How do you use the reset switch?

There is a square switch situated under the black cover on the front-left of the appliance. Please make sure to push this button (it should make a beeping sound) when you first set up the LeveLuk or when replacing the filter. This allows for the correct display on the monitor (liquid crystal display) of all the information stored in the LeveLuk microcomputer. This reset button must be pushed in order for information to be displayed on the LCD screen. It notifies the user when there is too much or too little water, sets off an alarm when heated water passes through by mistake, and informs you to monitor the water flow. By using the reset switch correctly on the LeveLuk, you insure the delivery of safe and healthy water.
