NOTICE
General commissioning checklist. Next to the
commissioning instructions in this chapter, a general
commissioning checklist is also available on the Daikin
Business Portal (authentication required).
The general commissioning checklist is complementary to
the instructions in this chapter and can be used as a
guideline and reporting template during the commissioning
and hand-over to the user.
NOTICE
ALWAYS operate the unit with thermistors and/or pressure
sensors/switches. If NOT, burning of the compressor might
be the result.
NOTICE
For models with integrated backup heater: The unit
contains an automatic air purge valve on the backup
heater. Make sure it is open. All automatic air purge valves
in the system (in the unit, and in the field piping –if any)
must remain open after commissioning.
For other models: The unit contains a manual air purge
valve. Make sure it is closed. Only open it when performing
an air purge.
INFORMATION
Protective functions – "Installer-on-site mode". The
software is equipped with protective functions, such as
room antifrost. The unit automatically runs these functions
when necessary.
During installation or service this behaviour is undesired.
Therefore, the protective functions can be disabled:
▪ At first power-on: The protective functions are
disabled by default. After 12h they will be automatically
enabled.
▪ Afterwards: An installer can manually disable the
protective functions by setting [9.G]: Disable
protections=Yes. After his work is done, he can
enable the protective functions by setting [9.G]:
Disable protections=No.
9.1 Checklist before commissioning
After the installation of the unit, first check the items listed below.
Once all checks are fulfilled, the unit must be closed. Power-up the

diagrams and according to the applicable legislation.
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.
There are NO damaged components or squeezed
pipes on the inside of the outdoor unit.
Only for models with integrated backup heater (F1B: field
supply), or if the external backup heater kit (F1B: factory-
mounted in the backup heater kit) is installed:
Backup heater circuit breaker F1B is turned ON.
Only for tanks with built-in booster heater:
Booster heater circuit breaker F2B (field supply) is

air purge valve (on the backup heater) is open.
For other models: The manual air purge valve is closed.
The pressure relief valve purges water when opened.
Clean water must come out.
The minimum water volume is guaranteed in all
conditions. See "To check the water volume and flow rate"
in "5.1Preparing water piping"[410].
(if applicable) The domestic hot water tank is filled
completely.
9.2 Checklist during commissioning

necessary).
9.2.1 To check the minimum flow rate
1 Check the hydraulic configuration to find out which
space heating loops can be closed by mechanical,
electronic, or other valves.
—
2 Close all space heating loops that can be closed. —
3 Start the pump test run (see "9.2.4To perform an
actuator test run"[438]).
