Size the solar expansion tank so as to ensure com-
plete absorption of the expansion of the fluid con-
tained within the system, with reference to the
prevailing regulations on the matter. In particular,
consider fluid characteristics, considerable fluctua-
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 fluid, avoid-
ing excessive pressure increase. Limited pressure
changes avoid reaching safety valve opening pres-
sure and the consequent fluid drainage.

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
