Connection to the central heating system
Cylinder must be fitted to the central heating system
by pipe unions 3/4″. A cut-off valves must be installed
before the pipe unions. A flow rate of heating water must
be high enough to maximise cylinder’s efficiency (see
technical data table). It concerns the forced circulation
installation (with a central heating water pump).
Connection to the water system
Connection to the water system must be performed according to binding norms of
hydraulic installation. The cylinder is a pressure appliance designed for connection to
the water supply system where the water pressure doesn’t exceed 0,6 MPa. If the water
pressure exceeds 0,6 MPa, the pressure reducing valve before cylinder must be fitted.
Please follow the water connection instructions below:
-
install the T-connection with 6 bar safety valve (e.g. ZB-4) to the fitting of cold
water inlet [ZW]. It’s forbidden to install a cut-off valve (or any flow reducer)
between tank and the safety valve and on its outlet. The safety valve must be
installed in such a place as to quickly let you notice the outgoing water,
-
install the cylinder equipped with the safety valve to the water system,
-
install the cut-off valve on cold water supply pipe.
Hot water outlet should be led to the connection 3/4″ in the upper part of the cylinder.
Every cylinder is equipped with connection 3/4″ intended for its installation to the
DHW circulation.
