IMPORTANT!
Incorrect positioning or installation of the unit may
amplify noise levels and vibrations generated
during operation.
The following accessories are available to reduce noise and vibration:
KSA - Anti-vibration mountings.
When installing the unit, bear the following in mind:
non-soundproofed reflecting walls near the unit may increase the
total sound pressure level reading near the appliance by as much as 3
dB(A) for every surface;
install suitable anti-vibration mountings under the unit to avoid
transmitting vibrations to the building structure;
make all water connections using elastic joints. Pipes must be firmly
supported by solid structures.
If the pipes are routed through walls or panels, insulate with elastic
sleeves. If, after installation and start-up of the unit, structural vibrations
are observed in the building which provoke such strong resonance that
noise is generated in other parts of the building, consult a qualified
acoustic technician for a complete analysis of the problem.

WATER CONNECTIONS
II.6.1
CONNECTION TO THE SYSTEM
IMPORTANT!
The layout of the water system and connection of
the system to the unit must be carried out in
conformity with local and national rules in force.
II.6.3
MINIMUM CONTENT OF HYDRAULIC CIRCUIT
All units are equipped with an expansion vessel that limits the maximum water content of the system. If the water content exceeds the indicated values,
another expansion vessel must be added.

We recommend installing isolating valves that
isolate the unit from the rest of the system. Mesh
filters with a square section (longest side = 0.8 mm),
of a suitable size and pressure drop for the system,
must be installed. Clean the filter from time to time.
○ The unit is equipped with threaded male water connections and a
manual air bleed valve positioned inside the shell.
○ It is advisable to install intercept valves that isolate the unit from the
rest of the system. It is also advisable to install elastic connection joints.
○ It is essential to fit a metal mesh filter (square mesh of no greater
than 0.8 mm), of a suitable size and pressure drop for the system, on
the unit return piping.
○ The water flow through the heat-exchanger should not fall below a
value corresponding to a temperature differential of 8°C.
○ During long periods of inactivity, it is advisable to drain the water
from the system.
○ It is possible to avoid draining the water by adding ethylene glycol to
the water circuit (see Protecting the unit from frost).
Pump installation
○ The units are equipped with a circulating pump, expansion tank and
safety valve.
Tank & Pump installation
○ The units are equipped with an inertial water buffer tank, circulating
pump, expansion tank with membrane, drain cock and safety valve.
Once the connections to the unit are made, check that none of the
pipes leak, and bleed the air from the system. The water flow through
the heat-exchanger should not fall below a value corresponding to a
temperature differential of 8°C.
II.6.2
MINIMUM CONTENT OF HYDRAULIC CIRCUIT
To ensure the unit works correctly, the system needs a minimum
volume of water. The minimum water content is determined on the
basis of the unit's cooling or heating capacity (for heat pumps) in the
design of the unit, multiplied by the coefficient expressed in 3 l/kW. If
the water content of the system is below the minimum value calculated,
install an additional tank. However, remember that a high water content
in the system always goes to the advantage of comfort in the room, as it
ensures a high thermal inertia of the system
