• Running hot water with temperature above 50 °C may cause
serious burn marks.
• Improper installation may cause injuries to people or ani-
mals, or cause damages in objects. The manufacturer as-
sumes no liability for these.
• Before activating the heating, the tank must be fi lled with wa-
ter.
• 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 plas-
tic pipe rated up to min. 100 °C , or fl exible 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 pres-
sures exceeding 0.6 MPa. If the pressure of the pipeline ex-
ceeds 0.6 MPa, even on a temporary basis, a pressure reduc-
tion valve has to be mounted in front of the hot water tank.
• It is forbidden to insert water pipeline fi tting 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 non-visible manner.
• The pressure reduction valve and the safety valve must be in-
stalled 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 of overvoltage category III (with 3mm gap between
open contacts).
