• 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 liability for these .
• Before activating the heating, the tank must be filled with
water .
• It is 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 min. 100 °C or flexible connection
may equally be used. When connecting to a copper pipeline,
the use of insulating 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
directed 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 forbidden to divert water
leakage in non-visible manner .
• The pressure reduction valve and the safety valve 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.
• The current of the electric system has to be connected to the
container through a two-pole switch (disconnecting all poles)
ensuring full disconnection in an environment of overvoltage
category III. (At least 3 mm separation distance between
open poles.)
