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
CO2Displaces Oxygen. Strict Attention must be observed in the prevention of CO2(carbon dioxide)
gas leaks in the entire CO2and soft drink system. If a CO2gas 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 CO2gas will experience tremors which are followed rapidly by
loss of consciousness and suffocation.
Shipping, Storing, Or Relocating Unit
CAUTION: Before shipping, relocating, or storing this Unit, the product coils must be flushed with
potable water, all water must be purged from the product coils, ice bank must be melted, and water
must be drained from the water tank. A freezing ambient environment will cause residual water remaining inside the Unit to freeze resulting in damage to the Unit internal components.

UNIT DESCRIPTION
The Unit (see Figure 1) is equipped with manually operated self-closing dispensing valves. The Unit is equipped
with a handle and wheels which makes it a mobile Unit. The refrigeration system is equipped with a 3/4 H.P.
compressor that is easily accessible for service and maintenance.
THEORY OF OPERATION
(see Figure 4)
A CO2cylinder delivers carbon dioxide (CO2) gas through adjustable CO2regulators to the product tanks. When
dispensing valves are opened, CO2pressure exerted upon the product tanks pushes product from the tanks,
through the Unit cooling coils, and on to the dispensing valves resulting in cold dispensed drinks.
When Unit power cord has been plugged into the electrical outlet and power switch (115 VAC, 60-Hz Units only)
on back of the Unit has been positioned to ‘‘ON’’ (up) position, the compressor, condenser fan motor, and agitator motor will start and begin forming an ice bank. When a 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 water
tank. The water tank ice bank sensing bulb will cycle the compressor and the condenser fan motor on and off as
required to maintain a full ice bank.
