Priming the Pump
1. The pump strainer pot must be filled with water before the pump is initially started. Follow these steps to prime the pump.
a. Remove the pump lid and locking ring.
b. Fill the pump strainer pot with water.
c. Reassemble the pump lid and locking ring onto the strainer pot. The pump is now ready to prime.
d. Open the air release valve on the filter, and stand clear of the filter.
e. Turn on the switch or time clock.
f. 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.

developing full flow. If the pump does not prime, see the "Troubleshooting" section below.
