6  Installation

6.1  General points

 NOTICE

All work on the device may only be carried out by trained and professionally
qualified staff.
During all work, care must be taken that everything remains absolutely
clean.

6.2  Mechanical installation

 DANGER

Hazard caused by breakage or fluids spurting out

If the device is blocked it acts like a closed gate. The uncontrollable pres-
sure levels that occur in this case can result in damage to the device and
to the upstream system elements. For this reason, use of a pressure limiter
upstream from the device is essential.
It must be taken into consideration that the whole fluid flow must be dis-
charged via the pressure limiting device.

 DANGER

Hazard caused by breakage or fluids spurting out

Only connections and pipes approved for the pressure range to be expected
may be used.
The respective manufacturer's regulations must be heeded.

 CAUTION

Hazard caused by hot surfaces

The user is to take measures against unintended contact at temperatures
above 60°C.
