MAINTENANCE

The safety instructions specific to the plant and process are to be consulted prior to any maintenance
work!
W A R N I N G !
It is difficult to give any recommendations as to a particular maintenance cycle. Depending on your
process conditions, a meaningful maintenance cycle must be elaborated for the specific application.
An indication that filter-maintenance may be necessary could be shown by a constant decline in the
amount of sample gas in the analysis system.
Filter maintenance is restricted essentially to replacing filter elements and checking seals.
The filter element has to be replaced as follows:

Remove cover lid.

Open the clamps of the aluminium heating body and remove the lower part.

Unscrew the glass of the filter by turning left.

Screw out the filter's knurled screw and replace filter element. (If more than 70% of the filter
has changed colour, it must be replaced!)

Check filter element seals and replace if necessary.

Clean filter chamber.
Assemble the filter in reverse sequence. The lower part of the heating body is supplied with 2 pins for
easy assembling. The pins must fit to the two holes in the upper part of the heated body.

Aggressive condensate is possible.
Wear protective glasses and proper protective clothing!
High surface temperatures!
Touching the filter surface can cause serious burns!
Wear protective gloves and protect the filter of unauthorized
access!
Prior to carrying out maintenance work on electrical parts, mains
voltage should be disconnected from all poles!
This also applies to any external control circuits, which may be
connected.
