Commissioning

NOTICE
General commissioning
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
Make sure the automatic air purge valve in the hydraulic
block is open.
All automatic air purge valves must remain open after
commissioning.
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 hours they will be
automatically enabled.
▪ Afterwards: An installer can manually disable the
protective functions
protections=Yes. After his work is done, he can
enable the protective functions by setting [9.G]:
Disable protections=No.
