Fan-Aspirated ISS Installation Options
Batteries
The Wireless Fan-Aspirated ISS is solar powered and is supplied with two
NiCad C-cell batteries that come pre-installed. The following options for
battery power exist:
• Use two fan batteries for maximum length of overnight aspiration but
with slightly lower average daytime aspiration.
• Use only one fan battery for some overnight aspiration but with slightly
higher average daytime aspiration.
• Remove both batteries for maximum daytime aspiration and no night-
time aspiration.

Fan-Aspirated ISS Maintenance

• Keep the surfaces clean, since the Fan-Aspirated Radiation Shield is
less effective when the surfaces are dirty. Remove dust from the solar
panel and the shield with a damp cloth.
• Remove any debris obstructing air flow through the radiation shield,
e.g., leaves, twigs, webs, and nests.
• Avoid spraying insect killer of any kind into the radiation shield as this
may damage the sensors and the shield.
• Once a year: replace the motor (Part # 7758), batteries, and remove any
debris lodged inside the unit.
Disassemble the Radiation Shield
Disassemble the radiation shield for routine cleaning, maintenance, and to
replace the batteries and motor. To disassemble the shield:
