It is essential to perform the following checks before starting
up or testing the functioning of the combination 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 collectors)
− 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.

The domestic hot water tank must be filled and pressurised
before the buffer tank is filled.
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 connected
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.
15 TEMPORARY SHUTDOWN
If you are going away for a short period of time like a weekend
or a short holiday, etc., and outdoor temperatures are going to
remain above ZERO, proceed as follows.
− Adjust the combination storage cylinder's thermostat to
its minimum setting.

If outdoor temperature may drop below ZERO (risk of
freezing) perform the operations described in the "Preparing
for extended periods of disuse" section.
16 PREPARINg FOR EXTENDED PERIODS OF DISUSE
If the combination storage cylinder is not going to be used for an
extended period of time, prepare it for shut-down as follows:
− Switch the electricity supply to the storage cylinder and to
any associated boiler OFF at the main switch and at the
control panel (if present)
− Close the shut-off cocks for the domestic hot water circuit.
9
Drain the central heating circuit and domestic hot water
circuit if there is any risk of freezing.
17 MAINTENANCE
Scheduled maintenance is essential for the safety, efficiency and
long working life of your combination storage cylinder. Proper
maintenance also reduces energy consumption and ensures
reliability over time. Have your combination storage cylinder
serviced either by the manufacturer's Technical Assistance
Service or by a qualified heating engineer at least once a year.
