Compensation diaphragm, operating diaphragm and safety diaphragm: an external breather outlet pipe is not necessary as the incorporated safety diaphragm ensures that, in the event of breakage of the operating diaphragm,no gas leakage (over 30 dm3/h) is
possible inside the room (in compliance with par.3.3.2. EN88 specifications).
Install the governor with the diaphragm positioned horizontally (on horizontal pipes). Be careful to follow always the direction of gas flow indicated by the arrow on the regulator/governor.
Suitable tools must be used for the regulator/governor fitting on the inlet and outlet hubs. Never effect leverage on the sleeve of the upper cover when fitting the regulator/governor.
For all models with the filter inside, the regulator/governor is best fitted at a comfortable height from the ground so as to faclitate the filter cleaning (fit always a suitable gas filter upstream the governor/regulator).
