Wintering
CAUTION:
The sensors should never stay dried during the winter in the pool
hose.
Sensors should be kept in a dry place, away from moisture in their
original packing.
A conservation agent is available from your installer. If you forget,
put tap water in the sensor cover, and store it in its original packing.
The lifetime of the sensors depends on the use and conservation.
In normal use, the duration exceeds three years. In case of poor
preservation or abnormal use, it can be reduced to a few months!
If these precautions are not taken, the sensors will not
operate next season.
