13 INSTALLATION IN OLDER SYSTEMS AND SYSTEMS
REQUIRING MODERNISATION
When installing R 7200 V Plus storage cylinders in old systems
or systems requiring modernisation, always perform the
following checks.
− Make sure that the system is fitted with safety and
control devices in accordance with applicable legislation
and standards
− Make sure that the central heating circuit has been
flushed out to remove all sludge and lime scale, and has
been vented and seal tested
− Make sure that a suitable water treatment system is
installed if the quality of the supply/recirculation water
so demands. (Refer to the reference values listed in the
table alongside.)
