3. Place a flat washer over the end of each screw and insert it into the body.
4. Place a spring over the end of each screw and hold the springs in place using a #6
screw retainer.
5. Secure the sensor to the bracket by driving the screws into the appropriate holes as
shown below.
If mounting the sensor on the tilting bracket in a location under 46˚ latitude
or in a situation which requires the angle of the tilting bracket to be less than
28˚, you will need to use the standoffs supplied with the tilting bracket. Con-
sult the Sensor Tilting Bracket manual for details.

6. Position the Sensor Mounting Arm so it is pointed in the direction of the sun at solar
noon.
Solar noon occurs halfway between sunrise and sunset; consult your local paper
or the WeatherLink
®
software for sunrise and sunset times. To correctly align
the arm, screw a mounting screw part way into any of the sensor’s screw posi-
tions on the mounting arm and rotate the arm until the shadow from the screw
is parallel to the edge of the sensor arm at solar noon.
7. Attach the bracket to the mounting arm as described in the Sensor Tilting Bracket
instruction manual.
If you are installing both the solar radiation and the UV sensor on the sensor
tilting bracket, make sure you mount the solar radiation sensor on the sen-
sor tilting bracket before attaching to the sensor mounting arm.
