Heating Cable Installation
Raychem-IM-H57548-HWATsystem-EN 16/08
Attaching the heating cable
Starting from the end opposite the reel, tape the
heating cable to the pipe every 2 feet. Work back to
the reel. Leave extra heating cable at the power con-
nection, at all sides of splices and tees to allow for
future servicing. See Table 1 on page 15.
• Install heating cable connection kits immediately
after attaching the heating cable. If immediate
installation is not possible, protect the heating
cable ends from moisture.
Bending the cable
When positioning the heating cable on the pipe, do
not bend tighter than 1/2” radius. The heating cable
does not bend easily in the flat plane. Do not force
such a bend, as the heating cable will be damaged.

Crossing the cable
HWAT heating cables are self-regulating and may be
overlapped whenever necessary without overheating
or burning out.
Cutting the cable
Cut the heating cable to the desired length after it
is attached to the pipe. HWAT can be cut to length
without affecting the heat output per foot.
Attachment tapes
To ensure that the heating cable is in full contact
with the pipe, use tape to attach the heating cable
to the pipe every 2 ft (.6 m). Use Raychem GT-66
attachment tape. One roll will handle approximately
50 ft (15 m) of cable.
