IMPORTANT: Please read all instructions

before beginning.

IMPORTANT - PLEASE READ ALL INSTRUCTIONS BEFORE BEGINNING.

SAVE THESE INSTRUCTIONS FOR REFERENCE AND ADDITIONAL WORK REQUIRED

AFTER CONCRETE POUR.

General:

Review and become familiar with all Walkercell components. Be careful of sharp edges or burrs when
handling any sheet metal parts. All interior surfaces that can be touched by a wire shall be smooth.

Compare and coordinate the architectural and electrical drawings with the Wiremold installation drawings.
Contact your local Wiremold field sales representative immediately if any dimensions or details are incorrect.

Install Walkercell and related components in accordance with Article 356 of the latest issue of the National
Electrical Code. Keep material and cartons dry. Advise all trades that Walkercell is not to be used as a walkway
or crosswalk.

Provide a vapor barrier when duct is installed directly on grade. This barrier prevents ground moisture from
reaching the underside of the concrete slab through capillary action.

Laying Out the System:

Refer to the installation drawings to locate the position of the Headerducts and Junction Boxes. Strike a base line
to correspond with the center of all runs.

Use either bench marks on walls or columns or a laser type system to level the system.

The complete header systems (including risers) should be installed before installation of the Walkercell is begun.

Installing the Headerduct:

The Headerduct is furnished with a coupling strap that creates a male/female relationship. At the electrical or
communications room the Headerduct will have the male end exiting the room. Position the next piece of Headerduct
by sliding the female end of the piece to be positioned onto the male end of the Headerduct exiting the room. Using
the adjusting feet, secure the Headerduct to the form with nails, screws, or other suitable fasteners. Adjust to level.
Secure the coupling support across the top of the Headerduct with the screws provided.

CBR-HT (Cell Boot Riser – Power):

The cell boot riser can be used for either Headerduct or Walkercell. Position the cell boot directly below the future

ocation of the power panel. Field drill a 2 1/2" x 6" [64mm x 153mm] oval hole to fit within the cell boot. Install an

l
H14-PSR-1.4 grommet. Pop rivet or weld the cell boot to the raceway. Install the riser sleeve and terminal bushing
at the same time as installing the power panel.

CBR-LT (Cell Boot Riser – Communications):

The Cell Boot Riser for communications, installs similar to the CBR-HT with the exception that power terminates
approximately 3" [76mm] to 4" [102mm] above the finished floor. When used on Walkercell, void closures must
be installed to prevent entry of wet concrete during pours.

45° Vertical Elbow:

Position the 45° vertical elbow directly below the future cabinet or panel location. Attach the vertical elbow to the
Headerduct, using the coupling channel centered across the top of the Headerduct and 45° vertical elbow. Use the
screws provided with the coupling channel.

NOTE: The Headerduct has male and female ends. Attach the vertical elbow at the female end. Use the adjusting feet to adjust the Headerduct

to its proper height. Secure the Headerduct to the form with the proper fasteners.

CBR-LHT (Cell Boot – Power and Communications):

The CBR-LHT can be used when all three services must enter from one opening. It terminates approximately 3" [76mm]
to 4" [102mm] above the finished floor. The riser sleeve and terminal bushing should be installed during the installation
of the power panel.

Installing Header Junction Boxes:

Junction Boxes have openings for Headerduct and may have one opening for Walkercell raceway. Adjust the
Headerduct Junction Box to the correct level. The Headerduct that attaches to the junction box should be resting on
the support ledge. Secure the adjusting feet to the form. Adjust the Headerduct adapters so that the adapters rest on
top of the Headerduct. Secure the set screws in the side of the adapters to complete coupling the Headerduct to the
Headerduct Junction Box.

Installing Junction Boxes:

Walkercell Junction Box Headers are very similar to the Header Junction Boxes except they will always have one or
two openings for the Walkercell Raceway. Each Junction Box has a male and female end. Position the Junction Box
by sliding the male or female end into the correct mating end of the Header Junction box or another Junction box.
Secure the Junction box adjusting feet to the form. Secure the coupling channel across the top of the Headerduct
with the screws provided.

Installing Junction Box End Closures: The end closure is a U–Channel that fits over the open end of the Junction
box. Slide the U–Channel in place. Secure with pop rivets or welds.
