3.5. Power Cord / On-Off Switch
Replacement
3.5.1. Removal
1. Remove the dust cover and switch cover to expose the
electrical connections of the power cord, on-off switch and
wire cord.
2. Pull the power cord into the dust compartment in order to
remove the strain relief (for power cord replacement) by
prying or cutting, remove the wire connections, and wire tie,
if present.
3. Remove the on-off switch (for on-off switch replacement) by
depressing the retaining tabs while pushing up and out of
the dust compartment at the same time.
4. Pull the power cord out of the dust compartment (for power
cord replacement).
3.5.2. Installation
1. Insert the new power cord (power cord replacement only)
into the dust compartment as far as necessary in order to
place a new cord retainer in proper location on power cord.
The proper location is approximately one and one eighth
inches/thirty millimeters (1 1/8”/30 mm) of new power cord
outer jacket extending past the cord retainer and washer.
The washer goes between the cord retainer and the dust
compartment. Attach wires with wire connectors according
to the wiring diagram in the front of this manual. ONLY USE
A NEW CORD RETAINER, DO NOT REUSE A CORD
RETAINER.
2. For switch replacement only, insert the new ON/OFF switch
with the numbers 1,2,3, facing toward you, into the dust
compartment until secured by the retaining tabs. Use a wire
tie in the location illustrated taking care not to overtighten it.
Tuck the wire connectors back into the dust compartment
as illustrated in the close-up view.
3. Ensure that the insulator packing is installed correctly.
4. Replace the switch cover, the two (2) switch cover screws,
and the dust cover. Care should be taken not to pinch wires
and make sure that the switch cover goes on easily and
stays flat. If there is resistance to the switch cover lying flat
and in place, stop, remove the cover and make sure that no
wires are being pinched. DO NOT USE A POWER
SCREWDRIVER TO SECURE THE COVER.
NOTE: For general servicing, it is necessary to eliminate
pinching of any wire during reassembly. After servicing
any electrical component or electrical enclosure, the unit
should
be
reassembled
and
checked
for
dielectric
breakdown or current leakage.

pressing it into place until the tabs are securely locked into
the dust compartment.
