PUMP PRIMING & STARTUP
PRIMING
CAUTION: All pumps must be primed
(filling the cavity with water) before they are
first operated. This may take several gallons
of water, as the suction line will be filled in
addition to the pump cavity.
1. Remove the priming plug with pressure
gauge and air relief plug.
