HYDRAULIC CONNECTION.
Perform the hydraulic connection of the Trio Pack Hybrid, re-
ferring to the relative instruction sheet and to the connection
template on the Solar Container.
ATTENTION.
Before making the connections, care-
fully clean the heating system (pipes,
radiators, etc.) with special pickling or de-scal-
ing products to remove any deposits that could
compromise correct operation of the boiler,
hydraulic unit and storage tank unit.
N.B.: remove all the protection caps on
the flow and return pipes of the hydron-
ic unit, before making the hydraulic
connections.
The connections can be made directly using
the female couplings on the hydronic unit or
by inserting system cut-off cocks (optional).
These cocks are particularly useful for mainte-
nance as they allow you to drain the hydronic
unit separately without having to empty the
entire system.
ATTENTION.
To preserve the duration of appliance
efficiency features, we recommend
installation of a suitable device for water
treatment in presence of water whose charac-
teristics can lead to the deposit of lime scale.
ATTENTION.
To preserve the correct operation of the
manifold inside the hydraulic circuit, it
is necessary to install an inspectable Y-filter,
present in the accessory boxes, on the return
of the zones.

SAFETY VALVE DRAIN.
8 bar domestic hot water safety valve.
Screw the fitting (d10) onto the safety valve. Screw the funnel
(d11) onto the fitting (d10) and convey the outlet to the drains.
Hydronic group 3 bar safety valve.
Tighten the rubber fitting (d12) to the safety valve of the hydronic
group. Connect the silicone pipe (d13) to the fitting (d11) and,
after having cut it to size, insert it into the funnel (d11) as shown
in Fig. 14.
The appliance safety valves outlet must be connected to
a draining funnel.
Otherwise, the appliance's manufacturer declines any
responsibility in case of flooding if the drain valves cut.
A treatment of the heating and water system water is required,
in compliance with the technical standards in force, in order to
protect the system and the appliance from deposits (e.g. scale),
slurry or other hazardous deposits.
Water connections must be made in a rational way using the
couplings on the indoor unit template.
