Installing the induction coil
(continued)
9. Installing the induction coil on copper pipe will need a double layer coil. Wrap the first layer coil as men-
tioned on the previous page.
10. When finished wrapping the first layer and securing to the pipe with a cable tie, then another layer of
wrapping must be applied on top of the first layer of wrappings with the remaining wire.
11. The second layer of wrappings must be wrapped with the same rotation as the first layer of wrappings (if
the first layer is clockwise then the second layer must be clockwise also or if the first layer is counter clock-
wise then the second layer must be counter clockwise also).
12. When the second layer is complete secure the wire down to the pipe with a cable tie (both wire leads will
exit on the same end of the induction coil).
Note: Keep induction coil far away as possible from elbows,
tees and couplings and never wrap coil on top of any fitting.
