5.1
WATER SUPPLY
IMPORTANT
A WATER PUMP AND WATER REGULATOR ARE INSTALLED IN THE BASE OF THE MACHINE.
A WATER FILTER SHOULD BE INSTALLED IN THE WATER LINE BEFORE BEING
CONNECTED TO THE MACHINE. FLUSH THE FILTER WITH SEVERAL GALLONS
(12-15 LITERS) OF WATER PRIOR TO USE TO INSURE BLACK CARBON "FINES" ARE NOT
FED INTO THE FREEZING CHAMBER.

CAUTION:
THE BACKFLOW PREVENTION DEVICE (FBD PN 12-2272-0001) MUST HAVE A DRAIN LINE
CONNECTED TO THE VENT (SEE FIGURE 5.1). THIS IS REQUIRED TO DRAIN AWAY WATER
IN THE EVENT OF A BACKFLOW SITUATION OR A FAILURE OF THE BACKFLOW DEVICE.
FAILURE TO DO SO MAY RESULT IN FLOODING OF THE ESTABLISHMENT.
NOTE:
Water pipe connections and fixtures directly connected to a potable water supply shall be sized,
installed, and maintained in accordance with federal, state and local codes.
A. Connect the backflow prevention assembly to the water inlet of the unit (see Figure 5.1). The
backflow prevention assembly is provided with the unit.
B. Fabricate a 3/8 inch supply line for connecting the unit to a potable water supply (a 3/8” barb by
1/4” flare nut fitting will be required).
C. Install a shutoff valve in the water line as close to the unit as practical and convenient. The use
of a water filter is recommended.
D. Clear the line by running a minimum of two (2) gallons (7.57 liters) of water through the line
before attaching the line to the unit.
E. Connect the line to the bulkhead fitting labeled "WATER IN" located at the rear of the unit (see
Figure 5.2).
F.
Do not turn water on at this time.

CO
2
SUPPLY
NOTE:
The CO
2
supply may come from either an independent tank/regulator or a bulk CO
2
system. If
connected to a bulk CO
2
system, ensure the bulk regulator is set at 115 to 120 PSIG (793.5 to
828.0 KPa)] and install a shutoff valve and a secondary supply regulator [to be set at 70-72 PSIG
(482.6-496.4 KPa)] in the line.
Ensure that the CO
2
line comes directly from the main branch
on the bulk supply and is not branched off down line. Failure to do so may starve the unit
of CO
2
flow and cause performance problems.
A. Fabricate a 3/8 inch supply line for connecting the unit to a CO
2
supply.
B. Connect the supply line to the CO
2
bulkhead fitting labeled "CO
2
IN" located at the rear of the
unit (see Figure 5.2). A 3/8” barb by 1/4” flare nut fitting will be required to make connection.
