Installing the Daytime Fan Kit Put Console in Setup Mode 1. At your Vantage Pro console, press and hold the DONE key and then press the key to put the console in Setup Mode. This prevents the reception of erroneous data from the rain collector while you are removing the ISS. Note: If the console acquires erroneous data during the upgrade, refer to “Take the Console Out of Setup Mode” on page 14 for instructions on clearing data.
Disassemble the Standard Radiation Shield Note: We recommend using a workbench or table to perform the following procedures. 1. 2. 3. 4. 5. Turn the ISS upside down with the rain collector cone on the bottom. Disconnect the RAIN cable and, if present, disconnect the SUN and UV cables from the SIM. Wireless ISS Only: Disconnect the solar power cable. Turn the ISS right-side up with the cone on top. Remove the rain collector cone from the ISS base by rotating the cone counter-clockwise.

Assemble the Upper Section 1. 2. Place the open cap plate (has hole in center) on top of the fan plate, then place the closed cap plate (no hole). See Figure 18. ‘ Upper Shield Assembly” on page 12. Place the solar panel bracket on top of the stack with the panel located near the hinge side of the SIM housing. Line up the screw bosses in the radiation shield stack with the solar panel mounting bracket holes. See Figure 16. Solar Panel Mounting Bracket Radiation Shield Mounting Holes (3) Figure 16.
Insert this screw first #8-32 x 3-1/4" Screws (3) 5. 6. 7. Lower the ISS base onto the stack so that the screw goes into the boss nearest the solar panel.Turn the screw a few times to engage the threads. Place a lock washer and washer on the other two 3 1/4” screws then insert them through the remaining two screw holes. Tighten all three screws to securely fasten the radiation shield and solar panel bracket to the ISS base.
Re-Install the ISS 1. Install the rain collector cone and turn the ISS upside down. Open the SIM cover and connect the TEMP/HUM and RAIN sensor cables. If installed on your station, connect cable for the UV and SUN sensors. 2. 3.
