WARNING:
DO NOT RUN THE PUMP BEFORE PRIMING IT, SINCE THE SEAL AND IMPELLER COULD BE PERMANENTLY DAMAGED.
a) PRIMING: These pumps are not self-priming. For best
priming, fill the pump casing and the suction line full
with water.
To prime the casing – Remove the priming plug and the drain
plug (See Fig. 2). Pour clean water into the priming hole.
Replace the drain plug. Fill the pump casing full. Rotate the
motor shaft manually from the back of the motor to release
internal air pockets inside the casing. Refill, if necessary, at
the priming hole. Replace the priming plug.
b) STARTUP: Dry operation may damage the water-lubricated
seal inside the pump. If the pump does not deliver water
within seconds after startup, stop the motor and repeat
the priming operation. Several starting attempts may be
necessary to expel all of the air from the pump and
suction lines.
c) CONTINUOUS OPERATION: Check the pump periodically
for loose or rubbing parts. Service the pump immediately if
any unusual noise, leaks or vibrations develop.
WARNING - ELECTRICAL PRECAUTIONS
All wiring, electrical connections, and system grounding
must comply with the National Electrical Code (NEC)
and with any local codes and ordinances. Employ a
licensed electrician.
WARNING - RISK OF ELECTRICAL SHOCK
Before servicing motor-operated equipment, shut off the power at
the main electrical panel and disconnect the power supply from
the motor and the accessories. Use safe working practices during
servicing of equipment.
a) LUBRICATION: The pump itself does not need lubrication.
Refer to instructions provided with the motor for motor
lubrication and maintenance.
b) REPLACEMENT OF SEAL: If available, refer to the repair
parts list illustration showing the relative location and
names of all components to assist you while following these
instructions.
Disassembly:
1) Disconnect piping and wiring.
2) Remove the four nuts to dismount the pump casing from
the motor housing.
3) Remove motor's end cover (if required).
4) Secure motor's shaft end with screwdriver and remove
impeller by turning it counter clockwise.
5) Remove the spring seal from the shaft and slide the seal
plate off.
6) Remove the ceramic seat and its rubber housing from
the seal plate.

MAINTENANCE

DRAINING: Should the pump be subject to freezing
temperatures, it will be necessary to completely drain the
fluid from the pump and lines. To drain the pump casing,
remove the drain plug and the priming plug. Disconnect the
suction line at a connection close to the pump casing and
allow the water to drain from the suction line. Operate the
pump for a few seconds only to clear water from the impeller.
Replace the suction line, carefully cleaning the threads and
applying fresh thread compound.
ROTATION: The arrow on the front of the pump casing
indicates the correct rotation of the impeller during operation.
Wire the motor as described above. If it is not turning in the
proper direction, refer to the motor wiring instructions.
Reassembly:
1) Clean all parts thoroughly. Inspect for damage or wear.
2)
Liquid soap the rubber only of the stationary seal seat.
Use clean thumbs only to press seat into seal plate.
Make sure that seat is fully seated and wipe clean.
3) Slide the seal plate onto the shaft, being careful not to
damage the ceramic seat.
4) Lightly soap the internal rubber ring of the rotary spring
seal assembly and slip it onto the motor shaft with the
shiny side of the ring towards the ceramic seat.
5) Reassemble the impeller onto the shaft. Tighten "hand
tight" only.
6) Place a new gasket onto the seal plate.
7) Place the casing into position and attach the motor
using new spring washers and existing bolts. Use thread
locking/sealing compound on casing to prevent leaks.
Do not over-tighten the bolts.
8) Check that the impeller is not rubbing with the pump
casing by rotating the motor shaft by hand.
9) Replace motor's end cover (if required).
10) Reconnect piping and wiring.
11) Reprime pump system.
PRECAUTIONS
a) Whenever reassembly of pump is involved, check to see
that the impeller rotates freely within the casing.
b) Never remove the water flinger from the motor shaft
unless replacing a damaged flinger. Be sure the motor
has a flinger installed at all times.
