Shutdown Rate
If necessary, press STEP until you see the message:
Line leak detectors are required by law to shut down the submersible if the system detects a 3.0 gph (11.3 lph)
leak. Using this feature, you may program the system to shut down the submersible when it detects leaks of 3.0
gph, 0.2 gph (0.76 lph), or 0.1 gph (0.38 lph).
To accept a shutdown leak rate of 3.0 gph, press STEP, or press CHANGE until the desired shutdown rate
appears, then press ENTER. The system confirms your choice with the message:
Press STEP to continue.
Pumpside Test
If necessary, press STEP until you see the message:
After the system conducts a line leak test, the line leak detector also runs a pump side test for a pressure loss in
the piping and connections between the in-line check valve and the submersible pump.
Leak detection for components prior to the check valve must be provided. This can be done through use of VLLD
programmed pump side testing, installation of containment sumps and sensors, or other suitable means. Failure to
provide leak detection capability for components prior to the VLLD check valve could allow undetected product
leakage with possible contamination of the environment.
To accept ENABLED press STEP. Press CHANGE, then ENTER to disable the test. The system confirms your
choice with the message:
Press STEP to continue.
