SUPPLY CONNECTIONS

14.1

HOSE/TUBE CONNECTIONS

The gas inlet and outlet hoses/tubes of versions CG-2/-2M are connected on the rear of the converter.
Here, the standard executions provides G 1/4" threaded joints. The versions CG-2H-W/-2MH-W as wall
mounting execution with heated sample gas inlet and outlet are equipped with a 6 mm tube connector
of stainless steel.
The appropriate tube or hose threaded joint connections are available optionally from M&C.
N O T E !
When connecting the sample gas supply hoses or tubes to the corresponding threaded connections,
pay attention to the following points:
N O T E !
• Loosen the sleeve nut of the clamping-ring threaded joint by turning to the left. Take care that the nut
is removed carefully from the body of the threaded joint to avoid losing the clamping ring which is
mounted loose in the nut.
• Push the sleeve nut over the connection hose/tube.
• Push the clamping ring respectively the pressure and the cutting ring onto the connection hose/tube
with the thicker bulge pointing to nut.
• Push the hose/tube onto the supporting nipple in the threaded joint.
• Tighten the sleeve nut by hand.
The hose/tube is now mounted in such a way that it cannot slip and is resistant to pressure.
Connecting a heated sample line with an inner tube of PTFE to the converters CG-2H-W/-2MH-W, a
respective insert is absolutely necessary.

Do not confuse hose/tube connections for sample gas inlet and out-
let; the connections are labelled accordingly!
Check for tightness after connection!
The tightness of the connections can only be guaranteed if the end
section of the connection hose/tube is flat (use a hose-cutter)!
