○
remove the access panel from the rear of the blower box module.
○
route the harness from the rear of the lower electrical box of the main
electric harness to access the hole on the side of blower box.
○
match and connect the harness connectors "b" inside the lower electri-
cal box and snap the flex conduit connector into the side of the electrical
box.
○
wires from the other end of the harness should pass through the hole
in side of the blower module. The 90° flex connector should also be
passed through and secured by the connector nut on the inside of box.

○
The length of "b" harness has been made to allow for instal-
lation of an electric furnace module (Hmfk-ef15/18/20/25).
if electric furnace module is not being installed, the length
of flex conduit needs to be reduced by 12" (305mm). Re
-
move the 90° bulk head connector from end of flex conduit,
slide the liner off wires far enough that the wiring will not be
damaged when adjusting the length of flex conduit. Mea
-
sure 12" (305mm) off end of the flex conduit and put small
break/kink in the conduit at this point using side cutters or
hacksaw blade. The conduit can then be flexed back and
forth over this break until it breaks completely apart, and the
12” (305mm) section can be removed. feed the wires back
through the flex conduit and relocate the 90° head connector
bracket to the new end of the flex conduit.
○
Copy the wire, marking number, located near the end of each
wire, onto a piece of masking tape and stick this marker 14"
(355mm) away from wire end. The wire can now be short-
ened by 12" (305mm).
