Replacing the cartridge of TGA and TGH fi lters
Note on intervals:
The operating conditions of cartridges with their respective fi llings
are very specifi c and differ with regard to application. It is therefore
impossible to recommend any fi xed 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 15.
▶ Unscrew the cartridge with the O-ring and discard it.
▶ Discard the housing O-ring.
▶ Insert a new cartridge with O-ring and hand-tighten the cartridge.
▶ Make sure the gas fl ows through the cartridge in the right direction (also see the
note on page 13).
▶ Insert a new housing O-ring.
▶ Apply a thin coat of grease on the housing threads before assembly if necessary.
Use only TG 1 thread grease unless any other grease has been agreed upon in
the order!
▶ Make sure during assembly that
— the O-rings are properly seated
— the grease does not come into contact with O-rings and sealing surfaces.
Both housing parts have marking arrows.
▶ Connect both housing parts again and hand-tighten them until the marking
arrows match.
▶ Close the manual drain valve again.
▶ For ATEX-compliant fi lters:
Ensure conductivity, test and document it.
Check the housing for tightness.
Check well running of threads
There is a risk of threads seizing when a fi lter made of aluminium, steel or stain-
less steel is stored.
▶ Make the same preparations as described in section “Preparations” on page 15.
▶ Open the fi lter at regular intervals, e.g. every 6 months.
▶ Check whether the threads are still suffi ciently greased and well running.
▶ Apply a thin coat of grease on the housing threads before assembly if necessary.
Use only TG 1 thread grease unless any other grease has been agreed upon in
the order!
▶ Connect both housing parts again.
