Fan high static pressure setting.
If the static pressure of the the outdoor unit fan increases, the airflow
decreases and the fan motor power input increases. The unit is able
to estimate the ESP via measurements.
Via this setting, the installer can set the ESP to a fixed level or
change the moment of ESP evaluation.
Note: For an ESP level higher than 45 Pa, level 0 is kept for
reliability of the fan motor.

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.
18.1

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.
18.2
