7.3 Options
(refer to Fig. 2 page 4 and Fig. 10 page 11)
7.4 Function testing of diaphragm capsule
With a dry, cold diaphragm capsule the diaphragm surface with the circular bead must rest
against the top part of the wall (with 3 knobs), capsule is open (see Fig. 11).
If it rests against the bottom part of the wall, this is a sign that it is defective and must be
replaced with a new diaphragm capsule (see Fig. 12).
It should also be replaced if there are visible deformations on the surface.
ATTENTION !
Escape of hot medium under pressure!
Observe item 2.2!
Accumulated 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 possible to return the accumulating gases to the system by
connecting a pressure compensation line to the union
(pos. 52).
In Series 634 the residual condensate can be drained by way
of the drain plug (pos. 50) (see 5.1)
(standard in series 636/635).
Accumulated dirt and condensate can also be removed from
the hood (pos. 16) using a ball valve (pos. 56).
During operation it is imperative to observe general working
safety conditions and possibly fit devices to guard against
scalding/injury.
Note section 7.5 when installing and operating the option.
