Replacing the cartridge of TGA and TGH filters
Note on intervals:
The operating conditions of cartridges with their respective fillings are
very specific and differ with regard to application. It is therefore
impossible to recommend any fixed intervals.
It is safest to determine the necessary exchange by measuring.
Please contact an authorised laboratory or the manufacturer for this
purpose.
Unscrew the lower housing and remove it.

Make the same preparations as described in section “Preparations” on
page 17.

Discard the housing O-ring.

Make sure the gas flows through the cartridge in the right direction (also see
the note on page 15).

Insert a new housing O-ring.

Apply a thin coat of grease on the housing threads before assembly if
