3.4. Installation of pressure reducer unit
•
DANGER
Explosion hazard
Do not operate the analyser without pressure
reducer unit.
•
DANGER
Explosion hazard
The measuring point must not have an
overpressure of 150 mbar.
•
WARNING
As part of the safety concept, a reducing unit must be
installed on each Autocal inlet.
•
WARNING
As part of the safety concept, a reducing unit must be
installed on each sample gas inlet.
NOTE
The copper seal of the nozzle is intended only for
single use.
NOTE
Use PTFE strips to tighten the fitting inside the thread!
NOTE
The pressure reducer unit is equipped with a PTFE
DN4/6 fitting. Use a 1/8G outer thread fitting for using
another fitting.
For safety reasons, the gas inlet and the autocalibration inlet must be equipped
with a pressure reducing unit. This fitting prevents the gas flow from being
limited in the event of a pipe leak in the unit. The ventilation of the unit prevents
the creation of an explosive atmosphere. This is only guaranteed if the
overpressure at the measuring point does not exceed 150 mbar.
The sketch below shows how the pressure reducer unit is built.
