B IDRA BV storage cylinders can be installed in any
room where there is no specific requirement for an electri-
cal protection rating higher than IP X0D.
≥ 0,6 m
≥ 0,4 m
≥ 0,3 m ≥ 0,4 m
≥ 0,8 m
b
Respect the minimum specified installation distances to
ensure correct installation and access for maintenance.
Adjust the feet to ensure that the storage cylinder is per-
fectly level.

5 INSTALLATION IN OLDER
SYSTEMS AND SYSTEMS
REQUIRING MODERNISATION
When installing B IDRA BV storage cylinders in old sys-
tems or systems requiring modernisation, always perform
the following checks.
- Make sure that the system is fitted with safety and
control devices in accordance with applicable legis-
lation and standards
- Make sure that the central heating circuit has been
flushed out to remove all sludge and lime scale, and
has been vented and seal tested
- Make sure that a suitable water treatment system is
installed if the quality of the supply/recirculation water
so demands. (Refer to the reference values listed in
the table alongside.)
REFERENCE VALUES
pH 6-8
Electrical conductivity less than 200 μS/cm (25°C)
Chlorine ions less than 50 ppm
Sulphuric acid ions less than 50 ppm
Total iron less than 0.3 ppm
Alkalinity M less than 50 ppm
Total hardness less than 35°F
Sulphur ions none
Ammonia ions none
Silicon ions less than 30 ppm
6 MAINTENANCE
Perform the following operations before beginning any
maintenance:
- Switch the electricity supply to the storage cylinder’s
valve group and to any associated boiler OFF at the
main switch and at the control panel
- Close the shut-off cocks for the domestic hot water
circuit
- Drain the storage cylinder’s DHW (secondary) water
circuit.
7 CLEANING AND REMOVING
INTERNAL COMPONENTS
EXTERNAL CLEANING
Clean the outside of the storage cylinder with a soft cloth
damped in soapy water.
a Do not use abrasive products, petrol or triethylene.
INTERNAL CLEANING
Removing and checking the magnesium anode
- Remove the cover (1) (removing the screws first from
models 800 and 1000), and remove the insulation (2).
Use a suitable wrench to unscrew the anode holder (3)
- Check the magnesium anode for wear and replace it
if necessary.

On completion of cleaning, follow the above steps in the
reverse order to refit all removed parts.
NOTE: Tighten the anode plug to a torque of 25-30 Nm.
8 RECYCLING AND DISPOSAL
At the end of its useful working life, do not abandon the
storage cylinder in the environment, but dispose of it
through the proper channels in accordance with applica-
ble legislation.
