You should properly dispose of any discarded desiccant.
Consult local disposal regulations for more information.
Inspect each lower desiccant screen for tears or holes where desiccant burned-through.
Replace as needed.

screen. Next, carefully add the full amount of bead desiccant specified per bed. Amounts are
listed in the Desiccant Amounts Table below. 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.
