radiation shield to a Daytime Fan-Aspirated Radiation Shield.
The upgrade kit can be installed on any Vantage Pro2
™
or Vantage Pro2
Plus
™
Integrated Sensor Suite (ISS) equipped with a non-aspirated radiation
shield.
Components
The upgrade kit includes the following components:
Closed Cap Plate
Open Cap Plate
Open Plate
SIM Cover
Fan Plate

The kit also includes the following hardware:
Tools Needed
You may need some or all of the following tools to complete the upgrade:
• A medium Phillips-Head screwdriver
• A medium slot-tip screwdriver
• Other tools as required to remove and re-mount the ISS
• Cabled ISS Only: Wire cutters
Installing the Daytime Fan Kit
Installation Overview
These are the steps to install the Daytime Fan components:
1. For Consoles Only — Put the console into Setup Mode.
2. Take the ISS down from its installed position.
3. Disassemble the standard radiation shield.
4. Check Temperature/Humidity sensor orientation.
5. Assemble the lower section of the fan-aspirated shield.
6. Install the fan unit.
7. Assemble the upper section of the fan-aspirated shield.
8. Re-Install the ISS.
9. Take the console out of Setup Mode.
For Consoles Only— Put Console in Setup Mode
If you have a console, you need to put it in Setup Mode. This prevents the
reception of erroneous data while you are removing the ISS.
If you have an Envoy and are concerned with erroneous data, you may edit the
data via the WeatherLink software. See the WeatherLink Online Help for more
information.

To put your console in Setup Mode:
At your Vantage Pro2 console, press and hold DONE and then press the
down arrow (-) to put the console in Setup Mode. This prevents the
reception of erroneous data while you are removing the ISS.
Note: If the console acquires erroneous data during the upgrade, see Take the Console Out
of Setup Mode on page 15 for instructions on clearing data. Additional information on
clearing console data can be found in the Vantage Pro2 Console Manual.
Take Down the ISS
Please work on your Vantage Pro2 ISS in a safe place. If you are installing the
Daytime Fan Kit on an ISS that has already been placed into service, you will
need to take down the ISS from its sited location and move it to a convenient
and safe place to perform the installation.
To disassemble the ISS:
1. Locate the Sensor Interface
Module (SIM) housing cover
on the side of ISS and open it.
2. Disconnect the Solar Panel
wire on the SIM cover from
the SIM board by pulling the
Solar Panel connector.
3. Pull the foam insert out of the
cable access port in between
the cables and set the foam
insert aside.
4. Disconnect the anemometer
cable from the sensor
connector labeled WIND and,
if you are using a cabled
model, disconnect the console
cable from the SIM and slide
the cables out of the cable
access port.
5. You can now remove the ISS from its mounted position. Move it to a safe
place to install the kit components.
Disassemble the Standard Radiation Shield
Note: We recommend using a workbench or table to perform the following procedures.
1. Open and remove the SIM cover if you have not done so already.
2. Disconnect the Temperature/Humidity cable from the SIM and slide the
cable out of the cable access port.

3. Remove the rain collector cone from the ISS
base by rotating the cone counter-clockwise.
When the cone’s latches line up with openings
in the base, you can lift the cone off. The cone
fits in the base tightly and may require extra
pressure to remove the first few times.
Steady the ISS base between your knees when
removing the cone
4. Remove the three 8-32 x 4
'' screws
holding the radiation shield plates
together.
5. Save these three screws and
washers, and separate out the
radiation plating.
Depending on the placement of the
Temperature/Humidity sensor, you
may need to reorient the sensor
before assembling the lower section
of the radiation plating. See Check
Temperature/Humidity Sensor
Orientation on page 5 for more
information.

Check Temperature/Humidity Sensor Orientation
The orientation and placement of the Temperature/Humidity sensor should be
checked, and in many cases, should be reoriented. There are three ways the
sensor could be mounted in an ISS:
• On the second to bottom-most plate of radiation plating stack with the
Temperature/Humidity sensor facing up.
• Underneath the top plate of the radiation plating stack, on the insulating
disk with the Temperature/Humidity sensor facing down.
• On the second to bottom-most
plate of the radiation plating stack
with the Temperature/Humidity
sensor mounted on spacers,
facing down.
If the Temperature/Humidity
sensor is mounted on the second
to bottom-most plate with the
sensor facing down, it is in the
correct orientation and does not
need to be repositioned in the
stack.
If the Temperature/Humidity
Sensor is placed in one of the
other two positions, it should be removed from its current position and
remounted in the correct position shown above.
Reinstall the Temperature/Humidity Sensor — For Sensors Facing Up
1. Locate the
Temperature/Humidity sensor
on the second to bottom plate
in the radiation shield plating
stack.
2. Remove the three screws, flat
washer, and cable clamp
securing the
Temperature/Humidity sensor
to the radiation plating. Save
the small screw, flat washer,
and cable clamp for use later.
