IMPORTANT!
Place the pump as close to the water
source as possible. Increases in suction
lift will lower pump performance. Do not
exceed maximum suction head of 26 feet.
Priming
Before the pump can develop suction
or “lift” at the water source, the pump
impeller must first be primed by filling
the pump housing with water. Once the
GP3410 has been primed, additional prim
ing should be required only if the pump
has been drained or otherwise emptied.
Remove the filler plug at the top of the
1.
pump housing. Use care not to lose the
sealing ring beneath the filler plug.
IMPORTANT!
A damaged or missing filler plug seal may
allow air to leak into the pump housing.
