PREVENTIVE MAINTENANCE
Monthly Maintenance
Follow these steps monthly to test the Aqualeak 10K and verify that the device is functioning
properly. If your Aqualeak 10K is hooked into a BMS or NMS, notify monitoring personnel
before you begin to test the system.
1.
Place water on the sensor cable. Either dip the cable into a cup filled with water,
wrap the cable with a wet cloth, or pour a puddle of water onto the cable.
2.
Verify the “leak detected” alarm on the control
panel.
3.
Compare the distance reading on the Aqualeak 10K to a reference plan or map (if
available) to ensure the Aqualeak 10K displays the correct leak location. See page 30
for more information about calibrating the sensor cable.
4.
Dry the sensor cable and verify that the Aqualeak 10K returns to normal.
5.
Remove the End-of-Line terminator (EOL).
6.
Confirm the “cable break” (
cbr
) alarm on the Aqualeak 10K.
7.
Re-install the EOL.
8.
Verify that the Aqualeak 10K returns to normal.
9.
Monitor the cable current to ensure the cable is not being contaminated. The 10K will
alarm if the contamination is excessive. If the cable current is greater than 15
A,
troubleshoot the cables to determine which cable is contaminated. The contaminated
cable should be removed, cleaned, and retested.
