If the Challenger
®
Centrifugal 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 reopen valves prior to operating.
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 in
your pool (half way up skimmer opening). If the water level falls below the skimmer opening, the pump will draw air through
the skimmer, losing the prime and causing the pump to run dry, resulting in a damaged seal. Continued operation in this
matter could cause a loss of pressure, resulting in damage to the pump case, impeller, and seal and may cause property
damage and personal injury.
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.
2. Fill the pump strainer pot with water.
3. Reassemble the pump lid 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.
7. This pump will prime within thirty (30) minutes. Do not allow your pump to run longer than this time
without developing full flow. If the pump does not prime, see “Troubleshooting” on page 11.
8. Two speed pumps should run on high speed for priming.
