GreenTronic 7000T Leak Detection Kit Installation Instructions Part No. 7738007445 1 Leak Detection Kit Overview The leak protection kit is an optional accessory that can minimize the water damage of a leaking storage tank. When water is detected by the float sensor the automatic shutoff valve will prevent additional water from being added into the tank, limiting the leak potential to only the volume of water in the tank. The unit will show error code PH22 when water is detected and trigger an audible alarm. This kit only works with the Bosch GreenTronic 7000T hybrid electric water heater. 2 Leak Detection Kit Components The following parts are included with the Leak Detection Kit and are not sold individually: 3 Installation DANGER Hazardous voltage!
