Air Preparation System
CD10/AD and CD12/AD only: The tan colored beads are an air dryer desiccant. The blue and white media is typically called indicating media. It is silica gel and acts
as an indicator of the health of the air dryers.
If the air dryer desiccant requires replacement, moisture will be present in the dryer's output. The silica media will absorb the moisture and will change the blue crystals
to pink, then white. If the indicating media has changed color, this maintenance of replacing the media should resolve the issue and restore proper ozone output. If the
indicating media has yet to change color, it is recommended to replace the air dryer media for preventative maintenance. The indicating crystals can be saved for future
use, or installed; it is optional in this case.
For steps regarding replacement of these medias see "Air Dryer Desiccant Replacement" and "Indicating Media Replacement" below.
CD10 and CD12 only: Your air prep system will consist of either a PSA Oxygen Concentrator or LPSA Dry Air. Compressors, PSA Oxygen Concentrator or LPSA
Dry Air: Following the procedures outlined in the compressor rebuild kit, rebuild the two compressor heads and replace all filters.
Note: Manufacturers' recommended interval is 5,000 to 12,000 hours of operation. Compressor performance and/or operating conditions in the equipment area
will dictate the required frequency of this procedure.
Air Dryer Desiccant Replacement
Note: You will need to remove the unit from the wall in order to pour out the media. Allow the air dryer chambers to cool completely and read all steps before
continuing.
Step 1: Straighten out the ends of the dryer chambers using pliers.
Step 2: Using a snap ring tool, remove the top snap rings.
Step 3: Remove the top screens; the o-ring pick is handy for this. The bottom snap ring may be left remaining within the air dryer chambers.
Step 4: Turn the ozone generator over to pour the old sieve material from the dryer chambers and dispose. Note: When removing the sieve material, be sure not to
discard the bottom screens.
Step 5: Re-seat/Re-install the bottom screens. Note: The heater rod must be put through the center of the bottom screens.
Step 6: Fill chamber with new sieve material to 3/4" to 1" below the top of the dryer chambers. You will have more media than needed.
Step 7: Re-install the top screens.
Step 8: Using a snap ring tool, place the top snap rings snug against the top screen.
Step 9: Bend the ends of the dryer chambers in-ward for added retention of the sieve material (optional).
Step 10: The ozone generator must be turned on for 24 hours prior to system start-up to eliminate any moisture trapped in the new sieve material.
Indicating Media Replacement (CD10/AD only)
Step 1: Using wrench, loosen and disconnect the compression fitting located at the top of the indicating media chamber.
Step 2: With a flat-head screwdriver, unlock the two gray clamps securing the indicating media chamber.
Step 3: Pull the chamber free of the clamps, the chamber will only be held within the unit by the bottom cap. Rotate the chamber downwards to position the bottom cap
to be at the top of the chamber.
Step 4: Secure the bottom cap with channel lock pliers and turn the chamber counter-clockwise to unscrew it. Be mindful to not spill the indicating media.
Step 5: Remove the indicating chamber from the unit, remove the interior screen and dispose of the media.
Step 6: Remove the Teflon tape from the bottom cap's threads and re-tape the threads with 2-3 wraps.
Step 7: Refill the indicating chamber with new blue and white indicating crystals. You will have more media than needed.
Step 8: Replace the interior screen and reinstall the chamber following steps 1 through 4 in reverse order.
