The description of your selected version and order confirmation determine what is included. A picture or a similar package does not replace these details. Check the main unit, storage tank, controls, connections and accessories.
Optional accessories are additional items and are not automatically included. Whether a component is needed and compatible depends on the specific installation.
Send your product link and version to support@gema-net.de for a check against confirmed technical data. Do not modify safety-related components without qualified clarification.
