Priming the pump for the first time or after service
(Continued)
Priming the Pump
• Release all pressure from filter, pump, and piping system; see the filter owner’s manual.
• In a flooded suction system (water source higher than pump), the IntelliFlo
® VS pump will
prime itself when suction and discharge valves are opened.
• If the IntelliFlo ® VS pump is not in a flooded suction system, remove clamp and lid ; fill the
pump with water.
• Do not lubricate the lid o-ring. The original equipment o-ring contains a permanent internal
lubricant.
NOTICE: If you replace the o-ring with a non-internally lubricated o-ring, you may need to apply a
silicone based lubricant.
• Clean and inspect o-ring; reinstall on lid.
• Replace clamp on strainer pot; turn clockwise to tighten clamp.
NOTICE: Tighten the pump clamp by hand only (no wrenches)!
Pump should prime now. Priming time will depend on vertical length of suction lift and horizontal
length of suction piping. If pump does not prime, make sure that all valves are open, suction pipe end
is under water, pump suction is below water level, and that there are no leaks in suction pipe.
To prime the IntelliFlo
® VS pump:
1. Turn the pump clamp and lid in a counterclockwise direction until it
stops and remove them.
2. Fill the pump strainer pot with water.
3. Reinstall the pump clamp and lid onto the strainer pot. The pump is
now ready to prime.
4. Make sure all electrical connections are clean and tight.
5. Open the air release valve on the filter, and stand clear of the filter.
6. Switch the IntelliFlo
® pump on at the circuit breaker. Ensure that
the green power light is on.
7. Press the Speed 1 button to select the pump speed of 750 RPM.
8. Press the Start button to start the pump. Use the Up/Down button to increase the speed as
necessary to prime the pump.
9. When water comes out of the air release valve, close the valve. The system should now be
circulating water back to the pool without air bubbles showing in either the hair and lint pot or at the
pool return fittings.
10. Use the Up/Down button to adjust the operating speed as desired.
