1. 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.

When entering the tank it is indispensable to empty all chambers. Under no
circumstances one must not enter the container if there is still an unemptied
chamber.

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.
