Commissioning

1. Confirm that the cover of the electrical cabinet of the connection kit is sealed well.
2. Conduct commissioning in accordance with the installation and use specification attached to the outdoor unit.
At the time of energization, because the electronic expansion valve will start initialization (open/ close), there may
be a click lasting for approximately 20 s, which is normal.
