✦

To hold screws in place when assembling Radiation Shield.

OCATION

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

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.

3. Position the clip mounts over two of the mounting posts on the closed plate.

Make sure you orient the clip mounts as show in the ﬁgure 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.

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.

Do not attach the ﬁnal corner yet.

3. Place the cable clamp around the sensor cable approximately 4” (10 cm) from the T/H

Sensor.

4. Attach the cable clamp to the remaining corner of the T/H Sensor and to the closed

plate (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.
