CEVj
The CEV-30j is a 4, 5 or 6-valve unit and is capable of
dispensing non-carbonated drinks only. A CO
2
cylinder
delivers carbon dioxide (CO
2
) gas through adjustable CO
2
regulators to the syrup/juice BIB pump. When a dispensing
valve is activated, pressure exerted upon the syrup BIB pump
propels syrup/concentrate from the BIB, into the dispensing
valve. Plain water enters the CEV and passes through the
cooling coils to the dispensing valve. Syrup/concentrate and
plain water meet simultaneously in the dispensing valve and
mix at the nozzle resulting in a still (non-carbonated) drink
being dispensed. The BIB syrup(s)/concentrate(s) is delivered
at ambient temperature.
CARBONATED WATER
Carbon Dioxide (CO
2
) leaves the storage tank and
arrives at the carbonator tank through the gas inlet.
Water supply enters the carbonator pump inlet at regular
street water line pressure (minimum 20 psi (137.9 KPa),
maximum 80 psi (551.6 KPa), dynamic or flowing
pressure). The water pump increases the pressure of
the water, which allows the water to flow into the
carbonator tank. The CO
2
and the water mix together in
the carbonator to produce the carbonated water that is
then sent to the soda dispenser.
The agitation of the water and CO
2
together in the tank
under high pressure creates the soda water. The quality
of carbonation (percent of CO
2
mixed in the water)
increases as the water temperature decreases and
exposure time increases.
The water level in the carbonator tank is controlled by a
water level control in the tank. This control turns the
pump motor off and on to maintain a preset level of liquid
in the tank. The water level control may be electronic
probes or a mechanical float.
SYRUP DELIVERY SYSTEM
Your syrup location can vary depending on the volume of
beverages served and ease of accessibility. Your
beverage system may set in a back storage room or
under the counter of the dispenser. Configurations are
almost limitless. Check the temperatures expected for
the storage location. Adverse temperatures can affect
the storage and quality of beverage products. It is
recommended the temperature of storage location
should not fall below 40°F (4°C) or rise above 90°F
(32°C).
BACK ROOM PACKAGE
1. Incoming tap water - should be at a minimum
dynamic pressure of 40 psi (275.8 KPa) and
maximum static pressure of 55 psi (379.2 KPa).
2. Carbonator Water pump motor - Powers the water
pump. The water pump motor is part of the
carbonator pump deck.
3. Carbonator Water pump - Pumps tap water into the
carbonator tank. The water pump is part of the
carbonator. The incoming water for the carbonator
must be first run through the pump before
connecting to the proper cold plate inlet.
4. Internal/External Carbonator tank - Combines
CO
2
gas and tap water to form carbonated water.
The “carbonator” is the carbonator tank, water pump
and water pump motor.
5. CO
2
cylinder - Holds highly pressurized carbon
dioxide (CO
2
). The CO
2
cylinder is a steel or
aluminum cylinder tank. CO
2
gas flows through the
primary pressure regulator.
6. BIB pressure gauge - Set for a minimum of 60 psi
(413.7 KPa). Indicates CO
2
pressure going to B-I-B
pumps.
