2 INSTALLER
2 .1 Receiving the product
The
B
IDRA HP
boilers are supplied in a single case,
protected by a nylon bag and placed on a wooden pallet
(fig. 4).
The following material is placed inside a plastic bag inside
the packing:
- Instruction booklet
- Hydraulic test certificate
b
The instruction manual is an integral part of the boiler
and it should be read and then kept with care.
2 .2 Handling
The boiler must be handled with equipment that is suitable
for the weight of the unit (fig. 5).
- Unscrew the bolt (a) from the bottom of the storage
cylinder to release it from the pallet
- To lift the storage cylinder, remove the top cover and
screw an eyebolt suitable for the weight of the stora-
ge cylinder and welded to a fitting (Ø 1”1/4 not sup-
plied) into the hot water outlet (b)
- Lift the storage cylinder using a crane or hoist of sui-
table capacity for the weight involved.
b
Use adequate accident prevention protection.
a
It is forbidden to abandon and leave the packaging
material within the reach of children as it can be a
source of risk.
2 .3 Installation on system that are
old or need restoration
When
B IDRA HP
boilers are installed on systems that
are old or need modernising, check that:
- The installation is fitted with safety and control devi-
ces in compliance with specific regulations.
- The system is flushed, clean of sludge, incrustations,
bled of air, and the hydraulic seals are in order
- There is a treatment system for particular feeding/
recirculation water (the values indicated in the table
can be taken as reference values).

3 TECHNICAL ASSISTANCE SERVICE
3 .1 Setting up
Before performing the functional test and the starting up of
the boiler it is essential to check the following:
- That the non-sanitary hot water circuit water supply
taps are open (fig. 6)
- Eventual water connections to the associated heat
pump and the hydraulic system of the solar system
have been made correctly
- The washing procedure has been completed correct-
ly and an eventual solar circuit ha been filled with a
mix of glycol-water, and the air has been bled from
the system.
3 .2 Maintenance
The routine maintenance, essential for the safety, the per-
formance and the duration of the boiler, reduces consu-
mption and keeps the product reliable over the years. The
maintenance must be carried out by the
B
Technical
Service Centre or by professionally qualified personnel, at
least once each year.
Before performing any maintenance operations:
- Cut off the electrical power supply to the componen-
ts of the hydraulic circuit and the associated genera-
tor, setting the master switch on the system and that
on the boiler control panel to “OFF”
- Close the interception devices on the non-sanitary
hot water system
- Empty the boiler, or rather, the secondary circuit of
the boiler if the primary circuit is present.
3 .3 Cleaning the boiler and
dismounting the internal
components
3 .3 .1 Outside
The boiler casing must be cleaned using cloths and soap
and water.
If there are persistent stains, dampen the cloth with a mix
of 50% water and denatured alcohol or with specific pro-
ducts.
On completion, dry the boiler.
a
Do not use abrasive products, benzene or trichloro-
ethylene.
3 .3 .2 Inside
- With a wrench, loosen the fixing nuts on the flange
and extract the counter-flange together with its gasket
- Clean the inside surfaces, and remove any residue
through the opening. When the cleaning is comple-
ted, remount all the components by operating in the
reverse order to that described above.
b
Tighten the flange fixing bolts with a “crosswise” ope-
ration, to apply a uniform pressure on the gasket.
- Fill the boiler circuit and check that the gaskets do
not leak
- Carry out a performance check.
