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 regula-

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

location experiences pressure ﬂuctuations greater than 20 psi (138kPa). The main water inlet is a 3/8” (9.52

mm) MFL 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 34325.10_ _ (see Illustrated Parts Catalog for complete part num-

ber) 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 1/4” (6.35 mm) MFL connection.

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). The

JDF-2 is designed for indoor use only.

Set the dispenser on the counter where it will be used. The JDF-2 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-2. 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. (Refer to the data

plate for exact electrical requirements.)

The 230V rated dispensers have an attached cord that requires an attachment plug cap rated at least 10a,

230V. The attachment plug cap must meet with applicable national/local electrical codes.

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 plumb-

ing has been hooked up, the dispenser is ready for Initial Fill.

38310 062205

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.

Note- A water strainer (Bunn-O-Matic part number 23720.1000) should be installed in line, prior to the ﬂex-

ible water line. This strainer is supplied loose with the dispenser. (See Fig. 2 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). For models installed outside the U.S.A., you must comply with

the applicable Plumbing/Sanitation Code for your area.

INITIAL FILL

CAUTION: The dispenser must be disconnected from the power source throughout the initial ﬁll except when

speciﬁed in the instructions.

1. Remove drip tray assembly and splash panel from the dispenser.

2. Pull the overﬂow tube from its retaining clip and connect it to the main water source (black gasket is supplied

in install kit).

3. Connect dispenser to the power source.

4. Slowly open the water shut off valve and ﬁll the water bath until water trickles from the overﬂow. The dispenser

will beep for three seconds when bath is approaching full. Reduce the ﬂow rate at this time.

5. After 3 minutes of power, slowly add more water to the tank until water trickles from overﬂow again.

6. Once water bath is ﬁlled, remove water source, cap dispenser ﬁll line, and store the ﬁll tube in it’s holder (the

ﬁll tube can now be used as a sight glass).

7. Replace the splash panel and drip tray.

8. Place refrigeration switch to the “ON” position. It will take approximately three hours at 75° F (24° C) ambient

to create the ice bank required for full dispenser performance. During this time, some further trickling from

the water bath is expected due to expansion caused by ice bank formation. While the refrigeration system is

creating the ice bank, the dispenser may be readied for use as described in Plumbing, Loading, Priming and

Adjustment.

Frozen Concentrates

1. Thaw the frozen concentrate in a refrigerated 35-40 degrees F (1.6-4.4 degrees C) environment for 36 to 48

hours before use.

2. Thoroughly mix the thawed concentrate by vigorously shaking the product container.

3. Open the dispenser door.

4. Prior to placing the product container in the dispenser, make sure that the o-ring on the container adapter is

lubricated. This will ease removal of the container when it becomes necessary.

5. Place the product container in the desired position and press it ﬁrmly into the bottle adapter opening.

6. Open the vent hole in the product container.

Note: Concentrate in the container must be completely thawed and be within the temperature range of 35-40

degrees F (1.6-4.4 degrees C.) Product outside of this temperature range, especially below, will produce an

“out of brix” drink.

Ambient Concentrates (Optional)

1. Install an Ambient Concentrate Conversion Kit (BUNN-O-MATIC part number 33699.0001) per the instruc-

tions provided in the kit.

2. Attach the concentrate product hose to the appropriate concentrate line located at the rear of the dispens-

er.

3. Attach the other end of the product hose to the product container through an appropriate ﬁtting.

PRIMING

1. Open the dispenser door

2. Load concentrate per instructions in section titled Loading.

3. Close the dispenser door. NOTE: The dispenser will not operate with the door open.

4. Place a large container under the appropriate dispense nozzle.

5. Dispensers with Press and Hold Feature:

Press and hold the “Product Dispense Switch” Fig 4, until concentrate dispenses from the dispense

nozzle.

Dispensers with Portion Control Feature:

Press and hold the “+/STOP Switch” Fig 5, until concentrate dispenses from the dispense nozzle.

Note: This may take several seconds, depending on the installation and programmed pump speed.

FIG 2 Plumbing Connections

PLUMBING HOOKUP

All plumbing connections are located on the rear of the dispenser. For Models prior to the Water Inlet Valve,

both the rinse and potable water line must be connected to a water source.
