Power Cord / On-Off Switch
Replacement
3.7.1.
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).
3.7.2.
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 connec-
tors 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 over-
tighten 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 pinch-
ing of any wire during reassembly. After servicing any electrical
component or electrical enclosure, the unit should be reassem-
bled and checked for dielectric breakdown or current leakage.
