Section 2 Installation
Part Number 020001552 5/11 2-19
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.
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 CO
2 supply, set regulator initially to 26 psi,
can raise incrementally to 30 psi if their is no excessive
foaming.
3. Set bag-in-box or syrup tank push pressure CO2
regulator to 35-40 psi.
Preparing Ice Bank
BUILDING AN ICE BANK
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-
of-Syrup” device, verify that it is unplugged.)
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 Out-of-Syrup device power
cord into an appropriate wall outlet at this time (if
supplied).
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.
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.

Important
Wait until a thin layer of ice has begun to form on the
evaporator before proceeding any further.
