Fan-Aspirated
Integrated Sensor Suite (ISS) Retrofit Kit.
This retrofit kit applies to all cabled and wireless versions of the fan-aspirated
ISS.
Components
The Fan-Aspirated ISS Retrofit Kit includes the following components:
• Externally-mounted SIM with housing
• Temperature/Humidity sensor module
• Rain Collector cable extension
• New SIM Power cable
• Splice kit to attach extension cables
• Mounting hardware for new SIM housing
Tools for Setup
In addition to the kit, you will need the following tools:
• Small Phillips-head screwdriver
• Pliers or other crimping tool
• Other hand tools depending on your installation
Tip: If your Wireless Fan-Aspirated ISS has been in service for over a year, this would
be a good opportunity to replace the C-cell batteries used by the fan.
Installation Outline
Early version of the fan-aspirated ISS mounted the sensor interface module
internally inside the radiation shield. Newer versions of the fan-aspirated ISS
mount the SIM module in an external housing. The installation procedure for
the two different versions are outlined separately below.
CAUTION:
Please work on your Vantage Pro ISS in a safe place. We strongly recommend
that you remove the ISS from its installed position before beginning these steps.
