As directed in the International Plumbing Code of the
International Code Council and the Food Code
Manual of the Food and Drug Administration (FDA),

backflow prevention to comply with federal, state
and local codes. For models installed outside the
U.S.A., you must comply with the applicable Plumb-
ing /Sanitation Code for your area.

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 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 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 near the main control board 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 plumbing has
been hooked up, the dispenser is ready for Initial Fill.
CE REQUIREMENTS
• This appliance must be installed in locations where it can be overseen by trained personnel.
• For proper operation, this appliance must be installed where the temperature is between 5°C to 35°C.
• Appliance shall not be tilted more than 10° for safe operation.
• An electrician must provide electrical service as specified in conformance with all local and national codes.
• This appliance must not be cleaned by water jet.
• This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabili-
ties, or lack of experience and knowledge, unless they have been given instructions concerning use of this appliance by
a person responsible for its safety.
• Children should be supervised to ensure they do not play with the appliance.
If the power cord is ever damaged, it must be replaced by the manufacturer or authorized service personnel with a special
cord available from the manufacturer or its authorized service personnel in order to avoid a hazard.
• Machine must not be immersed for cleaning.
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.

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. Replace the drip tray.
2. Connect the water source to the back of the dispenser.
3. Pull the fill tube from the dispenser, remove the plug and connect it to the dispense nozzle.
4. Set the Program Switch (near main control board) to the ON position. (On older models without program
switch, set the Dispense Lockout Switch to the OFF position)
5. Connect dispenser to the power source. Press and hold the dispense button for the dispense station that the
tube is connected to for 10 seconds, until you hear the water valve turn on. (For Portion Control machines,
press and hold the PLUS/STOP switch)
6. Monitor the water bath fill level until water starts to trickle from the overflow tube. Then press the dispense
button again to stop the fill process.
NOTE: The fill timer may time out before filling is complete. Press and hold the dispense button for 10 seconds
to start again if needed.
FIG 1 Plumbing Connections - JDF-2S
PLUMBING HOOKUP
The plumbing connection is located on the rear of the dispenser. A 3/8" (9.52 mm) male flare adapter fitting
is supplied, installed on the rear of the dispenser.
NOTE - Water pipe connections and fixtures directly connected to a potable water supply shall be sized, installed
and maintained in accordance with federal, state and local codes.

7. Turn ON the refrigeration switch near the main control board. This will start the water bath pump circulation.
8. Check water level in the overflow tube and top off the tank if necessary (Step 5).
9. Disconnect the fill tube and allow excess water to drain into the drip tray. Replace the plug in the end of the
fill tube and store back into the dispenser.
10. Set the Program Switch (near main control board) to the OFF position. (On older models without program
switch, set the Dispense Lockout Switch to the ON position)
11. Replace the splash panel and drip tray.
12. It will take several hours 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 Loading,
Priming and Adjustment.

LOADING
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 33699.0002) 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 dispenser.
3. Attach the other end of the product hose to the product container through an appropriate fitting.
