Changing the Exhaust
Collector Tube
The exhaust collector of the InKjel P consists of a glass
collector tube that conducts the exhaust gas from the
sample vessels to the suction hose, and the steel hous-
ing. If the glassware part should get broken you need
not replace the exchaust collector as a whole but just
insert a new collector tube.
Danger of injury in case of breakage of
glass! Always adhere to your professional
association's regulations when handling
glass elements! The new collector tube
comes ready with the PTFE plates mounted
already, so do not try to remove the PTFE
plates from the broken tube.
Caution: there may be sulphuric acid in
the exhaust collector! It might burn you.
Adhere to the current Hazardous Sub‑
stances Ordinance!
If it has not yet been done, rinse the exhaust collector
with water to remove any residues of acid.
Pull the suction hose off the nozzle of the exhaust
collector.
Lay the exhaust collector to the edge of the desk so
one of the red handles comes to lie beneath the desk,
but make sure the exhaust collector won‘t slide off the
desk.
The glass collector tube is mounted to the roof of the
housing with two pipe clips. Two pieces of silicone hose
are inserted each between the glass tube and the hous-
ing and between the glass tube and the pipe clips, as
buffers. On unscrewing the four screws holding the pipe
clips, the collector tube gets free.
Unscrew the four screws on the roof of the exhaust
collector.
Take the pipe clips and the silicone buffers off the col-
lector tube.
Carefully take the collector tube out of the housing.
You need to tilt the collector tube to get the suction
nozzle out of the gap of the housing.
Lay two new silicone buffers out in the housing, on
the places where the collector tube is to be held by
the pipe clips. Depending on the size of the collector
tube this may be between the outer or the other two
screwholes.
Insert the new collector tube into the housing in such
a way as for the suction nozzle to go through the gap
of the housing, and lay it on the silicone buffers.
