Safety instructions The installation and commissioning as well as the connection of electrical components require technical knowledge commensurate with a recognised vocational qualification as a fitter for plumbing, heating and air conditioning technology, or a profession requiring a comparable level of knowledge [specialist]. The following must be observed during installation and commissioning: - relevant local and national regulations - accident prevention regulations of the professional association - instructions and safety instructions mentioned in these instructions.
WARNING Malfunction! - The product must be integrated in the potential equalisation of the electric installation. This can be guaranteed by establishing a potential equalisation connection to the main potential connection according to regulations or by the connected pipe system.
CAUTION Risk of burns! Valves, fittings and pump may heat up to more than 95 °C during operation. The insulating shell must remain closed during operation.
NOTICE Material damage due to mineral oils! Mineral oil products cause lasting damage to seals made of EPDM, whereby the sealant properties get lost. We do not assume liability nor provide warranty for damage to property resulting from sealants damaged in this way. - It is imperative to avoid that the EPDM sealing elements of the unit get in contact with substances containing mineral oils. - Use a lubricant based on silicone or polyalkylene and free from mineral oils, such as Unisilikon L250L and Syntheso Glep 1 of the Klüber company or a silicone spray.
