Place of installation
BERETTA STOR C combination storage cylinders can be installed in any room where there is
no specific requirement for an electrical protection rating higher than IP X0D.
b
The room where the appliance is installed must, however, be dry to prevent the formation
of rust.
b
Specified minimum distances must be respected, and the space in which the combination
storage cylinder is to be installed must be easily accessible in order to permit easy instal-
lation and assembly and subsequent inspection, maintenance and repair. In particular,
access must permit the combination storage cylinder to be removed without disassembly
at the end of its useful life, and another unit to be installed in its place. Users are therefore
responsible for any costs incurred to demolish masonry or other structures preventing
or impeding free access to the space where the combination storage cylinder is to be
installed.

Installation in older systems
and systems requiring mod-
ernisation
When installing BERETTA STOR C combina-
tion storage cylinders in old systems or sys-
tems requiring modernisation, always perform
the following checks:
- Make sure that the system is fitted with
safety and control devices in accordance
with applicable legislation and standards.
- Make sure that the 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 sup-
ply/recirculation water so demands. (Refer
to the reference values listed in the table
alongside).
