When installing
R
7200/1 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).

It is essential to perform the following checks before starting up
or testing the functioning of the storage cylinder. In particular,
check that:
− The supply cocks in the domestic water circuit are all open
− The water connections to the solar storage cylinder's
valve group have been made correctly
− All the pipes in the water circuit have been insulated in
conformity to relevant standards
− The electrical connections of any accessories have been
made correctly, using the hoses provided to route the
cables. See page 9 as well as the manuals for all installed
accessories
− The solar collector circuit has been correctly flushed out
and filled with water-glycol mix, and all air has been bled
out of the circuit (see the manual for the solar collectors)
− Put the solar collectors into service. See the manuals for
the solar collectors and associated accessories.
once the system has been started up, perform the following
checks.
− Make sure that all pumps are free and rotate in the right
direction
− Check that the flow rate in the solar collector circuit is
equivalent to 30 l/h for each m
− check that the solar collector circuit has been properly
bled
− Turn the main power switch oFF and make sure that the
solar water heating system shuts down completely.
Provided the above checks have been completed satisfactorily,
restart the system and verify its performance.
