SERVICE INSTRUCTIONS

5.1  Service instructions for user

5.1.1  Visual inspection

The  visual  inspection  of  the  CMM is  recommended to  be done regularly. When making the  visual
inspection, check that:

·

  Instrument air consumption is correct, about 50 to 60 l/min

·

  Pressures are correct

·

  Sampling probe, sample lines and gas connectors are in good condition, no leakages or dirt

inside

·

  The color of instrument air dryer material is light

·

  Sample cell and evaporator temperatures are correct, 180

°

C

·

  Hg converter temperature is correct, about 700 °C

·

  Sample line temperature is correct, 180

°

C

·

  Cabinet temperature is correct, max ~30

°

C

·

  Air conditioning system is in good condition (A/C unit is clean of dust, temperatures are OK)

·

  There is no dust inside the cabin

5.1.2  Replacement of probe filter plate

The replacement frequency of the filters depends a lot on the quality of the measured sample gas. In
the beginning of the operation after installation, it is recommended to check the quality of the filter
quite often, so that the correct replacement frequency can be established.

1.  Do blowback.

2.  Switch off the measurement.

3.  Open the hood of the probe.

4.  Remove the filter carefully. 6 mm Allen key is needed to loosen the clamp.

5.  Clean or change the filter and run the points 1-4 in the reverse order.
