Important

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

To Avoid 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 CO2 cylinders and gauges with care. Secure
cylinders properly against abrasion.

DO Store CO2 cylinder(s) in well ventilated areas.

DO NOT Throw or drop a CO2 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. It is best to connect the
CO2 cylinder(s) to a regulator(s).

DO NOT Store CO2 cylinders in temperature above 125°F
(51.7°C) near furnaces, radiator or sources of heat.

DO NOT Release CO2 gas from old cylinder.

DO NOT Touch refrigeration lines inside units. Some

may exceed temperatures of 200°F (93.3°C).

Air Compressor Kits

Air Compressor Kit with Change-over Valve and Dump Valve — P.N. 00212135 (120 VAC),
P.N. 00214969 (120 VAC), P.N. 00217555 (230 VAC)

These instructions cover the installation and initial start-up
of the Multiplex Air Compressor Kit. An appropriate 3-wire,
15 amp power receptacle must be provided within 5 ft
(152.4 cm) of the left end of the refrigeration unit. This kit
is for use with either the Model 44 or Model 50 Fountain
Refrigeration Units and any of the Beermaster Units. Refer
to appropriate section for instructions.

GROUNDING INSTRUCTIONS

This product should be grounded. In the event of an
electrical short circuit, grounding reduces the risk of electric
shock by providing an escape wire for the electric current.
This product is equipped with a cord having a grounding
wire with an appropriate grounding plug. The plug
must be plugged into an outlet that is properly installed
and grounded in accordance with all local codes and
ordinances.

DANGER

Improper installation of the grounding plug can result
in a risk of electric shock. If repair or replacement of the
cord or plug is necessary, do not connect the grounding
wire to a flat blade terminal. The wire with insulation
having an outer surface that is green with or without
yellow stripes is the grounding wire.

Check with a qualified electrician or serviceman if the
grounding instructions are not completely understood, or
if in doubt as to whether the product is properly grounded.
Do not modify the plug provided; if it will not fit the outlet,
have the proper outlet installed by a qualified electrician.
Do not use an extension cord or an adapter plug with this
equipment.

Installing the air compressor onto a refrigeration unit

1. Align the air compressor assembly over the four (4)
holes on left end of the Multiplex Refrigeration Unit.
Secure to unit using the four (4) 1/4" screws provided in
kit (refer to figure above).

NOTE: Do not plug in pump assembly at this time. Shut “off”
main CO2 supply to refrigeration unit.

2. Locate the Air/CO2 Change-over Valve Assembly
supplied with kit (P.N. 00212506). Align the mounting
bracket of the change-over valve over the mounting
holes on the control panel (location for change-over
valve will be marked “Air/CO2 Change-over Valve”).
Mount the air/co2 change-over valve to the panel
with the #10-32 screws provided in kit (refer to figure
below).

Installing the optional dump valve onto the Multiplex
refrigeration unit

1. Connect the 1/4" line assembly provided in kit (P.N.

00212506) to the flare fitting on right side of air/CO2
change-over valve. Route the other end of tubing
to the CO2 supply manifold. Trim excess line and
connect swivel nut adapter to the remaining end of
line assembly. Secure with tab clamp. Connect the line
assembly to the CO2 supply manifold (refer to figure
below).

2. Locate the 4-1/2" section of 1/4" tubing connected at
bottom side of change-over valve. Route and connect
the remaining end of tubing to the syrup tank supply
manifold (refer to figure above).

3. Locate the 12 ft x 1/4" EVA line assembly provided in
air compressor kit. Attach the end of this line assembly,
with the swivel nut, to the outlet fitting of the air
compressor tank. Use 1/4" flare washers at swivel nut
connectors. Neatly route tubing under the stand top
and to the left side of the control panel. Connect the
line assembly with 1/4" elbow x barb (provided in kit
P.N. 00212506) to the 1/4" male flare fitting of the air/
CO2 change-over valve (refer to figure above).

4. Locate the dump valve supplied with kit. Mount the
dump valve with #10-32 self-tapping screws provided
with kit to lower left cross channel of support stand.

5. Locate the 3 ft length of tubing supplied with kit.
Neatly route and attach this line from the air tank
compression elbow to the shut-off valve compression
fitting located on top of the dump valve. Trim tubing to
correct length. Tighten compression nuts.

6. Locate the 8 ft length of tubing supplied with kit. Route
and connect this line from the 1/4" barb elbow of the
dump valve to a floor drain. Place the shut-off valve
handle in the “open” position (refer to figure above).

7. Plug the air pump power supply cord into the power
receptacle provided on wall. Pump will begin to run
immediately and shut “off” when tank pressure reaches
approximately 90 psi (6.2 bar). Pump will turn “on” when
tank pressure drops to 70 psi (4.8 bar). If not, adjust
pressure switch according to instructions located on
the inside of pressure switch cover.

8. Turn the air/CO2 change-over valve to the “Air” position.
Check for leaks.
