Daytime Fan-Aspirated Radiation Shield Kit Installation Manual For Vantage Pro2™ & Vantage Pro2 Plus™ Stations Introduction The instructions describe how to upgrade a non-aspirated Vantage Pro2 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.
Installing the Daytime Fan Kit The kit also includes the following hardware: #8-32 x 3-1/4" Screws (3) #8 Split-Lock Washers (6) #8-32 x 1/2" Screws (3) Threaded Spacers (3) #8 Flat Washers (6) 12" Cable Ties (2) Daytime Fan Kit 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 Installing the Daytime Fan Kit Installation Overview T
Installing the Daytime Fan Kit 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 16 for instructions on clearing data. Additional information on clearing console data can be found in the Vantage Pro2 Console Manual.
Installing the Daytime Fan Kit 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 Twist to Open Remove the Rain Collector Cone 4. Remove the three 8-32 x 4'' screws holding the radiation shield plates together. 5.
Installing the Daytime Fan Kit 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.
Installing the Daytime Fan Kit 3. Reinstall the sensor face down on the radiation plate, using the two 1' spacers and #4 screws included with the kit. 4. Put the cable clamp back on the cable and use the screw and flat washer to resecure the cable onto the radiation plate. 5. Replace the radiation plate back in its correct place in the radiation shield plating stack.
