2 PRECAUTIONS
The operation of any appliance that uses electrical power
demands that a number of fundamental safety precautions
be respected. In particular:
a
Never attempt to install the system without using sui-
table personal protection equipment and without fol-
lowing all applicable occupational safety standards.
a
Do not touch the storage cylinder when barefoot or
wet if it has any electrical accessories connected to
it.
a
Never clean or service the storage cylinder without
first turning the mains power switch OFF to discon-
nect all electrical accessories (if fitted) from the mains
electricity supply.
a
Never pull, disconnect, or twist any electrical cables
coming from the appliance even if it is disconnected
from the mains electricity supply.
a
Do not expose the storage cylinder to the elements. It
is not designed for use outdoors.
a
If the pressure in the solar collector circuit drops, do
not top up with water alone, since this increases the
risk of damage from freezing.
a
Do not use connections or safety devices or fittings
(expansion vessels, pipes, insulation) that are not
specifically designed and tested for use in solar wa-
ter heating systems.
a
Do not allow children or infirm persons to operate the
system unsupervised.
a
Do not dispose of packaging material into the envi-
ronment, or leave it within the reach of children, since
it can become a potential hazard. Dispose of packa-
ging material in compliance with applicable legisla-
tion.

GENERAL
3 DESCRIPTION OF THE
APPLIANCE
B IDRA N DS solar storage cylinders are double coil
units designed for installation in domestic hot water pro-
duction systems heated by solar collectors. They come in
capacities 1500, 2000 and 2600.
The most important technical features of these solar stora-
ge cylinders are:
- The cylinder and coils are specially designed and
shaped for optimum performance in terms of stratifi-
cation, heat exchange and replenishment times
- vitrified cylinder lining, bacteriologically inert for ma-
ximum hygiene of the water, reduced lime scale de-
posits and easy cleaning
- CFC-free polyurethane insulation and an elegant ex-
ternal casing reduce heat loss
- Water fittings are available at different heights, per-
mitting different hot water generators to be used wi-
thout reducing the stratification effect
- a flange for easy cleaning and maintenance of the
anti-corrosion magnesium anode.
B IDRA N DS storage cylinders can be connected to a
special solar regulator and can be integrated in solar hea-
ting systems in which Bboilers or water heaters provi-
de supplementary heat.

b
B IDRA N DS storage cylinders are delivered wi-
thout a boiler heating pump. A suitably rated pump
must be provided and installed separately. Flow rate
from the solar collector circuit depends on the type
and number of collectors installed. For further infor-
mation, consult the manual for the collectors.
b
The domestic hot water system MUST INCLUDE an
expansion vessel, safety valve, automatic vent valve
and storage cylinder drain cock.
b
Safety valves must be connected to a suitable col-
lection and drain system. The manufacturer declines
all responsibility for damage caused by water esca-
ping from safety valves.
b
The choice of system components and the method
of their installation are left up to the heating engineer
installing the system. Installers must use their exper-
tise to ensure proper installation and functioning in
conformity to all applicable legislation.
b
Circuits filled with anti-freeze must be fitted with water
disconnectors.
b
If the water supply is unsoftened, avoid setting the
maximum temperature of the storage cylinder above
60°C, since higher temperatures can lead to the for-
mation of more lime scale and consequently poorer
thermal exchange efficiency.
b
Make sure that the storage cylinder is full of water
before starting up the solar heating system.

9
GENERAL
b
If the storage cylinder is installed in systems that ope-
rate at pressures in excess of 4 bar, fit a pressure
reducer.
b
Take care when opening the solar heating circuit’s
vent valve. Risk of burns!
b
Make sure that the expansion vessel is able to wi-
thstand high temperatures and that its membrane is
resistant to the water-glycol mix.
b
Use a thermostatic mixer valve to limit the domestic
hot water outlet temperature.
b
If the pressure in the solar heating circuit drops, do
NOT top up with water but use the proper water-glycol
mix. Risk of freezing!
b
All piping, collectors, heat exchangers and other de-
vices in the circuit must be subjected to proper hy-
draulic seal testing.
8 LOCATION OF SENSORS
B IDRA N DS storage cylinders are equipped with de-
dicated sockets for the storage cylinder TEMPERATURE
GAUGE or TEMPERATURE SENSOR.
b
The installer is responsible for making all necessary
connections to the boiler and solar collectors. Installers
must use their expertise to ensure proper installation
and functioning in compliance with all applicable legi-
slation.
b
Joins between temperature sensor cables and con-
trol panel extension cables must be soldered and
protected by sheaths or other forms of electrical in-
sulation.

We recommend that you install isolating valves in the outlet and return lines.
b
Check the efficiency of the seals when filling/refilling the storage cylinder.
