PUTTING INTO SERVICE
It is essential to perform the following checks before starting up
or testing the functioning of the combination cylinder. In par-
ticular, 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 combination cylinder’s auxiliary heating
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.

Solar heating circuit
Once the system has been started up, perform the following
checks.
− 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
− Check that the pressure of the system when cold is ap-
proximately 3 bar
− Check that the safety valve operates at 6 bar
− All the pipes in the water circuit have been insulated in
conformity to relevant standards.
