3.2 - INSTALLATION (see example in 3.4)
• Assemble the device by screwing it, with the due seals, onto the plant with pipes and/or fittings whose threads are consistent
with the connection being attached.
• Do not use the neck of the top cover (3) as a lever to help you screw it on, but only use the specific tool;
• The arrow, shown on the body (5) of the device, needs to be pointing towards the application;
• The regulator is normally positioned before the application. Previously evaluate the possibility of installing the regulator as
shown in the installation example in 3.4, namely in an optimal position pos.
• Should this not be possible, the following factors must be considered:
1. if installed as shown in pos.
2. if installed as shown in pos.
if installed in the optimal position
3. if installed as shown in pos.
regulator that protects it from debris that could enter from downstream from above (due to gravity);

• During installation, avoid debris or metal residues from getting into the device;
• To guarantee mechanical tension-free assembly, we recommend using compensating joints, which also adjust to the pipe's
thermal expansion;
• If the device is to be installed in a gas train, it is the installer's responsibility to provide suitable or correctly sized supports
to hold and secure the assembly. Never, for any reason whatsoever, leave the weight of the gas train only on the connections
(threaded or flanged) of the individual devices;
• In any case, after the installation check the tightness of the system, avoiding to subject the membrane of the regulator
(therefore, the downstream pipe section) to a pressure higher than 200 mbar;
3.3 - INSTALLATION IN PLACES WHERE THERE IS THE RISK OF EXPLOSION (DIRECTIVE 2014/34/EU)
The device is not suitable for use in potentially explosive areas.
