Setting the stage one flow rate
·
Unscrew the locking screw without
touching the painted screw opposite.
·
Rotate crown D clockwise by hand
(without using a tool): the flow rate
will decrease and vice versa.

·
Turn it around and use it as a
spanner.

Rotate it in the direction of the:
- arrow : the progressive rate will
increase
+ arrow : the progressive rate will
decrease.
Particular case
Nominal flow stage setting
This is necessary only if the flow stage
read under a pressure of 40daPa on
the controller is too high.
Do as follows:
·
loosen the locking screw avoiding to
touch the opposite painted screw.
Plug
C has a 4.5-turn travel length.
·
Make the screw rotate in a cw
direction
arrow - :
the flow stage decreases and vice
versa.
It might be necessary to adjust the
pressure.
·
Tighten the locking screw back up.
Gas pressure switch setting
·
Remove the transparent cover.
The device includes an index
x
and
a graduated mobile disc.
·
Adjust the pressure switch temporarily
at the minimum value read on the
graduated disc.
Controller setting:
Controller pressure measurements are
carried out at
pBr .
The pressure setting provides the
desired flow rate.
