Insert the plastic elbows into the new pump tubing and secure it with the clamps. 16. Gently wrap the new pump tubing around the pump’s rotor. 17. Reassemble the pump housing onto the platform assembly. 18. Repeat steps 10 through 17 for the remaining pump(s). 19. Replace the dispense platform(s) into the refrigerated cabinet, making sure to reconnect all electrical and water connections. 20. Replace the dispense platform cover. 21. Turn power on to dispenser. 22 Install containers of rinse water, run each station and check for leaks. Repair leaks as necessary. 23. Replace product shelf and product containers. Reconnect any connections to ambient product containers. 24. Prime the pumps as described in “PRIMING” in the Initial Fill Section. 39690.0000 Tube Kit JDF-2S & JDF-4S 39688.0000 Tube Assembly 39992 042007 ADJUSTMENT & OPTIONAL SETTINGS Water Flow Testing and Adjustment 1. Place a graduated measuring cup or the large chamber of the empty brixing cup (BUNN-O-MATIC part number 33095.0000) under the appropriate dispense nozzle. Place the Dispense Lockout switch in the OFF position. 2. Press and release the desired “Product Dispense Switch” three times. (On Portion Control models, use the plus/stop switches) 3. The selected position will dispense water (no concentrate) only for 3 seconds. 4. Measure the water dispensed. 5. Adjust the water flow rate Fig 16, (clockwise to increase flow rate; counterclockwise to decrease flow rate) to the corresponding product mix ratio as follows: 6. Repeat steps 1 through 5 as necessary until the correct water flow rate is achieved. 7. Repeat steps 1 through 5 for the remaining dispense positions. 8. Place the Dispense Lockout switch back into the ON position. Pump Speed Adjustment 1. Disconnect the dispenser from the power source. 2. Remove the drip tray. 3. Remove the two screws securing the splash panel and remove the splash panel 4. Locate the adjustment knobs on the circuit board. 5. Turn the adjustment knobs clockwise to increase speed and counterclockwise to decrease speed. 6. The knob positions directly correspond to dispense station locations. NOTE: Some 2S models have 4 adjustment knobs on the circuit board. For these models use the two left most knobs to make pump speed adjustments. Left most being station #1 (left side dispense) and left center being station #2 (right side dispense). 7. Reinstall the splash panel and drip tray and reconnect the dispenser to the power source. P3586 FIG 16 Adjusting Water Flow Using 1/4" allen wrench Mix Ratio Adjust water flow rate to: Product Brix % (water + concentrate) 2+1 *3.75 fl. oz (111 ml) Prune Juice 16.0% per 3-second test Other * Orange Juice 11.8% 4+1 Pineapple Juice 12.8% Cranberry Fruit Cocktail 14.0% *4.0 fl. oz (118 ml) Grapefruit Juice 10.6% per 3-second test Lemonade 5+1 Apple Juice 12.0% Fruit Punch Grape Juice 13.0% 3+1 through 7+1 Other * Above 7+1 *4.0 fl. oz (118 ml) Other * per 3-second test High Viscosity Juice 2.25 - 3.0 fl. oz (66.5 - 89 ml) As Required - per 3-second test *Maximum flow rate may be less depending on the water pressure supply at each location. Note: Information for specific products listed in this table is to be used for reference only. Consult the product label for exact mix ratio and/or brix %. See product label for target brix %. 39992 023009 ADJUSTMENT & OPTIONAL SETTINGS (cont) Total Dispense Ratio Set Up Procedure 1. Adjust water flow as described in Water Flow Testing and Adjustment. Record water output setting for later reference on each dispense head. 2. Place the Dispense Lockout switch in the OFF position. 3. Place a measuring container under the dispense nozzle, press and release the DISPENSE button 6 times. 4. Record the total ounces dispensed. 5. Refer to the Brix/Ratio chart below to confirm proper total dispensed amount for ratio desired and water output previously recorded. 6. To increase or decrease the product output, refer to Pump Speed Adjustment section. 7. Place the Dispense Lockout switch back into the ON position.
