Suggested Installation Equipment (not supplied with kit)
• Cable preparation tools
• Raychem P63 cable preparation
kit or cable manufacturer approved
solvent
• Clean, lint-free cloths
• Non-conducting abrasive cloth,
120 grit or finer
• Electrician's tape
Recommended Raychem Torches
Install heat-shrinkable cable
accessories with a "clean burning"
torch, i.e., a propane torch that
does not deposit conductive
contaminants on the product.
Clean burning torches include the
Raychem FH-2629 (uses refillable
propane cylinders) and FH-2616A1
(uses disposable cylinder).
Safety Instructions
General Instructions
• Connector(s) and installation tools
• Raychem recommended torch
Warning: When installing electrical
power system accessories, failure to
follow applicable personal safety
requirements and written installation
instructions could result in fire or
explosion and serious or fatal
injuries.
Adjusting the Torch
Adjust regulator and torch as
required to provide an overall 12inch bushy flame. The FH-2629 will
Cleaning the Cable
Use an approved solvent, such as
the one supplied in the P63 Cable
Prep Kit, to clean the cable. Be
sure to follow the manufacturer's
instructions. Failure to follow these
instructions could lead to product
failure.
To avoid risk of accidental fire or
explosion when using gas torches,
always check all connections for
leaks before igniting the torch and
follow the torch manufacturer's
safety instructions.
To minimize any effect of fumes
produced during installation, always
provide good ventilation of confined
work spaces.
be all blue, the other torches will
have a 3- to 4-inch yellow tip. Use
the yellow tip for shrinking.
Some newer solvents do not
evaporate quickly and need to be
removed with a clean, lint-free
cloth. Failure to do so could
change the volume resistivity of the
substrate or leave a residue on the
surface.
As Raychem has no control over
field conditions which influence
product installation, it is
understood that the user must take
this into account and apply his own
experience and expertise when
installing product.

Please follow the manufacturer's
instructions carefully.
General Shrinking Instructions
• Apply outer 3- to 4-inch tip of the
flame to heat-shrinkable material
with a rapid brushing motion.
• Keep flame moving to avoid
scorching.
• Unless otherwise instructed, start
shrinking tube at center, working
flame around all sides of the tube to
apply uniform heat.
PII-51030, Rev AB
DCR C28328
To determine if a tube has
completely recovered, look for the
following, especially on the back
and underside of the tube:
1. Uniform wall thickness.
2. Conformance to substrate.
3. No flat spots or chill marks.
4. Visible sealant flow if the
tube is coated.

Note: When installing multiple
tubes, make sure that the surface of
the last tube is still warm before
positioning and shrinking the next
tube. If installed tube has cooled,
re-heat the entire surface.

1. Prepare cable.
Refer to Table 1 and prepare the
cables as shown. Remove any fillers
to the armor cutback. Bend back the
grounding conductors(s) over the
jacket as shown.
2. Clean cables.
Using an approved solv ent, clean the
cables as shown.
Note: An armored cable is used as
an example. All instructions apply to
both armored and unarmored cable
unless otherwise stated.
3. Place tubes over phases.
Place one black sealing tube over
each phase as shown (on long side).

5. Position blac k sealing tubes;
shrink in place.
Make sure each tube is centered ov er
the connection area. Shrink all three
tubes in place at the same time.
Begin shrinking at center of tubes (1),
working torch with a smooth, brushing
motion around the tubes. After center
portion shrinks, work torch as before
toward one end (2), then to the
opposite end (3).
Note: Do not point the flame directly
at the cable insulation.
6. Connect grounding conductor.
Bend the grounding conductor(s)
back over the tubes and splice with a
suitable connector .

7. Install armorcan.
Center armorcan over splice, equally
overlapping the exposed armor on
both sides.
Tape the shells together in the center.
Pull the aluminum fingers down on
the bare cable armor and tape in
place.
Clean the cable jackets as shown.
8. Position wraparound sleeve.
Remove or tape over all sharp points
to prevent puncture of wr aparound
sleeve .
Remove backing from the wraparound
sealing sleeve and center sleeve over
splice. Slide metal channel(s) onto
the butted rails.

If two channels are used, connect the
channels with the short channel
retention clip. Use pliers to install
clip.
Note: Channel(s) must overlap
sleeve edge by 1/4"

minimum.
10. Shrink the wraparound sleeve.
Begin shrinking at the center and
work toward each end. Post heat the
entire sleeve (concentrating on metal
