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 suit-
able personal protection equipment and without fol-
lowing all applicable occupational safety standards.
a
Do not touch the product when barefoot or wet if it
has any electrical accessories installed in it.
a
Never clean or service the storage cylinder without
rst turning the mains power switch OFF to discon-
nect all electrical accessories (if tted) 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
Do not allow children or inrm 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 packag-
ing material in compliance with applicable legislation.
3 DESCRIPTION OF THE
APPLIANCE
The B IDRA MS boiler produces domestic hot water for
storage purposes.
Their most important technical features are:
- the storage cylinder and coil are specially designed
and shaped for optimum performance in terms of
stratication, heat exchange and replenishment times
- internal glazing, bacteriologically inert, to ensure the
maximum hygiene of treated water, reduce limescale
deposits and make cleaning operations easier
- CFC-free polyurethane insulation and an elegant ex-
ternal casing reduce heat loss
- a ange is provided for easy cleaning and mainte-
nance of the anti-corrosion magnesium anode.

9 INSTALLATION IN OLDER
SYSTEMS AND SYSTEMS
REQUIRING MODERNISATION
When installing B IDRA MS storage cylinders in old sys-
tems or systems requiring modernisation, always perform
the following checks.
- Make sure that the system is tted with safety and
control devices in accordance with applicable legis-
lation and standards
- Make sure that the central heating circuit has been
ushed 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.)

12 RECYCLING AND DISPOSAL
The device is primarily composed of:
Material Component
steel structural work
PU (polyurethane) insulation
PE (polyethylene) water connection washers
ABS (acrylonitrile-butadiene-styrene) lining and covers
At the end of the device's useful life, these components must be separated and disposed of according to current regu-
lations in the country of installation.
END USER INSTRUCTIONS
Refer to the GENERAL SAFETY INFORMATION and PRECAUTIONS section for safety-related information.
13 START-UP
The heater commissioning must be performed by Techni-
cal Assistance Centre personnel.
Under certain circumstances, such as after long periods of
disuse, the user may need to re-start it without involving the
Technical Assistance Centre. Before doing so, perform the
following checks and operations.
- Check that the supply cocks in the domestic water
circuit are all open
- Switch the electricity supply ON at the mains power
switch and at control panel switch (if tted).
14 TEMPORARY SHUTDOWN
To reduce to the environmental impact and save energy,
in case of brief absences, week-ends, short trips, etc., and
with external temperatures above 0°C, set the heater tem-
perature control, where available, to the minimum value.
b
If the temperature to which the heater is exposed can
fall below 0°C (frost hazard), perform the operations
described in paragraph "Preparing for extended pe-
riods of disuse".
15 PREPARING FOR EXTENDED
PERIODS OF DISUSE
If the storage cylinder is not going to be used for an ex-
tended period of time, ask the manufacturer’s Technical
Assistance Centre to make the system safe.
16 EXTERNAL MAINTENANCE
Clean the outside of the storage cylinder with a soft cloth
damped in soapy water.
a
Do not use abrasive products, petrol or triethylene.
