6.1.1 Why change the Range configuration
a) If “TOO LOW” appears as the Flow on the gauge:

Increase Fan Pressure (restrict the flow) by installing a smaller Range configuration (e.g.
“TOO LOW” appears when using Range C8, put in two more Range plugs to change the
Range configuration to Range C6).

Make sure to record the new Range configuration in your notes/test form and in the
software.
b) If the fan is at 100% fan speed but the target induced pressure is not reached:

Decrease Fan Pressure (increase the flow) by installing a larger Range configuration (e.g.
the fan is running at 100% speed using Range plate C8, remove the C Range plate,
leaving the fan on Range configuration B).

Make sure to record the new Range configuration in your notes/test form, ad in the
software
6.1.2 Enter Test Fan data for each Range configuration used
Transfer the data from your notes/test form into the “Induced pressure” and “Test Fan” data
fields in FanTestic Integrity.
Add an additional “Test Fan” data set for each Range configuration change by clicking .
Enter the appropriate Fan Pressure data depending on which Range configuration was used. In
the example below, the first three Induced pressures were achieved with Range plate C8; the
next three Induced pressures required a smaller Range plate C6, and the Fan Pressure data are
therefore on a different line, since each line corresponds to a particular Range configuration.
6.2 Use the most current version of FanTestic Integrity
To determine the latest version, go to: http://www.retrotec.com/support/software-downloads and
click on the “Download” button beside the “FanTestic Integrity” item.

In the window that opens, the current version will be shown. Compare that to the version number
shown in the title bar when you open FanTestic Integrity. If they do not match, you need to update.

Note that using the “File” ”Check for Updates” can declare that your FanTestic Integrity is up to
date even when it is not in the following circumstances: you clicked “Skip update” when it was
offered at any point, or you are using the “ADMIN” version of the software. Note that these are
features of the Click-Once installer technology used for installing the software.
