In order to ensure the faultless function
of the connection fitting, it may
only be installed in frost-protected
rooms. The discharge of the safety
valve must be open and observable
and the discharge line from the drip
catcher (expansion water funnel) must
be routed to the sewer so that neither
frost nor back-ups from dirt or the like
can cause a fault.
There may not be a shut-off valve or any
other type of flow restrictor installed
between the safety valve and the cold
water feed of the tank.
The safety valve must be set
to a triggering pressure which is below
the nominal pressure of the tank.
After the conclusive connection
of the tank, the cold water supply line
must be rinsed out.
After the water connection is made
and the bubble-free filling of the tank
takes place, the connected fitting must
be tested for function.
When lifting or turning (venting)
the safety valve test knob, the water
must be able to flow out properly
without being hindered by the expansion
tank drain funnel.
In order to check the return flow valve
the shut-off valve is closed and no water
may flow out of the open testing valve.
The testing of the safety valve must take
place in accordance with DIN 1988-8.
