11 Commissioning
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 commissioning
and hand-over to the user.
INFORMATION
Protective functions – "Installer-on-site mode" . The software is equipped with
protective functions, such as tank disinfection. 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 36
hours 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 .

11.1 Overview: Commissioning
This chapter describes what you have to do and know to commission the system
after it is installed and configured.
Typical workflow
Commissioning typically consists of the following stages:
1 Checking the "Checklist before commissioning".
2 Performing a test run for the system.
3 If necessary, performing a test run for one or more actuators.
11.2 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.
