WarmlyYours TempZone Floor Heating Cable (Twin) - Manual (Page 18)

Installation and Operation SECTION 5
5.5.2 Install the TempZone™ Floor Heating Cable (Twin)
1. Begin installing the heating cable from the thermostat or junction box. Follow the pattern marked on the floor plan (if
supplied). Please note the thickness of the factory splice and cold lead and plan accordingly.
2. Unwind the cable from the spool. Secure it using the TempZone™ Cable Fixing Strips. Avoid bunching the cable or
crossing over other parts of the cable.
3. The TempZone™ Floor Heating Cable (Twin) should be installed in a uniformly-spaced serpentine pattern. Refer to
either “Product Selection Guide--120V” or “Product Selection Guide--240V” in section 9 for spacing information.
4. Take note of the cable’s halfway point marking indicated on the cable. This mark should match the halfway point
indicated on the custom SmartPlan™ supplied with the order (optional).
5. Route the power leads from the floor to the thermostat box. If using multiple heating cables, route the power leads from
the floor to a junction box or thermostat box in the wall.
NOTE: Leads should be protected at the point they leave the floor. Rigid metal conduit, intermediate metal
conduit, rigid nonmetallic conduit, electrical metallic tubing, or other means approved by local electrical codes
should be used.
6. For installations including a thermostat, the low-voltage floor sensor should be placed
in between the loops created by the cable and held in place with a small amount of
thinset or hot glue. See Figure 7.
The sensor wire cannot cross any heating cable or lead wire. It must extend at least 6
inches into the heated area. The sensor and its wire should be covered directly with
thinset or self-leveling underlayment.
The cold lead wires should be placed above the subfloor, along the side of the heated
area at least 2 inches from the heating wire. Secure the cold lead wires with a suitable
tape or hot glue before the thinset or self-leveling underlayment is applied over the
cables.
7. Use an ohmmeter or the ohms testing function of PowerMan™ to check the continuity, insulation resistance, and
resistance values again after the cable has been installed. Compare these post-installation values with pre-installation
values to ensure they are consistent. Record post-installation values on the warranty card in section 10.
Attach Circuit Check™ or PowerMan™ to cold leads at this time. Refer to section 5.3 and 5.4 for instructions. Set the
PowerMan™ to the “OHMS” setting to check resistance. After checking resistance values, set the PowerMan™ to the
“CIRCUIT CHECK” setting to begin installation.
