INSTALLATION IN OLDER SYSTEMS AND SYSTEMS
REQUIRING MODERNISATION
When installing
R
7000 ACI PLUS
buffer tanks in old systems or
systems requiring modernisation, always perform the following
checks.
− Make sure that the system is fitted with safety and con-
trol 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 in-
stalled if the quality of the supply/recirculation water so
demands (refer to the reference values listed in the table
alongside).
