Installation example
Deaeration of the chambers of the diaphragm regulator: Before setting the installation into operation, the diaphragm regulator has to be deaerated. This is done by loosening the two vent screws situated at the highest point of the regulator (if necessary, the diaphragm regulator must be repositioned…
