Installation and Assembly
To ensure a satisfactory operation of the safety valves they must be assembled
in such a way that the safety valve is not exposed to any impermissible static,
dynamic or thermal loads.
Supply:
The safety valves must be installed vertically in line with the direction of the arrow
using a max. 1 meter long and straight connecting pipe of the same size as the
safety valve inlet cross section. The installation of dirt traps or restrictions in the
supply pipe to the safety valve is not permitted. Horizontal connecting pipes are to
be avoided to prevent deposits.
Blowing off pipe:
The blowing off pipe must be of a design that corresponds at least to the size of the
safety valve outlet cross section, it is to have no more than 2 bends and measure
max. 2 meters in length. If more bends or a longer length are required, the entire
blowing off pipe must be designed one diameter size larger. The blowing off pipe
must always be routed sloping downward and designed in such a way that it cannot
freeze and no water can accumulate in it. The opening must be arranged in such a
way to ensure that steam flows out and discharging heating water can be observed
and led off hazard free.
Series 651 mHNK/ mHIK/ HNs:
The safety valves are to be arranged in the boiler room at an easily accessible place
at the highest point of the heat generator or in the immediate vicinity thereof, on
the supply pipe.
Series 651 mSK:
The diaphragm safety valves must be installed open to the collectors in the cooler
area of the solar heating system, at an easily accessible position.
