INSTALLATION AND START UP PROCEDURE
1. Remove dispenser and related parts from the corrugated shipping carton.
2. Locate dispenser at point of operation.
3. Connect the building’s electrical supply to the dispenser’s main power box (see wiring diagram).
4. It is recommended that the unit’s drain be permanently plumbed to the building drain and conform
to all plumbing codes and regulations.
5. Remove the dispenser’s top cover by removing two screws found on the top surface of cover.
6. Remove the filler cap found on the refrigeration platform. Pour clean cool water through the filler
hole until water is seen flowing from the overflow tube which is connected to the building’s plumbing
system. Replace filler cap and top cover.
7. Now start the refrigeration system by plugging the system’s main power cord into the outlet
provided in the cabinet’s main electrical box.
8. It is normal to see a small amount of water being displaced from the water bath through the
overflow tube as the ice bank is built.
9. A generalized fluid/gas diagram is provided at the end of this manual.
10. Position the CO2 gas tank in a secure location. Assemble high pressure regulator to CO2 gas
cylinder and run jumper line to low pressure regulator.
11. Position the syrup tanks or bag-in-box components in the desired location. Attach the CO2 gas
lines leading from the low pressure regulator to these tanks, or B.I.B. manifold.
12. Connect syrup lines from tanks or bag-in-box system to the appropriate inlets at the front of the unit.
The syrup outlet lines from the cooling unit to the dispensing tower(s) are now connected using
(normally .265” I.D.) insulated polytubing conduit.
13. The low pressure gas regulator which controls the flow of syrup to each dispensing valve is
normally set at 25 psig to 35 psig (1.75 to 2.45 bar) or as required for proper operation of the valve.
For diet type syrup, the tank pressures should be set at from 3 to 8 psi (.21 to .56 bar) or as
recommended by the syrup supplier. Additional pressure may be necessary depending on the
distance from the syrup tank to the unit.
14. Mount the water filter assembly (if used) and water regulator in a convenient location.
15. Connect water inlet line to water regulator, set at 30 to 40 psig (2.1 to 2.8 bar), to water filter, and
then to the 3/8” (9.5mm) barbed water inlet of the UCC-40.
16. Connect a (.265” I.D.) (6.7mm I.D.) CO2 gas line from the high pressure CO2 regulator to the 1/4”
(6.4mm) barbed “CO2 Supply Connection” fitting at the UCC-40. This fitting supplies CO2 gas to
the built-in carbonator tank. The normal setting range of the high pressure CO2 gas regulator is 55
to 80 psi (3.85 to 5.6 bar), but may be set as high as 100 psi (7 bar).
17. The soda water outlet fitting of the UCC-40 (a pump with tag) is connected to the dispensing
tower(s) using the 3/8” I.D. (9.5mm I.D.) line of an insulated polytubing conduit.
18. The recirculating (return) soda water from the dispensing tower(s) is connected to the 3/8” (9.5mm)
barb fitting (tag) of the UCC-40 using a 3/8” I.D. (9.5mm) line of an insulated polytubing conduit.
19. After all connections to water, CO2 gas, electrical power and syrup containers are made, check for
leaks.
20. Be sure syrup tanks or BIB boxes contain syrup.
21. Turn on water. Open the pressure relief valve on the carbonator tank by lifting the wire ring, and
hold it open until water flows from the relief valve. Close the relief valve and turn on the CO2 gas
and electrical power in that order. DO NOT operate carbonator pump with water supply shut off.
22. To fill all lines with carbonated water, cycle the carbonator several times by operating the
dispensing valves. If valves do not operate check that the valve switch it “ON”.
23. The recirculating soda water “pump/motor” is controlled by the rocker switch at the unit’s electrical
box identified as “RECIRC. PUMP SWITCH”. This switch is now turned “ON”.
24. The dispensing valves should be adjusted in accordance to the instructions of the dispensing tower
or valve manufacturer.
