5. MALFUNCTIONS AND THEIR RECTIFICATION
Malfunctions can largely be avoided if installation and commissioning have been properly carried
out, if maintenance work is regularly undertaken, and if original Katadyn replacement parts are used.
Only authorised personnel may rectify malfunctions and handle the system whilst conforming to the
relevant safety regulations.
If the measures taken fail to rectify the malfunction, the authorised Katadyn customer service
department should be contacted immediately.

DECOMMISSIONING

Katadyn filters can be taken out of operation for extended shut-down periods without any risk, and
can be re-used at a later date. The following measures must be taken to do this, and the instructions
given in section 6.1 must be observed.

6.1 Decommissioning Procedure

Empty the filter completely.
Clean and dry the filter elements.
When dis-assembled, filters must be stored in a non-corrosive, dry atmosphere.
During the storage period, no maintenance is necessary.
A prolonged shut-down period has no effect upon the functional efficiency of Katadyn filter systems
and elements because the systems contain no movable parts.
