DFT Installation Instructions
Routing Cold Lead
It is important to properly de-coil the cable to prevent twisting (see example in Figure 10)�
Using a fish cord, pull the cold lead and sensor wire� Allow at least 6" (150mm) of cold lead and sensor
wire to project from the ECB (Figure 11 shows how)�
DO NOT REMOVE IDENTIFICATION LABEL� If necessary, ID label can be moved on cold leads so that it
remains inside the ECB�
Due to the larger cable diameter of the cold lead splice, remove approximately 3/16" (5mm) of sub-floor
material where the splice will be fastened, to eliminate any possible interference with the tile� Secure the
cold lead splice and tail splice with the plastic clips (shown in Figure 12 below)�

Installing Cable
Place Heating Cable between the tabs and loop around to secure in place (see Figure 13)� Proceed with
cable installation following the Floor Layout Plan, space at intervals of 3" (3 tabs) for Standard Heating
Cable Spacing (as shown in Figure 14) and every 3" - 2" - 3" - 2" (3-2-3-2 tabs) for Alternating Heating
Cable Spacing (as shown in Figure 15)�
Apply sucient tension to the cable so that it is tightly secured around the tabs�
The cable loop should not extend beyond 1/2" (13mm) from the outside edge of the strapping�
NOTE: HEATING CABLE MUST BE INSTALLED IN THE STRAPPING IN THE MANNER DESCRIBED�
FAILURE TO DO SO MAY RESULT IN IMPROPER SYSTEM OPERATION�
