Safety

All work should be undertaken in compliance with the relevant accident prevention regulations according
to BGV C22. A second person is required for safety reasons, particularly when inspecting tanks.
In addition, the applicable regulations and standards must be respected during installation, assembly,
maintenance, repairs etc. Relevant information can be found in the corresponding sections of these
instructions.
The entire system must always be switched off and secured against unauthorised restarting during any
work on the system or system components.
The cover must always be kept closed, except during necessary work on the filter, otherwise the risk of
accidents is high. The fit of the cover should be regularly checked. It is also prohibited to stand on the
substrate filter cover.
GRAF provides an extensive range of accessories, which are all coordinated and can be combined to
form complete systems. The use of other accessories may result in restrictions of the system's
functionality and to liability being revoked for damage incurred.
These instructions only apply to the installation of the substrate filter in a Carat tank. For more information
about the Carat tank, please refer to the relevant installation manual
