Tools and Materials Needed
• Small Phillips-head screwdriver and medium slotted-head screwdriver
• Wrench or pliers
• Drill with 3/16” (4.7 mm) drill bit
To drill pilot holes if attaching radiation shield to the top of a post.
• Adjustable wrench or 11/32” (8.6 mm) wrench and 7/16” (10.9 mm) wrench
To tighten hex nuts (11/32” wrench) or to drive lag screws into wall or post (7/16”
wrench).
1
• Four 1/4” x 1 1/2” (38 mm long) lag screws
To attach radiation shield to a post or wall.
• Three #8-32 x 1” (25 mm long) screws
To attach radiation shield over the top of a post (if the provided #8 x 2 3/4” pan
head screws create clearance problems).
• Tape
To hold screws in place when assembling the radiation shield.
Location Tips
• The radiation shield works best when in a location with a steady breeze. Mount
away from fences, buildings, trees, or other obstructions.
• Install over plants or soil if possible.
• Do not install over or near sprinklers. The radiation shield is not designed to
protect the sensor from water sprayed upward.
• If attaching to a building, the preferred location would be on the north side in the
Northern Hemisphere and on the south side in the Southern Hemisphere.
Installation Options
The radiation shield may be mounted in three basic configurations: on the side of a
wooden post or a wall; on a metal pipe with outside diameter between 1” and 1 1/4”
(25 mm and 31 mm); or on top of a wood post. Each of these configurations is
illustrated below. Each orientation requires slightly different installation.

Attach the Sensor
Use the radiation shield to house an external temperature sensor (Temperature
Probes with RJ Connector, p/n 7817 or 6477; or Stainless Steel Temperature
Probes: with RJ connector, p/n 6475 or with Two-Wire Termination, p/n 6470).
In order to attach the temperature probe to the radiation shield, you will need a
closed plate, both clip mounts, the cable clamp, three #4 x 1/2” pan head, selfthreading screws, three #4 flat washers, and the temperature probe.
Note: Illustrations show a Temperature Probe with RJ Connector.
1. Place the sensor cable into the notch on one of the clip mounts and hold it in
place. Make sure to hold the clip mount so the raised semi-circle at the top of
the notch faces up.
2. Position the second clip mount over the first, with the notch facing in the
opposite direction, securing the sensor cable between the two notches.
When positioning the second clip mount, make sure the raised semi-circle
faces down.
Clip Mounts
3. Position the clip mounts over two of the mounting posts on the closed plate.
Make sure you orient the clip mounts as shown in the illustration below.
4. Attach the clip mounts to the mounting posts using two of the #4 x 1/2” pan
head self-threading screws and two of the #4 flat washers.
