16.2 Replacing the desiccant capsules
Recommended interval: Depending on the level of air humidity at the station,
every 12 to 24 months and when replacing the batteries.
How to replace the desiccant capsules
Open the top cap/observation well cover.
Pull the communication unit approximately 80 cm out of the observation well
and hold (a second person would be useful).
Slide the pipe casing of the communication unit approximately 30 cm in the
direction of the pressure probe cable. (The rubber stop located on the pressure
probe cable (see Fig. 1) prevents the pipe casing from falling.)
Remove used desiccant capsules.
Install 2 new desiccant capsules.
Slide the pipe casing of the communication unit back on until it stops.
Slowly and carefully replace the communication unit in the observation well.
Close the top cap/observation well cover.
