This strainer is supplied loose with the dispenser. (See Fig. 1 for proper locations)
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 HOOKUP
CAUTION: The dispenser must be disconnected
from the power source throughout the plumbing
hookup.
RINSE WATER
All plumbing connections are located behind
the dispenser’s splash panel. Water lines may
enter the dispenser through the access holes in
either the bottom panel or the rear panel of the
dispenser.
To access plumbing connections: remove the
drip tray assembly; remove the two screws securing the splash panel to the dispenser; lower
