VI. Electrical connection
This mark located outside the connection box is a warning for an electrical
hazard.
1. Ensure the mains voltage is the same as the value shown on the motor plate and that
the pump is safely connected to ground/earth.
2. The single phase models are supplied with plug and lead and can be connected directly
to the mains supply. The 3 phase models should hook up with a circuit breaker.
VII. Wiring diagram
WARNING:
Risk of electric shock - This pump has not been investigated for use in swimming pool or marine areas.
To reduce the risk of electric shock, connect only to a properly grounded, grounding-type receptacle.
Before operation, please ensure the voltage is correct and the circuit breaker and ground-
ing connectors are all connected in accordance with local regulations.
2. For installation with inlet pressure, remove the priming plug and allow the water to flow
into the priming chamber until all air is expelled.
3. The priming procedure should be repeated until all air is expelled and the pump delivers
a full stream of water without air bubbles.
4. The pump must always be checked for prime if not used for a prolonged period. It is
imperative to fill the pump with liquid before operation as dry running causes
irreparable damage to the mechanical seal.
5. When 3-phase motor is supplied, please ensure if the rotation is correct. You can switch
any of the 2 wires to change the rotation.
