Cleaning the Radiation Shield
The outer surface of the radiation shield should be cleaned when there is excessive
dirt and build-up on the plates. Use a damp cloth to clean the outer edge of each ring.
Note: Spraying down or using water excessively to clean the radiation shield can damage the sensitive sensors
or alter the data the ISS is transmitting.
Check the radiation shield for debris or insect
nests at least once a year and clean when
necessary. A buildup of material inside the shield
reduces its effectiveness and may cause
inaccurate temperature and humidity readings.
1. Using a Phillips head screwdriver, loosen the
two #6 x 2

tion shield plates together, as shown.
2. Taking care to maintain the order in which the
five plates are assembled, separate the plates
as shown and remove all debris from inside
the shield.
3. Reassemble the plates in the same order in
which they were disassembled, and fasten
them together using a Phillips head screw-
driver to tighten the #6 x 2

Cleaning the Rain Collector, Debris
Screen, and Tipping Spoon Module
To maintain accuracy, thoroughly clean the rain collector cone and debris screen as
needed or at least once a year.
Note: Cleaning the rain collector and tipping spoon may cause false rain readings. See “Clearing Data Col-
lected During Testing and Installation” on page 10.
1. Use a damp, soft cloth to remove any debris from the rain collector and debris
screen.
2. Use pipe cleaners to clear any debris remaining in the screen.
3. When all parts are clean, rinse with clear water.
