Hold the lamp by the cylindrical glass body.
Soak a cotton tipped applicator in methanol from MSA PID Sensor Cleaning
Kit (P/N 10165248).
Rub the soaked swab on the surface of the Lamp lens in a circular motion
for 60 seconds.
Repeat process with a dry cotton tipped applicator.
Allow the lamp to dry for 30 minutes before proceeding with reassembly.
Place the lamp back in the sensor, making sure that the two metallized pads
are aligned with the corresponding excitation springs inside the sensor
cavity.
Using a dry cotton tipped applicator, press the lamp down firmly to seat in
the housing.
Be careful not to scratch the lamp lens.
With tweezers, reinstall the Cell Assembly. Align the three pins with the
corresponding sockets on the sensor and press this edge with a dry cotton
tipped applicator to seat the Cell Assembly. Make sure the Cell Assembly
is flush with the Lamp lens.
Place the Spacer back in the sensor housing, surrounding the Cell
Assembly.
Place both of the filters on top of the Cell Assembly. Make sure the Cotton
Filter is installed first, followed by the Teflon Filter.
The shiny side of the Teflon Filter should be on top.
