CLEANING/REPLACING IMPELLER
NOTE:
First, follow instructions under
“Pump Disassembly”.
1. Remove two screws fastening dif-
fuser to seal plate; remove diffuser
(See Key Nos. 9 and 10, Figure 15).
Exposed impeller can now be
cleaned.
2. If impeller must be replaced, loosen
two machine screws and remove
motor canopy (See Figure 3). If
motor has a capacitor, go to step 3.
If motor does not have a capacitor,
go to step 6.
Capacitor voltage may
be hazardous.
To discharge capacitor,
hold insulated-handle screwdriver by the
handle and short capacitor terminals
together. Do not touch metal screw-
driver blade or capacitor terminals. If in
doubt, consult a qualified electrician.
3. Unscrew capacitor clamp and
remove capacitor. Do not dis-
connect capacitor wires to motor.
4. Slide 7/16" open end wrench in
behind spring loaded switch on
motor end of shaft; hold motor shaft
with wrench on shaft flats and
unscrew impeller by turning counter-
clockwise when looking into eye of
impeller.
5. To reinstall, reverse steps 1 through
4. Mount diffuser as shown in
Figure 11.
6. See directions under “Pump
Reassembly”.
CLEANING/REPLACING THE
SHALLOW WELL EJECTOR
NOTE:
First, follow instructions under
“Pump Disassembly”.
1. Unscrew venturi and remove it (See
Figure 4).
2. If necessary, unscrew and remove
nozzle with a 5/8" deepwell socket
wrench (See Figure 5).
3. Clean venturi and nozzle by care-
fully inserting an ice pick or other
small diameter pointed tool, dis-
lodging foreign material.
IMPORTANT:
Be careful not to enlarge
hole in nozzle or venturi. If venturi and
nozzle cannot be cleaned or are dam-
aged while cleaning, replace.
4. Reinstall venturi and nozzle by
threading clock-wise into pump
ejector body insert until snug. Do
not overtighten.
5. See directions under “Pump
Reassembly”.
