7. Carefully disconnect both sides of the filter from the pump manifold.
8. Remove the old filter and replace with a new filter ensuring that the filter connectors are fully engaged in the
manifold ports and that the filter is the correct way round (arrow pointing downwards).

10 PYROLYZER MODULE OPTION
The pyrolyzer module option is installed underneath the standard MIDAS
®
gas detector. The air sample is drawn
through the pyrolyzer to the sensor cartridge. The pyrolyzer converts Nitrogen Trifluoride (NF
3
) present in the air
sample into Hydrogen Fluoride (HF) by means of pyrolysis. The HF can then measured by the sensor cartridge
and the concentration displayed as the equivalent reading in ppm NF
3
. Contact Zellweger Analytics for the
availability of other detectable gases using the pyrolyzer module.

WARNING:
To maintain stated sensor performance when using the pyrolyzer, ensure the constant ambient temperature
and humidity levels of the installation point do not exceed the maximum operating temperature and
humidity range. This product can tolerate temporary changes in temperature and humidity, but constant
exposure to higher levels of temperature and humidity will require more frequent bump testing or calibration
to confirm working specification.
