Some instruments do not have the vapor select valve fitted. However your service representative
can easily connect these instruments to an external vapor system.
Connecting to an External System
Use the following procedure to connect the instrument to an external vapor system.
1. Connect the instrument’s vapor outlet into the external system (see item 2 in Figure 18).
2. Turn the vapor select valve a quarter turn anticlockwise to direct vapors to the vapor outlet
(see Figure 19).
Note: to access the valve you may need to remove a blanking plug.

3. Set the carbon filter threshold to one of the following options.
(i) The inspection interval for the external system (see 6.2.1 Instrument Settings).
(ii) The maximum value (1000) to limit the number of unwanted warnings (see 6.2.1
Instrument Settings).
(iii) Overridden (contact your service representative to arrange this setting).
WARNING
When the vapor select valve is in the external position, you must ensure an external vapor
system is correctly installed or potentially dangerous fumes will be released into the laboratory
environment.
