142 Operating instruction SCK Gas Sampling System OI/SCK-EN Rev. E
Check the duct opening for clogging at regular intervals and clean if neces-
sary.
Note: Inserting the gas sampling probe when the duct opening is clogged can
lead to damage to the probe. The same applies to re-inserting the gas sam-
pling probe after prolonged standstill of the sampling system.
Owing to the greater flow speeds in this process, after start-up the gas sam-
pling probe must be checked frequently for wear at the calcinator gas outlet
measuring point. If distinct signs of wear are visible after a short time, check
the installation position of the gas sampling probe. Failing to observe this can
lead to severe damage or total loss of the gas sampling probe.
