Compatible with all B3.2 or B4.2 models, either free-standing or counter-top (240v and 110v). To app-enable a B3.2 or B4.2 an engineer or qualified technician will need this kit. New shipments of these models can be app-enabled for you prior to distribution. Using Bluetooth® technology, the app enables users to dispense water hands-free. This makes it ideal for use in high footfall locations such as offices and factories. It’s not only functional but gives customers peace of mind that their drinking water is as safe as it is refreshing. To operate the dispenser the user will also need to install the free Borg & Overström app on their smart device.
