II.5.1 INSTALLATION SITE REQUIREMENTS
The installation site should be chosen in accordance with that set out in
the EN 378-1 standard and in keeping with the requirements of the EN
378-3 standard. When selecting the installation site, risks posed by
accidental refrigerant leakage from the unit should also be taken into
consideration.
II.5.1.1 Outdoor installation
Machines designed for outdoor installation must be positioned so as to
avoid any refrigerant gas leakage entering the building and posing a
hazard to people's health.
If the unit is installed on terraces or building roofs, adequate safety
measures must be taken in order to ensure that any gas leaks cannot
enter the building through ventilation systems, doors or similar
openings.
In the event that the unit is installed inside a walled-in structure (usually
for aesthetic reasons), these structures must be suitably ventilated in
order to prevent the formation of dangerous concentrations of
refrigerant gas.
II.5.2 CLEARANCE SPACES, POSITIONING
IMPORTANT!
Before installing the unit, check the noise limits
permissible in the place in which it will be used.
IMPORTANT!
The unit should be positioned to comply with the
minimum recommended clearances, bearing in
mind the access to water and electrical
connections.
The unit is designed for outdoor installation. The unit should be installed
to comply with the minimum recommended clearances, bearing in mind
the access to water and electrical connections. The unit should be
correctly levelled and positioned on a supporting surface capable of
sustaining its full weight. It must not be installed on brackets or shelves.

SECTION II: INSTALLATION AND MAINTENANCE
IMPORTANT!
The incorrect positioning or installation of the unit
could cause it to malfunction or produce increased
noise or vibrations.
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.
II.6 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.
IMPORTANT!
We recommend installing isolating valves that
isolate the unit from the rest of the system. . It is
essential to install square section mesh filters
(longest side 0.8 mm), offering suitable dimensions
and pressure drops for the system. 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 the isolate the unit from the
rest of the system. It is also advisable to install elastic connection joins.
○ It is essential to fit a metal mesh filter (square mesh of no greater
than 0.8 mm) 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.
