Install Instructions
List of Components
The following components are included in your in-line pipe heating cable kit:
• heating cable pre-assembled to T-coupling **Warning: The heating cable
has been pre-assembled and sealed to the T-coupling at the factory – do
not adjust these connections as damage to the T-coupling, cable and/or
seal may occur.
• stainless steel end connector clip.
• power control enclosure (SL1-G or SL2-G), includes thermostat and GFCI
receptacle.
• two tie-wraps (to attach thermostat sensor to pipe).
The longer lengths of heating cables are supplied on a convenient spool.
DO NOT REMOVE THE HEATING CABLE/T-COUPLING FROM THE CABLE
SPOOL.
In addition, you will require insulation and protective covering (to reduce wind chill
effect) for any exposed areas of pipe, an assortment of tools (e.g. electrician’s
sh tape), plumbing supplies, etc., depending on your specic installation.
Preparation for Installation of Heating Cable
This heating cable has been designed to prevent water supply pipes from
freezing. It is expected that the cable will be entirely inserted into either 1” or
1
1
/4” diameter, buried and/or insulated, polyethylene water piping. In addition,
if the cable is being installed in a pressurized pipe, it is recommended that
the maximum system pressure be less than 60 psig. The heating cable life
expectancy can be extended if the cable is installed in non-pressurized piping.
For example, the installation of a check valve at the suction port of a jet pump
will ensure that the suction piping is not pressurized; hence, a heating cable in
the suction piping will not be subjected to system pressure.
The heating cable inside the pipe should extend beyond the furthest point of
the pipe, which would, if unheated, be expected to freeze in winter. The pipe
itself can, if necessary, further extend beyond the end of the cable. Refer to
Figure A.
It is not possible to alter the length of the cable to accommodate a nonstandard
length of piping. These heating cables are available in a wide variety of standard
lengths; ensure that the cable you have chosen for your installation is of
appropriate length.
