If the product is not going to be used for an extended peri-
od of time, contact the manufacturer’s Technical Assistance
Service to have at least the following operations performed:
− Close the shut-off cocks for the domestic hot water circuit
− Shut down the boiler connected to the storage cylinder
as instructed in its own manual

must be kept safe and must ALWAYS accompany the product,
even if it is sold to another owner or transferred to another
user or to another installation. If you lose this manual, or-
der a replacement immediately. Keep the product purchase

Size the solar expansion tank so as to ensure complete ab-
sorption of the expansion of the fluid contained within the
system, with reference to the prevailing regulations on the
matter. In particular, consider fluid characteristics, consid-
erable fluctuation of service temperature and vapour that
might be generated during solar collector stagnation stage.
Proper size of expansion tank ensures setting off of all vol-
ume changes of the heat transfer fluid, avoiding excessive
pressure increase. Limited pressure changes avoid reach-
ing safety valve opening pressure and the consequent fluid
drainage.

IMPORTANT SAFETY PRECAUTIONS
The operation of any appliance that uses electrical power de-
mands that a number of fundamental safety precautions be re-
spected. In particular:
0
Never attempt to install the system without using suitable
personal protection equipment and without following all
applicable occupational safety standards.
0
Do not touch the product when barefoot or wet if it has any
electrical accessories installed in it.
0
Never clean or service the storage cylinder without first
turning the mains power switch OFF to disconnect all elec-
trical accessories (if fitted) from the mains electricity supply.
0
Never pull, disconnect, or twist any electrical cables coming
from the appliance even if it is disconnected from the mains
electricity supply.
0
Do not expose the storage cylinder to the elements. It is not
designed for use outdoors.
0
If solar plant pressure decreases, it is forbidden to top up
with only water as there is a danger of freezing and over-
heating.
0
Do not use connections or safety devices or fittings (expan-
sion vessels, pipes, insulation) that are not specifically de-
signed and tested for use in solar water heating systems.
0
Do not allow children or infirm persons to operate the sys-
tem unsupervised.
0
Do not dispose of packaging material into the environment,
