Mounting to telescopic rod immersion holder
• Mount the flexible mounting bracket on an existing handrail or on a separate holder, diameter
32...50 mm/1.3...2.0" or square 28...42 mm/1.1...1.7". The bent lip on the mounting plate shall
be on top and faced toward the liquid or tank.
• Adjust the mounting bracket to the correct angle and tighten the nuts.
i The bracket shall be fixed to the rail, and must not be able to rotate around it.
• Disassemble the rod holder and place it around the telescopic rod.
• Use the SS screws on the rod holder to tighten the rod holder to the rod.
• Pull the cable and hose through the sensor holder and rod.
• Connect the sensor to the rod with the two piece black PVC sensor holder.
• Tighten the adapter halves until snug, which will leave about 1.5 mm/0.06" gap.
The gap is required so the water can drain from the rod.
• Adjust the length of the telescopic rod as necessary by twisting the nuts while holding the rod.
Do not extend the rod sections beyond the black lines. This could lead to rod damage.
