LOOP INSTALLATION
1. Layout the desired loop locations per the diagram.
The standard size chart below will give an
approximate length of wire required for various loop
dimensions and number of turns required.
CAUTION:
The Loop wires and Lead-in wires must be a
continuous piece of wire without splices. Only use wire
intended for this type of application. (Type XHHW
insulation 16AWG)
NOTE:
Buried steel from drains or other systems may affect
functioning of the loop system. Check with the factory for
advice on any special installations.

2. Cut the required groove as shown in the diagram below
at the locations laid out in
Step #1.
3. Leaving enough wire for the
LEAD IN,
insert the
specified number of turns of wire in the cut grooves.
(See chart).
CAUTION: Be careful not to damage the wire
insulation during installation.
4. After completing the required number of loop turns,
twist the ends together at the rate of
6
turns per foot to
form the
LEAD-IN.
5. Seal the
LEAD-IN
wire in the conduit to prevent
moisture seepage into the conduit.
