Installation

Duct Proofing

Use appropriate seal-off kit
(Reference pg. 9 for Line
Blowing Kits). For maximum
line blowing potential, use
air compressor at 175 CFM
(125 PSI Max.)

1.

Slide pull line through
opening in threaded
nozzle end of seal-off.
Attach blowing missile
to pull line.

2.

Insert blowing missile
into individual duct and
insert threaded end of
seal-off into duct to
assure minimal air loss.

3.

Attach seal-off to air
compressor with air
release lever in off
position. Hold seal off
firmly in hands.

4.

Open lever quickly
making sure slight tension
is on to prevent pull line
from packing. CAUTION
SHOULD BE EXERCISED
AT THE EXIT POINT FOR
MISSILE TO AVOID INJURY.
Blow pull line in all ducts
to ensure no blockages are
present.

Installation Instructions

When handling Intra-Gard®, care must be taken to avoid
striking the ends against hard surfaces. This can cause damage
from impact or crushing of the end of the conduit.

Assembly In Trench

1.

In the trench, set the first layer of ducts by inserting the male
ends into the female ends on the sections previously placed.
Remove the protective caps as the sections of pipe are about to
be joined together, and make sure the matching colors are aligned.

2.

A thin coating of Carlon
Quick Set Cement should
be applied to the inside
surface of the sockets
lightly enough to pre­vent the formation of a
bead of cement at the
interior shoulder of the
sockets. Then, apply in
the same manner to the
spigot ends of the con­duits to the depth of the
socket.

3.

Immediately after apply­ing the coat of cement
to the conduit, insert the
spigot ends into the
sockets.

Field Cuts

Joining a Male/Female Connection

1.

The pipes should be laid side by side and the
male end marked at the base of the bell on the
female end.

2.

Make a straight through cut on the male end
using a standard carpenter’s saw. Deburr the
ends of the cut pipe.

3.

Apply Carlon Quick Set Cement in a thin uni­form coating to the inside surface of the sock­ets and raise both ends and align the ducts on
the male ends to the bells on the female end.

4.

Once the ducts are aligned with their sockets,
lower both of the pipes. The ducts will be auto­matically returned to their original position as
the joints are forced together.

Field Cuts

Repairing Damaged Intra-Gard That Is Vacant

1.

Cut out damaged section making a flush cut on
both sides and deburr all pipes.

2.

Measure damaged section and new section
wIth a socket and measure from base of socket
and cut flush. Intra-Gard couplings are installed
onto the individual ducts of the section in the
ground.

3.

Install new section in trench by first applying
Carlon Quick Set Cement and pushing sockets
onto either spigot ends.

4.

Line up ducts with couplings and raise or bow
center of duct span, apply cement and slip
ducts into couplings.

Repairing Intra-Gard

®

Once Installed

Joining Two Male Ends

1.

The pipes should be laid side by side, marked and flush cut
to butt up against each other. Deburr the ends of the cut
pipe and install a spare spacer if needed, and use standard
couplings.

2.

Place each individual coupling onto ducts using Carlon
Quick Set Cement.

3.

Lift sections to align each coupling with other ducts.

4.

Lower both sections to a level position.

Repair sections may use a standard 20' length of
lntra-Gard with sockets and cut to length.

Repairing Intra-Gard Housing a Cable

1.

Carefully cut out the damaged section of the Intra-Gard.

2.

Where cable is installed, slide the split couplings onto
each individual duct, fitting the cable into the grooved
coupling passage. Repeat the process on the other side.

3.

Carefully insert the cable into the split duct. Push the
split duct into the split coupling at both ends. Wrap all
slit areas with sealing tape or shrink wrap, etc. as rec­ommended by specifier to seal out water.

4.

Install stop coupling onto other vacant ducts with
Carlon Quick Set Cement and install the ducts into the
other openings of the couplings with cement.

5.

Ensure the duct system is straight and even before
encasing in soil.
