Nautilus Filter Diverters

Installation

An overflow indicator ('V' shaped nick) on the Nautilus covers indicates the top of the Nautilus's overflow outlet, this will help position the Nautilus at the correct level on the downpipe:

The overflow indicator should be at a level equal to the height of the centre of the rain tank's overflow outlet.

As above, or if more hydraulic head pressure is required: Position the lowest point of the overflow outlet's invert at least 300mm below the rain tank's capacity level. This procedure will minimise backflow in the event of heavy rainfall.

Multiple Downpipes to Rain Tank

Connecting more downpipes to the rain tank can be achieved by positioning each Nautilus at an equal height to the rain tank's capacity, and fitting an equal amount of overflow outlets to the rain tank, or fitting an appropriate sized overflow outlet to the tank and utilizing a junction to connect pipework.

Rain Tank Preparation

Replacing the rain tank's leaf strainer function allows a secure access cover over its opening, which will prevent accidental entry and sunlight entering to inhibit algae growth. The overflow outlet's mosquito-proof screen is not required.
