Function Test
Introduction
After connecting the free cooling unit, the display normally shows the current room temper-
ature.
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 pro-
vide 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.
Start a self-test
First check the home menu.
If the indoor and outdoor temperature sensors show unexpected temperatures
check their location and condition. Move or replace if necessary.
Check for any alarms.

To start a self-testcard press down arrow 4 times and then enter.
An automatic self-test can be carried out by pressing enter when the cursor is on Stop/start.
A manual test can be carried out by using the arrow buttons to navigate the menu to the
