15 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:
− All the connections and pipes are watertight and the
system has been filled and bled correctly
− Any water connections to a boiler or solar collectors have
been made correctly
− Any solar heating circuit has been correctly flushed out
and filled with water-glycol mix, and all air has been
bled out of the circuit
− The electrical connections of all accessories have been
made correctly
− 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.

16 MAINTENANCE

Scheduled maintenance is essential for the safety, efficiency and
long working life of your buffer tank. Proper maintenance also
reduces energy consumption and ensures reliability over time.
Have your buffer tank serviced either by the manufacturer's
Technical Assistance Service or by a qualified heating engineer
at least once a year.
Perform the following operations before beginning any
maintenance:
− Switch the electricity supply to all the devices in the buffer
tank's water circuit and to any associated boiler OFF at
the main switch and at the control panel (if present)
− Close the water shut-off cocks
− Drain the buffer tank.

damped in soapy water. To remove stubborn marks, use a cloth

suitable cleaning product. Dry the buffer tank after cleaning it.
