LEAK DETECT
The leak detect feature indicates if solution is present in the pump head by sensing the
conductivity of the liquid. When a leak is detected, the pump shuts off, the relay closes,
and the display flashes LEAK.
The sensitivity is factory preset to distinguish between water and common water treatment
chemicals. The sensitivity is adjusted with the potentiometer (brass screw) located under
the terminal cover on the back of the pump. A small flat blade screwdriver, less than
3 mm, is needed to turn the potentiometer. To reduce false leak detections, always
calibrate the pump with the chemical and concentration utilized in the application.
To reset, the tube housing, cover & leak detect components must be clean, dry, and free of
chemical residue. The power must be disconnected and reconnected to resume operation.
