Chapter 2 
Maintenance

 

Under conditions of normal use, this Sampler should require 

little maintenance. Depending on the frequency of use, periodic 

cleaning and cheks for correct performance are recommended.

Tube Holder

Replace the Tube Holder when it shows signs of wear or  

damage. If filter is not clogged or cracked, it may be used in 

 

the new tube holder if it is inserted so the flow through is in 

 

the same direction. The stainless steel washer must be placed on 

the holder before reinstalling the pressure plate. To remove the 

tube holder or to change the filter in the tube holder, remove the 

four phillips head screws located on the green pressure plate.

Foam Filter

The round, black floam filter on the back of the GEMINI Sampler 

prevents dust from entering the unit. This filter can be easily 

removed, cleaned and replaced or replaced by a new foam filter. 

Ten extra foam filters (P/N 497715) are supplied with the unit.

Filter Disc

Periodically remove the Filter Disc for cleaning or replacement.
