It is essential to connect the pump to a suitable ground.
The following diagram should be used when making the electrical connections to the pump terminals.
Use is only permitted if the electric installation has safety protection systems in accordance with personal safety
regulations in force in the country where the product is to be installed.
9 CHECKS PRIOR TO PUTTING INTO SERVICE
THE PUMP SHOULD NEVER BE ALLOWED TO OPERATE OFF LOAD
Check that the voltage and frequency of the incoming mains electricity supply correspond to those on the pump’s
specification plate.
Unscrew the transparent pre-filter cover and fill the pre-filter with water until
the water level reaches the suction hole. Replace the pre-filter cover and
hand-tighten only, ensuring that it is fully tightened.
Check the pump shaft can freely rotate.
Check the that the direction of motor rotation corresponds with that indicated on the
specification plate (the fan should rotate in a CLOCKWISE DIRECTION, when viewed from
the rear of the motor. If the motor is three-phase and it is observed that it is rotating in the
opposite direction, then two of the supply phases should be inverted at the protection panel.
10 PUTTING INTO SERVICE
Open all valves, both suction and impulsion, and switch on the pump.
Wait a reasonable time for the pump and suction piping to self-prime. If this takes too long, then the priming
process should be repeated.
Once the pump has correctly self-primed and the pre-filter body is seen to be full of water, the motor current should
be checked, and the thermal relay adjusted appropriately.
