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, servicing, repair, etc. Relevant notes can be found in the corresponding sections of these in-
structions.
During all work on the system or parts of
the system, the entire system must al-
ways be rendered inoperable and se-
cured to prevent unauthorised reactiva-
tion.
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 al-
ways be kept sealed, as this otherwise
constitutes 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.
