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.
