up feed pipework to the underground tank gets blocked, as it will then likely prevent flooding of the
room where the Controller is located. The overflow can be connected with a Universal Waste Adapter.

The Level Probe, a Conductivity Probe
The supplied conductivity Level Probe is used as a minimum water level detector in
the rainwater tank. The standard length of cable supplied is 15m. This can be
extended to order, up to 100m. It carries a very low voltage/current.
Fix the Level Probe in the tank so that it is suspended approximately 0.3 to 0.4 metres above the
bottom, depending on the shape of the tank and position of pump inlet. It should be positioned to
ensure there is no risk of cavitation or air entrainment to the pump inlet. If in doubt you MUST consult
an approved and qualified plumber. The height of the Level Probe determines the minimum water
level of the tank at which the pump will run.
The Level Probe works by conductivity. When the Level Probe's contacts are immersed in water a
circuit is completed and the control unit detects this. When the prongs of the probe come out of the
water, topping up is activated.
Note: The Level Probe's length of cable can be extended to a maximum of 100m.
OPERATIONAL ADVICE NOTES – Ensure that the tank is entirely free of debris before installing a
pump and this controller. Sand, grit, cement and even plastic swarf from manufacturing and other
