Start-up and Adjustment

• The pump is normally self-priming if suction lift is 5 ft (1.5m) or less and the steps below
• Pumps are shipped from the factory with water in the pump head to aid in priming.
4.2.1 Start-Up/Priming for FastPrime™ Heads
Read this entire section completely before proceeding.
When all precautionary steps have been taken, the pump is mounted, and the tubing is
securely attached, you may now start priming the pump.
