SYSTEMS AND SYSTEMS
REQUIRING MODERNISATION
When installing
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).

14 PUTTING INTO SERVICE
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 have been made correctly
(use the flexible cable conduits provided to route the
cables. See pages 9 - 10 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.
