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. Screw impeller onto the motor shaft (clockwise to
tighten).
5. Screw in the impeller lock screw (counter-clockwise to
tighten).
Note: Insert a 1/4" hex Allen wrench into the motor
shaft through the hole in the rear motor fan cover.
This will prevent the motor shaft from rotating and
you screw in the impeller lock screw.
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. Assemble the motor sub-assembly to the strainer pot-
pump body. Tighten the 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.
Restart Instructions
If VS2 Variable Speed Pump is installed below 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 power to the pump.
6. Press the Start/Stop button on the drive keypad. If
the pump is currently scheduled to run it will start.
Note: If the pump is not schedule to start, press a
Speed button to begin a manual override that will
start the pump.
7. 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.
