Impeller Replacement

Risk of electric shock. Can shock, burn or kill. To reduce the risk of hazardous or fatal
electrical shock, follow instructions A through B, below:
A. This pump has an approved 3-conductor
power cord with 3-prong, grounding-type
plug. Connect the pump only to a properly
grounded, 3-prong outlet. If the sump pump
circuit has a 2-prong outlet, replace it with a
grounded 3-prong outlet installed according
to code.
First: Turn off power to the pump, disconnect
the discharge piping, and lift the pump out of the
sump BY THE HANDLE ON TOP OF THE MOTOR
(not by the cord).
Step 1:
A. Invert the pump and secure it from tipping.
B. Remove the three screws holding the motor to
the base and lift the base off the motor.

Do not remove the seal plate, as
the motor is full of oil and will spill.
Step 2: Hold the motor shaft with a screwdriver
and unscrew the impeller as shown.
NOTICE: The impeller has a left-hand thread, so
it loosens to the right (

).
B. Unplug the pump before handling or servicing
it. If your basement floor is wet, turn off all
power before walking on it. If the shut-off box
is in the basement, call your electric company
or hydro authority to shut off the service to
the house, or call your local fire department
for instructions. After turning off the power,
remove the pump for service.
Step 3: Thread the new impeller onto the motor
shaft as shown (left-hand thread – tightens to
the left ).
Step 4: Re-mount the base on the motor. Be
sure to mount it so that the switch is clear of the
discharge and all other obstructions in the sump.

Last: Run the pump through one complete cycle
after it is assembled and reinstalled. It should
operate correctly and you should not hear any
sounds of scraping or dragging from the pump.
