WIRING DIAGRAM
• SINGLE PHASE
Note: Electrical wiring configuration may vary in different countries and installers should
ensure compliance to these regulations and standards.
STARTING & PRIMING THE PUMP
The pump is not self-priming. Therefore, if the water level is below the pump a non-return
valve must be installed below water level. The pump and inlet line must be primed prior
to start up.
For non-flooded installations a strainer and check valve (non-return valve) is recommended.
High suction lift or long suction lines will require additional time to prime and can
severely affect the performance of the pump.
WARNING
!
Mechanical seals if allowed to run dry can be damaged rapidly and may need to be replaced.
WARNING
!
If you are unable to prime the pump please see the trouble-shooting guide.
Ensure all suction and discharge valves are open before you start the pump, operating the
pump with these valves shut can damage the pump.
MAINTENANCE
In Climates where the pump may be exposed to frost or freezing, care must be taken to
ensure the pump is protected from damage.
It is recommended that if the pump is not used during this winter period it should be
drained completely. Never run the pump dry.
If at all possible remove the pump away and store it in a dry location during this period.
When you re activate the pump ensure all seals and o-rings are in operational condition,
re-grease if necessary (replace) if unsure of condition.
• Check that the motor shaft moves freely before re-activation.
