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. Place the dryer tube with the used desiccant aside, but do not
discard.
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.

5. Secure the new dryer tube to the monitor.
6. Remove the black end cap from the dryer tube before re-
installing the monitor in the manhole.
Caution: If the cap is not removed, air will not be able to
enter the dryer tube, adversely affecting the pressure depth
sensor.
