CONSTRUCTION
METHOD OF OPERATION
Safety groups of this type combine check valve, shut-off
valve, test point and diaphragm type safety valves in one
appliance. Flow first passes through the check valve and this
flow holds the valve disc in the open position against the
force of a spring.
The downstream safety valve is a direct operating safety
valve. That is, the opening force operates against the force of
a spring. The shut-off valve enable the check valve to be
checked and serviced.
TRANSPORTATION AND STORAGE

INSTALLATION GUIDELINES
Setup requirements
• Safety group must be fitted in the cold water supply to
the hot water storage unit
• Horizontal and vertical installation position possible
• The installation must be carried out so that:
– There are no shut-off valves or fittings, narrowing of
the pipework or strainers between the water heater
and the safety valve
– Good access is provided for service and
maintenance
– The safety valve is fitted above the top of the water
heater to avoid the need for draining down when
exchanging the safety valve insert
• If there is no drainage facility in the room where the
heater is installed, then the safety valve may be fitted in
an adjacent area. DIN 1988-200 is to be observed
• Requires regular maintenance in accordance with
EN 806-5
