19.2 Commissioning checklist
Note
This checklist for commissioning is solely intended to provide assistance to contractors. It is not exhaustive and is subject to
change and correction. Contractors are responsible for the services and work they have provided and must observe and comply
with the latest technical standards and generally accepted engineering standards.
Note
Read the operating and installation instructions of the appliances and the accessories carefully before use and retain them for
future reference. The checklist cannot replace careful reading of the operating and installation instructions.
