INSTALLATION MANUAL
PART 4B: PRIMING A PUMP MOUNTED ABOVE A TANK
1. Ensure a foot valve or non-return valve is fitted to the end of the suction line.
2. Remove the priming port plug on the top
of the pump casing.
3. Slowly fill the pump casing and suction
line with water through the priming port
(best done with a funnel) allowing air
to vent as the water fills the suction line
and pump casing. If there are any leaks,
repair these immediately. If no leaks are
present, proceed.
