Page 11: Specific Installer Safety Instructions
WARNING Make sure installation, servicing, maintenance, repair and applied materials follow the instructions from Daikin and, in addition, comply with applicable legislation and are performed by qualified persons only. In Europe and areas where IEC standards apply, EN/IEC 60335-2-40 is the applicable standard. - Page 12 Specific installer safety instructions WARNING When using safety shut-off valves, make sure to install measures such as a bypassing piping with a pressure relief valve (from liquid pipe to gas pipe). When the safety shut-off valves close and no measures are installed, increased pressure may damage the liquid piping.
- Page 13 Specific installer safety instructions WARNING If the supply cord is damaged, it MUST be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard. Commissioning (see "19 Commissioning" [ 72]) WARNING If the panels on the indoor units are not installed yet, make sure to power OFF the system after finishing the test run.
