1.1
Safety
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. Rel-
evant notes can be found in the corresponding
sections of these instructions.
During all work on the system or parts of the
system, the entire system must always be ren-
dered inoperable and secured to prevent unau-
thorised reactivation.
Except in the event of work carried out in the
tank, the cover of the tank must always 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 immedi-
ately following delivery (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 other accessories may lead to impediments to the
system's functional capability, therefore invalidating liability for resulting damage.
1.2
Identification obligation
All service water pipes and outlets must be identified in writing with the words "Not drinking water" or in
the form of images (DIN 1988 Part 2, Para. 3.3.2.) in order to avoid inadvertent connection with the drink-
ing water mains even after a number of years. Mix-ups, e.g. by children, may still occur even in the case
of correct identification. All service water extraction points must therefore be installed with valves with
child-proof locks.
