INSTALLATION MANUAL

b.  Inserting the plug into the  

suitable socket outlet:

It is recommended to connect the 
switching unit to a socket outlet 
protected by a residual current device 
– RCD (also known as an earth leakage 
circuit breaker – ELCB) with a rated 
tripping current not exceeding 30mA.

 Note: 

Contact a qualified electrician if you 

cannot verify that the socket outlet is protected 
by RCD. RCD tripping indicates an electrical 
problem. If the RCD trips and will not reset, 
have a qualified electrician inspect and repair 
the electrical system.

4.  Protect your pump solution from wind, rain 

and sun with a suitable pump cover.

Congratulations, the  
installation is complete!

INSTALLATION

ELECTRICAL CONNECTION

1.  Before connecting the unit to an electrical 

power supply, connect the pump and 
switching unit using the provided IEC 
appliance connectors on the end of the 
interconnection cords. Ensure there are no 
water traces on the connectors. Push them 
firmly into each other to ensure intended 
splash (water) proof protection.

2.  Check that the tank level sensor is securely 

connected to the base of the unit using the 
bayonet fitting, and the lead is cable tied 
to the connecting pipework to stop it from 
being pulled free. 

3.  Connect the switching unit to the power 

supply by either: 

a.   Hard  wiring:   

Local authorities may require the pump 
to be hard wired.

Important: 

If this applies to you, the electrical 

connection must be done by a qualified 
electrician with pump knowledge according  
to the National wiring rule (AS/NZS 3000) and/
or any local council requirements. 

WARNING: Hazardous  
voltage can cause shock,  
burn, or cause death.

The supply voltage for the  
Digital Water Switch must be 
within 230–240V.

If the power supply cord or  
pump interconnection cord is 
damaged, it MUST be replaced 
by an authorised service agent  
to avoid hazard.

To avoid dangerous or fatal 
electrical shock, turn off power 
to the digital water switch 
before working on any electrical 
connections.

3.  Insert the float into the tank:  

Surface tank installations: 

Drape the level sensor up against the 
side of the tank, lifting the cable until the 
float is 70mm above the suction. Mark the 
positions of the cable that is level with the 
roof of the tank using marking tape (not 
supplied).

In-ground installations: 

Lower the float into the tank. Position the 
float 70mm above the suction fittings or 
pump inlet. Use marking tape on the cable 
to indicate top of tank position. 

4.  Once in position, route the cable to the 

switching unit and plug the connector to 
the matching receptor on the underside 
of the VFB-DSU. Using cable ties, fix the 
cable to the pipework near the switching 
unit to avoid the cable being pulled free.
