2 Safety
2.1 Intended use
The check valve is intended to be installed in the pipework system and its purpose is to prevent the return
flow of media into the pipework system. The permissible operating conditions are specified in these
operating instructions.
The check valve is suitable for the media listed in these operating instructions; see section 4.5 "Media".
Operating conditions and applications deviating from these require the approval of the manufacturer.
Only media may be employed to which the materials used for the valve body and seals are resistant.
Contaminated media or usage outside of the pressure and temperature specifications can lead to damage
to the valve body and seals.
Avoidance of foreseeable incorrect use
Never exceed the permissible usage limits specified in the data sheet or in the documentation
with regard to pressure, temperature, etc.
Follow all safety instructions and operating procedures in these operating instructions.
2.2 Meaning of the operating instructions
The operating instructions are to be read and followed by the responsible technical personnel before
mounting and start-up. As part of the check valves the operating instructions must be available close to it.
People could be seriously injured or killed if the operating instructions are not followed.
Read and observe the operating instructions before using the check valve.
Retain the operating instructions and make sure they are available.
Pass on the operating instructions to subsequent users.

4.9 Lifetime
The user is obligated to use Herose products only for their intended purpose.
In this case, a technical service life may be assumed in accordance with the underlying product standards
(e.g. EN1626 for shut-off valves and EN ISO 4126-1 for safety valves).
The technical service life can be restarted several times through the exchange of wearing parts within the
context of the maintenance intervals, and lifetimes of more than 10 years can be achieved.
If products are stored for a period exceeding 3 years, then the synthetic material components and
elastomer sealing elements fitted to the product should be replaced as a precautionary measure before
mounting and use.
