Cleaning the Condensing Chamber
The condensing chamber is located behind the front left hand panel of the
unit, and is accessible once the side panel is removed. The condensing
chamber is plumbed between the syringe and the needle (
Figure 19 on
page 99) and its purpose is to capture any solvent vapours extracted during
injection and to prevent the condensed solvent from reaching the syringe.
