Plug the HydroGize into a power source using the USB connector. Fully charge the battery. Unplug unit and add drinking water to the bottle then set the hydrogen generator to the desired timer setting. Do not shake while the generator runs. Instead, let it sit during hydrogen generation. Be sure to drink shortly after the hydrogenation cycle has finished. When using Vitality™ essential oils with HydroGize, be sure to thoroughly clean the device immediately following use to properly maintain the unit. Please note that adding oils may decrease hydrogen production. For ease of maintenance, move oil-enriched hydrogen water to a separate container if not consumed immediately.
