manual abstract
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-2S. 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 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 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. 38945 061506 DOOR COVER INSTALLATION 1. Install door cover by first plugging the door harness connector into the machine harness connector located at the bottom of the machine door. 2. Install door cover. 3. Secure the door cover using 5 screws provided. P3577 P3578 P3579 38945 031406 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. FIG 1 Plumbing Connections P3580-1 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. Place the Dispense Lockout switch in 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. 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. 7. Turn ON the refrigeration switch at the back of the dispenser. 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. Place the Dispense Lockout switch back to the ON position. 11. Replace the splash panel and drip tray. 12. 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 Loading, Priming and Adjust...
