EST RUN AND FINAL CHECK
The installer is obliged to verify correct operation of the indoor and
outdoor unit after installation.

9.1. Final check

Before switching on the unit, read the following recommendations:
■
When the complete installation and all necessary settings have
been carried out, be sure that all panels of the unit are closed. If
this is not the case, inserting your hand through the remaining
openings can cause serious injury due to electrical and hot parts
inside the unit.
■
The service panel of the switch box may only be opened by a
licensed electrician for maintenance purposes.

9.2. Automatic test run

When the unit is put into operation (by pressing the
the first time, the system will automatically perform a test run in
cooling mode. The test run will take up to 3 minutes, during which no
specific indication is given on the user interface.
During the automatic test run, it is important to ensure that the water
temperature does not drop below 10°C, which might activate the
freeze-up protection and thereby prevent the test run to finish.
Should the water temperature drop below 10°C, press the h/c
button so the h icon is displayed. This will activate the backup heater
during the automatic test run and raise the water temperature
sufficiently.
If the automatic test run has ended successfully, the system will
automatically resume normal operation.
If there are misconnections or malfunctions, an error code will be
displayed on the user interface. To resolve the error codes, see
"11.3. Error codes" on page 48.
NOTICE
When the outdoor unit is put into pump down operation
(see the outdoor unit installation manual), the automatic
test run flag will be cleared. The next time the system is
put into operation, the automatic test run will be executed
again.
After finishing automatic test run or power ON/OFF, the
compressor will operate in the selected operation mode
and continue for certain time (set point on the remote
controller is overruled during this operation).
