made of durable elastic EPP, 100 % insulated valves and fittings - excellent ventilation and cooling of the pumps, minimal heat losses
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 Danger of scalding due to the escape of hot fluids! With pressure relief valves, there is a risk of scalding due to the escape of vapour or hot fluid. During installation, check the local conditions and check whether a discharge line must be connected to the safety group. - Observe the instructions regarding the pressure relief valve. - The pressures for the expansion tank calculated by the plant designer and the operating pressure of the installation must be set. WARNING Personal injury due to contaminated domestic water! Heating water contains harmful substances that must not be washed into the domestic hot water circuit. If the station has been used to charge a buffer tank, there is still heating water in the valves and fittings and in the pump of the secondary circuit, even after draining. The heating water cannot be completely removed. -The station must not be connected to a domestic hot water circuit any more.
CAUTION Personal injury and material damage due to overpressure! Closing both ball valves in the primary circuit will separate the safety group from the heat exchanger. A rise in temperature in the storage tank may result in high pressures, which may lead to personal injury and material damage! - Only close the ball valves for service and maintenance. - When closing the ball valves in case of servicing, also put the pumps out of operation and close the ball valves / piston valves of the secondary circuit. CAUTION Risk of burns! Valves, fittings and pump may heat up to more than 100 °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.
