17 Commissioning
17.1 Checklist before commissioning
After installation and once the field settings are defined, the installer
is obliged to verify correct operation by performing a test run. See
the installation manual of the outdoor unit. Before executing "test
run" as well as before operating the unit, you must check the
following:
Installation – Control box
Check that the control box is properly installed to prevent
abnormal noises and vibrations when starting up the unit.
Installation – Expansion valve kit
Check that the expansion valve kit is properly installed to
prevent abnormal noises and vibrations when starting up
the unit.
Installation – Thermistors
Check that the thermistors are properly installed so that
they do not come loose.
Freeze-up prevention
Make sure thermistor R2T (liquid pipe) is installed on the
correct location to prevent freeze-up of the heat
exchanger of the air handling unit.
Field wiring
Check that the field wiring has been carried out according
to the instructions described in the chapter "15 Electrical
installation" [4 23], according to the wiring diagrams and
according to the applicable national wiring regulation.
Earth wiring
Be sure that the earth wires have been connected
properly and that the earth terminals are tightened.
Pipe size and pipe insulation
Be sure that correct pipe sizes are installed and that the
insulation work is properly executed.
17.2 To check during normal operation
When the test run was successful, an additional check needs to be
carried out during normal operation.
1 Close the contact T1T2 (ON/OFF) or start operation with a
remote controller.
2 Confirm functioning of the unit according to the manual and
check if the air handling unit has collected ice (freeze-up).
If the unit collects ice: see "18.2 Symptom: The AHU heat
exchanger is freezing up"[431].
3 Confirm that the fan of the air handling unit is ON.
NOTICE
▪ In case of poor distribution in the air handling unit, one
or more passes of the air handling unit may freeze-up
(collect ice). Put the thermistor (R2T) on this location.
▪ Depending on operation conditions (e.g. outdoor
ambient temperature) it is possible that the settings
must be changed after commissioning.
18 Troubleshooting
18.1 Solving problems based on error
codes
If the unit runs into a problem, the user interface displays an error
code. It is important to understand the problem and to take
measures before resetting an error code. This should be done by a
licensed installer or by your local dealer.
This chapter gives you an overview of most possible error codes and
their descriptions as they appear on the user interface.
