Note
•
To enable draining of the cylinder unit an
isolating valve should be positioned on both
the inlet and outlet pipework. No valve
should be tted between the pressure relief
valve (item 37) and the cylinder unit (safety
matter).
•
Be sure to install a strainer, on the inlet
pipework to the cylinder unit.
•
Suitable drain pipework should be attached
to all relief valves in accordance with your
country’s regulations.
•
A backow prevention device must be
installed on the cold water supply pipework
(IEC 61770)
•
When using components made from
different metals or connecting pipes made
of different metals insulate the joints to
prevent any corrosive reaction taking place
which may damage the pipework.
