1 INSTALLATION TRIO V2
1.1 DESCRIPTION OF THE DEVICE.
e Trio V2 pack described below allows you to
install in a special recessed frame called “Solar
Container” (not included in the supply) a hy-
dronic unit designed to be coupled with dierent
energy sources (heat pump, boiler, solar, excluded
from this supply), able to meet the winter central
heating / C.H., summer cooling needs, as well as
the production of domestic hot water, possibly
with solar integration (via special optional kit).
1.2 INSTALLATION
RECOMMENDATIONS.
e Trio pack has been designed solely for wall
installation using the special “Solar Container”
(recessed frame).
e place of installation of the appliance and
relative Immergas accessories must have suitable
features (technical and structural), such as to al-
low for (always in safe, ecient and comfortable
conditions):
- installation (according to the provisions of
technical legislation and technical regulations);
- maintenance operations (including scheduled,
periodic, routine and special maintenance);
- removal (outdoors in the place for loading and
transporting the appliances and components)
as well as their eventual replacement with
appliances and/or equivalent components.
Only a professionally qualied heating/plumbing
technician is authorised to install the Trio V2.
Installation must be carried out according to
regulation standards, current legislation and
in compliance with local technical regulations
and the required technical procedures. Before
installing the pack, ensure that it is delivered
in perfect condition; if in doubt, contact the
supplier immediately. Packing materials (sta-
ples, nails, plastic bags, polystyrene foam, etc.)
constitute a hazard and must be kept out of the
reach of children. Keep all ammable objects
away from the appliance (paper, rags, plastic,
polystyrene, etc.). In the event of malfunctions,
faults or incorrect operation, turn the device o
immediately and contact an authorised company
(e.g. the Authorised Technical Assistance Centre,
which has specically trained sta and original
spare parts). Do not attempt to modify or repair
the appliance alone. Failure to comply with the
above implies personal responsibility and inval-
idates the warranty.
• Installation Standards: this pack must be in-
stalled inside an external wall using the special
“Solar Container” and securing it with the
support brackets supplied together with the
pack itself. It was not designed to be installed
on plinths or oors and without the special
recessed frame.
Attention: installation of the “Solar Container” in
the wall must ensure a stable and ecient support
of the Trio V2 pack. e “Trio V2” ensures appro-
priate support only if installed correctly (accord-
ing to the rules of good practice), following the
instructions on its instructions leaet. e “Solar
Container” for the Trio V2 pack is not a support-
ing structure and must not replace the removed
wall; it is therefore verify its position in the wall.
For safety reasons against any leaks it is necessary
to plaster the pack housing in the brick wall.
is pack is used to heat water to below boiling
temperature in atmospheric pressure. It must
be connected to a central heating system and
domestic hot water circuit suited to its perfor-
mance and capacity.
“Anti-legionella” heat treatment of the
Immergas storage tank (activated by the spe-
cic function present on the predisposed ther-
moregulation systems): during this stage, the
temperature of the water inside the storage tank
exceeds 60°C with a relative risk of burns. Keep
this domestic hot water treatment under control
(and inform the users) to prevent unforeseeable
damage to people, animals, things.
