Safety Guidelines
As with any electrical equipment, the safety and reliability of any system depends on the
quality of the products selected and the manner in which they are installed and maintained.
Incorrect design, handling, installation, or maintenance of any of the system connection kits
could damage the system and may result in inadequate performance, overheating, electric
shock, or fire. To minimize these risks and to ensure that the system performs reliably, read
and carefully follow the information, warnings, and instructions in this guide.
This symbol identifies important instructions or information.
This symbol identifies particularly important safety warnings that must be followed.
WARNING: To minimize the danger of fire from sustained electrical arcing if the
heating cable is damaged or improperly installed, and to comply with the requirements of
Tyco Thermal Controls, agency certifications, 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.
