At initial start-up, pump must be primed by filling hair and lint trap
with water. To prime pump, remove cover from hair and lint trap:
fill pump and suction trap with water. Replace cover (make sure
the O-ring is in place) and tighten lock ring. Pump will now prime,
with priming time depending upon lift and horizontal distance of
suction piping.
Drain liquid from pump through plug at bottom front section of volute.
It is recommended to apply a good rust inhibitor into liquid
end to prevent corrosion. Be sure motor is kept dry and covered.
In mild climate area, when freezing may occur, run pump and filter
equipment continuously to prevent freezing.
