A4.1 Column/Desiccant Removal
Remove upper manifold as described in manifold section remove gasket retaining screws 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.
