 The realization of the inflation module is kept as simple as possible and is presented in Figure 4a). The module consists of a round tube welded to a steel plate. The diameter of the tube is approximately 1cm smaller than the bottle opening to ensure quick and reliable mounting of the bottle. The steel plate is welded to or screwed onto the surface on the workbench below the module.

 Figure 5 illustrates the components of the water module. Initially, the placement of the pump and pressure tank must be determined. Following this, a rubber hose is cut to the required length to link all components. Typically, these components are equipped with threaded ends, allowing for the attachment of an threaded hose nipple. The hose is then attached to the components and fastened securely with hose clamps. Adding the clamps is crucial since the system operates under pressure, necessitating a tight and secure connection to prevent leaks and maintain system integrity. The schematic in Figure 5 also displays the order in which the components are installed. In the following a quick functional summary of the different parts is given:
