5.2.4 Gas lines blowing
Blow gas lines after their cleaning (section 5.2). To blow gas lines switch the instrument into the
CWA module calibration mode and leave it in this mode for about an hour. The instrument can
produce false chemical alarms. Switch the CWA module off in an hour.
5.3 Test of the micropump capacity
Connect the lower silicone tube of the rotameter (available as an option) with the outlet (11)
(Figure 3.2), check that a seal is made tight.
Switch the instrument into the CWA module calibration mode. The rotameter should read no less
than 0.4 l/min.
If this is not the case, clean the micropump (refer to section 5.2.3), and retest the micropump
capacity.
If this test failed, send the instrument to the manufacturer or authorized service center for
the micropump replacing.
