14.4 Leak proof test
With the leak proof test the system is checked by the device (incl. the condensate separator) up to
the probe spike on undensity. The internal gas pump generates in addition a subpressure which is
measured over the built-in draft sensor and is observed for a period of 10 seconds. Based on the
decrease of pressure the leakness of the system will be determined.
Operation:
•
The leak proof test cap # 61382 (for probe tubes Ø 8 mm) must be put on on the probe
spike.
ATTENTION:
The probe spike before the density test clean!
(With depositions on the tube the cap does not seal.)
•
Launch under “extras” the leak proof test on which the following window will pop up:
OK
…
If of the leak proof test is not passed the probe must be checked including the hosing as well as
the condensate separator.
If no undensity is ascertained in these external parts the COSA 707 Combustion Analyzer has to
be checked in a service department
(worldwide service departments see www.cosaxentaur.com).
