Step 4: Route the cold lead
Position the cold lead of the mat as close as possible to the
wall near the electrical junction box. The cold lead must be
routed outside of the heating mat, never under or over the
heating cable and must not protrude higher than the heat-
ing mat.
If the splice is higher than the mat, you must gouge out
the sub floor to allow the splice to lay flat under the tile.
Run the cold lead inside the wall to the electrical junction
box location.
Important: Position the cord label on the cold lead
inside the electrical junction box. If it is necessary to
shorten the cold lead, be sure to store the cord label in
the junction box.
Figure 9: Routing the cold lead
Step 5: Place the floor temperature sensor
Center the floor temperature sensor between two runs of
the heating cable, 4 inches from the end of the heating
cable loop (see Figure 10). Run the floor temperature sen-
sor inside the wall to the electrical junction box location.

Figure 10: Placing the floor temperature sensor
Important: Do not allow heating cable, cold lead,
or floor temperature sensor to cross over themselves or
each other.
Note: When installing a 240 V QuickNet mat with an
Extension mat to accommodate a floor over 100 ft
only one floor temperature sensor and one thermostat to
control both mats.
Step 6: Perform Insulation Resistance Test, Heating
Cable Resistance Test, and the Sensor Resistance Test
(Before embedding in mortar)
Important: You must perform the insulation resis-
tance test, heating cable resistance test, and the sensor
resistance test before you embed the mat in mortar to
confirm that the heating cable and floor sensor have not
been damaged. For information on how to perform these
tests, see Section 7, Commissioning. Record the results
in the Commissioning Record in Section 9.
Important: After layout is complete, take a picture of
the layout for future reference.
