Aggressive vapours (e.g. by means of formic
acid or acetic acid, ammonia, amine or
ammonia compounds, aldehydes, phenols,
chlorine, tannic acid etc.) in the vicinity of the
windows must be absolutely avoided.
–
Never use acetic-acid or cross-linked acidic
sealing compounds or those with the above
mentioned contents, since both the direct
contact with the sealing compound and its va-
porisation can attack the hardware’s surface .
–
Due to the risk of salt deposits on the hard-
ware, shorter maintenance and lubrication
intervals are necessary in coastal areas
(every three months).
