for rinsing the Hydra Jet system with fresh water The Clean-Jet rinsing line, which is ordered separately, is solely used to rinse the Hydra Jet system with fresh water after a relaxing bath. This means practically all soap and foam residues can be readily removed from the hose lines along with particles of skin. Operation is only possible with a separate cold water connection with permanent pressure. Note: A corresponding pipe interrupter should be provided on site. Get advice from a fitter if necessary.
