General notes
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. 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 accessories that have not been approved by GRAF results in the
exclusion of the warranty/guarantee.
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
.
