Setting: Time to clean air filter
This setting must correspond with the air contamination in the room.
It determines the interval at which the TIME TO CLEAN AIR FILTER
notification is displayed on the user interface. When using a wireless
user interface, you must also set the address (see the installation
manual of the user interface).

8 Commissioning
8.1 Overview: Commissioning
This chapter describes what you have to do and know to
commission the system after it is installed.
Typical workflow
Commissioning typically consists of the following stages:
1 Checking the "Checklist before commissioning".
2 Performing a test run for the system.
8.2 Precautions when commissioning
INFORMATION
During the first running period of the unit, the required
power may be higher than stated on the nameplate of the
unit. This phenomenon is caused by the compressor, that
needs a continuous run time of 50 hours before reaching
smooth operation and stable power consumption.
NOTICE
Before starting up the system, the unit MUST be energised
for at least 6hours to avoid compressor breakdown during
startup.
NOTICE
NEVER operate the unit without thermistors and/or
pressure sensors/switches. Burning of the compressor
might result.
NOTICE
Do NOT operate the unit until the refrigerant piping is
complete (when operated this way, the compressor will
break).
NOTICE
Cooling operation mode. Perform the test run in cooling
operation mode so that stop valves failing to open can be
detected. Even if the user interface was set to heating
operation mode, the unit will run in cooling operation mode
during 2‑3 minutes (although the user interface will display
the heating icon), and then automatically switch to heating
operation mode.
NOTICE
If you cannot operate the unit in test run, see "8.5 Error
codes when performing a test run"on page18.
WARNING
If the panels on the indoor units are not installed yet, make
sure to power OFF the system after finishing the test run.
To do so, turn OFF operation via the user interface. Do
NOT stop operation by turning OFF the circuit breakers.
8.3 Checklist before commissioning
Do NOT operate the system before the following checks are OK:
You read the complete installation instructions, as
described in the installer reference guide.
The indoor units are properly mounted.
In case a wireless user interface is used: The indoor unit
decoration panel with infrared receiver is installed.
The outdoor unit is properly mounted.
There are NO missing phases or reversed phases.
The system is properly earthed and the earth terminals
are tightened.
The fuses or locally installed protection devices are
installed according to this document, and have not been
bypassed.
The power supply voltage matches the voltage on the
identification label of the unit.
There are NO loose connections or damaged electrical
components in the switchbox.
The insulation resistance of the compressor is OK.
There are NO damaged components or squeezed
pipes on the inside of the indoor and outdoor units.
There are NO refrigerant leaks.
The correct pipe size is installed and the pipes are
properly insulated.
(1)
Field settings are defined as follows:
▪ M: Mode number – First number: for group of units – Number between brackets: for individual unit
▪ C1: First code number
▪ C2: Second code number
▪ : Default
(2)
Fan speed:
▪ LL: Low fan speed
▪ Setup volume: The fan speed corresponds to the speed the user has set (low, medium, high) using the fan speed button
on the user interface.
