DAVIS Vantage Pro ISS Fan-Aspirated Add. 2003 & earlier - Manual (Page 8)

Page 8 Fan-Aspirated Radiation Shield
Wireless Vantage Pro
The solar-powered fan on the Wireless ISS will begin operating as soon as you
install the batteries. To prevent discharging the batteries, you should only
power the fan in a Wireless Vantage Pro immediately before mounting the ISS
in its final location.
1. On the Radiation Shield fan
plate, insert the O-ring in the
groove around the edge of
each battery compartment.
2. Insert a NiCad battery in each
compartment, matching the
plus (+) sign on the battery
with the plus (+) sign in the
battery compartment.
3. Verify that the fan is blowing
air up and away from the
Temp/Hum sensor.
4. Attach the battery covers to
the battery compartments
using two #4 x 3/8” (9.5 mm)
screws each.
Reassembling the Radiation Shield
1. Make sure the Temp/
Hum sensor cable runs
through the provided
cable channels and that
the fan unit is seated on
the fan plate.
2. Line up the threaded
rods on the upper sec-
tion of the Radiation
Shield with the mount-
ing holes in the lower
section.
3. Slide the two sections
partially together, leav-
ing enough clearance so
that you have access to
the Junction Board.
