pertaining to questions that arise during installation, operation, service and maintenance, or
troubleshooting this equipment.

GENERAL DESCRIPTION

This section gives the description, installation requirements, theory of operation, design data, and flow diagram
for the Universal C-750 Four and Five-Flavor Pre-Mix Dispensers (hereafter referred to as Units).

This Unit must be installed and serviced by a qualified Service Person. This Unit contains no User serviceable
parts.

UNIT DESCRIPTION

The Universal C-750 Units are equipped with four eight-inch diameter wheels and a handle (see Figure 1)
enabling the Units to be mobile (moved from one location to another). A Water Tank Seal Kit (P/N 308979000) is
available for these Units which closes off the top of the water tank to eliminate or reduce water loss caused by
splashing during mobile movement of the Unit.

Installation of LOOSE-SHIPPED PARTS, connection to a grounded electrical outlet with proper electrical

THEORY OF OPERATION

(see Figure 2)

A CO2 cylinder delivers carbon dioxide (CO2) gas through adjustable CO2 regulators to the product tanks. When
dispensing valve is opened, CO2 pressure exerted upon the product tank contents pushes product from the
tanks, through the Unit cooling coils, and on to the dispensing valves resulting in cold drinks being dispensed.

When Unit power cord has been plugged into electrical outlet and the main power switch (115 VAC, 60 Hz Units
only) on back of Unit has been placed in the ‘‘ON’’ (up) position, the compressor, condenser fan motor, and
agitator motor will start and begin forming an ice bank. When full ice bank has been formed, the compressor
and condenser fan motor will stop but the agitator motor will continue to operate circulating ice water bath in the
water tank. The water tank ice bank sensing bulb will cycle compressor and condenser fan motor on and off as
required to maintain a full ice bank.

SELECTING LOCATION

CAUTION: This Unit is intended for indoor installation only. Do not install this Unit in an
outdoor environment which would expose it to the outside elements.

IMPORTANT: For the most efficient operation of the Unit, the ambient operating temperature for the
Unit should not exceed 90° F. Satisfactory temperatures may be obtained using blowers, air
conditioning, etc. Check your local codes.

NOTE: For identification purposes, the side of the unit that the dispensing valves are on is designated
‘‘front” of unit.

The Unit may be moved from one location to another and be set up to dispense cold pre-mix carbonated drinks.
Locate the Unit so the following requirements are satisfied.

IMPORTANT: When moving the C-750 Mobile Unit from one location to another, do not tilt the Unit more
than 45° to prevent water leakage caused by splashing of water in the water tank.

A Water Tank Seal Kit (P/N 308979000) is available for these Units which closes off the top of the water
tank to eliminate or reduce water loss caused by splashing during mobile movement of the Unit.

1. The Unit must be located near a properly fused and grounded electrical outlet with proper electrical
requirements (see Unit nameplate for electrical requirements).

2. The Unit must be located on a flat level surface and must stand solidly. Unit should be located in a shaded
area for better cooling efficiency.

CAUTION: ALLOW A MINIMUM 12-INCH CLEARANCE (TO NEAREST OBSTRUCTION)
AROUND ALL SIDES OF THE UNIT.

3. Air circulation required for cooling the condenser coil is drawn in through air intake grille on front and is
exhausted out through grilles on sides and back of the Unit. When locating Unit, make sure grilles are not
restricted (12-inch clearance to nearest obstruction) to ensure proper air circulation through the Unit.

ELECTRICAL REQUIREMENTS

DANGER: To avoid possible fatal shock or serious injury to the Operator, it is highly
reccomended that a GFCI (ground fault circuit interrupt) be installed in the electrical circuit
for the 115 VAC, 60 Hz Units. It is required that an ELCB (earth leakage circuit breaker) be

installed in the electrical circuit for the 230 Vac, 50 Hz Units.

Locate the Unit near a properly grounded electrical outlet with proper electrical requirements. The electrical
circuit must be properly fused (slow-blow type fuse) or the circuit must be connected through an equivalent
HACR circuit breaker. The electrical outlet must be accessible for ease of connecting or disconnecting the Unit
power cord. No other electrical appliance should be connected to this circuit. ALL ELECTRICAL WIRING MUST

CONFORM TO NATIONAL AND LOCAL ELECTRICAL CODES.

LOCATING THE UNIT

1. Locate the Unit on a flat level surface so that the Unit sits solidly.

185211000 8

2. The Unit should be located in a shaded area for better cooling efficiency.

3. The Unit should be close to a grounded electrical outlet with proper electrical requirements (see Unit
nameplate for electrical requirements).

DRAIN CONNECTIONS

(see Figure 3)
Drip Tray Drain Hose - The DRIP TRAY, as provided, is a closed container and must be emptied periodically. If

permanent drain is desired, cut out center of drain connection on drip tray. Be sure to remove all plastic to open
drain to its maximum inside diameter, eliminating any rough edges which will trap dirt. Install DRIP TRAY (item

3) by inserting rear edge of tray under lip of valve trim panel and lifting up until bottom tray supports are inserted
in square holes provided in front panel. Lock drip tray in place by a light downward pressure. Connect drain
