Common procedures (threaded and flanged devices):
• In accordance with EN 161 a suitable filter must be installed upstream of a gas closing safety device;
• With outdoor installation, it is advisable to provide a protective roof to prevent rain from damaging the electrical parts of
the device;
• Prior to carrying out any electrical wiring operations, make sure that the mains voltage matches the supply voltage indicated
on the product label;
• Cut out power prior to proceeding with wiring;
• According to the plant geometry, check the risk of explosive mixture arising inside the piping;
• If the solenoid valve is installed near other devices or as part of an assembly, compatibility between the solenoid
valve and this other device must be evaluated beforehand;
• Avoid installing the solenoid valve near surfaces that could be damaged by the coil temperature;
• Provide a protection against impacts or accidental contacts if the solenoid valve is accessible to unqualified
personnel.
3.2 - INSTALLATION
(see example in 3.4)
Threaded devices:
• 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 coil (
11
) as a lever to help you screw it on, only use the specific tool;
• The arrow, shown on the body (
4
) of the device, needs to be pointing towards the application;
Flanged devices:
• Assemble the device by flanging it, with the due seals, onto the plant with pipes whose flanges are consistent with the
connection being attached. The gaskets must be free from defects and must be centred between the flanges;
• If, after installing the gaskets, there is still an excessive space in between, do not try to reduce the said gap by excessively
tightening the bolts of the device;
