REQUIRED TOOLS
• Steel Fish Tape
• Length of Rope
• Duct Tape
UNPACKING AND INSPECTING
Carefully inspect the conduit immediately upon unpacking. Inspect conduit for any damages that may have occurred during shipping.
ROUTING MULTIPLEX CONDUIT
FLOOR CHASES
FIGURE 1
• Approved Tubing Cutters
• Razor Blade Knife
• Tab Clamp Pliers
Before installing conduit, be sure conduit is proper length
for installation, contains the correct number of lines for
connection, and all lines are proper diameter.
Before pulling Multiplex conduit through a floor chase, ensure the floor chase contains the following:
• 8" Minimum PVC Conduit
• Wide Sweep Elbows with a minimum 2 ft
(61 cm) radius
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 two (2) qualified personnel.
2. Locate steel fish tape and route through chase opening. Route 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 that was routed through chase in
step 2). Approximately 2 ft (61 cm) from steel fish
tape/rope connection, secure a swab to rope (use
mop heads or bundle of rags for swab).
4. Pull end of fish tape from starting point through chase
with rope and swab. The swab will sweep clean any
construction materials, moisture, or debris that may
exist in floor chase.
• Chase openings should extend 6" (15.2 cm)
above floor
• Chase must be clean and dry, no foreign materials
Caution: All objects and moisture must be removed from
floor chase before conduit can be routed. It may be necessary to repeat this process to ensure floor chase is clean.
5. After floor chase has been cleaned, remove steel
fish tape and swab from rope. Locate bundle of Multiplex conduit and unspool conduit to allow unrestricted feed during installation process.
6. Locate rope through chase opening and connect to
proper end of Multiplex conduit.
Note: Multiplex conduit is designed to be pulled
through a chase in the direction of arrows printed on
conduit
(refer to figure 2)

7. After rope has been connected, tape end of conduit, including rope, and form conduit end to a point.
Tape will ensure that no contaminants enter conduit
tubes during installation.
8. Place pointed end of Multiplex conduit through chase
opening. While one person pushes the conduit
through chase, another person should be pulling
conduit through chase with rope on opposite end.
FIGURE 2
SEALING INSTRUCTIONS
Aerosol 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.
Note: Please read the manufacturer’s instructions carefully.
9. Once conduit has been routed through chase, pull
enough conduit through openings to ensure an adequate supply at each end of chase for connections.
1. If the opening is too deep, insert a section of the
excess conduit insulation in the opening prior to using
the foam insulation.
2. Make sure all exposed carbonated water and syrup
lines are well insulated: towers to conduit; conduit
junctions, remote unit to conduit; drive thru junction.
Note: A little extra time spent doing a professional job
initially will eliminate a call back in several days to make
corrections.
OVERHEAD INSTALLATION
3. Use aluminum foil (if used), and tape, packed in the
inner pack carton to insulate these connections.
4. Cut the conduit sections to fit like a glove over the
exposed lines and fittings.
Warning: Do not inject foam material directly on the
connections where the tubing connects to the barb
fittings.
FIGURE 3
1. Determine the correct location for routing Multiplex
conduit. Be sure to avoid heat ducts, hoods, grills,
or any sharp objects that may exist above drop ceiling tile.
2. Unspool Multiplex conduit to allow unrestricted feed.
3. Conduit hangers should be spaced no more than 6
ft centers
Once conduit has been routed, ensure an adequate supply of conduit is provided at each end to make all connections
(refer to figure 3)
4. Route conduit above ceiling tiles and connect to ceiling and/or pipes using the appropriate conduit hangers. Be sure conduit is suspended above ceiling tiles.
Concern should be given when determining appropriate method of hanging conduit securely. Hangers must not crush or pinch insulation. This will reduce cooling efficiency.

INSTALLING THE CONDUIT KIT
Connections preview
Review Figures 6, 7 and 8 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:
To insure 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.
Up to eight (8) line conduit:
• six (6) beer maximum, one (1) glycol circuit (two [2] lines)
Ten (10) and over line conduit:
• two (2) glycol circuits (four [4] 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 (see Figure 9).
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 Figure 10).
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 (see Figure 10).
FIGURE 9
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.

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 Figure 11).
2. Attach the opposite end of each 1/2" John Guest
unions to the 1/2" adaptors located at the base of
the dispensing tower (see Figure 11).

BEERMASTER BEER CONDUIT
INSTALLING THE CONDUIT KIT
FIGURE 11
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 attaching two (2)
1/2" John Guest elbows to one another by means of a 2" length of 1/2" tubing.
BEER RESTRICTOR LINES
1. Cut each restrictor line to the calculated length and
carefully insert the 3/16" Barb x 1/2" John Guest
adaptor and clamp securely with the adjustable
clamps provided (see Figure 11).
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 adaptor 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 Figure 12).
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" con-
nectors at the main beer conduit (see Figure 12).
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).
Caution: To avoid agitation use only straight unions when
splicing beer lines.
