Electrical connection
The system's internal electrical components have been wired at the factory. Connect the
system to the mains (230 V/AC, 50 - 60 Hz) using the attached power cable. Any work
performed on energised parts of the module must be carried out exclusively in accor-
dance with the requirements of the power supply utility and relevant current standards
and regulations. Correct earthing for the FWS-2-80 is provided at the mounting lug.
Protect the drinking water side of the freshwater module against excess pressure
using a safety valve rated to
≤
10 bar. A drinking water expansion vessel can also
be used as an alternative.
Connect the pipework as shown in the adjacent diagram. When using galvanised pipes
and fittings, observe the installation procedure for preventing electrochemical corrosion.
Tighten flat gasket connections only after the pipes have been sealed in. The pipework
to and from the cylinder, for example when mounting the FWS-2-80 on the wall, must
be sized no less than Cu 28.
Keep lines as short as possible.
CAUTION!
Avoid applying any torque or forces to
prefitted components and connection points of
the module.
