It is important that the outlet pipework is protected from sunlight and
frost damage by ensuring that around the Tricel Puraflo modules is
backfilled with suitable material.

Secondary treatment Tricel Puraflo systems require an effluent filter be installed at the
outlet of the septic tank.

On sites in which complete secondary treatment systems i.e. septic tank AND Tricel
Puraflo modules, are being installed, the effluent filter must be installed in the
septic tank on site by the installer unless the septic tank has been supplied with the
effluent filter pre-installed, see section 5.3.2.1.

On sites in which a Tricel Puraflo system will be installed with a pre-existing septic
tank, an effluent filter must be installed at the outlet of the septic tank, if not
already present.
