Mounting instruction

The switch is preferably mounted with the diaphragm in a vertical plane , unless the device is set or calibrated for horizontal mounting as on special customer models . On these models the mounting position is indicated on the side of the control .It may

be fastened directly to the duct , heater or panel as long as the mounting surface has minimal or no vibration .Pressure connection ns are marked +(high pressure ) and - (low or static pressure).For more informaton, please read the diagram on the side of the control .
