AQUALAB VSA
5. CLEANING AND MAINTENANCE
Keeping the AQUALAB VSA clean is vital to maintaining the accuracy of the instrument.
Dust and sampling debris can contaminate the sampling chamber, so regular cleaning
isessential. Instructions for cleaning the VSA desiccant cartridge and the sample chamber
are both in this section.
5.1 DESICCANT REPLACEMENT
During a test, if the VSA determines that a desiccant tube has exhausted its drying capacity,
it automatically switches to the other desiccant tube. When this event occurs, a message
appears indicating that the exhausted desiccant tube needs to be replaced.
1. Removal of the desiccant material.
a. Orient the desiccant cartridge or tube (Figure 24) so the lid or cap is up.

b. Remove the main lid.
c. Remove the foam located below the lid as shown in Figure 25.
