Prepare the Temperature/Humidity Sensor
Rotate the Mounting Bracket
To facilitate packing and shipping the
Temperature/Humidity Sensor, the
mounting bracket is installed upside down
at the factory. For best air flow through the
shield as well as ease of installation, we
suggest you flip it over.
1. Place the Temperature/Humidity
Sensor on a table or level work
surface.
2. Remove the three sets of hex nuts,
lock washers and flat washers that
hold the mounting bracket and the
solar panel bracket together as shown
in the illustration. Be careful not to
lose the small nuts and washers.
3. Remove only the mounting bracket, flip it over and replace it on the solar bracket.
4. Fasten the mounting bracket in place by replacing the hex nuts and washers.
Start the fan
The 24-hour fan batteries are shipped with pull tabs that prevent draining the batteries until
ready to use. Pull the tabs. You should hear the fan come on.
Before You Install the Temperature/Humidity Sensor
Choose a Location
It is important to remember to choose a location that best represents the environment you
would like monitor and/or protect. Consider the following factors as you choose a location:
• In the Northern Hemisphere, the solar panel should face south for maximum sun exposure.
In the Southern Hemisphere, it should face north.
• Do not mount the sensor near any source of cold or heat that might distort temperature
measurements.
• Mount so that the screened opening at the bottom of the radiation shield is not blocked and
air can move up into the shield.
• Mount the sensor over vegetation or soil if possible.
• Do not install over or near sprinklers, which may inflate humidity values.
For Frost Monitoring Locations
• Place the sensor at about 5' (1.5m) in a grassy, open field that receives the coldest
temperatures adjacent to the area at risk of frost damage.
