Start-Up
1.Turn on main water supply, set incoming regulator to 25 PSI (must be lower than CO2 supply pressure). Once water is supplied to the unit air needs to be purged from the carbonator tank. Do so by lifting press relief valve tab until water comes out of relief valve.

Regulator to 25 psi |
NOTE: Always set the water pressure to 25 psi first and only when no CO2 pressure is present. The CO2 pressure will bleed back and raise the water pressure gauge.
2.Turn on main CO2 supply, set regulator initially to 26 psi, can raise incrementally to 30 psi if their is no excessive foaming.

1.At this time, fill the unit water bath tank to the top, or within 1/2” (1.3 cm) of the top minimum, of the overflow tube. Use a garden hose or another water supply to do this.
NOTE: A manual fill valve is incorporated into the water circuit to the carbonator tank. This valve can be used to manually add water lost for any reason. Do not leave this valve ON constantly, only use it for filling and topping off. The water bath must be drained, flushed, and refilled every six months.
2.Turn ON the switch labeled “Refrigeration”. Allow unit to run for about 15 minutes before proceeding to step 3.
3.Turn ON the switch labeled “Agitator”.
Note: Turn this switch OFF to perform any operations in the water bath area.
With water bath water temperature of 65°F (18°C), ice must begin to form on the evaporator coils in approximately 2 hours. The unit will build a full ice bank in approximately 4 to 6 hours (depending on ambient water temperature).

4.Before turning on the carbonator or circulator switch, verify that the pump box assembly has been mounted and connected to the unit and the appropriate syrup and water has been supplied.
5.Turn on the main water supply to the booster assembly. Verify the booster is plugged in and that the accumulator tank valve is open. (If the system has an optional “Out-
6.Verify the pump is running. Place the valve on the right side of the pump box in the purge position until all air bubbles have passed through the line. Turn the valve back to “dispense”. Plug the
NOTE: Verify that the pump box holding tank is full before proceeding.
7.Turn on the circulator and carbonator switches. The carbonator must run for approximately 1 to 3 minutes and shut off. The circulator must run continuously. Verify that water is returning to the water bath through the return bulk head fitting.
Important
Wait until a thin layer of ice has begun to form on the evaporator before proceeding any further.
8.Go to the tower(s) and brix the valves. Using a syrup separator and volume cup, adjust the flow rate of the carbonated water to two fluid ounces per second. Then, using the separator and a brix cup, adjust the syrup flow rate for a ratio of carbonated water to syrup to 5 to 1.
