Replacement / Disposal of Desiccant (continued)
 Remove plug from the desiccant fill (ON SMALL TOWERS
WITH THREADED DESICCANT FILLS).
 The tower can be blown clean with an air hose or may be
washed out with a water hose, if desired, but time must be
allowed if this is done to completely dry the tower before
refilling it with desiccant.
 Replace drain plug in bottom of the tower.
 Refill the chamber with the specified desiccant. Refer to the
Specifications in Section 5 for required desiccant quantity.
 Do not tamp the desiccant.
 Replace the manway cover components or the pipe plug
and tighten.
 Repeat process for the other tower.
 Make sure all drain and fill ports are in place and properly
tightened. Soap test for leaks before returning the dryer to
service.
 Slowly repressurize the dryer and turn on.
For HC dryers with a mixed desiccant bed
 If a mixed bed with molecular sieve is required, the
activated alumina should be installed on the bottom of the
drying bed with the molecular sieve on the top.
