Application
The safety group is required to ensure the operation of pressure-resistant, closed wall-mounted storage tanks. It prevents exceeding the permissible operating pressure in the hot water storage tank as well as the return of heated drinking water into the piping system. Expansion water is discharged into the drainage line.

Equipment
The delivery scope of the safety group includes: safety valve, shut-off valve, backflow preventer, funnel siphon, rosette, and chrome-plated connection accessories.

Installation
The safety group is installed according to specifications before the hot water storage tank in the cold water supply line. It facilitates maintenance work by allowing the system to be vented via a rotary handle on the safety valve. Additionally, the cold water supply line can be closed for subsequent installations (e.g., hot water storage tank) using a shut-off valve. The individual components are interchangeable.

Safety
The safety group consists of a highly polished, chrome-plated brass housing, is low-lead manufactured, and DVGW certified. The safety valve is component tested. The connection pipes are made of chrome-plated copper. All plastic parts comply with the KTW recommendation.
