COLUMN ASSEMBLY
SECTION
A4
A4.1 Column/Desiccant Removal
Remove upper manifold as described in manifold section and remove gaskets. The desiccant can now
be extracted from the column using a vacuum cleaner.
Bottom column bolts can then be removed and the column lifted clear
A4.2 Desiccant Replacement
Ensure columns are free from dust and that the lower manifold gasket is in good condition. Refilling
can now take place. In order to maintain dryer performance, the columns must be refilled using a snow
storm filling device which will achieve maximum packing density. The best results are obtained by
using a smooth and continuous operation.
