SAFETY INFORMATION
Recognize Safety Information
This is the safety-alert symbol. When you see this
symbol on our machine or in this manual, be alert to
the potentially of personal injury.
Follow recommended precautions and safe operating
practices.
Understand Signal Words
A signal word - DANGER, WARNING, OR CAUTION
is used with the safety-alert symbol. DANGER identifies the most serious hazards.
DANGER
Safety signs with signal word DANGER or WARNING
are typically near specific hazards.
General precautions are listed on CAUTION safety
signs. CAUTION also calls attention to safety messages in this manual.
WARNING
CAUTION
Follow Safety Instructions
Carefully read all safety messages in this manual and on your machine safety signs. Keep safety signs in
good condition. Replace missing or damaged safety signs. Learn how to operate the machine and how to
use the controls properly. Do not let anyone operate the machine without instructions. Keep your machine in
proper working condition. Unauthorized modifications to the machine may impair function and/or safety and
affect the machine life.
CO2 (Carbon Dioxide) Warning
CO2 Displaces Oxygen. Strict Attention must be observed in the prevention of CO2 (carbon dioxide)
gas leaks in the entire CO2 and soft drink system. If a CO2 gas leak is suspected, particularly in a
small area, immediately ventilate the contaminated area before attempting to repair the leak. Personnel exposed to high concentration of CO2 gas will experience tremors which are followed rapidly by
loss of consciousness and suffocation.
Shipping, Storing, Or Relocating Unit
CAUTION: Before shipping, storing, or relocating this Unit, the syrup systems must be sanitized and
all sanitizing solution must be purged from the syrup systems. All water must also be purged from
the plain and carbonated water systems. A freezing ambient temperature will cause residual water
remaining inside the Unit to freeze resulting in damage to internal components of the Unit.

GENERAL INFORMATION
IMPORTANT: To the user of this manual – This manual is a guide for installing, operating, and
maintaining this equipment. Refer to Table of Contents for page location of detailed information
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
requirements, filling water tank with water, and connection to product tanks with regulated CO2 gas pressure is
all that is required to prepare the Unit for operation.
CAUTION: Before shipping, relocating, or storing the Unit, all product coils must be
sanitized and all sanitizing solution must be purged from the coils. Ice bank must be
melted and all water drained from the water tank. A freezing ambient environment will
cause residual water remaining inside the Unit to freeze resulting in damage to internal
components.

and 75° F ambient.
Refrigerant Requirement See Unit Nameplate
Ambient Operating Temperature 40° F to 100 ° F
Electrical Requirements:
Operating Voltage See Unit Nameplate
Current Draw See Unit Nameplate
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.
