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 electrical connections have been made correctly
(using the hoses provided to route the cables on models
200 to 550.) See page 9 as well as the manuals for all
installed accessories
− Shut down the water heating system connected to the
storage cylinder as instructed in its own manual.
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.
− Turn the main power switch OFF and make sure that the
water heating system shuts down completely.
Provided the above checks have been completed satisfactorily,
restart the system and verify its performance.
