13.2 PNEUMATIC CONNECTIONS
When using the universal filters F...-...-D and the flow chamber LS , two screw connections with thread
G 1/4" a and corresponding hose or tube connection must be used for the connection of sample gas
lines. The fittings must be screwed into the universal filter or the flow chamber with PTFE tape.
The
LS25 flow chamber already has screw connections for 8 mm tubes.
For mounting the tube or hose lines:
•
Remove the union nuts as well as the pressure and cutting rings from the screw connection.
•
Slide the union nut, then the pressure ring, then the cutting ring onto the tube or hose.
•
Insert the hose or tube into the fitting and tighten the union nut hand-tight.
•
Tighten the stainless steel nuts hand-tight, then tighten them with a flat spanner exactly 1 1/4
turn. The stainless steel nuts are then correctly mounted.
