Calibrating the level sensor
1.
Make sure the sensor is on. The green LED on the unit should be lid. The red LED indicates the signal
strength of the signal the unit sees. Under normal operation this let is on, if the red LED is not on the
sensor is not at the right angle or we are outside the 3-meter range.

Install the sensor in the desired location. Make sure there are no edge the sensor can see. If the
sensor sees sharp edges the reading will be off.

Pump start-up
Prime the pump before use. Open the inlet and outlet valves (if installed) to allow the pump to fill up with HOCl.
Open up some of the outlet to allow HOCl to “escape” the setup. Some pumps need to be primed by losing a vent
bolt. To find specifics on this type of priming please see pump manual. Turn on the pump and watch operation.
Make sure pump is running without excess noise.
System is now ready for operation.
