Impeller Replacement

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: Turn pump upside down, holding motor
to base and lift motor off base. Remove six
bottom screws; take off lower volute.
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 (

).
For parts or assistance, call Simer Customer Service at 800-468-7867
Step 3: Thread the new impeller onto the motor
shaft as shown (left-hand thread – tightens to the
left ).
Step 4: With the pump upside down, reinstall
lower volute, ensuring arrows and rib indicators
are aligned. Re-mount the motor on the base.
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.
