    Outdoor unit Transmission wiring commissioning checklist is also available on the Daikin Business Portal (authentication required). In case the safety measures demand a ventilated enclosure, the BS unit test run has to include a measurement of the actual extraction The general commissioning checklist is complementary to airflow rate to confirm that it meets the legal requirements.
  • Page 39: About Airflow Requirements

    17 Commissioning NOTICE It is very important that all refrigerant piping work is done before the units (outdoor, BS or indoor) are powered on. When the units are powered on, the expansion valves will initialise. This means that the valves will close. If any part of the system has already been powered on, setting [2-21] on the outdoor unit has to be activated to open the expansion valves.
