• Running hot water with temperature above 50 °C may cause
serious burn marks.
• Improper installation may cause injuries to people or animals,
or cause damages in objects. The manufacturer assumes no
liabilityfor these.
• Before activating the heating, the tank must be filled with wa-
ter .
• It's forbidden to connect the appliance using a hose. For cold
and hot water connections, steel or red copper pipe rated for
0.6 Mpa nominal pipeline pressure, heat resistant plastic pipe
rated up to in. 80 °C, or flexible connection may equally be
used. When connecting to a copper pipeline, the use of insu-
lating spacers is compulsory.
• It is forbidden and dangerous to expose the tank to pressures
exceeding 0.6 MPa. If the pressure of the pipeline exceeds 0.6
MPa, even on a temporary basis, a pressure reduction valve
has to be mounted in front of the hot water tank.
• It is forbidden to insert water pipeline fitting between the
safety valve and the appliance. The valve outlet must be di-
rected downward, and water may leak from the drainage pipe
of the pressure release device. This pipe must be left open
towards the air space. The drainage pipe must be directed
downwards (from the appliance) into a frost free room, and
free drainage must be ensured towards the air space. It is for-
bidden to divert water leakage in non­visible manner.
• The pressure reduction valve and the safety valve also must
be installed and operated in a frost free environment.
• It is forbidden to operate the hot water container without any
protective earthing.
• The connection of the container to the electrical system must
be of a permanent design. Wall sockets may not be used.
• Cable connection must be implemented from the water heat-
er to the isolation switch, which must be incorporated in the
fixed wire network. The overcurrent protection of the isolation
switch must be ensured using a miniature circuit breaker.
