Level the Solar and UV Sensors
If you have an sensor suite that includes a solar radiation and/or UV sensor, use the
bubble level on the sensors as a guide to verify that the sensors are level.
Adjust the level by tightening or
loosening the three screws that hold
each sensor onto the shelf. Make
sure that the sensor diffusers are not
shaded by the rim of the rain cone.
For the UV sensor, make sure the
entire comb structure is above the
rim of the rain cone.
For the Solar Radiation sensor,
make sure the top of the sensor
body is even with or above the rim
of the rain cone.
Note: If you are installing the solar or UV sensors separately, see the Solar Radiation and UV
Sensor installation manual for more information.
Start the 24-Hour Fan
If your sensor suite has a 24-Hour Fan-Aspirated Radiation Shield, the batteries are
factory installed with plastic tabs between the batteries and the contacts. This
prevents batteries from draining during shipping.
The two clear plastic tabs
extend out from the largest disk
in the radiation shield. Pull
them out to start the fan.
Note: The Daytime Fan (as in product number 6334) does not use batteries.
Tip: If the sensor suite has been in storage for an extended period, the fan batteries may need to charge in
sunlight for a few hours.
