TECHNICAL FEATURES
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).
INSTALLATION
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).
Make sure that the pipes are clean and aligned so the
regulator/governor is not under stress.
Do not remove the perforated diaphragm breather cap (3) and do not
obstruct the hole, otherwise the regulator/governor will not work.
Install the governor so avoiding contact with plastered walls.
Make sure that the regulator/governor is suitable to the intended
use.
