1 GENERAL SAFETY INFORMATION

Check that the product is complete, undamaged and

as ordered as soon as you receive it. Report any di-

screpancies or damage to the Bdealer who sold

it.

This product must be installed by a legally qualiﬁed

heating engineer. On completion of the installation,

the installer must issue the owner with a declaration

of conformity conﬁrming that the installation has been

completed to the highest standards in compliance

with the instructions provided by Bin this in-

struction manual, and that it conforms to all appli-

cable laws and standards.

This product must only be used for the purpose

for which it is designed and made, as speciﬁed by

B. Bdeclines all responsibility, contractual or

other, for damage to property or injury to persons or

animals caused by improper installation, adjustment,

maintenance or use.

The product must be serviced at least once a year.

Servicing must be arranged in advance with the

BTechnical Assistance Centre.

All servicing and repairs must be performed by a

qualiﬁed heating engineer.

If water leaks from the storage cylinder, turn off the

water supply and contact B’s Technical Assistan-

ce Centre or a qualiﬁed heating engineer immedia-

tely.

If the solar storage cylinder is not going to be used for

an extended period of time, contact the manufactu-

rer’s Technical Assistance Centre 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 cylin-

der as instructed in its own manual

- Switch the storage cylinder OFF at the control panel

(if ﬁtted) and at the mains power switch

- Drain the central heating circuit and domestic hot

water circuit if there is any risk of freezing.

This instruction manual is an integral part of the pro-

duct. It must be kept safe and must ALWAYS accom-

pany the product, even if it is sold to another owner or

transferred to another user or to another installation.

If you lose this manual, order a replacement imme-

diately.

2 PRECAUTIONS

The operation of any appliance that uses electrical power

demands that a number of fundamental safety precautions

be respected. In particular:

Never attempt to install the system without using sui-

table personal protection equipment and without fol-

lowing all applicable occupational safety standards.

Do not touch the storage cylinder when barefoot or

wet if it has any electrical accessories connected to

it.

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.

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 the pressure in the solar collector circuit drops, do

not top up with water alone, since this increases the

risk of damage from freezing.

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.

Do not allow children or inﬁrm persons to operate the

system unsupervised.

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.

3 DESCRIPTION OF THE

APPLIANCE

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.

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.

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.

The domestic hot water system MUST INCLUDE an

expansion vessel, safety valve, automatic vent valve

and storage cylinder drain cock.

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.

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.

Circuits ﬁlled with anti-freeze must be ﬁtted with water

disconnectors.

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.

Make sure that the storage cylinder is full of water

before starting up the solar heating system.

GENERAL

If the storage cylinder is installed in systems that ope-

rate at pressures in excess of 4 bar, ﬁt a pressure

reducer.

Take care when opening the solar heating circuit’s

vent valve. Risk of burns!

Make sure that the expansion vessel is able to wi-

thstand high temperatures and that its membrane is

resistant to the water-glycol mix.

Use a thermostatic mixer valve to limit the domestic

hot water outlet temperature.

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!

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

IDRA N DS

storage cylinders are equipped with de-

dicated sockets for the storage cylinder TEMPERATURE

GAUGE or TEMPERATURE SENSOR.

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.

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.

GENERAL

9 OVERALL DIMENSIONS AND WATER FITTINGS

storage cylinders can also be connected to previously installed hot water sources provided heat output

is suitable and care is taken to ensure correct water ﬂow directions.
