The warranty period is two years for all parts. It is limited to the delivery of the repaired or replaced parts free customer without installation / removal, etc.. Serious damage caused by overload or over voltage (eg lightning) on electrical components or by exceeding the maximum operating pressure or freezing in heat exchangers or pump groups (eg due to insufficient antifreeze in the brine circuit) are not covered under warranty. Please remember: Brine circuits must (just like a car radiator) be filled with so much anti-freeze, that the brine does not freeze even in the coldest temporarily outside air temperature.
