			==== Installing screen filter ====
			Screen filter is mounted on the measuring probe of sensor to protect measuring probe electrodes from mud and water. Using the filter extends significantly faultless lifetime of the sensor.

			Screen filter mounting order: firstly put on fixator, then put on bottom stop and fix it with two side screws. Put the screen filter over bottom stop and fasten it with a fixator locks.

			* Put the sensor into the tank and fix: when fixing with rivets, use a rivet driver when bolting, put on a seal (per bolt), a spacer and a spring washer when fixing to plastic tanks with wall thickness over 3 mm, use vendor furnished self-tapping screws and a seal (per self-tapping screw)

	* Cut the sensor's measuring probe so that its length is 25 mm less than the depth of the tank. Ensure that shearing line is perpendicular to the sensor longitudinal axis		* Cut the sensor's measuring probe so that its length is 25 mm less than the depth of the tank.
