GENERAL INFORMATION
9
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.
2 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,
or leave it within the reach of children, since it can become
a potential hazard. Dispose of packaging material in com-
pliance with applicable legislation.
3 DESCRIPTION OF THE APPLIANCE
R
7200/3F HV PLUS solar tanks can be integrated into solar
systems to produce domestic hot water. They can also be paired
with heat pumps or boilers and heating units.
The most important technical features of these solar storage cyl-
inders are:
− special tank design and shape for optimum performance
in terms of stratification, heat exchange and replenish-
ment time
− Water fittings are available at different heights, permit-
ting different hot water generators to be used without
reducing the stratification effect
− insulation made of expanded polyurethane free from CFC
(chlorofluorocarbons)
− the use of three flanges, which means additional ex-
changers can be added
4 IDENTIFICATION
The
R
7200/3F HV PLUS solar heaters can be identified by:
Data plate
This lists the technical specifications and performance of the
product.
Serial number plate
This specifies the serial number and model.
9
If these plates or any other means of clearly identifying
the product are defaced, removed or lost, proper instal-
lation and servicing may be rendered difficult.
9
On models 2000 and 3000 the technical data plate and
serial number plate must be applied (by the installer) af-
ter the insulation has been fitted.
