Materials for one power connection and one end seal are included. All WinterGard heating cables are designed for water-pipe freeze protection applications. Only the H612 and H622 cables can be used for both pipe freeze protection and roof and gutter de-icing applications. Do not use this kit with aluminum feed wires. For additional technical support call Pentair Thermal Management at (800) 545-6258. Note: For WinterGard heating cables in pipe heating applications, refer to pages 3–5. For WinterGard Wet heating cables H612 and H622 in roof and gutter de-icing applications, refer to pages 6–8. TOOLS REQUIRED • Needle nose pliers • Pen • Propane torch or heat gun • Diagonal cutters • Utility knife • Panduit CT100 crimp tool • Adjustable wrench • Screwdriver ADDITIONAL MATERIALS REQUIRED • UL Listed or CSA Certified junction box suitable for the location, with a clearance hole for 1/2-inch conduit or 1/2-inch NPT threaded hub. • For H311, H611, and H621, you must use a metallic junction box to ensure proper grounding. • Your application may require additional WinterGard accessories; for example, H903 application tape for pipe applications; H913/ H914 roof clips and/or H915 downspout hangers for roof and gutter de-icing applications. These components are electrical devices. They must be installed correctly to ensure proper operation and to prevent shock or fire. Carefully follow all of the installation instructions and read these important warnings. • 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 Pentair Thermal Management 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. • Component approvals and performance are based on the use of specified parts only. Do not substitute parts or use vinyl electrical tape. • The black heating-cable core is conductive and can short. It must be properly insulated and kept dry. • Keep components and heating cable ends dry before and during installation. • Damaged bus wires can overheat or short. Do not break braid or bus wire strands when scoring the jacket or core. • Bus wires will short if they contact each other. Keep bus wires separated. • Heat-damaged components can short. Use a heat gun or a torch with a soft, yellow, low-heat flame, not a blue focused flame. Keep the flame moving to avoid overheating, blistering, or charring the heat-shrinkable tubes. Avoid heating other components. Replace any damaged parts. • Use only fire-resistant insulation materials such as fiberglass wrap. • Leave these installation instructions with the user for future reference. Charring or burning the heat-shrinkable tubes in this kit will produce fumes that may cause eye, skin, nose, and throat irritation. Consult Material Safety Data Sheet RAY3122.

Important: For the Pentair Thermal Management warranty to be valid,youmustcomplywithalltherequirementsoutlinedintheseguidelines.
Allthermalanddesigninformationprovidedhereisbasedupona“standard” installation with heating cable fastened to an insulated pipe. For any other application or method of installation, consult Pentair Thermal Management at (800) 545-6258.
HEATING cAbLE SELEcTION AND DESIGNMake sure that the heating cable being used is suitable for your application.RefertotheCommercialandResidentialApplicationandDesign Guide (H53585) for heating cable application information.
1. Determine the heating cable type.UseTable1toselectheatingcablesforinsulatedmetalpipes.UseTable2toselectheatingcablesforinsulatedplasticpipes.Readacross the table to find your pipe size, then drop down to the line corresponding to the lowest air temperature for that application and the correct insulation thickness. The cell at that intersection has a particularshadingandmayhaveanumber.Theshadingindicateswhichheatingcabletouse(keytotheshadingappearsabovethetableheadings). A number represents the spiraling ratio (feet of heating cable per foot of pipe).
If no number appears in the cell, straight trace the pipe. If a number does appear in the cell, spiral trace the pipe.
If your spiraling ratio is 2.0, multiple trace the pipe using two straight traces at the 4 o’clock and 8 o’clock positions.
If your spiraling ratio is 3.0, multiple trace the pipe using three straight traces at the 11 o’clock or 1 o’clock position, and at the 4 o’clock and 8 o’clock positions.

HEATING cAbLE TESTING AND MAINTENANcE
Pentair Thermal Management recommends that the insulation resistance between the bus wires and the heater grounding braid or metal pipe should be checked during installation using a 2500-Vdcmegohmmeter.Minimumreadingshouldbe1000megohms,regardless of length.Recordtheoriginalvaluesforeachcircuit.Takeadditionalreadingsduring regularly scheduled maintenance and compare to the original value.Ifthereadingsfallbelow1000megohms,inspectcablesandinsulation for signs of damage.

Pentair Thermal Management recommends that the insulation resistance between the bus wires and the heating cable grounding braid or metal pipe should be checked during installation using a 2500-Vdcmegohmmeter.Minimumreadingshouldbe1000megohms,regardless of circuit length.
Recordtheoriginalvaluesforeachcircuit.Takeadditionalreadingsduring regularly scheduled maintenance and compare to the original value.Ifthereadingsfallbelow1000megohms,inspectheatingcablesand insulation for signs of damage.
If physical damage is found, the entire damaged section must be removedandanewsectionofheatingcablesplicedinusingonlyapprovedWinterGardH910splicekits.Donotrepairthedamagedheating cable section.
If physical damage cannot be found, the complete circuit should be removedandreplacedwithnewWinterGardheatingcable.
WARNING: Shock and Fire Hazard. Damaged heating cable or components can cause electrical shock, arcing, and fire. Do not attempt to energize damaged cable or components. Replace them immediately using a new length of heating cable and the appropriate WinterGard accessories.
