When the diaphragm capsule is dry an cold, the diaphragm must be in contact with the top
part of the wall as shown in „Fig. 6 : Capsule OPEN“.
If the diaphragm is away from the top surface, and/or in contact with the bottom part of the
wall as shown in „Fig. 7 : Capsule CLOSED“, the capsule is defective and should be
replaced.
ATTENTION !

Observe item 2.2 !
Accumulated dirt and condensate can be removed from the
hood (Pos. 16) by opening the pressure screw (Pos. 46.1).
When opening, hold against the blow down ball valve
(Pos. 46).
Accumulating inert gases can be discharged to the
environment with the manual air vent valve (Pos. 51) by
opening the pressure screw (Pos 51.1).
It is also possible to return the accumulating gases to the
system by connecting a pressure compensation line to the
union (Pos. 52).
During operation it is imperative to observe general working
safety conditions and possibly fit devices to guard against
scalding/injury.
