Test report
Introduction
After connecting the free cooling unit, the display normally shows the current room
temperature.
The following test must be carried out to ensure that the system works. Each test phase
must be acknowledged with a signature and a date. This is to maintain the warranty and
to provide documentation prior to future servicing.
NB Before starting the unit, check that there is no protective paper blocking the filter. If
the filter is blocked, air flow is stopped and a filter alarm is given.
