Priming Pump
Release all air from filter, pump and piping system: refer filter owner’s manual.
In a flooded suction system (water source higher than pump), pump will prime
itself when suction and discharge valves are opened.
If pump is not in a flooded suction system, disconnect power supply to pump
and remove trap cover handle ring and trap cover; fill trap and pump with
water.
Do not lubricate the trap cover O’ring. The original equipment O’ring contains
a permanent internal lubricant.
NOTICE: If you replace the O’ring with a non-internally lubricated O’ring, you
may need to apply a silicone based lubricant.
Clean and inspect O’ring; reinstall on trap.
Replace trap cover and handle ring on trap; turn handle ring clockwise to
tighten cover.
NOTICE: Tighten trap cover handle ring by hand only (no wrenches!)
Pump should prime now. Priming time will depend on vertical height of suction
lift and horizontal length of suction piping. The self-priming time range is 1 to 5
minutes for a height difference of 2 to 3 metres, under normal installation
conditions. Normal conditions are understood to be: with suction having an
internal diameter of DN 50mm, water temperature at 20
o
C, and 50Hz mains
power supply.
Should the pump not prime, ensure that all valves are open, lint trap is clear of
debris and suction pipe end is submersed in water, and that there are no leaks
in suction pipe.
