Replacement of Desiccant Column
The desiccant column has a minimum expected life of 12 weeks. The column consists of
molecular sieve interspersed with silica gel, viewable through the window on the side
of the generator. The column should be replaced when all of the silica gel has visibly
darkened.
1. To replace the column,
depressurise the generator and disconnect power.
Lift the
hinged lid back, then unscrew the column cap anticlockwise to remove.
2. Next withdraw the inner tube and dispose as per your company’s hazardous waste
disposal policy. The new column may now be inserted into the outer collar.
