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.
After installation and once the field settings are defined, the installer
is obliged to verify correct operation. Therefore a test run MUST be
performed according to the procedures described below.
17.1

Precautions when commissioning

CAUTION
Do NOT perform the test operation while working on
the indoor units.
When performing the test operation, NOT only the outdoor
unit, but the connected indoor unit will operate as well.
Working on an indoor unit while performing a test operation
is dangerous.
NOTICE
Be sure to turn ON the power 6 hours before operation in
order to have power running to the crankcase heater and
to protect the compressor.
During test operation, the outdoor unit and the indoor units will start
up. Make sure that the preparations of all indoor units are finished
(field piping, electrical wiring, air purge, ...). See installation manual
of the indoor units for details.
17.2

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
