FILTER MAINTENANCE
Said operation must be performed by skilled personnel.
Check the filter at least once a year!
The filter can be changed without removing the train. If the filter is replaced frequently, it is best to replace
the fastening screws, too.
The maintenance procedure is as follows:
cut off the gas flow by closing the gate;
unscrew the screws and remove the filter cover;
remove the filter and replace it with a new one;
refit the cover, screw it on and tighten screws without overtightening;
test operation and check for leaks.
WIRING SCHEME,
ATTENTION
Before starting any work, the system's power
supply must be cut off.
