Caution
To Avoid Serious Injury Read the following warnings
before beginning an installation. Failure to do so may
result in possible death or serious injury.

DO Adhere to all National and Local Plumbing and
Electrical Safety Codes.
DO Turn “Off” incoming electrical service switches
when servicing, installing, or repairing
equipment.
DO Check that all flare fittings on the carbonation
tank(s) are tight. This check should be
performed with a wrench to ensure a quality
seal.
DO Inspect pressure on Regulators before starting
up equipment.
DO Protect eyes when working around refrigerants.
DO Use caution when handling metal surface
edges of all equipment.
DO Handle CO
2 cylinders and gauges with care.
Secure cylinders properly against abrasion.
DO Store CO
2 cylinder(s) in well ventilated areas.
DO NOT Throw or drop a CO
2 cylinder. Secure the
cylinder(s) in an upright position with a chain.
DO NOT Connect the CO2 cylinder(s) directly to the
product container. Doing so will result in an
explosion causing possible death or injury. Best
to connect the CO2 cylinder(s) to a regulator(s).
DO NOT Store CO
2 cylinders in temperature above 125˚
F (51. 7˚ C) near furnaces, radiator or sources
of heat.
DO NOT Release CO
2 gas from old cylinder.
DO NOT Touch Refrigeration lines inside units, some
may exceed temperatures of 200˚ F (93.3˚ C).
NOTE: Water pipe connections and fixtures directly connected to a
potable water supply shall be sized, installed and maintained in
accordance with Federal, State, and Local codes
.
KIT INSTRUCTIONS
Refer to FIGURE 1 for the following procedures.
1. The medium and low pressure regulator assembly must
be attached to the panel by two sheet metal screws
diagonally.
2. The air/C0
2 changeover valve assembly must be
positioned at the bottom of the panel with two sheet metal
screws horizontally.
3. The CO
2 changeover valve assembly for the CO2 tanks
1& 2 must be positioned on the left and slightly above the
air/CO
2 changeover valve assembly with two sheet metal
screws horizontally.
4. The low CO
2 alarm assembly must be positioned on the
upper left side and attached with two sheet metal screws
diagonally to expose the two mounting holes. The cover
must be removed to expose the two mounting holes.
5. Connect the medium and low pressure regulator
assembly to the air/C0
2 changeover valve assembly by
using the longer of the two 1/4" copper tube assemblies.
6. Connect the air/C0
2 changeover assembly to the C02
tank changeover valve assembly by using the short “U”
shaped 1/4" copper tube assembly.
7. Connect the small copper cap tube extending from the
bottom of the C0
2 control assembly box to the 1/4" MF of
the tee fitting attached to the air/C0
2 changeover valve
assembly.
8. Position the hold down clip over one section of copper
cap tube coil and attach clip to side of unit with sheet
metal screw.
9. Connect four or five 61" CO
2 gas lines to the 1/4" MF
fitting of the manifold assembly of the medium pressure
regulator.
NOTE: The fittings have check valves.
10. Connect the fifth 61" CO
2 line to the 1/4" MF fitting of the
low pressure regulator if one of the beverages is sugar
free. If all syrups are sugar based, remove the cap nut
from the remaining fitting of the medium pressure
regulator and attach the fifth CO
2 line. Install the cap nut
on the 1/4" MF fitting of the low pressure regulator.
11. Connect the two remaining 120" CO
2 plastic lines to the
CO
2 tank changeover valve. Attach the C02 line
connected to the carbonator tank in the remote unit to the
remaining 1/4" MF fitting of the C0
2 tank changeover
valve assembly.
12. Attach the two CO
2 primary regulators to CO2 tanks then
connect the two 120" CO
2 lines from the C02 tank
changeover valve assembly to the regulators. Do not
open the CO
2 tank valves at this time. Attach the C02 gas
quick disconnects to the five CO
2 gas plastic lines.

Warning
DANGER OF ELECTRICAL SHOCK - Disconnect and
lock out all electrical power sources before performing
service or maintenance on this machine -- except when
electrical tests are being performed by qualified service
personnel.

Testing For CO2 Leaks
To test the assembly to make Sure there are no leaks, the
CO
2 gas line previously installed from the carbonator tank
to the CO
2 tank changeover valve assembly will have to
be removed. Remove the cap nut from the sir/CO
2
changeover valve. Turn the knob with the directional
pointer to the left, counterclockwise.
Screw the cap nut onto the 1/4" MF where the CO
2 line to
the carbonator was removed. Turn the knob with the
directional pointer to either CO
2 tank 1 or 2. Open that
CO
2 cylinder. Adjust the primary regulator to 90 P.S.I., set
the medium pressure regulator to 60 P.S.I, and set the
low pressure regulator to 14-16 P.S.I.
Allow the CO
2 tank pressure to remain on for three
minutes, then turn the CO
2 tank handle to the "OFF"
position. The CO
2 tank gauge should remain constant, no
drop in pressure.
If the CO
2 tank gauge drops in pressure, locate source of
leak and correct. A soap solution when applied to the
connections will pinpoint the leak.
Remove the cap nut, replace the CO
2 gas line from the
carbonator tank, and screw the cap nut back on the air/
CO
2 changeover valve.
13. Wire the electrical supply to the transformer as shown in
the wiring diagram in FIGURE 2. The CO
2 control
buzzer should sound and the lamp should illuminate
when the CO
2 pressure on the primary CO2 tank
regulator drops to 70 P. S. I. and shut off when the
pressure reached 90 P.S.I.
