intended for the appliance are used.
7.2 Instructions, standards and regulations
Observe all applicable national and regional regula -
tions and instructions.
7.2.1 Important information
– Pressurised connection:
◦ Never exceed the operating pressure of 0.6 MPa.
◦ Route the blow-off line of the safety valve with a fall
and leave open to atmosphere.
◦ The safety valve requires regular maintenance and
activation.
– Unpressurised connection:
◦ Never exceed the operating pressure of 0 MPa.
◦ Do not install a safety valve.
8. Appliance description
The appliance is designed for undersink installation for
the heating of cold water.
The internal steel cylinder has a special enamel coating
and is equipped with a protective anode. The anode pro-
tects the internal cylinder against corrosion.
– Pressurised connection:
The appliance is designed to supply one or several draw-
off points. It must only be operated with pressure tested
taps. In addition, a type-tested diaphragm safety valve
with non-return valve must be installed.
– Unpressurised connection:
The appliance is designed to supply one draw-off point. It
must only be operated with an open (unpressurised) tap.

» Install a pressure reducer upstream of the diaphragm
safety valve in the water line if the static pressure
exceeds 0.48 MPa.
9.2 Installation location
The appliance is exclusively designed for installation on
a solid wall. Ensure the wall offers adequate load bearing
capacity.
Always install the appliance vertically, with the water con-
