HOSE CONNECTIONS

Note
All tube connections are equipped with 4/6 mm clamping ring tube fittings made of polyvinylidenfluoride (PVDF)
for gas inlet temperatures of up to a maximum of 80 °C [176 °F] (see chapter "9 Technical data"). When heated
sample lines are used, the gas inlet temperatures can increase up to a maximum of 180 °C [356 °F]. In this case,
the use of optional stainless steel bulkhead fittings is recommended.
Connecting tubes of dimension 4/6 mm are used as standard.
Install the sample gas tubes and the condensate tube as follows:
1. Remove the union nut from the clamping ring tube fittings by turning it anti-clockwise. The nut should
be removed from the thread with great care so as to ensure that the loose sealing ring in the nut is not
lost.
2. Place the union nut over the connecting tube.
3. Place the sealing ring over the connecting tube with the thicker bead towards the nut.
4. Place the tube over the nipple on the thread.
Note
5. The union nut is to be screwed tight by hand.
The hose will no longer be able to slip off and is now compression-proof.
The hoses are to be removed in the reverse order.
Warning

Do not switch tube connections; connections are marked accordingly.
After all lines have been connected, the tightness must be checked.
The tightness of the connections can only be guaranteed if the connecting
hose has a straight rim (hose cutter).
Aggressive condensate possible.
Wear protective glasses and proper protective clothing!
