2.2 Important Electrical Precautions Before Installation
IMPORTANT: Where required, all electrical connections should be performed by a licensed, certified electrician in
accordance with local and national electrical code requirements.
2.2.1 TempZone™ Floor Heating Cable (Twin) has an earth-grounding braid (metal sheath). The earth-grounding braid should be
properly grounded. The core wires should be connected to the main power supply.
2.2.2 Verify that cable voltage matches the voltage of circuit.
2.2.3 Check the ohms resistance of the TempZone™ Floor Heating Cable (Twin) before, during, and after installation. Resistance
value should match the value given on the label attached to the cable. A tolerance of -5/+10% at 20ºC (68ºF) is allowed.
2.2.4 Local electrical codes may require the low-voltage sensor wire to be installed in conduit. If this is required, do not install the
low-voltage sensor lead in the conduit containing the cold leads. Provide a separate conduit for the low-voltage sensor wire.
2.2.5 WarmlyYours strongly recommends connecting the Circuit Check™ or PowerMan™ device to warn of accidental damage to the
TempZone™ Floor Heating Cable (Twin) or lead wires during installation.
2.2.6 TempZone™ Floor Heating Cable (Twin) should be connected to a Listed Class–A Ground Fault Circuit Interrupter (GFCI). If
using one of our programmable or nonprogrammable Listed thermostats that include a built-in GFCI, then a separate Class–A
GFCI is not required.
2.2.7 If the GFCI is tripped during normal operation and cannot be reset, there may be a fault in the cable. Do NOT attempt to re-
energize the TempZone™ Floor Heating Cable (Twin). Do NOT bypass the GFCI under any circumstances. Contact a qualified
electrician or WarmlyYours for assistance.
2.2.8 Indicate which branch circuits or circuit breakers supply the power to the floor heating cable in a convenient location
(e.g. taped to the circuit breaker box) for reference by the electrical inspector or homeowner. Retain the UL labels for each
TempZone™ Floor Heating Cable (Twin). Leave one UL label attached to the floor heating cable.
2.2.9 Use only Listed conduit, fittings, and other components.
2.2.10 TempZone™ Floor Heating Cable (Twin) shall not extend beyond the room or area in which it originates.
2.2.11 The TempZone™ Floor Heating Cable (Twin) should only be installed by qualified personnel who are familiar with the
construction and operation of the TempZone™ Floor Heating Cable (Twin) and the risks involved.
2.2.12 The installation of the TempZone™ Floor Heating Cable (Twin) shall be in accordance with all manufacturer’s instructions and
local and national codes.
2.2.13 In Canada, the installation shall be made according to the provisions of section 62 of the Canadian Electrical Code, Part 1.
2.2.14 When used in wet locations, the installation shall be in accordance with the National Electrical Code (NEC), NFPA-70 and
CAN/CSA-C22.1, Canadian Electrical Code (CEC), Part I. Final approval of the installation is to be determined by the Authority
Having Jurisdiction (AHJ). The UL Listing for this product does not cover use in wet locations in the United States. Installations
shall be in accordance with the National Electric Code, NFPA 70 and any other applicable jurisdictional codes and final
acceptance is to be made by the Authority Having Jurisdiction (AHJ).
WARNING : Risk of electric shock and fire. Damage to supply conductor insulation may occur if conductors are
routed less than 2 in. (51 mm) from this heating product. Refer to installation instructions for recommended
means of routing supply conductors.
