Terminate Blower Power Cable - Remote - Kohler K-723 Installation Manual

10. Terminate Blower Power Cable - Remote

Route the Blower Power Cable
Route two conductors with ground 18 AWG or equivalent power cable (not supplied) between the
bath and blower motor locations. Follow all applicable electrical and fire codes. Ensure that the
cable jacket meets applicable code requirements and the cable is properly supported and protected.
Prepare the Blower for Remote Installation
Loosen the cable strain-relief nut on the blower motor. Push the nut back on the cable to provide
clearance for removal of the cover.
Remove the two access cover screws from the back of the blower motor. As you are loosening the
screws, check periodically if the cover can be slid back on the electrical cable.
When the cover is loose, use electrician pliers or equivalent to cut the electrical cable at a point
about 4" (10.2 cm) from where the cable disappears into the blower motor housing.
Pull the free end of the electrical cord through the cover, insert, and strain relief nut.
Discard the existing strain relief nut and insert.
Reconnect the blower motor plug to the control.
Install a standard NPT threaded strain relief to the blower motor cover.
Temporarily store the removed components in a safe location.
Terminate the New Power Cable at the Blower Motor
At the blower motor 4" (10.2 cm) pigtail lead, strip back the cable jacket about 3" (7.6 cm).
Using a wire nut, cap off the unused brown conductor in the cable jacket.
At the newly installed blower motor power cable, strip back the cable jacket about 2" (5.1 cm).
For installations in the United States, mark any white conductors with red or black tape as required
by the NEC.
Strip the wire insulation about 3/8" (1 cm) from the blower motor pigtail leads and from the power
cable leads.
Route the new power cable leads through the blower motor access cover and strain relief.
Using wire nuts or other approved termination methods, terminate the conductors as follows:
• Connect the black pigtail lead to the L1 conductor of the power cable.
• Connect the blue pigtail lead to the L2 conductor of the power cable.
