3.1 PRELIMINARY INFORMATION
Operate in compliance with safety regulations in force.
For detailed information (dimensions, weight, technical
characteristics etc.) please refer to the TECHNICAL
INFORMATION section.
Use single protection devices : gloves, glasses ecc.
During positioning consider these elements :
technical spaces required for the machine and system
place where the machine will be installed
electrical connections
water connections
air / aeraulic ducts
Do not considerer these elements could decrease
performances and operational life of the unit.
3.2 FUNCTIONAL SPACES
Functional spaces are designed to:
guarantee good unit operation
Carry out maintenance operations
protect authorized operators and exposed people
Respect all functional spaces indicated in the TECHNICAL
INFORMATION section.
Double all functional spaces if two or more unit are aligned.
3.3 POSITIONING
Units are designed to be installed:
EXTERNAL
in fixed positions.
Limit vibration transmission:
use antivibration devices on unit bearing/supporting
points;
install flexible joints on the hydraulic.
Installation standards:
Safe accessible position;
avoid flood-prone places;
verify unit weight and bearing point capacity;
verify that all bearing points are aligned and leveled;
install the unit raised from the ground;
consider the maximum possible snow level
A correct circulation of the air is indispensible to guarantee the
good working order of the machine.
Avoid therefore:
obstacles to the airflow;
exchange difficulties;
leaves or other foreign bodies that can obstruct the
exchange batteries;
winds that hinder or favour the airflow;
heat or pollution sources close to the unit (chimneys,
extractors etc);
stratification (cold air that stagnates at the bottom);
recirculation (expelled air that is sucked in again);
positioning below the level of the threshold, close to very
high walls, attics or in angles that could give rise to
stratification or recirculation phenomenons.
Ignoring the previous indications could:
energy efficiency decrease;
blocks due to HIGH PRESSURE (in summer) or LOW
PRESSURE (in winter).
3.4 FRESH AIR PROBE
The external probe allows to automatically change the unit
setpoint according to the external enthalpy (temperature +
humidity).
In this way is not possible to optimize the unit energy
efficiency .
In the winter operating also the defrosting times are optimized.
POSITIONING
The sensor must not be influenced by factors that can cause a
false reading (for example direct sun rays, air expelled by the
fan or other sources, contact with the unit structure or other
heat sources, accumulation of snow/ice).
Example for the positioning of the external probe:
A attic
B Underneath a terrace
C If attached to external wall provide a small roof
framework

4 - WATER CONNECTIONS
4.1 PRELIMINARY INFORMATION
Selection and installation of system components must be
carry out by installer.
Following you will find some indications to integrate with what
is provided by the local regulations in force and by the good
technical laws.
4.2 COMPONENTS
CUT-OFF VALVES :
installed at inlet and outlet (both on the water technique
circuit as well as that of the hot domestic water) allow
maintenance operations without having to empty the
system .
THERMOMETERS AND MANOMETERS :
installed at entry and exit of the main elements facilitate
inspection and maintenance.
AN AIR BLEED VALVE :
installed in all of the highest points of the system allowing
the venting of the circuits air..
DRAINAGE TAPS :
installed in the lowest points of the system to allow
bleeding.
EXPANSION TANK :
It keeps a correct system pressure when the water
temperature changes. It must be dimensioned as a
function of water content.
WATER FILTER :
if not present on-board the machine, must be installed
immediately in the water input of the unit, in a position that
is easily accessible for cleaning.
The filter never should be removed, this operation
invalidates the guaranty
SUPPORTI :
The hydraulic pipes weight mustn’t burden on the unit
connections ..
FLOW SWITCH
The flow switch must be present as a component of the
system
4.4 WATER QUALITY
The water quality can be checked by qualified personnel.
Water with inadequate characteristics can cause:
pressure drop increase
energy efficiency decrease
corrosive symptom increase
Water quality: acceptable values
4.5 RISK OF FREEZE
If the unit or the relative water connections can be subject to
temperatures close to 0°C adopt measures for prevent risk of
freeze.
For example:
Mix water with ethylene glycol
Safeguard the pipes with heating cables placed under the
insulation
Empty the system in cases of long non-use and check that:
there are no closed taps present that could trap water
even after emptying
there are no low points in which water can stagnate
even after emptying; carry out any blowing required .
4.6 ANTI-FREEZE SOLUTION
4.3 OPERATION SEQUENCE
Before connecting the unit, carefully wash the system by filling
it and emptying it several times with clean water.
Ignoring this operation will lead to several filter cleaning
interventions and at worst cases can cause damages to the
exchangers and the other parts.
Execute leakage test before isolate the pipes.
To avoid heat dispersions and formation of condensate isolate
all the pipes. Leave various point of service free (wells, ventholes etc ).
Consider that the use of anti-freeze solution determines an
increase in a pressure drop.
Make sure that the glycol type utilized is inhibited (not
corrosive) and compatible with the hydraulic circuit
components (pump etc).

OPTIONAL
PUMPING STATION
Available in the versions:
Single pump
Double pump
in this configuration one pump acts as backup of the other.
The microprocessor automatically balances the operating
hours of both the pumps and, in case of failure, the unit
signals the lockout of the pump out of use.
Hydropack with 2 pumps
the pump operating acts in parallel. Thanks to this modular
structure, the water flow-rate can be automatically reduced
if the temperature increases over the operating limit.
This device is very useful during starts-up, weekend
pauses, and after a long period of inactivity. When the
water temperature of the hydronic circuit is very high,
possible blocks for overcharging are avoided, as well as
the consequent interventions of specialized personnel for
the assisted start-up. In case of failure of one pump, the
unit continues to operate guaranteeing the 60% of the
nominal flow-rate.
INERTIAL STORAGE TANK
It is available in the standard version and in the primary/
secondary version to respond to different types of systems.

4.11 FREE-COOLING - OPTION
When the temperature of the fresh air is lower than the temperature of
the return water of the system, the free-cooling version lets you recover
cold from the external environment, reducing the work of the compressors all the way down to nothing.
USE OF ANTI-FREEZE SOLUTIONS
The heat carrier used in the systems that include a Free-Cooling devi-
ce require a glycol solution (usually an ethylene type). This substance
is required because the Free-Cooling units are intended to be installed
where the temperature can drop to very low levels during certain times
of the year. The percentage of glycol in the solution depends on the
low temperatures that can be expected in the place of installation.
Therefore, this parameter is at the discretion of the system designer.
Summer
cooling of the solution is ensured by the refrigerating cycle with
operation of the compressors (C) as in a traditional chiller ;
the Free-Cooling (Bh) coils are not involved.

The energy savings variable between 0 and 100%, based on the tem-
perature difference between fresh air and the system request.
If the unit detects that the fresh air temperature (Ae) is suitable:
1. it inverts the position of the 3-way valve (V3), forcing the
solution to travel through the Free-Cooling coils (Bh) before
reaching the evaporator (Ev);
2. it sets the fans (Fa) at maximum speed to obtain maximum
cooling of the solution from the fresh air;
3. the solution thus undergoes an initial cooling which is free and
natural;

4. the remaining cooling is provided by the refrigeration cycle,
with compressors in stepped operation (power absorbed
proportional to the degree of stepping);
If the temperature of fresh air increases, the microprocessor will automatically revert operation to summer mode, ensuring the same conditions requested by the user.
INTERMEDIATE SEASON
Winter
The three way valve (V3) is in the same position as in the previous
case;
the temperature of the fresh brings the solution at the outlet of
the Free-Cooling coils (Bh) to the temperature required for
use;
the microprocessor control completely deactivates all com-
pressors (C), providing all cooling power at no cost, as opposed to standard units;
if the difference between the temperature of the fresh air (Ae)
and that required for use is such that the temperature of the
solution at the outlet of the Free-Cooling coils (Bh) drops
below the set point required for use (which does not compromise unit safety, because of the glycol in the solution), the
microprocessor modulates fan speed (Fa), turning them off if
necessary. When the fans are off, if the temperature (Wo)
continues to drop, the 3-way valve (V3) positions itself as in
summer operation, changing to digital and allowing the set
point to be maintained.

4.12 ENERGY RECOVERY - OPTION
Partial energy recovery
The use of a desuperheater makes it possible to recover, free
of charge, the heat that would otherwise be dispersed in the
environment. The partial heat recovery is composed of shell
and tube heat exchangers suitable for recovery of 25% of the
heat power dispersed by the unit (cooling and electrical power
of the compressors). If the temperature of the water to be
heated is relatively low, it is advisable to insert in the plumbing
circuit an adjustment valve to keep the recovery inlet temperature greater than 35°C to prevent condensation.
3) Cold request 50%, hot request 100% = circuit active in
cold+recovery (in this case the unit can provide only 50% of
the requested heat).
With the recovery active the condensing coil (Bc) is deactivated and condensation takes place in the total recovery (R).
With the recovery setpoint met, the condensing coil (Bc) is
reactivated, to perform condensation, via the solenoid valves
(Vr=off and Vc=on). In this case the recovery (R) acts as a
simple desuperheater.

and large potentials. The production of hot water is always of
lesser priority than the production of chilled water. The total
heat recovery is composed of shell and tube heat exchangers
suitable for recovery of 100% of the heat power dispersed by
the unit (cooling and electrical power of the compressors). The
unit with total recovery is capable of managing the recovery
temperature with thermal adjustment integrated in the microprocessor with two steps. The adjustment of power is managed based on chilled water and may have the following instances:
1) Cold request 100%, hot request 0% = circuit active only
