Mounting
The sensor must be mounted with the wire terminal blocks oriented to the lower right and the
sampling chamber in a vertical position. Failure to mount the sensor in this fashion may result in
false or inaccurate readings and can allow water to enter the housing and destroy the sensor.
Wall Mount.
Use locally available wall mounting hardware, such as molly-bolts or toggle bolts, to firmly affix the
sensor to the wall. The sensor should be mounted using the mounting feet mounted on the back of
the housing. Ensure that all four sets of mounting feet are accessible. Hold down the mounting feet
with the locally available wall mounting hardware.
Pole Mounting.
The sensor can be mounted to a support pole by utilizing Uni-Strut type C braces. Attach the C-
braces to the back of the housing, perpendicular to the sensing chamber direction. Attach clamps to
the C-brace and run stainless steel band straps around the pole and through the straps.
Cable Runs.
All cabling must avoid running parallel to high voltage (48 VDC or greater or any AC voltage
wiring). Cable must be greater than 12 inches away from high voltage wiring or conduit. Avoid
running cable near any inductive load, such as motor, fluorescent fixture, transformer. Depending
upon local codes, sensor cabling may be run loose or be placed into conduit used exclusively for low
voltage control wiring.
Sensor cable shall have the minimum specifications:
-For cable runs of 0 to 1000 feet
18 AWG, 3 or 4 Stranded Wire.
