To thoroughly clean the 24-Hour Fan-Aspirated Radiation shield and
Temperature/Humidity Sensor:
Tools and supplies needed:
•
Adjustable wrench
•
Soft, damp cloth
•
Soft brush (such as a toothbrush)
•
Small Phillips head screwdriver if you are also replacing the fan batteries
You will not need to remove the mounting bracket from the pole or post on which it is
mounted. You will be able to remove the entire radiation shield so that you can clean it
and access the temperature/humidity sensor, the fan, and the fan batteries.
Tips: If you are out in the field where it is very dusty, place the radiation shield on a convenient
work place, such as a table, a piece of cardboard, or a pickup truck tailgate.
Note:
Take note of the cable placement and routing as you disassemble the shield so you can replace
them correctly.
1. Disconnect the sensor cable.
2. Using an adjustable wrench,
remove the three hex nuts, lock
washers, and flat washers
connecting the mounting bracket
to the solar panel bracket and
radiation shield.
3. While removing the hex nuts and
washers, support the radiation
shield from the bottom. When
the hex nuts and washers are
removed, it will drop.Take care
not to lose the washers and nuts.
4. Place the radiation shield on a
workspace.
5. Lift off the solar panel bracket
(with the solar panel cable still
connected).
