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.

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.
