cAUTION: All pumps must be primed by
filling the pump cavity with water before they
are first operated. This may take several gallons
of water, as the entire inlet line will be filled in
addition to the pump cavity. The longer the inlet
line, the more water is required for priming.
1. Disconnect the 1-1/2 in. outlet union and
separate the pipe.
2. Remove the air relief plug on top of pump
and the 1-1/4 in. priming plug with pressure
gauge or plug. Refer to Pump Preparation
Step 5.
3. Slowly fill pump cavity until water comes out
of air relief hole on top of the pump.
