16.3.1 CHANGE AND CLEANING OF THE BYPASS INJECTOR (180°C VERSION)

NOTE!

For cleaning the injector of the 180°C-vesion it is not necessary to remove it

out of the Bypass-T. Clean the nozzle mechanically or put the complete

cross into an ultrasonic bath. For the 320°C-version do not clean the com-

plete cross in an ultrasonic bath because the graphite packing could be de-

stroyed.

A cleaning with compressed air has to be carried out from the sample outlet

side (jet pipe).

We recommend the following steps for the change of the bypass injector:

 Unscrew the jet pipe (pos. 2) from the Bypass-T;

 Push out the injector nozzle from the opposite side (tool pos. 3, Fig. 18) and change it with

sealing;

 Push the injector into the T up to the block and press it tightly. Use the mounting tool.
