Page 4: General Notes
Operating Instructions FRQS-4/10/16A General notes 1 General notes 1.1 Structure of the operating instructions Before installation and start-up, read this manual carefully to ensure correct use! We emphasize that these operating instructions apply to specific units only, and are in no way valid for the complete system! Use these operating instructions to work safely with and on the device. -
Page 5: Intended Use
Operating Instructions FRQS-4/10/16A Safety instructions 2.1 Intended use The equipment is to be used solely for the purposes specified and confirmed in the order. Other uses which do not coincide with, or which exceed those specified will be deemed unauthorised unless contractually agreed. Damages resulting from such unau- thorised uses will not be the liability of the manufacturer. -
