Replace the dryer tube or the desiccant contained within the dryer
tube on a regular basis or as necessary. Desiccant can absorb
moisture only when it is blue in color. Pink desiccant indicates that
it can no longer absorb moisture. Therefore, if the desiccant
appears either colorless or pink upon inspection, replace the dryer
tube or desiccant immediately.
Replacing the Dryer Tube
Replace the pressure depth sensor dryer tube (ADS p/n 3704-0032)
in the following way:
1. Clip the cable ties securing the dryer tube to the monitor.
2. Cut the clear flexible tubing running from the dryer tube to the
pressure depth sensor connector at a location close to the brass
barbed fitting on the dryer tube.
3. Set aside, but do not discard, the old dryer tube with the used
desiccant.
4. Attach a new dryer tube to the pressure depth sensor by
inserting the brass barbed fitting into the open end of the plastic
tubing running from the sensor connector. Make sure the
tubing seats firmly against the fitting to prevent air or moisture
transfer.
