Carbon Dioxide (CO2) displaces oxygen. Exposure to a high concentration of CO which are followed rapidly by loss of consciousness and suffocation. If a CO particularly in a small area, immediately ventilate the area before repairing the leak. CO 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 may build up in an area, venting of the BIB pumps and/or CO

monitors must be utilized.

ELECTRICAL REQUIREMENTS

Refer to Ice Machine Model/Serial Plate for voltage/amperage specifications.

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 installed and grounded in accordance with all local codes and ordinances.

NOTE: The 208/230V units are not equipped with a cord.

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.

i. For a grounded appliance — Connect to a

properly grounded outlet only. See Grounding Instructions.

A 1" (2.54 cm) ID copper inlet water line equipped with a 3/4" (1.905 cm) FPT sweat adapter with shut-off must be supplied by plumber at rear of equipment. Appropriate floor drains must be provided within 6 ft (183 cm) of each unit installed.

NOTE: The carbonator in this unit is provided with a dual check valve type back-flow preventer, which conforms to ASSE 1032. The Model 50M & 44M vented backflow preventer conforms to ASSE 1022.

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.

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) and 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. Use the built in fill valve that is already plumbed into the unit.

2. An appropriate floor drain is required within 6 ft (2 m) of the unit.

3. 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.
