Raychem WinterGard self-regulating heating cables provide
convenient, reliable freeze protection for a wide variety of pro-
fessionally installed residential and commercial water-pipe and
roof-and-gutter de-icing applications in nonhazardous areas.
This data sheet is designed to assist in cable and accessory
selection and basic circuit design of pipe-freeze-prevention
applications.
Complete design guidelines, installation instructions, and safety
information are provided in the Commercial and Residential
Self-Regulating Heating Products Application and Design Guide
(H53585), the H900 Power Connection Kit, the H908 Plug-in
Power Connection Kit, and the H921 120-V ground-fault protect-
ed junction box.
For detailed information on roof and gutter de-icing applica-
tions, please refer to the WinterGard Wet Design, Installation
and Maintenance Guide (H56804).

Pipe Applications
WinterGard systems must be installed correctly to
ensure proper operation and to prevent shock or
fire. Carefully read and follow the Commercial and
Residential Self-Regulating Heating Products
Application and Design Guide and the H900 series
connection kit installation instructions.
• Use only in ordinary (nonhazardous) areas. Do not
expose to any chemicals, oil or grease.
• In wet areas, use only WinterGard Wet.
• To minimize the danger of fire from sustained elec-
trical arcing if the heating cable is damaged or
improperly installed, and to comply with the
requirements of Pentair Thermal Management,
agency approvals, and national electrical codes,
ground-fault equipment protection must be used
on each heating cable branch circuit. Arcing may
not be stopped by conventional circuit protection.
• This selection guide does not take the place of the
installation instructions included in the
Commercial and Residential Self-Regulating
Heating Products Application and Design Guide and
in the H900 series accessory kits.
• System approvals and performance are based on
the use of only H900 series accessories with
WinterGard heating cables. These accessories
must be used. Do not substitute parts.
