Connection to the central
heating system
Cylinder must be fitted to the central
heating system by pipe unions 1’’ or
¾’’ (SW100 / SW120 / SW140). A
cut-off valves must be installed before
the pipe unions.
A flow rate of heating water must be
high enough to maximise cylinder
efficiency (see technical data table).
It concerns the forced circulation in-
stallation (with a central heating water
pump).SW cylinder is equipped with
one coil. SB cylinder is equipped with
two coils for connection to e.g. boiler
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) and the drain
valve to the inlet fitting of cold water [1]. It’s forbidden to install a cut-off valve
(or any flow reducer) between tank and the safety valve and on it’s outlet.
The safety valve must be installed in that place to let you quickly see 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 pipe must be connected to the ¾’’ fitting, which is located in the up-
per part of the unit.
Each cylinder is equipped with ¾’’ fitting for domestic hot water circulation connection.

and solar collector system. SWZ and SBZ cylinders are equipped with additional
connectors for external heat exchanger.
