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.

Installation of LOOSE-SHIPPED PAR TS (see Table 2), filling the water tank with water, connection to product
tanks with regulated CO2gas pressure, and connection to an electrical outlet with proper electrical requirements
is all that is required to set the Unit up for operation.

THEORY OF OPERATION

(see Figure 2)

A CO2cylinder delivers carbon dioxide (CO2) gas through adjustable CO2regulators to the product tanks. When
dispensing valves are opened, CO2gas pressure exerted upon the product tanks pushes product from the
tanks, through the Unit cooling coils, and on to the dispensing valves resulting in cold drinks being dispensed.

When the Unit power cord has been plugged into an electrical outlet and the power switch on back of the Unit
has been positioned in the ‘‘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 the water tank. The
water tank ice bank sensing bulb will cycle the compressor and condenser fan motor on and off as required to
maintain a full ice bank.

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.

NOTE: An ELECTRICAL OUTLET, 20-AMP (item 8) is LOOSE-SHIPPED only with the 1 15 VAC, 60 Hz
Units. This electrical outlet conforms to the Unit power cord plug configuration and is to be installed
in the wall outlet box where the Unit power cord will be plugged into.

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.

INSTALLATION

FILL WATER TANK AND START REFRIGERATION SYSTEM

(see Figure 3)

NOTE: Use low--mineral--content water where a local water problem exists.

1. Make sure plug is secure in end of the water tank drain hose inside the cabinet.

2. Route water tank overflow tube out through hole in back of the cabinet to a waste container.

3. Fill water tank with clean water until water starts flowing from overflow tube into the waste container.

4. Install the Unit top cover and secure with four screws.

5. 115 VAC, 60 Hz Units only-- Replace existing fused (20A), grounded outlet with ELECTRICAL OUTLET,
20 AMP (item 8) provided in the LOOSE-SHIPPED parts.

9 309989001

WARNING: The Unit must be electrically grounded to avoid possible fatal electrical shock
or serious injury to the operator. The Unit power cord is equipped with a three-prong plug.
If a three-hole (grounded) electrical outlet is not available, use an approved method to

ground the Unit.

6. 115 VAC, 60 Hz Units only-- Make sure the main power switch, located on the back of the Unit, is in the
‘‘OFF’’ (down) position. Plug Unit power cord into electrical outlet, then place the main power switch in the
“ON” position.

230 VAC, 50 Hz Unit-- Plug Unit power cord into electrical outlet.
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 the water tank. Water will continue to drip from the water
tank overflow tube until a full ice bank has been formed, then the tube may be removed from the waste
container and stored inside the unit.

DRIP TRAY DRAIN HOSE CONNECTION

(see Figure 3)
The Unit drip tray is self-contained and must be emptied periodically. If a drip tray drain is desired, cut out the

center of the drain connection on the bottom center of the drip tray . Be sure to remove all plastic to open the
drain to its maximum inside diameter which prevents any rough edges which will trap dirt. Install the DRIP TRAY
(item 2) by inserting rear edge of the tray under lip of the valve trim panel and lifting up until bottom tray
supports are inserted in the square holes provided in the front panel. Lock the drip tray in place by a slight
downward pressure. Connect the drain hose below the drip tray to the drain connection on the drip tray. This
drain hose runs to inside of the unit and must be routed out through the hole in the back of the Unit. The drain
hose then must be routed to a waste container

CONNECTING PRODUCT TANK SUPPLY LINES TO UNIT

(see Figure 2)

NOTE: If 7/16-20 product tanks quick disconnects will be used, they may be connected directly to the
Unit product inlet lines. If connecting 1/2-16 product tanks quick disconnects directly to the Unit
product inlet lines, REDUCER FITTINGS (item 5), TAPERED GASKETS, WHITE (item 6) and TAPERED
GASKETS, RED (item 9) must be used to make the connections.

All Unit product inlet lines internal connections have been made at the factory . Perform the following to connect
the Unit product inlet lines to the product tanks or product source supply lines.

NOTE: The numbered Unit product inlet lines are labeled to identify the dispensing valves they serve.
For example: The line labeled ‘‘1’’ is connected to system that provides product to be dispensed from
NO. 1 dispensing valve. (NO. 1 dispensing valve is valve on right side when facing front of unit.)

1. Install ADAPTOR FITTINGS (item 4) in ends of the Unit product inlet lines.

2. Make up lengths of tubing (product tanks supply lines) to reach from the remote product tanks location to
the Unit product inlet lines.

3. Connect made up product tanks supply lines to the Unit product inlet lines.

4. Install 1/2-16 product tanks quick disconnects on ends of the ends of the product tanks supply lines using
REDUCER FITTINGS (item 5), TAPERED GASKETS, WHITE (item 6), and TAPERED GASKETS, RED
(item 9). The product tanks supply lines lines should be labeled for identification as to dispensing valves
they serve).

PREPARING UNIT FOR OPERATION

1. Install CUP REST (item 3) in the drip tray .

10309989001

2. Install KNOBS, DISPENSING VALVES (item 7) on the dispensing valves by pushing the knobs down in
place on the valves levers.

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.

WARNING: To avoid personal injury and/or property damage, always secure CO

cylinder in upright position with safety chain to prevent it from falling over. Should the

valve become accidentally damaged or broken off, CO2cylinder can cause serious
personal injury.

3. Open (counterclockwise) the CO2cylinder shutoff valve slightly to allow the lines to slowly fill with gas, then
open valve fully to back-seat the valve. (Back-seating the valve prevents leakage around the valve shaft.)

CAUTION: Before opening the CO2cylinder shutoff valve, turn the CO2regulators adjusting
screws to the left (counterclockwise) until all tension is relieved from the adjusting screws
springs.

4. Adjust the product tanks CO2regulator as follows:

NOTE: To adjust the CO2regulator to provide a lower pressure, loosen the adjusting screw lock nut,
then turn the screw to the left (counterclockwise) until the pressure gage reads 5-psi lower than the
new setting will be. Turn the adjusting screw to the right (clockwise) until the gage registers the new
setting. Then tighten the lock nut.

Set the product tank CO2regulator using the Cornelius PRE-MIX COMPUTER slide rule or the bottling room
chart. Enter equilibrium pressure for the highest temperature encountered between the product tank storage
area and the Unit plus 5 psig operating pressure for lines 10 feet in length or less and no vertical lift. Add one
pound for every 10 feet over initial 10 feet of product tank to Unit line length and one pound for every 2 feet of
vertical lift. Add one pound for every product tank on line over three tanks. MAXIMUM UNIT INLET PRESSURE
MUST NOT EXCEED 100 psig. Loosen lock nut on the CO2regulator adjusting screw, then turn the adjusting
screw to the right (clockwise) until the gage registers the desired pressure. Tighten the adjusting screw lock nut.

IMPORTANT: To prevent off-taste of the dispensed product, the product systems must be sanitized to
remove residue that may be present inside the Unit cooling coils.

5. Sanitize all Unit product systems as instructed in the Operators manual (P/N 309989002).

6. Connect full product tanks into the product systems. Check for leaks and tighten any loose connections.

UNIT OPERATION

1. Dispense from each dispensing valve until all air is purged from the product systems and only product is
dispensed.

2. Check for leaks and tighten any loose connections.

3. Adjust dispensing valves for product flow rate by turning dispensing valve compensator adjusting screw
(see Figure 3) to the left (counterclockwise) for higher product flow rate or to the right (clockwise) for a
