2 Please note:
2.1 Safety
All work should be undertaken in compliance with national accident prevention regulations. A second per-
son is required for safety reasons, particularly when inspecting tanks.
In addition, the applicable national regulations and standards must be respected during installation, assem-
bly, maintenance, repairs etc.
During all work on the system or system components, the entire system must always be switched off and
secured against unauthorised reactivation.
The tank cover must always be kept closed, except during work inside the tank, otherwise the risk of acci-
dents is high. Only original GRAF covers, or covers approved by GRAF in writing, are to be used.
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 the functionality of the system being impaired
and in liability being revoked for any damage incurred.
2.2 Assembly tool
The tools used to assemble the stainless steel hose clips must themselves be of stainless steel. Otherwise,
the stainless steel parts may corrode following contact with the non stainless steel tools.
2.3 Aeration and ventilation
All tanks must be ventilated. Additional ventilation ducts or openings should be arranged if required. If this
occurs, the ventilation ducts should be arranged so that natural ventilation is possible (chimney effect).
2.4 Installing the tank
2.5 Tank labelling
The tanks are numbered when plants are fitted with more than one. These numbers can also be consulted
on the technical drawings.
2 Please note:
Refer to the installation instructions provided with the Carat XXL tanks
when installing them. Please note in particular the installation conditions
applying to the tanks.
