FLOOR CHASES
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
• Chase openings should extend 6" (15.2 cm) above floor
• Chase must be clean and dry, no foreign materials
Pulling Conduit Through Floor Chase
1. Determine the most convenient way of routing conduit,
2. Locate steel fish tape and route through chase opening.
3. Locate an appropriate length of rope and tie to end of fish
4. Pull end of fish tape from starting point through chase with

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 co nduit,
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.
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.

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.
Please read the manufacturer’s instructions carefully.
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.
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.
NOTE: A little extra time spent doing a professional job
initially will eliminate a call back in several days to make
corrections.
Do not inject foam material directly on the connections where
the tubing connects to the barb fittings.
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.
(refer to figure 3)
2. Unspool Multiplex conduit to allow unrestricted feed.
3. Conduit hangers should be spaced no more than 6 ft
centers.
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.
Once conduit has been routed, ensure an adequate supply
of conduit is provided at each end to make all connections.

BASEMENT CONSTRUCTION
1. Uncoil Multiplex conduit to allow unrestricted feed
during installation process.
2. Route the conduit up basement wall and secure with
appropriate conduit hangers.
Don't crush or pinch conduit insulation with hangers.
3. Conduit hangers should be spaced no more than 6 ft centers
How To Connect The Multiplex Conduit
NOTE: Conduit lines should be long enough to allow
adequate work space when servicing equipment.
All Multiplex conduit syrup lines, carbonated water lines,
and the plain water line are coded for quick identification
and easy installation.
Only an approved cutting tool should be used to cut
polyethylene tubing. Use a new blade so that the tubing will
not be crushed when cutting.
1. Locate the lines of Multiplex conduit routed at
refrigeration unit and dispensing tower.
2. Using an approved razor knife, cut Multiplex conduit
insulation by slicing along top side while peeling
insulation back at the same time.
3. For soda systems, connect each syrup line, carbonated
water line, and plain water line to the appropriate stainless
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.
Once conduit has been routed, ensure an adequate
supply of conduit is on hand to make all connections.
steel coil in refrigeration unit. For Glycol systems,
connect to bulkhead fittings.
NOTE: Stainless steel cooling coils in our refrigeration units
may contain either barb fittings or John Guest fittings,
depending on model. Before connecting conduit, identify
whether the conduit is thick wall or thin wall tubing (see
illustration). Thick wall tubing should only be used with barb
stem fittings. John Guest fittings can only be used with thin
wall tubing
When suspending Multiplex conduit with conduit hangers, the maximum allowable distance b etween hangers is 6 ft (1.82 m) .
If ambient temperature of the conduit location is 90ºF (32.2ºC) or above, double insulated conduit must be utilized.
Current conduit tubing is PTE lined. Therefore it is no
longer necessary to make sure pungent flavors are used
with specific tubing. Keeping with that process, when
connecting conduit to syrup boxes and valves, the best
flavor/tubing selection would be to utilize line number S1
for valve number 1, S2 for valve number 2, etc.
