IDRA DS
solar heaters are supplied in a single package
on a wooden pallet.
The insulation and the lining components of the models 750 and
1000 are supplied separately from the structural work and are to
be assembled upon receiving the product as described in the
paragraph "Assembly of the insulation and the lining (models
750 - 1000)". For these models the magnesium anode is sup-
plied in a cardboard box.
The following items are delivered in a plastic bag inside the
packaging:
- Instruction manual
- Bar code label
- Hydraulic test certificate
- Energy label (to be applied to device upon installation)
- No. 4 adjustable feet to be mounted during installation (for
models 750 - 1000 only).
b
The instruction manual is an integral part of the solar stor-
age cylinder. Once located, read it thoroughly and keep
it safe.
b
For handling operations, thoroughly follow the instructions
on device package label.
8 ASSEMBLY OF THE INSULATION AND
THE LINING (MODELS 750 - 1000)
The assembly of the insulation and lining components must be
performed at the site of installation to facilitate passage through
any doors and/or entries to the room.
Proceed as follows:
- Assemble the insulating covers (1) around the body of
the heater, making sure that the engagement points on
the edges are positioned correctly. The edges are not re-
quired to be closed completely
- Place the front protection plate (3) correctly on the attach-
ments
- Place the washers on the attachments and the protection
for the inspection flange (4)
- Place the rear protection plate by closing the interlocking
flaps (L) without closing completely (leave one tooth open)
- Apply the upper insulation (2) and the upper cover (5)
(use a spatula if the cover application on the protection
plate proves difficult)
- Close the interlocking flaps (L) completely, which were
previously left with an open tooth.
If disassembling is required, proceed in reverse order.

10 INSTALLATION IN OLDER SYSTEMS
AND SYSTEMS REQUIRING
MODERNISATION
When installing
B
IDRA DS
storage cylinders in old systems
or systems requiring modernisation, always perform the follow-
ing checks.
- Make sure that the system is fitted with safety and con-
trol devices in accordance with applicable legislation 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 in-
stalled if the quality of the supply/recirculation water so
demands (refer to the reference values listed in the table
alongside).
