T
RUN AND FINAL CHECK
EST
The installer is obliged to verify correct operation of unit after
installation.
Final check
Before switching on the unit, read following recommendations:
■ When the complete installation and all necessary settings have
been carried out, close all front panels of the unit and refit the
unit cover.
■ The service panel of the switch box may only be opened by a
licensed electrician for maintenance purposes.
Note that during the first running period of the unit,
NOTE
required power input may be higher than stated on the
nameplate of the unit. This phenomenon originates
from the compressor that needs elapse of a 50 hours
run in period before reaching smooth operation and
stable power consumption.

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 50°F (10°C), which might activate
the freeze-up protection and thereby prevent the test run to finish.
Should the water temperature drop below 50°F (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 "Error
codes" on page 39.
When the unit is put into pump down operation, the
NOTE
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).

If required, the installer can perform a manual test run operation at
any time to check correct operation of heating, cooling and domestic
water heating.
