GROUNDING INSTRUCTIONS
When using electric appliances, basic precautions
The beverage/ice machine must be grounded in
accordance with national and local electrical codes.
This appliance must be grounded. In the event of
malfunction or breakdown, grounding provides a path of
least resistance for electric current to reduce the risk of
electric shock. This appliance is equipped with a cord
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
qualified electrician.
must always be followed, including the following:
a. Read all the instructions before using the
appliance.
b. To reduce the risk of injury, close supervision is
necessary when an appliance is used near
children.
c. Do not contact moving parts.
d. Only use attachments recommended or sold by
the manufacturer.

InstallationSection 2
Pulling Conduit Through Floor Chase
1. Determine the most convenient way of routing
conduit, starting at the end which offers adequate
room for installation. The conduit installation process
requires the assistance of at least two (2) qualified
personnel.
2. Route the steel fish tape through chase opening.
Push fish tape through entire chase until it appears
at opposite end.
3. Locate an appropriate length of rope and tie to end
of fish tape (end which was routed through chase in
step 2). Approximately 2 ft (0.6 m) from steel fish
tape/rope connection, secure a swab to rope (use
mop heads or a bundle of rags for swab).
4. Pull end of fish tape from starting point through
chase with rope and swab. The swab will clean any
construction materials, moisture, or debris that may
exist in floor chase. Continue to swab the chase until
the swab exits the chase clean and dry.
5. After floor chase has been cleaned, remove steel
fish tape and swab from rope. Locate bundle of beer
conduit and unspool conduit to allow unrestricted
feed during installation process.
6. Locate rope through floor chase opening and
connect to proper end of beer conduit.
NOTE: The beer conduit is designed to be pulled
through floor chase in the direction of arrows printed on
conduit.
7. After rope has been connected, t ape end of co nduit,
including rope, and form conduit end to a point (see
figure above). Tape will ensure that no contaminants
enter conduit tubes during installation.
8. Place pointed end of the conduit through chase
opening. While one person pushes the conduit
through chase, another person should be pulling the
conduit through the chase with rope at the opposite
end.
9. Once the conduit has been routed through the
chase, pull enough conduit through the openings to
ensure an adequate supply at each end of the chase
for connections.

CONNECTING BEER CONDUIT
Before connecting the beer conduit at the walk-in beer
cooler and beer towers, ensure an adequate length of
conduit is being supplied to make proper connections.
Only an approved cutting tool should be used to cut
polyethylene tubing. The cutting tool should contain
a razor sharp cutting blade so that the tubing will not
be crushed when cutting. A razor blade knife or
butterfly tubing cutter is sufficient (see figures).
Multiplex packs a butterfly cutter with each
Beermaster Glycol Chiller.
1. Locate the lines of the beer conduit routed to the
Beermaster Glycol Chiller.
2. Using an approved cutting tool, cut the beer conduit
insulation along the top side while peeling insulation
back at the same time.
NOTE: Glycol circuit is a pair of lines; one blue and one
red. The blue line is the discharge or su pply line. The red
line is the return line.
3. Locate the return glycol supply lines of the beer
conduit and connect to the corresponding John
Guest fitting on the Beermaster Glycol Chiller.
4. Locate the discharge glycol supply lines of the beer
conduit and connect to the corresponding John
Guest fitting on the Beermaster Glycol Chiller.
5. Locate the glycol lines in the main conduit. Connect
the glycol lines of the beer unit to walk-in cooler
conduit to the glycol lines of the main beer conduit.
6. Locate the beer and glycol supply lines at the
dispensing station. Connect each beer line,
incoming glycol line, and outgoing glycol line to the
appropriate John Guest fitting at the dispensing
station.
NOTE: The 3/8" I.D. poly line used in the beer conduit is
thin wall tubing. Barbed fittings should not be used. The
usage of barbed fittings causes thin wall tubing to split or
crack and leaks will result.

INSTALLING THE CONDUIT KIT
Connections Preview
Review the three previous illustrations to determine
which best illustrates your particular installation.
Consider the following while examining the drawings:
Beer conduits have been designed to achieve the proper
cooling of each encased beer line. In order to function
properly, you must follow these guidelines:
Up to eight line conduit:
•six beer maximum, one glycol circuit (two lines)
Ten and over line conduit:
•two glycol circuits (four lines)
To ensure colder dispensing temperatures, glycol should
flow directly to the dispensing towers before returning to
the remote Glycol Chiller Unit. After examining the
drawings determine the desired glycol circuit to be
achieved and illustrate on paper for referral. Do the
same for the assignment of the beer supply lines.
Connecting the Glycol Chiller to the Walk-in Cooler
or Main Beer Conduit
1. Route the glycol conduit(s) from the Beermaster
Glycol Chiller to the point of connection on the main
beverage conduit(s). This connection could be done
in the walk-in cooler or at any desired location along
the length of the main beer conduits.
2. Identify the proper glycol lines within the glycol
conduit(s) at the Beermaster Glycol Chiller, cut to
length and insert into the appropriate John Guest
bulkhead fitting(s) found on the side panel of the
Beermaster Glycol Chiller as shown below.
Connecting Main Beer Conduit at Walk-in Cooler
1. At the top of each beer wall bracket fitting, found on
the dual secondary regulator, secure a Beer Nut,
John Guest adapting tail piece, washer, and 1/2"
John Guest union (see the following image).
2. Identify the appropriate beer lines to be connected
to each of the wall bracket fittings, cut to length and
insert into the proper John Guest 1/2" connector as
shown below.
Connecting Beer Conduit to the Tower
Glycol lines in
1. Peel the insulation back from the end of the beer
conduit to expose all lines. Locate the appropriate
glycol circuit lines, cut to length and attach a 1/2"
John Guest union to each line (see the “Tower
Connections” image).
2. Attach the opposite end of each 1/2" John Guest
union to the 1/2" adapter located at the base of the
dispensing tower.
3. At the walk-in end of the conduit(s), peel back the
insulation from the beer conduit and identify the
appropriate glycol circuit and lines to be connected
(blue and red). Cut glycol lines and secure to the
appropriate elbow or union connections that are best
suited for connection with the beer conduit.

NOTE: If conduit contains more than one glycol circuit it
will be necessary to attach U-bends for each of the
additional circuits. Use a 1/2" U-bend quick connect
fitting or the U-bend can be built by att aching two (2) 1/2"
John Guest elbows to one another by means of a 2"
length of 1/2" tubing.
BEER RESTRICTOR LINES
1. Refer to the section on “Balancing the System” in
this manual for determining the required length of
restrictor line. Calculate the required length for each
faucet. Cut each restrictor line to the calculated
length and carefully insert the 3/16" Barb x 1/2" John
Guest adapter and clamp securely with the
adjustable clamps provided (see the “Tower
Connections” figure).
2. Identify the beer line to be connected to each of the
appropriate restrictor line, cut the beer lines to
length and attach a 1/2" John Guest Union to each.
Neatly wrap the excess restrictor line securely
around the glycol supply lines to ensure good heat
exchange. Connect the adapter from each restrictor
to the 1/2" connector of each of the appropriate beer
lines.
Connecting Main Beer Conduit to Branch Beer
Conduit
1. At the required point of connection carefully split
open and fold back the insulation on the main beer
conduit and identify the correct set of glycol lines
(circuit) to connect to the branch beer conduit. Cut
the glycol line(s) and attach the appropriate 1/2"
elbow or union connections that are best suited to
connecting with the main beer conduit (see the
“Main Beer Conduit Connections” figure).
2. Peel the insulation back from the end of the branch
beer conduit to expose all lines. Locate the glycol
circuit lines, cut to length and insert each line into
the open end of the previously attached 1/2"
connectors at the main beer conduit (see the “Main
Beer Conduit Connections” figure).
3. Locate the appropriate beer line(s) in the main beer
conduit to be connected to the branch conduit. Cut
desired beer line(s) long so that they can be pulled
back and then routed in a smooth curve into the
branch conduit. Attach appropriate beer line(s) from
main beer conduit to beer line(s) in branch beer
conduit with 1/2" John Guest Union(s).

STARTING UP THE SYSTEM
To avoid agitation use only straight unions when
splicing beer lines.
Before Starting Up the System
Each of the steps below should be done 24 hours prior
to the tapping or dispensing of any beer.
1. Place all kegs in a walk-in cooler at 36°F to 38°F
and allow them to temper properly.
2. Turn ON the Beermaster Glycol Chiller circulating
glycol pump(s).
3. After leak testing all glycol and beer supply lines,
wrap the lines firmly with foil (to ensure a good heat
exchange) and then insulate all lines; to ensure a
minimum of 1" insulation over all areas of exposed
beverage line.
4. After glycol has circulated through system for
approximately one hour, remove the strainer from
the glycol bath. Flush the strainers clean with fresh
water and reinstall.

Balancing the System
DETERMINING RESTRICTOR LINE LENGTH AND
APPLIED KEG PRESSURE
In order to ensure a proper, foam-free, beer flow from
each faucet, the following instructions and calculations
must be completed. Use the formulas found in this
section to determine the required restrictor line length
and applied keg pressure needed for each beer line. In
order to complete these calculations the following
information will be needed:
•Brands of beer to be dispensed.
•Temperature of the Walk-in Cooler (default 38°F
[3.3°C]).
•Altitude (distance above sea level).
•Total line length for each beer line.
•Overall lift or drop for each beer line.
T o determine the appropriate Applie d Keg pressures
and Restrictor Line Lengths see attached work
sheets.
1. First determine which brands of beer will be
dispensed at which faucet. Use one work sh ee t t o
record data for each faucet.
2. Determine keg temperature at cooler.
3. Determine the type of push for the beer to determine
which work sheet to use to calculate flow of beer.
4. Follow the instructions for that particular work sheet.
1. Adjust the primary CO
regulator to 40 PSI and
2
secure the lock nut.
2. If a blender is utilized proceed with adjustments
provided with blender kit.
3. Adjust the secondary regulators. It is recommended
that when applied keg pressures exceed 20 PSI the
secondary regulators be adjusted 2 PSI below the
calculated pressure. If more pressure is required
after tapping keg, increase as needed.
4. Tap the kegs and proceed to draw beer from each
valve one at a time. Ensure each brand is properly
drawing before proceeding to the next. The proper
flow rate for beer at each valve is 2 ounces per
second. Beer should be flowing clear with a full flow
from the dispensing faucet (a considerable amount
of dispensing may be needed).
5. Secure all secondary regulator lock nuts and
complete the information label, identifying the
product and its applied keg pressure for each
appropriate regulator.
6. Instruct operator on proper maintenance and
operating requirements.

instructions on installing the Remote Condenser
supplied with the unit.
If unit is to rest on floor, locate four 6" (15.2 cm)
adjustable legs (optional). Screw and tighten legs into
the bottom of the refrigeration unit. Set unit in desired
location and adjust legs until unit is level and sturdy. If
unit is to be mounted on stand, position stand and
secure unit to stand. If unit is to be installed on a wall
mount bracket, install wall mount bracket and position
unit on bracket at this time. Fasten unit to bracket with
bolts provided.
EQUIPMENT PLACEMENT
NOTE: All Refrigeration Units must be mounted on
either 6" legs or optional stand.
1. Move the stand/refrigeration unit to the designa te d
area and position it near the wall at a distance of at
least 6" (15.2 cm) for air circulation in air-cooled
units, or at a distance required by local code.
2. Level the stand/unit by adjusting the leg levelers
provide on the legs or stand.
3. If unit is equipped with optional stand, lift the
Refrigeration Unit onto the stand. Position the unit in
the center of the stand. Be sure to orientate the drain
of the refrigeration unit with the drain access hole of
the stand. Secure with 5/8"-11 x 1" bolts supplied in

INSULATING CONNECTIONS
1. Make sure all exposed lines are well insulated on
towers to conduit, conduit junctions, refrigeration
unit to conduits.
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 co ndensing unit and
refer to the section on installation of remote refrigeration
line sets.
Aeroquip Connection
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 app ro xim at ely
1" to 2" (2.5 to 5.1 cm) while depressing the adap te r.
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.
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”.
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.
1. Installation and maintenance are to be performed
only by qualified refrigeration personnel. These
technicians must have EPA certification (USA), are
familiar with local codes and regulations, and are
experienced with this type of remote refrigeration
equipment.
2. As a condition of the warranty, the check, test and
start-up procedure must be performed by qualified
personnel. Because of possible shipping damage ,
check both the condensing unit and refrigeration
unit(s) for refrigerant leaks.
3. If the refrigeration unit is located on a roll out
platform, you must coil up to one round between the
back of the stand and the wall. This allows pull out of
the refrigeration unit for servicing.
4. If the refrigeration unit is located in a stationary
location, you must remove excess refrigeration
tubing as described below.
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 conde n ser.
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.
Verify hot air dischar ge from other conden se rs do es
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 inst allation must be
in accordance with local codes, National Electrical Code
and regulations.
2-20
5. Locate the pre-charged refrigeration lines shippe d
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.
Part Number 000003913 7/08
Section 2Installation
!
Caution
Excess refrigeration tubing must be properly cared
for before being connected to either the remote
condenser or the refrigeration unit.
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 Set s” 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.

location. Conduit (an insulated bundle of tubing)
connects the refrigeration unit and kegs of beer to the
tower. The conduit has the beer and glycol lines
wrapped together and the glycol is circulated to keep the
beer in the conduit lines cold. The refrigeration system is
controlled by a sensing bulb located on an adjustable
bracket in the glycol bath. Depending on the setpoint of
the temperature control, the refrigeration system cycles
ON and OFF as the temperature of the glycol bath
changes.

ProblemPossible CauseTo Correct
Section 1: Restriction
Too little restriction
Too much or too little restriction in a draught beer system will cause drawing problems. If draught beer system does not have
enough restriction it may cause the following problems:
A recovery problem simply means that
the beer is leaving the beer line faster
than the keg can fill the line. When this
occurs it creates a vacuum in the keg
which acts as if there was a low pressure
on the beer in the keg. This causes the
to come out of the beer line causing
CO

foaming problems. (The following
symptoms occur most frequently during
the high volume time of day.)
Beer draws too fast. If the beer draws
clear but too fast and the pressure is
properly set, there may not be enough
restriction in the system.
If a draught beer system is over restricted it may cause the following problems:
Beer draws too slowBeer draws too slowly with little or no
When drawing one beer, the beer
flows very fast.
If a pitcher is drawn, the beer starts
clear then starts to show intermittent
streaks of foam followed by all foam.

The beer appears to flutter or swirl
out of the faucet causing the CO

creating excess foam.
Since the recovery problem symptoms
simulate a low pressure problem, check to
make sure that the CO

Refer to your records to recheck your
restriction calculation for the system. If you
find your line does not have enough
restriction, add the extra restriction to the
3/16" end of the beer line. If you have no
records, make up a new beer line with the
proper restriction and replace the existing
line.
Follow the second corrective step above.
If the beer still flows too fast, continue to add
more 3/16" restrictor line to the system to
meet the retailer’s needs.
First, ensure that the keg is properly tapped.
Second, ensure that the CO

When troubleshooting a closed remote system, one should consider the following areas:
TemperatureBeer draws warm and is all foam.Check coolant circulation by:
• Inspecting the coolant circu lation pump to
ensure it is on and running.
• Inspecting the coolant return line in
reservoir to ensure it is circulating. Replace
pump if necessary.
Check coolant temperature by:
• Adjusting the range from 27°F (-2.7° C) to
29°F (-1.6°C).
• Fill reservoir to proper level with 3:1 glycol
mix.
No beer flows through system.Check tap check ball and free if stuck. Check
Coolant temperature. If it is less than 27°F
(-2.7°C), the beer in the lines may be frozen.
Turn OFF coolant compressor, then adjust
coolant temperature to be between 27°F
(-2.7°C) and 29°F (-1.6°C).
