are excluded from the guarantee and product liability.
All water heaters provided with a rating plate bearing the designation 'nominal pressure 10 bar' (atmospheric excess pres-
sure kp/cm²) are pressure-proof storage tanks and can be connected on a pressure-proof basis using a line pressure up
to 5.5 bar.
A pressure reducing valve must be installed in the cold water supply line should the line pressure be higher!
A safety valve combination consists of a shutoff, test, swing check, drain and safety valve with an expansion water drip and
is installed between the cold water supply line and the cold water supply of the storage tank in the order as drawn.
Principally, the following must be observed:
drain of the safety valve must be open and observable and the outlet pipe from the drop collector (expansion water funnel)
must lead into the sewer, so that neither frost nor clogging by dirt and similar can cause any malfunction.
No shutoff valve or other throttling must be installed between the safety valve and the cold water supply of the storage tank.
The safety valve must be set to a response pressure that is lower than the nominal pressure (10 bar) of the storage tank.
safety valves (domestic water and heating circuits) must open out into an appropriate drainage object in order to avoid any
regulations and laws must also be observed.
