3.1 Installation must be performed by personnel with the requisite expertise and who have
received the appropriate training and instruction on safety engineering.
3.2 All components of the shut-off unit are tested for correct functioning and leak-tightness
prior to delivery. All apertures are closed off.
3.3 Before commencing installation, check that connections and threads are undamaged
(possibly by briefly blowing them out). If damage is ascertained, the extension must not
be connected.
3.4 Remove the sealing plug (not shown here) of the distributor block (2) and screw in the
NPT fitting (3) of the connection pipe (4) in its place. To do this, wrap PTFE tape (Teflon
tape, Part No. 0321422) with 7 times in anti-clockwise direction, leaving the first thread
turn free and pressing the end of the tape down tightly. Screw the parts together so that
the connection is gastight.
3.5 Connect the extension (5) to the pre-assembled connection pipe (4). Here, to ensure
adequate stability of the Ermeto screwed connection, it is essential to tighten the pre-
assembled union nut (6) in a professional procedure.
3.6 Attach the baseplate of the extension (5) and cylinder brackets (not shown here) to the
wall using the screws provided.
3.7 Place the cylinders in front of the bracket and secure with safety chain or strap.
3.8 When all screws, screw fittings and connections have been tightened, slowly supply the
system with gas and carry out leakage testing on all newly installed, gas-bearing
connections.
4.1 For safety reasons, repairs must be carried out in authorised workshops, by the
manufacturer or suitably qualified personnel.
4.2 Only original spare parts may be used.
4.3 After every repair, the panel must be checked for correct functioning and leak-tightness.
4.4 The manufacturer accepts no liability for repairs not effected in authorised workshops, if
the panels are modified or if non-original spare parts are used, and in such cases, the
warranty is rendered null and void with immediate effect.
4.5 The system should be tested for correct functioning and operational safety once per year
by the manufacturer.
4.6 Annual inspection of the flashback arrestors and other safety devices attached to the
tapping points downstream of the pressure control panel is prescribed by law. The
operator must provide verification of this.
