Installation
Cord Replacement
Hazardous voltage. Unplug pump before
working on or servicing pump. Don't attempt to modify
the cord or plug; these instructions are ONLY for
replacement of cord.
1. Unplug the pump.
2. Unscrew the two screws holding the cord plate to
the back of the motor. Pull the cord gently out of the
motor cavity.
3. Cut the existing wires on the motor side of the
crimps, as close to the connectors as possible (in
other words, leave yourself as much wire in the
motor as possible).
4. Strip all the wires back about 5/8" from the wire
ends.
NOTE: Make connections with wire nuts designed
for connecting 2 #16 AWG wires (see the wire nut
package).
5. Connect the green (ground) wire from the cord to
the green (ground) wire from the motor. Connect the
black (hot) wire from the cord to either black wire
from the motor. Connect the white (neutral) wire
from the cord to the remaining black wire from the
motor.
6. After you have made the connections, check all
connections carefully to be sure that no bare copper
shows. If you see any bare wire, disconnect the wire
nut and remake that connection.
7. Once you are sure that there is no exposed wire,
carefully stuff the wire and wire nuts back into the
cavity in the motor.
8. Hold the cord plate up against the motor and
reinstall the screws. Tighten thoroughly but do not
overtighten!
9. Once assembly is complete, SET THE PUMP DOWN
(that is, don't touch it) and plug it in (very briefly,
to avoid damaging the shaft seal) to make sure that
everything is correctly connected and nothing is
shorted.
10. The pump is ready for operation.
Motor Brush Replacement (See Brush Changing
Procedure, page 7:
Replace brushes when they wear down to 3/8" (9.5mm)
length.
1. Unplug pump from power outlet.
2. Unscrew brush caps and remove brushes.
NOTICE: Pull brushes straight out of holders, being
careful not to stretch springs. If reusing same brushes,
mark brush and brush cap for replacement to original
position.
3. Install new brushes and brush caps.
NOTICE: When reinstalling same brushes that were
removed, replace on same side of motor they were
on originally. Match curve on ends of brushes to
curve on commutator.
