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 boiler and solar collectors
have been made correctly
− All the pipes in the water circuit have been insulated in
conformity to relevant standards
− 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 col-
lectors)
− Start up the boiler (if installed) as instructed in its own
manual.
− 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
− Make sure that all circuits have been bled.
− Make sure that the boiler and solar collectors connect-
ed to the system shut down correctly when their mains
power switches are turned OFF .
Provided the above checks have been completed satisfactorily,
restart the system and verify its performance.
