outlet ports. Remove any dirt and clean the meshes. Unscrew the inlet
mesh, and clean it. If necessary, the bucket surface can be cleaned using
a mild detergent.
Rain Detector
Periodic Maintenance
Clean DRD11A at least once a year or more often in case the sensor
surface has become dirty.
- Clean DRD11A carefully with a soft lint-free cloth moistened with
mild detergent. Be careful not to scratch the glass surface.
- Check that the detector and the wind shield are free of ice and snow
deposits.
Ultrasonic Snow Level Sensor
During a severe storm event, Snow Level Sensor DCU7210 may fail to
detect the snow level. After the storm, the sensor will work properly.
CAUTION
Touch grounded metallic parts of the system with your hand before
touching the sensor plate of DRD11A. This will discharge possible
electrostatic load of your body to avoid damage to the sensor plate.
