Technical Assistance Service - Beretta IDRA HP 300 Installation Manual

2 INSTALLER
2 .1 Receiving the product
The boilers are supplied in a single case,
B IDRA HP
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 boilers are installed on systems that
IDRA HP
B
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 .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
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.
