Setting the bleed flow
On delivery, the bleed flow setting screw is set in
such a way that the double cone is not lifted.
To set a higher bleed flow, proceed as follows:

Turn the adjusting key (21) anticlockwise as far
as it will go.
The double cone is closed. No bleed flow is present.
The pressure gauge displays the upstream pressure
of the equipment.
 Turn the setting screw (7) clockwise until the
pressure gauge indicates a drop in pressure.
The double cone is now lifted slightly.
 Continue to turn the setting screw to set the
desired bleed flow.
As a rule, no more than a quarter to a half turn is
required. A full rotation lifts the double cone by
approx. 1.2 mm.

Set the outlet temperature as described on
page 15.


Block off the supply lines to the equipment.
