WINTER : the cooling cycle makes it possible to absorb energy
(heat at low temperature) from the external environment and to
transfer it to the area to be heated.
1. The compressor compresses the refrigerant fluid, placing it
at high pressure and high temperature.
2. The 4-way valve reverses the flow with respect to respect to
SUMMER operation.
3. In the plate exchanger, the water that returns to the system
absorbs heat from the refrigerant.
4. As it cools, the refrigerant condenses and becomes liquid.
5. The expansion valve causes a sudden drop in the pressure
of the refrigerant, which becomes very cold as its volume
increases.
6. In the external coil, the cold refrigerant evaporates and absorbs heat from the external air. In this phase, as the coil
cools, it may freeze. This is why the cycle is automatically
reversed periodically for a short time so as to defrost it

1.5 PRINCIPLE OF OPERATION
SUMMER: the cooling cycle allows the transfer of excess
indoor heat to the external environment.
1. The compressor compresses the refrigerant gas, placing it
at high pressure and high temperature.
2. In the external coil, the refrigerant is cooled, and the heat
is released into the environment by means of the fan. This
is why the coil needs to be kept clean and free of obstacles.
3. When it cools, the refrigerant becomes liquid.
4. The expansion valve causes a sudden drop in the pressure of the refrigerant, which becomes very cold as its
volume increases.
5. In the exchanger, the refrigerant evaporates and absorbs
the heat from the water that returns to the system, cooling
it.

3 - POSITIONING
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 points
• install flexible joints on the hydraulic connections
Choose the installation place according to the following
criteria:
• Customer approval
• safe accessible position
• technical spaces requested by the unit
• spaces for the air intake/exhaust
• 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
• max. distance allowed by the electrical connections
Prefer places where the unit doesn’t disturb the neighbours.
Avoid installations next to bedrooms or windows.
Avoid snow accumulations on batteries.
Protect the unit with an appropriate fencing to avoid the
access to a not authorized personnel (babies, vandals etc.)
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 CONDENSATE WATER
When a heat pump is running it produces a considerable
amount of water due to the defrosting cycles of the external
coil.
The condensation must be eliminated in a manner to avoid
wetting pedestrian areas.
With extensive very cold outdoor temperatures, condensation
could freeze and block the flow, causing a slow build-up of
ice; therefore special attention must be paid to eliminating
condensation, raising the unit off the ground and evaluating
whether antifreeze elements should be installed
3.5 FRESH AIR PROBE - OPTIONAL
The external probe allows to automatically change the unit set
point according to the external enthalpy (temperature +
humidity).
It is then possible to optimize the unit energy efficiency.
POSITIONING
The sensor should not be influenced by factors that can
distort the reading (eg direct sunlight, air exhausted from the
fan or other sources, contact with the unit structure or other
heat sources, accumulations of snow / ice).
Examples to position the external probe :
• A roof
• B under a terrace
• C if at free wall provide a
small roofing

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.
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 plant volume and temperature.
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
SUPPORTS
• 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
4.3 OPERATION SEQUENCE
1. Carefully wash the system with clean water: fill and drain
the system several times.
2. Apply additives to prevent corrosion, fouling, formation of
mud and algae.
3. Fill the plant
4. Execute leakage test.
5. Isolate the pipes to avoid heat dispersions and formation
of condensate.
6. Leave various point of service free (wells, vent-holes etc).
Neglecting the washing will lead to several filter cleaning
interventions and at worst cases can cause damages to the
exchangers and the other parts.
4.4 WATER QUALITY
The water quality is determined by the following factors, avoid
therefore:
• Inorganic salts
• pH
• Biological load (seaweeds etc)
• Suspended solids
• Dissolved oxygen
Water with inadequate characteristics can cause:
• pressure drop increase
• energy efficiency decrease
• corrosive symptom increase
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
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).
Do not use different glicol mixture (i.e. ethylene with
propylene)
4.7 WATER CONNECTIONS
• Take away the supplied connection union by acting on the
connection joint.
• Weld the union to the installation pipe.
• Perform the connection between the installation pipe and
the evaporator, using the joint.
Do not weld the system pipe with the connection joint attached.
The rubber gasket might be irreparably damaged.
