• 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 a closing valve or ball valve between
the safety valve and the appliance. The valve outlet must be
directed downward, as 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. It is forbidden to use of a mains
socket!
• Mains supply must be ensured for the tank via a two-pole
switch complying with the requirements of overvoltage
