Particulate filter replacement
The particulate filter is used to remove larger particles of VOC’s as
they can after time block the inlet
to the PID sensor, thus making the sensor read erratically or not read at all.
The procedure for changing the particulate filter is as follows:
1]
Unscrew the filter from both of the male and female luers attached to the 6mm
pipework from the inlet manifold.
2]
Reverse the above process to fit a new filter.
