1.1
Safety
All work should be undertaken in compliance
with the relevant accident prevention regula-
tions according to BGV C22. A second per-
son is required for safety reasons, particularly
when inspecting tanks.
In addition, the applicable regulations and
standards must be respected during installa-
tion, assembly, maintenance, repairs etc.
Relevant information can be found in the cor-
responding sections of these instructions.
The entire system must always be switched
off and secured against unauthorised reset-
ting during any work on the system or system
components.
The tank cover must always be kept closed,
except during work inside the tank, otherwise
the risk of accidents is high. The rain guard
cover fitted upon delivery is only transport
packaging, it is not suitable for pedestrian
loading and is not childproof. After delivery, it
must be immediately replaced with a suitable
cover provided by the customer.
GRAF provides an extensive range of acces-
sories, which are all coordinated and can be combined 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
Labelling requirement
The post with holder for sign "Extinguishing Water Extraction Point", for securing directly to the intake
pipe, is included in the scope of delivery. The corresponding sign in accordance with DIN 4066-B2 with
the relevant extinguishing water volume details is supplied unlabeled for individual printing by the cus-
tomer. The sign must be attached to the holder permanently in a highly visible place.
1.3
Acceptance
Every new extinguishing water tank should be accepted by an officer from the relevant authority and is to
be checked for its function. The fire protection specialist responsible verifies and calculates the amount of
extinguishing water needed. Please note that the actual useful volume of extinguishing water may be up
to 10 % below the stated total tank volume.
