Select a location for the refrigeration unit that meets the
requirements of the building plans, local codes, and
personnel. The unit must be positioned for free airflow
as well as for future service. The following requirements
must be met:
• 300 GPH (1135 LTR/hr) potable water supply (all
models)
• Beverage quality CO
gas (bulk or bottled supply)
2
with a minimum 3/8” (.96 cm) line
• One Bag-In-Box (BIB) container of each post mix
syrup flavor.
NOTE: Refer to nameplate on side of refrigeration unit
for voltage and amperage specifications. Make all
electrical connections at the junction box located at the
top rear of unit. Optional equipment may require
additional power supplies.
NOTE: Potable water connections to the equipment
must comply with local plumbing code requirements,
particularly the back-flow prevention requirements.
Carbon Dioxide (CO2) displaces oxygen. Exposure
to a high concentration of CO
gas causes tremors,
2
which are followed rapidly by loss of consciousness
and suffocation. If a CO
gas leak is suspected,
2
particularly in a small area, immediately ventilate the
area before repairing the leak. CO
lines and pumps
2
must not be installed in an enclosed space. An
enclosed space can be a cooler or small room or
closet. This may include convenience stores with
glass door self serve coolers. If you suspect CO
2
may build up in an area, venting o f the BIB pumps
and/or CO
monitors must be utilized.

Electrical
GENERAL
All wiring must conform to local, state and national
codes.
MINIMUM CIRCUIT AMPACITY
The minimum circuit ampacity is used to help select the
wire size of the electrical supply. (Minimum circuit
ampacity is not the beverage/ice machine’ s running amp
load.) The wire size (or gauge) is also dependent upon
location, materials used, length of run, etc., so it must be
determined by a qualified electrician.

GROUNDING INSTRUCTIONS
When using electric appliances, basic precautions
The beverage/ice machine must be grounded in
accordance with national and local electrical codes.
This appliance must be grounded. In the event of
malfunction or breakdown, grounding provides a path of
least resistance for electric current to reduce the risk of
electric shock. This appliance is equipped with a cord
having an equipment-grounding conductor and a
grounding plug. The plug must be plugged into an
appropriate outlet that is properly inst alled and grounded
in accordance with all local codes and ordinances.
Improper connection of the equipment-grounding
conductor can result in a risk of electric shock. The
conductor with insulation having an outer surface
that is green with or without yellow stripes is the
equipment grounding conductor. If repair or
replacement of the cord or plug is necessary, do not
connect the equipment-grounding conductor to a
live terminal. Check with a qualified electrician or
serviceman if the grounding instructions are not
completely understood, or if in doubt as to whether
the appliance is properly grounded. Do not modify
the plug provided with the appliance — if it will not fit
the outlet, have a proper outlet installed by a
qualified electrician.
must always be followed, including the following:
a. Read all the instructions before using the
appliance.
b. To reduce the risk of injury, close supervision is
necessary when an appliance is used near
children.
c. Do not contact moving parts.
d. Only use attachments recommended or sold by
the manufacturer.
e. Do not use outdoors.
f. For a cord-connected appliance, the following
shall be included:
• Do not unplug by pulling on cord. To unplug,
grasp the plug, not the cord.
• Unplug from outlet when not in use and
before servicing or cleaning.
• Do not operate any appliance with a
damaged cord or plug, or after the appliance
malfunctions or is dropped or damaged in any
manner. Contact the nearest authorized
service facility for examination, repair, or
electrical or mechanical adjustment.
g. For a permanently connected appliance — Turn
the power switch to the off position when the
appliance is not in use and before servicing or
cleaning.
h. For an appliance with a replaceable lamp —
Always unplug before replacing the lamp.
Replace the bulb with the same type.
2-6
i. For a grounded appliance — Connect to a
properly grounded outlet only. See Grounding
Instructions.

code requirements.
PLUMBING REQUIREMENTS – GENERAL
Incoming water supply must be provided before
installation of the refrigeration unit and must comply with
local plumbing requirements.
1. A minimum 1" (2.54 cm) water supply line with a
manual shut-off valve must be plumbed at least 6 ft
(183 cm) from the unit. The incoming water supply
pressure must not exceed 70 psi static (4.8 bar) an d
be no less than 40 psi (2.8 bar) dynamic. If supply
water pressure is greater than 70 psi (5 bar), a water
regulator will be required.
2. Locate the drain hose, bracket, and two screws
provided in the installation kit. Attach the drain hose
to the water bath overflow tube located on the
bottom of the refrigeration unit.
3. Connect the water manifold supply line, located on
the bulkhead panel in the motor compartment to the
main water supply . The main water supply shut-off
valve must remain in the OFF position. If a water
filter is to be installed, connect the line to the outlet
fitting of the filter . Plumb according to applicable
plumbing codes.
Drain Hose Connection
4. When a water cooled condenser is installed, a
copper supply line (not supplied with unit) must be
plumbed to the 3/8” (.965 cm) male flare fitting
installed in the water shut-off assembly. The shut-off
must be placed in the OFF position. A copper drain
line (not supplied) is to be connected to the outlet
fitting of the water cooled condenser and routed to
the floor drain.
WATER SUPPLY
1. Models 42, 44, SC1000, 50 and SC2000 use a
1/2” ID copper water supply with a shut-off, and a
1/2” FPT connection is required for the Brix Pump
Box assemblies.
2. A 1/4” MF connection can be provided for the water
bath fill valve. This is not required if another means
of filling the water tank is available.
3. An appropriate floor drain is required within 6 ft (2 m)
of the unit.
4. Potable water connections to the equipment must
comply with the basic plumbing code of the Building
Officials and Code Administrators International, Inc.
(BOCA) and the Food Service Sanitation Manual of
the Food and Drug Administration. Verify local
plumbing code requirements.
