Mounting to MAA 2000 slide rail immersion holder
•
Mount the slide rail immersion holder to the side wall of the basin or open channel using the
two predrilled holes. The adjustable stop should be on the bottom and the two sliding clamps
above.
•
Take the two sliding clamps off from the slide rail and mount them around the sensor housing.
Make sure that the clamps are placed on the two elevated ends of the sensor housing (one on
the upper part and one on the lower part, see figure above).
The two guide tracks have to line-up in one straight line to each other.
•
Slide the sensor with the two clamps into the slide rail. Make sure that the guide tracks of the
two clamps are properly seated.
•
Adjust the sensor position as necessary and fasten the adjustable stop.
