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.
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.
