OCATION
T
IPS
✦
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 upwards.
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.

NSTALLATION
I
The Radiation Shield may be mounted in four basic orientations: 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), on top of a wood post, or onto Davis’ Sensor
Mounting Arm. Each of these configurations is pictured below. You should
determine ahead of time which orientation best suits your purpose because the
installation instructions differ slightly depending on how you plan to mount
the Radiation Shield.

The Radiation Shield can house the External Temperature Sensor, Stainless
Steel Temperature Probe, or External Temperature/Humidity Sensor.
Attaching the External Temperature Sensor or the Stainless Steel
Temperature Probe to the Radiation Shield
In order to attach the External Temperature Sensor or the Stainless Steel 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 self-threading screws, three
#4 flat washers, and the temperature sensor/probe.
Note: The following illustrations show the installation process for the External Temperature Sensor. The
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.

5. Once secured, adjust the position of the sensor so the sensor and approximately 1/4”
(6 mm) of cable protrude from the clip mounts.
6. Place the cable clamp around the sensor cable approximately 8” (20 cm) from the
sensor.
7. Secure the cable clamp to one of the remaining mounting posts (using a #4 x 1/2” pan
head self-threading screw and a #4 flat washer) so that a loop of cable is formed.
Make sure to mount the clamp with the flat side up and the bulge side
down. Tighten the screw completely so that the cable cannot move within
the cable clamp. If using the Stainless Steel T emperatur e Pr obe, wrap a cable
tie around the sensor and cable as shown below to hold the probe in place.

Attaching the Temperature/Humidity Sensor to the Radiation Shield
In order to attach the External Temperature/Humidity Sensor (T/H Sensor) to
the Radiation Shield, you will need a closed plate, four #4 x 1/2” pan head
self-threading screws, one # 4 flat washer, and the T/H Sensor.
1. Position the T/H Sensor over the four mounting posts on the closed plate, lining up the
holes in the mounting posts with the holes in the T/H Sensor’s casing.
Make sure you orient the T/H Sensor as shown in the figure below (with the
long side of the sensor parallel to the long side of the plate).
2. Using three #4 x 1/2” pan head self-threading screws, attach THREE CORNERS of the
T/H Sensor to the closed plate.

Attaching the Support Plate to the Cover Plate
To attach the support plate, you will need the cover plate, the support plate,
three #8 x 2 3/4” pan head screws, three 1” spacers, three #8 flat washers, thr ee
#8 split lock washers, and three #8 hex nuts.
1. Slide the three #8 x 2 3/4” pan head screws up through the non-threaded holes in the
shield support plate.
Make sure the side of the support plate marked “UP” is in fact on top as you
slide the screws in from the bottom.
2. Place the cover plate over the screw ends protruding from the support plate.
3. Place a 1” spacer over each of the screw ends.
4. Secure the support plate and spacers to the cover plate using a #8 flat washer, #8
split lock washer, and #8 hex nut on each of the screw ends.
Tighten until the support plate is firmly attached to the cover plate.

Assembling the Plates and Studs
To assemble the plates and studs you will need the cover plate assembly as
well as the flat plate and closed plate with sensor, three #8 x 5” threaded studs
with attached #8 push nuts, three #8 flat washers, three #8 split lock washers,
and three plastic retainers.
1. Slide each of the three #8 x 5” (127 mm) threaded studs, with push nuts installed,
through each of the three holes in the closed plate, flat plate, support plate and cover
plate.
When inserting the threaded studs make sure that the short end (when measured from the push nut) goes through the plates. Screw the short end of the
threaded stud in until the cupped side of the push nut bottoms inside the
recess of the closed sensor plate. Tighten as much as you can by hand.

The instructions for assembling the Radiation Shield differ slightly if you plan
to mount the Radiation Shield on top of a wooden post. Follow the instructions
below if (and only if) you plan to ultimately mount the Radiation Shield on top
of a wooden post.
Attaching Mounting Bracket
To attach the mounting bracket you will need a closed plate, the mounting
bracket, three 1/2” spacers, three #8 x 2 3/4” pan head screws, six #8 flat washers, three #8 split lock washers, and three #8 hex nuts. You will also need a drill
with a 3/16” (4.7 mm) drill bit.
Note: Y ou will need to supply three #8 x 1” screws if you plan to mount the Radiation Shield over the top of
the post (not preferred), instead of suspending it over the side edge.
MOUNTING ON TOP OF A POST
1. Using the power drill with 3/16” (4.7 mm) drill bit, drill three holes through one of the
closed plates in the locations marked by the small dimples on the bottom of the plate.
Do not use the closed plate to which you attached the sensor.

2. Place a #8 flat washer over the end of each of the #8 x 2 3/4” pan head screws.
As long as the extra length of screw end protruding from the bottom of the
Radiation Shield doesn’t create clearance problems when mounting the
Radiation Shield, you can use the 8 x 2 3/4” pan head screws. If a clearance
problem exists, you will need to use #8 x 1” screws instead (not included).
3. Slide the three #8 x 2 3/4” pan head screws (with washers) up through the holes you
just drilled.
4. At this point, you may want to place a small piece of tape over each of the screw heads
to keep the screws in place as you continue.
5. Place a 1/2” spacer over each of the screw ends protruding from the closed plate.
6. Slide the mounting bracket over the screw ends protruding from the closed plate.
7. Secure the mounting bracket to the closed plate using a #8 flat washer, a #8 split
lock washer, and a #8 hex nut on each of the screw ends.
Tighten until the mounting bracket is firmly attached to the closed plate.

MAINTENANCE INSTRUCTIONS
✦ The effectiveness of the Radiation Shield will be reduced if the surfaces of the
shield become dirty.
Wipe the surfaces of the shield using a damp cloth to remove dirt etc.
✦ Keep areas between Radiation Shield plates free of debris that may obstruct air
flow e.g., leaves, twigs, webs, nests.
DO NOT remove nesting insects or animals by spraying insect killer of
any kind into the radiation shield because this may damage the sensors
and the Radiation Shield.
