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.
