General notes
1.1
Safety
The relevant accident prevention regulations according to BGV C22 have to be observed when
conducting any works. Especially when inspecting tanks a second person is required for safety reasons.
Furthermore, the relevant regulations and standards have to be observed during installation, assembly,
maintenance, repair, etc. You will find information about this in the related sections of these instructions.
During all works on the system respectively on system components the overall system has to be
decommissioned and secured against unintentional restart at all times.
The tank cover has to be closed at all times, except when conducting works on the tank, otherwise there
is a very high risk of accident. Only original GRAF covers or covers approved by the company GRAF in
writing are to be used.
The company GRAF offers a comprehensive portfolio of accessories that are aligned with each other and
can be developed into complete systems. Using deviating accessories can lead to impairments of the
functionality of the system and thus to the liability for damages resulting thereof expiring.
1.2
Identification obligation
All lines and tapping points of process water have to be labelled with the words “
No drinking water
” in
writing or visually (DIN 1988 part 2, section 3.3.2.) in order to avoid an accidental connection to the
drinking water network even after years. Even when there are correct labels, irritations are possible, e.g.
through children. That is why all tapping points of process water have to be installed with
child-proof
valves.

Transport
The transport of the tanks may only be undertaken with the appropriate transport machinery. During the
transport the tanks are to be secured against slipping or falling. If the tanks are secured for transportation
with webbing straps, it is to be ensured that the tanks remain undamaged. Dragging or lifting the tanks
with steel cables or chains is not permitted.
Stress and excess loading caused by impact are to be avoided. Under no circumstances are the tanks to
be rolled or slid over the ground surface.
