Mark wires for correct reassembly.
4. Remove pressure switch tube from
barbed fitting on pump body.
Remove pressure gauge and drain
plug and allow pump to drain.

CLEANING/REPLACING IMPELLER
NOTE:
First, follow instructions under
“Pump Disassembly”.

fuser to seal plate; remove diffuser
(See Figure 3). Exposed impeller
can now be cleaned.
2. If impeller must be replaced, loosen
two machine screws and remove
motor canopy (See Figure 4).
Capacitor voltage may
be hazardous.
To discharge capacitor,
hold insulated-handle screwdriver BY
THE HANDLE and short capacitor
terminals together. Do not touch metal
screwdriver blade or capacitor termi-
nals. If in doubt, consult a qualified
electrician.
3. Unscrew capacitor clamp and
remove capacitor. Do not discon-
nect capacitor wires to motor.
4. Slide 7/16" open end wrench in
behind spring loaded switch on
motor end of shaft; hold motor shaft

REMOVING OLD SEAL
1. Follow instructions under “Pump
Disassembly.”
2. Follow steps 1 through 5 under
“Cleaning/ Replacing Impeller.”
3. Unscrew four nuts holding pump
back half to motor. Remove rotating
half of seal by placing two screw-
drivers under back half of pump
body and carefully prying up (See
Figure 5). Back half of pump body
will slide off shaft, bringing seal

IMPORTANT:
Be sure you do not
scratch or mar shaft; if shaft is marred, it
must be dressed smooth with fine emery
or crocus cloth before installing new
seal.
Do not
reduce shaft diameter!
4. Place pump body half face down on
flat surface and tap out stationary
half of seal (See Figure 6).

seat is up. If seal will not seat cor-
rectly, remove, placing seal
