ATTENTION!
The gas maximum pressure admitted is
50mbar. To supply the gas with an higher pressure, even for short time, may damage the valve.
The gas distribution system must be realised in compliance with the rules in force and it must respect the sections and the pressure suitable for the installed equipment. .
Look to the following picture: before the machine must be installed a rapid gas interceptor cock (1); the gas cock must be near the dryer and in an easy reachable position. The cock must comply with the rules in force and must be an approved model.
A low point pressure switch must be provided (2). The connection to the gas system must be made using a no-vibration joint (3); if flexible tubes are used, these must be in stainless steel DIN 3384 or DIN 3383.
