5 Handling and maintenance
5.1 General
The 874 Oven Sample Processor requires appropriate care. Excess contam-
ination of the instrument may result in functional disruptions and a reduc-
tion in the service life of the sturdy mechanics and electronics of the
instrument.
Severe contamination can also have an influence on the measured results.
Regular cleaning of exposed parts can prevent this to a large extent.
Spilled chemicals and solvents must be removed immediately. In particular,
the mains plug should be protected from contamination.
5.2 Care
￭ Replace exhausted molecular sieve promptly. You should replace the
molecular sieve as soon as increased drift values appear in the Karl
Fischer cell.
￭ Check all tubing connections regularly for leaks.
￭ Flush out the tubing connections from time to time. Carefully dry the
tubing afterward. The tubing must be replaced after prolonged usage.
￭ Clean the sample insert regularly with a damp cloth.
￭ Replace the dust filter once a year.
