PRIMING THE PUMP
Before using the pump for the first
time the inlet (suction) side must be
filled with water to prime the pump as
follows:-
1. With all inlet pipes/hoses, but no
outlet hose connected, pour
water into the outlet port until all
the air is expelled.
2. Connect the outlet hose to the
outlet port.
If the outlet hose is already connected, a priming port and threaded plug are
provided, adjacent to the outlet as shown.
NOTE: As the priming hole is quite small, it is recommended to fill the inlet
(suction) pipe with water before connecting to the pump, and
top up through the priming port once the pipe is connected. A
non-return valve will need to be fitted to the inlet pipe for this
purpose.
3. Switch on the pump.
• Water should start to flow through the system.
4. Check for leaks and make good if necessary.
5. Adjust any device such as a non-return valve, which may be fitted to the
outlet side of the pump, to maximise efficiency.
• Do not place any restriction on the inlet or discharge hoses.
• Remember - this pump is designed for pumping CLEAN WATER ONLY.
DO NOT USE for pumping chemicals or other flammable or corrosive
liquids.
