When installing
B
IDRA MS
storage cylinders in old sy-
stems 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 flu-
shed 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.)

14 PUtting into service
It is essential to perform the following checks before star-
ting 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 val-
ve 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 fol-
lowing 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
2
of collector area
- 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 satisfac-
torily, restart the system and verify its performance.
