INAL CHECK AND TEST RUN

Final check

Before switching on the unit, read the following:
When the complete installation and all necessary settings have
been carried out, be sure that all panels of the unit are closed. Is
this 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.
In order to purge most of the air out of the system perform a pump
operation as described below:
1 Change field setting [E-04]
The default value is 0.
When changing the setting to 1, the pump will operate at low
speed (pump only, the unit will not operate).
When changing the field setting to 2, the pump will operate at
high speed.
2 When air purging is finished, change the field setting back to 0.
It is the responsibility of the installer to make sure that the air is
purged out of the unit and system.
NOTE When using thermostatic radiator valves, make sure to
open all valves during air purging operation.

Test run

NOTE When the indoor and outdoor unit are powered on for
the first time, an initialisation takes place. This will take
maximum 12 minutes.
When using the
initialisation, an error code (UH) will be displayed.
The installer is obliged to verify correct operation of the indoor and
outdoor unit after installation. Therefor a test run must be performed
according to the procedures described below. At any time it is
possible to check correct operation of space heating and domestic
water heating.
NOTE During the first start up of the unit (the first 48
hours of compressor running), it might happen
that the noise level of the unit is higher than
mentioned in the technical specifications. This is
not an abnormal event.
Start up of the unit in space heating mode is only
possible when the outdoor ambient temperature is
lower than 20°C. Refer to
admission" on page 23
