- Place the washers on the attachments and the pro-
tection for the inspection flange (4)
- Place the rear protection plate by closing the inter-
locking flaps (L) without closing completely (leave
one tooth open)
- Apply the upper insulation (2) and the upper cover
(5) (in order to insert the cover, exert a light and ho-
mogeneous pressure)
- Close the interlocking flaps (L) completely, which
were previously left with an open tooth

IDRA DS N
storage cylinders in old
systems or systems requiring modernisation, always per-
form 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).
