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 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.
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 immediately 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
drinking 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
.
