DO NOT run the pump dry. If the pump is run dry, the mechanical seal will be damaged and the pump will start leaking. If this
occurs, the damaged seal must be replaced. ALWAYS maintain proper water level. If the water level falls below the suction port,
the pump will draw air through the suction port, losing the prime and causing the pump to run dry, resulting in a damaged
seal. Continued operation in this manner could cause a loss of pressure, resulting in damage to the pump case, impeller and
Pump Reassembly
1.
When installing the replacement seal into the seal
plate, use soapy water to wet the rubber boot
before pressing it into the seal plate.
2.
Remount the seal plate to the motor.
3.
Before installing the rotating portion of the seal on
the motor shaft, wet the motor shaft with soapy
water and slide the seal onto the motor shaft.
Ensure that the carbon face contacts the ceramic
face of the stationary seat. Press the seal into
the seal plate with your thumbs and wipe off the
ceramic with a clean cloth.
4.
Grease the motor shaft thread and screw impeller
onto the motor shaft.
5.
Screw in the impeller lock screw (counter-clockwise
to tighten).
6.
Remount the diffuser onto the seal plate. Make
sure the plastic pins and holding screw inserts are
aligned.
7.
Grease the diffuser quad ring and seal plate O-ring
prior to reassembly.
8.
Grease the bolt threads, assemble the motor sub-
assembly to the strainer pot-pump body by using
the two through bolts for proper alignment. Do not
tighten the through bolts until all 4 bolts are in place
and finger tightened.
9.
Fill the pump with water.
10. Reinstall the pump lid and plastic clamp; see the
next section, 'Restart Instructions' .
11. Re-prime the system.

the water level of the pool, close return and suction lines
prior to opening hair and lint pot on pump. Make sure to
re-open valves prior to operating.
Priming the Pump
The pump strainer pot must be filled with water before
the pump is initially started.
Follow these steps to prime the pump:
1.
Remove the pump lid plastic clamp. Remove the
pump lid.
2.
Fill the pump strainer pot with water.
3.
Reassemble the pump cover and plastic clamp onto
the strainer pot. The pump is now ready to prime.
4.
Open the air release valve on the filter, and stand
clear of the filter.
5.
Turn on the switch or time clock.
6.
When water comes out of the air release valve,
close the valve. The system should now be free of
air and recirculating water to and from the pool.
