Closed circuit operation (pressure-resistant)
■ Install in the vicinity of the tap at which most water is
taken.
■ Rinse the water pipes thoroughly to remove impurities
and contaminants before connecting the taps.
■ A safety valve (1) is to be fitted with a water pressure up to
0.5 MPa (5 bar). A pressure reducing valve (5) must be fit-
ted and set accordingly if the pressure exceeds this value.
■ A stop valve may not be fitted between the safety valve
(1) and the cold water supply.
The safety valve (1) outlet must always be open.
Safety valve combination AK 030300 and safety valve combi-
nation with pressure reducing valve AK 040300 can be fitted
with commercially available thermostat premixers.
Note: According to the energy conservation regulations, the
temperature in pipes may not exceed 60 °C if the length of
the warm water pipes exceeds 5 m.
■ Fill the appliance with water first until the water flows
from the fitting.
