REMOVING AND REBUILDING DESICCANT

SEALING PLATE

Before the desiccant cartridge can be replaced

or rebuilt the desiccant sealing plate must be removed.

It is recommended that all non-metallic parts be replaced

when the plate is removed.

In the past, three methods

have been employed to secure the desiccant sealing

plate to the desiccant cartridge; a Tru Arc retaining ring,

two special thin nuts and the latest method a single hex

lock nut.

Removing the securing device will permit the

desiccant plate to be separated from the desiccant

cartridge.

After removing the desiccant cartridge:

1.

Remove the two o-rings from the desiccant plate and

discard them.

2.

Remove the ball check valve retaining clip and

remove and discard the rubber ball valve.

3.

Clean the desiccant plate thoroughly using a quality

commercial solvent making sure the purge orifice

and check valve seat are clean.

4.

Install new ball check valve and replace the retaining

clip and screw (Fig. 7)
