5.3.2. Replacing Worn Desiccant

•DESICCANT BEDS ARE HOT DURING OPERATION.

To avoid burn hazard, make sure desiccant beds are sufficiently cool before replacing worn desiccant.

To access the Desiccant Bed:

1.Disconnect electrical power to the dryer.

2.Remove dryer side panels.

3.Remove any internal hoses that may be in the way.

4.Use nut driver to remove clamps at top and bottom of the desiccant tank.

5.Remove the Desiccant Cell leaving valve and Y-pipe attached to the dryer.

6.With a shop vacuum or by dumping, carefully remove all desiccant from each tower.

7.Inspect each lower desiccant screen for tears or holes where desiccant burned-through. Replace as needed.

8.After cleaning each chamber, add a level layer of half the 8 x 12 bead desiccant on top of the screen. Next, carefully add the full amount of bead desiccant specified per bed. Smooth the top level, and finally add another layer of the remaining bead desiccant to the top. Make sure this layer is level and smooth. (See following table for correct amount of desiccant required.)

9.Repeat the previous step for the other bed.

10.Inspect the gaskets on the valve assembly. Replace if necessary.

11.Place the desiccant cell assembly back into the dryer and replace clamps.
