ELECTRICAL WIRING INSTRUCTIONS
1-PHASE OR 3-PHASE PUMPS
ALL WORK MUST BE DONE BY A REGISTERED ELECTRICIAN AND MUST COMPLY WITH THE
ELECTRICITY REGULATIONS AND CODES OF PRACTICE.
1. The pump station requires a dedicated 20 amp power supply from the nearest switchboard.
2. Supply and install the following rigid conduits between the control panel (or cubicle) and the pump
chamber:-
1 x 32mm for single pump
2 x 32mm for dual pumps
Plus 1 x 32mm for float/sensor cables
• Conduits are to be lock nutted into chamber wall and into the control panel.
• Large radius or swept bends only to be used.
• Ends of conduit to be sealed to prevent the transfer of sewer gas which is extremely corrosive to
electrical components.
3. Run pump and float flexible cables directly into the control panel, via the conduits detailed above.
If the control panel distance exceeds the available cable length, an approved accessible joint must be made
to extend the cables.
4. Some floats have 3 conductors for change-over switching, it is important to seal off the spare core, as
under certain circumstances it could be alive.
5. Before lowering the pumps into the tank, check that the pump is operating. For 3-phase pumps, check
directions of rotation, by observing the direction of the starting kick when power is momentarily appliedl.
The starting kick should be anti-clockwise when looking down the pumps.
Check correct setting of overload to match the pump running current.
6. Check starting and stopping of each pump, and the auto-alternating feature of the dual pumps.
7. Check operation of the alarm by lifting up the alarm float.
8. Float operating levels may be adjusted by changing the length of the cable drop.
