Safe Installation Dos and Don’ts
•
DO NOT exhaust CO2 gas (example: syrup pump)
into an enclosed area, including all types of walk-in
coolers, cellars, and closets.
•
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).
! Warning
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 are tight. This check
must 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.
•

! Warning
Carbon Dioxide (CO2) displaces oxygen. Exposure
to a high concentration of CO2 gas causes tremors,
which are followed rapidly by loss of consciousness
and suffocation. If a CO2 gas leak is suspected,
particularly in a small area, immediately ventilate the
area before repairing the leak. CO2 lines and pumps
must not be installed in an enclosed space. An
enclosed space can be a cooler or small room or
closet. This may include convenience stores with
glass door self serve coolers. If you suspect CO2
may build up in an area, venting of the BIB pumps
and/or CO2 monitors must be utilized.

INSULATING CONNECTIONS
1. Make sure all exposed carbonated water and syrup
lines are well insulated on towers to conduit, conduit
junctions, refrigeration unit to conduits, and drivethrough
junction.
2. To insulate the above, use the leftover conduit sections
and tape.
3. Cut the conduit sections to fit snugly over the exposed
lines and fittings. A little extra time spent doing a
thorough job initially will eliminate a call back in several
days to make corrections.
NOTE: Do not inject foam material directly on the
connections where the tubing connects to the barb fittings or
directly on poly tubing.
NOTE: You must use a wrench on the body to keep the
body from turning while tightening the nut with the second
wrench. If the body turns excessively, the piercing seal will
be damaged.
4. Use proper wrenches to tighten an additional 1/4 turn
(90°). This final 1/4 turn is necessary to ensure the
formation of a leak proof joint. Alternately, use a torque
wrench to tighten the 1/2” coupling to 40 ft-lbs and 3/8”
fitting to 11 ft-lbs.
5. Leak check all your connections. If you detect any leaks,
repair and recheck.
Condenser and Pre-charged Lines Installation
Before proceeding with installation, verify that all
requirements for roof mounted remote condenser units (if
applicable) have been satisfied. If unit has a remote
condenser, refer to the instructions on installing the remote
condenser supplied with the condensing unit and refer to the
section on installation of remote refrigeration line sets.
Aerosol Foam
Important
Chase
4. The can of foam is to be used to fill the openings
between the conduit insulation and the inside diameter
of the floor chases. The purpose is to provide an air tight
seal at the floor level to prevent foreign matter from
entering the chases. Please read the foam
manufacturer’s instructions carefully. We recommend
using the adapter with the right angle extension.
5. Insert the adapter into the openings approximately 1" to
2" (2.5 to 5.1 cm) while depressing the adapter.
6. Move the extension around throughout the area where
the foam is to be placed. Do not over fill, allow room for
expansion. If the chase opening is too deep insert a
section of the leftover conduit insulation in the opening
prior to using the foam insulation.
Aeroquip Connection
1. Lubricate male half diaphragm and synthetic rubber seal
with refrigerant oil.
If you are installing a remote unit, there is a
refrigeration king valve located behind the
compressor. This valve must be back seated prior to
starting the compressor. Failure to do so will short
cycle and may damage the compressor.
REMOTE CONDENSER REQUIREMENTS
APPROVED CONDENSERS
Multiplex Condenser - TS0895-271

Section 2
Installation
PRE-CHARGED REFRIGERATION LINE REQUIREMENTS
Important
If you have a MAC Multi-Pass condenser please add
three (3) pounds additional charge.
1. Both the discharge and liquid remote condensing lines
must be kept to a minimum distance for maximum
performance. All Multiplex systems are capacity rated to
100 ft (30.5 m) tubing distance between the compressor
and condenser. If you have another brand condenser,
please add additional charge for the condenser (example:
up to three (3) pounds for a MAC condenser).
1. Determine a position for installation that will allow access
for maintenance and is free from obstruction. Verify hot air
discharge from other condensers does not interfere with
the inlet of this condenser.
2. Install the four legs to the sides of the condenser using
the mounting bolts provided.
3. The General Contractor or Owner must secure two
treated lumber 4" x 4" x 36" (or longer). You may then
mount the remote condenser to the treated lumber.
4. The General Contractor or Owner must install a 3" pitch
pot in the roof. Then seal for weather protection.
2. Any vertical rise 25 ft (7.62 m) or greater must have a
manufactured or installed trap (bend), in the discharge
refrigeration line from the compressor to the remote
condenser. A trap is necessary for every additional 25 ft
(7.62 m) vertical rise. When excessive vertical rise exists,
this trap allows oil to reach the condenser and return to
the compressor.
3" Pitch
3. The easiest method to create a trap is to bend the tubing
(smoothly, no kinks) into the trap form.

4. The trap(s) must be of minimum height of 3" (7.6 cm) and
a width of 6" (15.2 cm) to minimize oil accumulation. The
traps can also be bent out of the refrigeration tubing.
Carefully bend the tubing down 12", and then sweep the
tubing back up.
5. It is critical that the Multiplex remote condensing line size
specifications for the specific model be maintained. The
specifications are 1/2” discharge and 3/8” liquid lines.
INSTALLING THE MULTIPLEX REMOTE CONDENSER
The Multiplex remote condensing units have a 208-230 Volt,
50/60 HZ, 1 PH fan motor that includes a permanent split
capacitor and internal overload protection. The electrical wires
from the refrigeration unit wire to the condenser. The electrical
installation must be in accordance with local codes, National
Electrical Code and regulations.
Part Number 020001552 5/11
5. Locate the pre-charged refrigeration lines shipped with
the system. These lines must be a correct length for the
building design. Avoiding any kinks, neatly route these
lines from the remote condenser to the refrigeration unit.
Excess refrigeration tubing must be handled in one of two
ways. When coiling the excess tubing, make sure the
inlet to the coil is at the top of the coil and the exit is the
bottom of the coil. There can be no more than one turn to
the coil. If you have more tubing, you must cut out the
excess before connecting the ends. When cutting the
tubing, you must first evacuate the refrigerant (line sets
have a positive refrigerant holding charge of two to three
ounces). After shortening and welding the tubing together
again, you must vacuum the tubing to 250 microns. Then
recharge the tubing with the appropriate refrigerant at 4
ounces per length of tubing.
! Caution
Excess refrigeration tubing must be properly cared
for before being connected to either the remote
condenser or the refrigeration unit.
2-17
Installation
CONNECTING THE PRE-CHARGED
REFRIGERATION LINES
NOTE: Before connecting the pre-charged refrigeration
lines, the refrigeration unit must be properly located,
leveled, and the water bath filled 1" (2.5 cm) below the
installed drain pipe.
1. Attach low side gauge set to service port on each
line set to verify positive pressure within the line set.
NOTE: If for any reason the lines are damaged and/or
leaking or the lines no longer charged, refer to “How To
Re-charge the Line Sets”. If the line set is too long for
the application, refer to “How to Shorten the Line Sets” in
Section 3.
2. Always make the connections at the condenser first,
using the end of the pre-charged lines with the valve
ports.
3. Connect the condenser side with the quick
connectors (discharge and liquid) up to condenser.
Refer to the section titled “Aeroquip Connection” in
these instructions.
4. Connect the refrigeration unit side with the quick
connects (discharge and liquid). Make sure to
provide a discharge trap at back of refrigeration unit,
or bend discharge line down 12" and then up
smoothly (no kinks) to provide a trap.
5. If a low refrigerant charge is detected, recover and
recharge the system adding the unit name plate
charge.
6. Repair any damages to the line sets before
proceeding.
TESTING CO2 CIRCUIT FOR LEAKS
It is advisable to test the system for leaks before turning
ON the water supply to the carbonator and connecting
the syrup tanks. If a leak does exist, it will be easier and
faster to make any correction.
1. Turn ON the CO2 supply and adjust the primary
regulator to 90 psi (6.2 bar).
2. Position the CO2 tank changeover valve handle (if
applicable) toward this regulator.
Section 2
operating gauge). The needle may drop
approximately 1 psi (.09 bar), but must remain
constant and not lose pressure. Wait for several
minutes.
If pressure continues to fall, this indicates there is a leak
in the system which must be corrected.
The greater the leak, the faster the pressure will drop.
The smaller the leak, the slower the gauge will drop.
It may be necessary to use a soap solution at all
connections to locate a very small leak.
CO2 gas must be present on all valves of the tower(s)
NOTE: All soap solution must be rinsed thoroughly from
tubing upon completion of testing.
TESTING SYRUP CIRCUIT (5 GALLON TANKS ONLY)
Before connecting the syrup tanks to the system, the
syrup circuits must be tested for leaks with CO2 gas.
1. Connect an empty syrup tank to pre-mix syrup
circuits.
2. Connect one of the CO2 gas quick disconnects to
this tank. Allow the tank to fill with CO2 gas.
3. Observe the pressure of the primary CO2 tank
regulator (not the 90 psi [6.2 bar]).
4. Allow the CO2 tank pressure to remain ON for a few
seconds. This will allow the lines to expand to
operating conditions.
5. Turn OFF the CO2 tank cylinder.
6. Check all connections from the syrup tank through
the connections in the water bath area to all fittings
at rear of tower.
7. Check syrup circuitry on the tower by activating the
valve.
8. Follow the same procedure for the diet pre-mix
beverage circuit.
If no leaks are found in the syrup circuits and the
carbonated water circuit, the system is ready to be
insulated and placed in operation.
3. Move the air/CO2 changeover valve to the CO2
position (if applicable).
4. Allow the CO2 gas to enter the system.
5. Wait for 2 or 3 minutes before turning OFF the CO2
tank valve. This will allow the lines to expand under
pressure.

Installation
Start-Up
1. Turn on main water supply, set incoming regulator to 25
PSI (must be lower than CO2 supply pressure). Once
water is supplied to the unit air needs to be purged from
the carbonator tank. Do so by lifting press relief valve
tab until water comes out of relief valve.
Set Incoming Water to
Regulator to 25 psi
Note: Turn this switch OFF to perform any operations in the
water bath area.
With water bath water temperature of 65°F (18°C), ice must
begin to form on the evaporator coils in approximately 2
hours. The unit will build a full ice bank in approximately 4 to
6 hours (depending on ambient water temperature).
Water Bath
Tank
Overflow Tube
Drain Tube
Tab Clamp
NOTE: Always set the water pressure to 25 psi first and only
when no CO2 pressure is present. The CO2 pressure will
bleed back and raise the water pressure gauge.
2. Turn on main CO2 supply, set regulator initially to 26 psi,
can raise incrementally to 30 psi if their is no excessive
foaming.
3. Set bag-in-box or syrup tank push pressure CO2
regulator to 35-40 psi.
Main CO2 Supply Set to 26-30 PSI
4. Before turning on the carbonator or circulator switch,
verify that the pump box assembly has been mounted
and connected to the unit and the appropriate syrup and
water has been supplied.
5. Turn on the main water supply to the booster assembly.
Verify the booster is plugged in and that the accumulator
tank valve is open. (If the system has an optional “Outof-Syrup” device, verify that it is unplugged.)
6. Verify the pump is running. Place the valve on the right
side of the pump box in the purge position until all air
bubbles have passed through the line. Turn the valve
back to “dispense”. Plug the Out-of-Syrup device power
cord into an appropriate wall outlet at this time (if
supplied).
NOTE: Verify that the pump box holding tank is full before
proceeding.
Preparing Ice Bank
BUILDING AN ICE BANK
1. At this time, fill the unit water bath tank to the top, or within
1/2” (1.3 cm) of the top minimum, of the overflow tube.
Use a garden hose or another water supply to do this.
NOTE: A manual fill valve is incorporated into the water circuit
to the carbonator tank. This valve can be used to manually
add water lost for any reason. Do not leave this valve ON
constantly, only use it for filling and topping off. The water bath
must be drained, flushed, and refilled every six months.
2. Turn ON the switch labeled “Refrigeration”. Allow unit to
run for about 15 minutes before proceeding to step 3.
7. Turn on the circulator and carbonator switches. The
carbonator must run for approximately 1 to 3 minutes
and shut off. The circulator must run continuously. Verify
that water is returning to the water bath through the
return bulk head fitting.
Important
Wait until a thin layer of ice has begun to form on the
evaporator before proceeding any further.
8. Go to the tower(s) and brix the valves. Using a syrup
separator and volume cup, adjust the flow rate of the
carbonated water to two fluid ounces per second. Then,
using the separator and a brix cup, adjust the syrup flow
rate for a ratio of carbonated water to syrup to 5 to 1.
3. Turn ON the switch labeled “Agitator”.

Section 3
How the Multiplex Works
Sequence of Operation
The Model 11M is a 1/2 HP refrigeration unit that will
provide premix carbonated beverages and chilled
carbonated water for up to 12 gal (45 L) of
syrup/day or 560 drinks/day (4,000 gal/year) with a
100 ft (30 m) maximum conduit length. This is a remote
refrigeration unit that derives its peak draw capacity from
the reserve ice bank produced from a capillary tube
refrigeration system. This system is controlled to cycle
ON and OFF by the operation of the ice bank control.
The sensing bulb that controls the ice bank is located on
an adjustable bracket in the water bath.
PRE-MIX REFRIGERATION UNIT
Ice Bank Is Required
WATER BATH ACCESS
• Has a round hole in the front and back panels with
no edge trim to protect lines.
1. Check water bath for full ice bank.
2. The stabilized water bath operating temperature
must be maintained at 33°F (0.6°C) to 35°F (1.7°C).
The following is a sequence of operations for the
Multiplex Pre-mix Beverage equipment.
1. Once a drink is dispensed, the following will occur:
A. For a Syrup Tank System, the Pre-mix syrup is
manually mixed at the store. Pre-mix beverage
is then transferred to a holding tank for supply to
the Multiplex system.
B. For a Bag-In-Box System, pre-mix syrup is
drawn from a Bag-In-Box by means of a gas
driven syrup pump.
2. The brix pump mixes a 5:1 ratio pre-mixer syrup and
water into a 3 gallon holding tank located in the
pump box (the 3 gallon tank is vented to
atmosphere).
3. The carbonator pump (stainless) pulls the 5:1
pre-mix out of the 3 gallon holding tank and injects it
into the pre-mix carbonator tank where the CO2
pressure is 35 psi (2.4 bar) on the tank.
4. The circulator pump runs continuously and
circulates water bath water through the conduit to
provide cooling for all drinks.
• End panel has two ovals in the rear of the panel with
edge trim to help protect conduit lines.
SERVICE ACCESS
• Front panel was solid and did not allow easy access for service.
• Switch panel was mounted flush to end panel.
