Size the solar expansion tank so as to ensure com-
plete absorption of the expansion of the uid con-
tained within the system, with reference to the
prevailing regulations on the matter. In particular,
consider uid characteristics, considerable uctua-
tion of service temperature and vapour that might
be generated during solar collector stagnation stage.
Proper size of expansion tank ensures setting off of
all volume changes of the heat transfer uid, avoid-
ing excessive pressure increase. Limited pressure
changes avoid reaching safety valve opening pres-
sure and the consequent uid drainage.
Please remember that the use of products using electric
power and water involves respect for a few basic safety
rules such as:
Never attempt to install the system without using
suitable personal protection equipment and without
following all applicable occupational safety stand-
ards.
Do not touch the product when barefoot or wet if it
has any electrical accessories installed in it.
Never clean or service the storage cylinder without
rst turning the mains power switch OFF to dis-
connect all electrical accessories (if tted) from the
mains electricity supply.
Never pull, disconnect, or twist any electrical cables
coming from the appliance even if it is disconnected
from the mains electricity supply.
Do not expose the storage cylinder to the elements.
It is not designed for use outdoors.
If solar plant pressure decreases, it is forbidden to
top up with only water as there is a danger of freez-
ing and overheating.
Do not use connections or safety devices or ttings
(expansion vessels, pipes, insulation) that are not
specically designed and tested for use in solar wa-
ter heating systems.
Do not allow children or inrm persons to operate
the system unsupervised.
Do not dispose of packaging material into the en-
vironment, or leave it within the reach of children,
since it can become a potential hazard. Dispose of
packaging material in compliance with applicable
legislation.
