General notes
1.1
Security
The relevant accident prevention regulations according to BGV C22 must be observed during all work.
Particularly when walking on the tanks, a 2nd person is required to secure the tank.
The relevant regulations and standards must additionally be
taken into consideration during installation, assembly, servic-
ing, repair, etc. Relevant notes can be found in the corre-
sponding sections of these instructions.
During all work on the system or parts of the system, the entire
system must always be rendered inoperable and secured to
prevent unauthorised reactivation.
The tank must be thoroughly cleaned prior to commissioning,
because transport and storage may result in dirt or rainwater
entering the container.
Except in the event of work carried out in the tank, the cover of
the tank must always be kept sealed, as this otherwise consti-
tutes a maximum risk of accident. The rain protection installed
on delivery is merely transportation packaging. It cannot be
walked on and is not child-proof; it must be replaced with a
suitable cover immediately following delivery (drinking water
telescopic dome shaft with corresponding cover)!
Only original GRAF covers or covers approved in writing by GRAF must be used.
GRAF offers an extensive range of accessories, all of which are designed to match each other and which
can be extended to form complete systems. The use of accessories that have not been approved by
GRAF results in the exclusion of the warranty/guarantee.
