11 Initial start-up

DANGER
Danger due to pressure and temperature range beyond permitted limits
Failure to observe this instruction may cause severe or fatal injury or damage to the
pipework.
Do not operate a valve whose approved pressure and temperature range is not sufficient for
the operating conditions - see section Intended use and markings on the valve. For an
application outside this range, consult the manufacturer, Mankenberg.
» For correct operation, the system pressure must be within the range of the marked
working pressure of the valve.
» In case of doubt, contact the Mankenberg service department.
For addresses, see the
The valve is supplied with no tension on the spring – hence no defined response pressure has been set in the
factory. During initial start-up, the valve must be adjusted to the system parameters.
The adjusting screw on the pilot valve should be tensioned for this purpose: Clockwise rotation (when looking
onto the adjusting screw) has the following effect:
on the pressure reducing valve: the outlet pressure increases.
on the back pressure regulator: the inlet pressure increases.
The set value to be set by means of the adjusting screw shall be defined by the operator of the system and must
be calibrated with the aid of a pressure gauge on the plant side (or some other pressure monitoring device).
NOTICE
Malfunction due to maximum or minimum setting of the adjusting screw
The valve opens or closes completely. The setpoint pressure range to be controlled is
exceeded. The pressures to be controlled exceed / fall below the specifications on the
nameplate.
» Never fully remove the adjusting screw
» Do not screw in the adjusting screw as far as it will go
NOTICE
At the beginning or shortly after initial commissioning, the screen or filter element of the filter
should be cleaned to prevent the filter from clogging.
NOTICE
After initial commissioning:
Check tightness of screwed body parts, re-seal if necessary. If necessary, consult
Mankenberg for tightening torques.
Check the leakage line for leaking medium.
