SELECT A LOCATION TO MOUNT WATER DETECTOR
• Select a location protected from water and other
precipitation. The case is water resistant, not water proof.
• Place the sensor in a dry, shaded area. Avoid locations with
direct sun, to prevent inaccurate readings.
• Fog and mist will not harm the sensor but direct precipitation
must be avoided.
• Note: Exposing the sensor case to extreme humidity may
temporarily disrupt data. The water detector with LCD should
not be submerged in water.
• Attach the H20 cable sensor to the Remote Water Detector
case and place it on the floor for water monitoring. Secure
the Remote Water Detector case in an area that is protected
from water. Once activated, the H2O/Dry readings will
display on the LCD.
• The H20 sensor on 6 ft. cable is not for use in a pool or hot
tub where chemicals may cause malfunction.
• Select a location within range of the Internet Gateway
(see “IMPORTANT SETUP & OPERATION NOTES”).
CONFIRM CONNECTION BEFORE MOUNTING
• IMPORTANT: Before permanently mounting…Test sensor
in the desired mounting location for at least 1 hour to
confirm good reception. Confirm consistent readings on your
account at www.lacrossealerts.com before permanently
mounting. Move the sensor closer to the Internet
Gateway if the signal is lost or not received.
• Mount the sensor after the activation process
