having an equipment-grounding conductor and a
grounding plug. The plug must be plugged into an
appropriate outlet that is properly inst alled and grounded
in accordance with all local codes and ordinances.
Improper connection of the equipment-grounding
conductor can result in a risk of electric shock. The
conductor with insulation having an outer surface
that is green with or without yellow stripes is the
equipment grounding conductor. If repair or
replacement of the cord or plug is necessary, do not
connect the equipment-grounding conductor to a
live terminal. Check with a qualified electrician or
serviceman if the grounding instructions are not
completely understood, or if in doubt as to whether
the appliance is properly grounded. Do not modify
the plug provided with the appliance — if it will not fit
the outlet, have a proper outlet installed by a

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. T o 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: Y ou 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 1 1ft-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.
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.
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.
2. Thread male coupling to its proper female half by hand to
ensure proper mating of threads.
3. Use proper wrenches (on coupling body hex and its union
nut) and tighten union nut until coupling bodies “bottom”.
REMOTE CONDENSER REQUIREMENTS
APPROVED CONDENSERS
Multiplex Condenser - TS0895-271

PRE-CHARGED REFRIGERATION LINE REQUIREMENTS
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).
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. The easiest method to create a trap is to bend the tubing
(smoothly , no kinks) into the trap form.
1. Determine a position for installation that will allow access
for maintenance and is free from obstruction. V erify 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.
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 020002365 3/122-21
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 evacuate the tubing to 250 microns.
Then recharge the tubing with 4 ounces of appropriate
refrigerant.
Excess refrigeration tubing must be properly cared
for before being connected to either the remote
condenser or the refrigeration unit.
InstallationSection 2
Important
CONNECTING THE PRE-CHARGED
REFRIGERATION LINES
When the connections are made, the seal in the
couplings are broken and if removed for any reason,
the refrigerant charge will be lost.
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 lin es 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
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.

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).
7. Turn on the circulator and carbonator. 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.
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.
Installation Checklist
Check all fittings and conduit attachments for
leaks. Check all insulated connections to make
sure that they are sealed.
Observe the pump operations for leaks.
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 “Out-of-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.
Check the water bath for full ice bank.
The stabilized water bath operating temperature
must be maintained at 33°F (.6°C) to 35°F
(1.7°C).
Close water bath feeder valve completely.

/Water Control Panel has been
2
installed on the refrigeration unit, refer to the
installation instructions for operation and testing the
circuits for leaks.
7. The carbonation circuits “A” and “B,” as well as the
syrup circuits must be checked for leaks and
possible cross circuits before turning ON the water
supply to carbonator pumps.
8. Turn on main water supply. Set incoming regulator
to 55 psi on the CO
/Water control panel. Once
2
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.
9. Set bag-in-box syrup tank push pressure CO
2
regulator to 60 psi.
PLACING THE SYRUP SYSTEM IN OPERATION

Sequence of Operation
ELECTRONIC CONTROL
Prerequisites
•Potable water must be connected to the carbonator
pump circuit.
•The ice bank water bath water must cover the
evaporator. The compressor will not start unless the ice
bank control probes are immersed in water.
•CO
Initial Power-up
The control has a 30-second delay when power is
connected, or disconnected and reconnected. The display
will show Pd30 - power delay and 30 seconds left in the
countdown cycle.
Normal Operation
NOTE: This sequence of operation includes systems
with up to two recirculation/carbonation circuits. Your
model may not employ a second circuit (44M, SC1000)
or second carbonation pump (42M).
Pressing the COMP/AGIT button will start the water bath
agitator immediately and initiate the 180 second compressor
delay. The display will show Cd99 (compressor delay & 99
seconds) and will start to count down from 99 seconds after
the first 81 seconds have elapsed. After 180 seconds the
compressor and condenser fan motor energize and the
COMP/AGIT LED flashes. Pressing the CARB A and CARB
B buttons will power the carbonator tank liquid level control.
The corresponding LED flashes to indicate the pump is
running. Pressing the CIRC A & CIRC B buttons will
immediately energize the circulating pumps and energize
the LED constantly . The display will show the circulating
temperature and show the A circuit. When two circuits are
used the readout will alternate between A and B circuits
every 5 seconds.
The compressor and condenser fan will continue to run
until ice contacts the ice bank control probe closest to the
evaporator. When ice contacts the probe, the COMP/AGIT
LED lights constantly and the compressor and condenser
fan motor de-energize.
As the ice bank melts, the ice bank control probe will lose
contact with the ice; the LED will flash and the compressor
and condenser fan motor will restart. This cycle will repeat
as required depending on load.
Power Interruption
During a power interruption the control will resume from the
point of interruption when power is reapplied and the time
delay expires. Any switches/components that were
energized when power was interrupted will be energized
when power is reapplied.

syrup circuit at a time. Repeat to sanitize additional
circuits.
You will need the following items to clean and sanitize
the Bag-in-Box (BIB) beverage system:
•Three (3) clean buckets
•Plastic brush or soft cloth
•Mild detergent
•Unscented bleach (5% Na CL O) or
Commercial sanitizer
•Bag-In-Box bag connector
1. Prepare the following in the buckets:
•Bucket 1 — warm, not to hot tap water for rinsing.
•Bucket 2 — mild detergent and warm, not to hot water.
•Bucket 3 — mix a solution of unscented bleach
(5% Na CL O) or commercial sanitizer and warm,
not to hot water. Mixture should supply 100 PPM
available chlorine (1/4 oz. bleach to 1 gallon water).
3. Rinse connector with warm tap water.
4. Connect syrup connector to BIB connector and
immerse both into Bucket 1. A “bag-side” connector
can be created by cutting the connector from an
empty disposable syrup bag.
