i-290 Inverter air/water heat pumps with axial fans
1. DESCRIPTION OF UNIT AND TECHNICAL SPECIFICATIONS
The i-290 heat pumps were designed for residential and commercial
applications. They are extremely versatile and prepared for heat pump
operation with hot water production for ambient heating and for sanitary use
at a temperature of 75°C. The refrigerant employed is R290 gas, which, thanks
to its low GWP, ensures a long term solution in terms of efficiency and
environmental sustainability. Use of the INVERTER-controlled brushless
compressor technology, coupled with electronic expansion valve, circulator
pump and variable speed fan ensures excellent performance, due to the
optimisation of the specifics consumption and the high modulating capacity,
which in turn translate into high COP and EER values.
1.1FRAMEWORK
All the units of the range are produced in hot galvanised sheet metal painted
with polyurethane powders in kiln at 180°C to assure the best resistance to
weathering. The frame is self-supporting with removable panels for easier
inspection and maintenance of the inner components. All screws and rivets for
outdoor installation are in galvanised steel.
1.2COMPRESSORS
Twin rotary hermetic inverter controlled DC compressors, are designed to
operate with R290, equipped with thermal protection and mounted on rubber
vibration dampers. The compressors are installed in a compartment separated
from the air flow to reduce noise. They are also equipped with crankcase
heater to prevent oil dilution and consequently galling. The compressors can
be inspected by removing the side and front panels of the unit, so that they
can be serviced even with the units running.
1.3AIR SIDE HEAT EXCHANGER
The air heat exchangers are made of copper pipes and prepainted aluminium
fins. The pipes are mechanically expanded into aluminium fins to increase the
thermal exchange factor. The shape of these exchangers allows a low air side
pressure drops and therefore fans can run at low speed (thus reducing unit
noise). As optional the coils can be supplied with a “SILVER LINE” to allow
greater resistance to acidity and salt spray resulting in increased
hydrophilic ability and performance compared to a battery with simple
aluminium fins. The air side exchangers are designed to minimise the
refrigerant gas charge.
1.4UTILITY SIDE HEAT EXCHANGER
The utility heat exchangers are the brazed plate type, made of stainless steel
AISI 304, insulated at the factory with closed cell material. They can be
equipped with anti-freeze electric heater (optional KA accessory). Each
evaporator is protected by a temperature sensor used as an antifreeze
protective probe which activates the circulator, even when the machine is
switched off, if the conditions imposed on the control occur.
1.5EC FAN
The fans are made of plastic, the axial type with airfoil blades. They are all
statically and dynamically balanced and are supplied complete with protective
grid. All electric motors used are brushless modulating to optimise the
evaporation/condensation pressure in summer/winter operation so as to allow
the correct operation of the machine. The motors are directly coupled and
equipped with integrated thermal protection with IP54 rating.
1.6COOLING CIRCUIT
The cooling circuit is made with components of leading international companies
and in compliance with UNI EN standard 13134 on brazing procedures. The
coolant is the new R290 (GWP equal to 3) ecological gas. The basic version of
the cooling circuit includes: 4-way cycle reversing valve, electronic
expansion valve, liquid separator integrated with the compressor, liquid
receiver (only for i-290 0112, 0115, and 0118 units), safety device (high-
pressure switch), pressure transducers to carefully measure evaporation and
condensing pressure, bidirectional metal mesh filters to avoid obstructions on
the lamination valve. The suction pipe is thermally insulated thanks to a
closed cell elastometric foam. A pressure test is performed to detect any
potential leakage and the unit is supplied already charged with the optimal
amount of gas for proper functioning.

the power supply from the unit, wait at least 5 minutes before performing any
operation on the machine to allow the condenser to discharge. Do not use
equipment to speed up the defrost process or for cleaning except for those
recommended by the manufacturer. The appliance must be placed outside, in a
place without continuously operating ignition sources (e.g. open flames, an
operating gas appliance or electric heater). Refer to Chapter 5.5. Cable ducts
and electrical conduits to the machine must not contain potential ignition
sources.
Do not perforate or burn. Do not make mechanical modifications to the unit.
There are some moving parts inside the unit. Use extreme caution when working
near them, even if the power supply is disconnected. In particular, pay
attention to the fan blades when removing the front protective grilles. Do not
touch or insert any objects into the moving parts. The compressor heads and
discharge pipework are at quite high temperatures. The pipes on the suction
side of the compressor, can reach very low temperatures. Uninsulated pipes can
cause burns or freezer burns: only handle these components when their
temperature is close to ambient. Be particularly careful when working near
batteries. Aluminium fins are very sharp and can cause serious injury.
After the maintenance operations, close the panels by fixing them with screws.
After maintenance or replacement of components, reconnect the cables in the
same position as in the factory. Routine maintenance operations can be carried
out with the machine charged, while in the case of extraordinary operations,
repairs or replacement of components and heavy work in the vicinity of the
machine (e.g. construction sites), drain the machine of coolant gas and move
it to a safe area if necessary (in accordance with Chapter 5.5). Insulating
materials are not self-extinguishing: remove them when working on the unit, if
necessary. Do not remove, replace or make illegible the adhesive labels on the
unit and packaging. Do not cover the labels after installation of the unit.

3.3LIFTING AND HANDLING
Handling must be carried out by qualified personnel, properly equipped and
with equipment suitable for the weight and size of the unit, in compliance
with current accident prevention regulations. It is recommended: 1.check the
weight on unit technical label or on table of technical data; 2.check that
when moving the unit there are no disconnected paths, ramps, steps, doors that
could affect the movement and damage the
unit; 3.check that the unit remains horizontal when moving; 4.during handling,
do not carry out abrupt and sudden manoeuvres in order to not destabilise the
unit; 5.before handling the unit, check that the equipment is suitable for
lifting and preserving the integrity of the unit; 6.perform lifting only by
one of the listed procedures; 7.before starting handling make sure that the
unit is in stable equilibrium. Note that the weight of the unit is
concentrated more on the side of the refrigeration circuit: take into
consideration the weight distribution of the machine when transporting it
manually with ropes, in order not to lift excessive loads and avoid damage or
personal injury. It is recommended to remove the packaging only after the
machine has been placed in the actual installation location. Dispose of the
different packaging materials in accordance with national regulations.
Before commissioning, carefully inspect the unit and packaging for damage or
refrigerant leakage.
Do not proceed with the start-up of the unit if damage was found during
transport. Immediately inform the Company of the problem. The company is not
liable for any damage to the product caused by handling and transporting the
unit in a manner not in compliance with this manual and the regulations in
force.

3.5POSITIONING AND MINIMUM TECHNICAL CLEARANCES
All models of i-290 are designed and constructed for outdoor installations.
The company is not liable for any damage to property, animals and/ or persons
resulting from failure to comply with the instructions on installing the unit
described in this manual. It is advisable to create an adequately sized
support base for the unit. The units transmit a small amount of vibrations to
the ground: however, it is advisable to place anti-vibration mounts between
the base frame and the supporting surface. It is preferable to install the
unit away from places sensitive to noise and vibration (e.g. windows and glass
panes). Always make an environmental impact assessment based on the power and
sound pressure data in chapter “TECHNICAL DATA” and the sound emission limits
according to the installation area of the unit, with reference to the DPCM of
14/11/1997. An assessment must also be made if the unit is installed near
workers, according to D. LGS. 81/2008 Art. 189 and following. To reduce
vibrations and noise, the use of rubber seals is recommended for wall
installation.
In case of hanging installation, it is necessary to make sure that the wall has been made with solid bricks, concrete or similar. The wall capacity needs to be enough to support al least four times the weight of the unit. The maximum installation height is 800 mm.
The support plane must have enough capacity to support the unit weight, which can be checked both on the technical label of the unit and on this technical manual under “Technical data” chapter. The support plane must not be inclined to ensure the unit works properly and avoid a possible overturning. The support plane must not be smooth, to avoid water/ice deposit as potential sources of danger.

i-290 Inverter air/water heat pumps with axial fans
Unit installation place must be free from foliage, dust, etc., which could
clog or cover the coil. Installation in areas subject to water stagnation or
fall, for example from gutters, should be avoided. Also, avoid areas subject
to snow accumulation (such as corners of buildings with sloping roofs). In
case of installation in areas subject to snowfall, it is advisable to place
the unit on a base raised from the ground by 20-30 cm, to prevent the
formation of snow accumulations around the machine, which can obstruct the
battery and the perforations on the side panels and base of the machine. It is
recommended that sufficient air exchange be ensured to dilute R290 gas in the
event of its accidental escape, thus preventing the formation of explosive
atmospheres. For this reason, a minimum distance (depending on the unit) must
be maintained from any openings or manholes, in which the gas could
accumulate. Respect national regulations for the installation of the machine.
The units are suitable for installation in urban, industrial, coastal and
rural areas. If the unit is installed in an environment with aggressive
atmospheres, the air sucked in by the fan may contain substances that can
cause damage to the panels, grilles and internal components of the unit. In
this case, the operating life of the unit will be limited.
Avoid installing the unit under covers of any kind, such as roofs, canopies
and similar.
It is prohibited to install the unit in a location below ground level (such as cellars, underground car parks, basement or underground work rooms, etc.).
It is very important to avoid recirculation between intake and delivery air, so as not to downgrade performance of the unit or even to interrupt its normal operation. This is why the minimum clearances shown below must be strictly guaranteed.

Obstruction or covering of ventilation openings on the top cover must be avoided. For strong wind installation place refer to the classification of the area according to the Beaufort table. If the value is > 7 (strong wind, average wind speed = 13, 9-17, 1 m/s) it is strictly necessary to keep the fan always powered, thus preventing involuntary rotation of the same. If the unit is installed at a distance of less than 1 km from coastal and maritime areas, the presence of salt and sand in the air greatly increases the likelihood of corrosion. Install the unit so that it is protected from direct sea wind if necessary, provide windbreaks on site (observing the minimum distances indicated).
In the event of side-by-side units, the minimum Lmin dsitance between them is 1 m
17
i-290 Inverter air/water heat pumps with axial fans
Covering with canopies or placing near plants or walls should be avoided to
prevent air recirculation.
In the event of winds stronger than 2.2 m/s the use of wind barriers is
recommended.
3.6DANGER AND SAFETY ZONES
The i-32V5 series units contain R290 refrigerant gas. The density of this gas
is greater than that of air, so in the event of leakage it tends to disperse
and stratify, accumulating in niches, depressions in the ground or underground
regions. It is mandatory to comply with the danger and safety zones given in
this manual, when installing the units. These zones have been designed in
accordance with EN 60079-10-1, estimating an appropriate refrigerant loss, in
order to guarantee the safety of the units in the installation area. A danger
zone is defined as a area around the machine in which, in the event of a
leakage of refrigerant gas, a flammable atmosphere is formed for a short time,
within which it is necessary to implement all the precautions described in the
manual. In the absence of specific standards or regulations, when using the
unit in an industrial or working environment, it is advisable to carry out the
classification of places with explosion hazards considering the ATEX Directive
1999/92 (Directive 89/391). There must NOT be any sources of ignition in the
danger zones, including:
· flammable gases and sprays, self-igniting powders; · electrical equipment
that is not suitable for use in potentially explosive areas (zone 2 according
to Directive 89/391); · naked flames, heated surfaces (maximum surface
temperature of 360°C) and processing by heat; smoking is prohibited, including
for elec-
tronic cigarettes; · sparks, electrostatic charges, direct and indirect
lightning effects, eddy currents and cathodic protection; · ignition sources
due to remote processes (ionising and non-ionising radiation); · permanent
electrical sources (switches, lamps, etc.) or other possible triggers; In
addition, danger zone must NOT: · include potentially dangerous areas or
elements such as wells, manholes, openings to the sewage system and other
openings to under-
ground places and premises (e.g. garages), river drains, power lines,
flammable deposits, electrical installations, etc.; · include doors, windows
or glass panes, to prevent the possible return of the gas inside the building;
· extending towards neighbouring residential properties, parking areas, public
access sites, roads or railways. A safety zone extending beyond the danger
zone must also be identified. Within the safety zone, in the event of a
refrigerant leak, the concentration of the gas in the air is typically below
the critical levels for the formation of flammable or hazardous atmospheres.
Compliance with the following provisions remains mandatory: · prevent
accumulation and stagnation in underground spaces, drains, manholes, cellars,
etc.; · do not place building vents inside or near the safety zone; · do not
use naked flames and other direct heat sources. In any case, comply with
national and local regulations for the installation of machinery (where
applicable) in order to prevent the formation of fire hazards and to prevent
gases from seeping underground into openings to the ground or floors below. No
structural modifications may be made in the danger and safety zones that would
alter their extent or change the behaviour of the air-coolant mixture. It is
also strictly forbidden to tamper with, alter, remove or compromise, even
partially, the functionality of the devices, guards and prescriptions provided
for the safety of property and persons. In this manual, different types of
outdoor installation are considered, as indicated in the following paragraphs.

3.6.4Flat roof installation
The installation configuration on a flat roof is similar to that on a free-
field ground, although some additional aspects must be considered: · place the
machine at a sufficient distance from side walls and protrusions, which must
therefore be beyond the safety zone; · ensure that the roof structure of the
building is solid; · choose a location where no accumulations of snow, dust or
foliage can form; · pay attention to noise emissions and maintain an adequate
distance from surrounding buildings;
20

· if high air velocities are detected, install the protections listed in the
previous chapter.
3.6.5Multiple installation
When installing several machines side by side, follow the above
configurations, maintaining a respect distance of L between each machine. As
an example, see the following respect zones (danger and safety) for the case
of a generic number “n” of units installed on open field terrain:

For other types of installation not covered in this manual, contact technical
support. If in doubt about the installation of the units, request a technical
assessment by the fire brigade or a fire prevention expert.
3.7PLUMBING CONNECTIONS
The plumbing connections must be made in accordance with national and/or local
regulations; pipes can be made of steel, galvanised steel, multilayer steel or
PVC. Pipes must be accurately sized according to the maximum water flow rate
of the unit and the pressure drops of the water circuit. All pipes must be
insulated with closed-cell material of adequate thickness. The chiller must be
connected to the pipes using new flexible joints, not reused ones. The water
circuit should include the following components.
· Well thermometers to monitor the circuit’s temperature. · Manual gate valves
to isolate the chiller from the water circuit. · Metal Y filter or a dirt
separator (installed on the return pipe) with metal mesh no larger than 1 mm.
· Loading group and exhaust valve where necessary.
When sizing the pipes, make sure not to exceed the maximum pressure drop on
system side reported in the technical data table in Chapter 12 (see useful
head). Connect the pipes to their fittings always using the key-to-key method.
Create a suitable drain for the safety valve. CAUTION: The installer has to
verify if the expansion tank fits with the real capacity of the installation.
CAUTION: The return pipe from the system must be at the “WATER INPUT” label
otherwise the evaporator may freeze. CAUTION: It is mandatory to install a
metal filter (with mesh no larger than 1 mm) on the return pipe from the
system labelled “WATER INLET”. Alternatively, it is possible to install a dirt
separator that guarantees a filtration degree of no more than 1 mm; in this
case is not necessary to install the Y-filter. If the flowmeter is tampered
with or altered, or if the metal filter or the dirt separator are not present
on the system, the warranty shall expire. The filter (or the dirt separator)
must be kept clean, therefore, after installing the unit, you must make sure
that they are still clean and check them regularly. CAUTION: All the units
leave the company supplied with flowmeter (installed in factory). If the
flowmeter is altered or removed or if the water filter and dirt separator are
missing from the unit, the guarantee shall expire. Refer to the wiring diagram
attached to the unit to connect the flowmeter. Never jumper connections of the
flowmeter in the terminal block. The heating system and the safety valves must
comply with the requirements of standard EN 12828.
3.7.1Characteristics of the circuit water
To guaratee correct operation of the unit, the water must be appropriately filtered (see the instructions at the start of this paragraph) and there must be only a minimum amount of dissolved substances. The maximum allowed values are shown below:

3.7.4Condensation drain system
All units of i-290 series are built in such a way that the base of the unit
acts as a condensate drip tray. A plastic fitting is supplied as standard, to
be connected underneath the base in the special provision for connecting a
drain pipe to channel condensate.

Gasket
Gasket
Drain fitting
Each unit is fitted with a hole on the base of the hydronic kit (on the side of the coil) for draining any condensation that may percolate from the plumbing pipes and water formed as a result of the defrosting process. The pipes are well insulated, condensation production is minimal. In the event of a leakage, refrigerant gas can escape from the unit through the hole in the base panel, so it is recommended that the condensate drain is always directed to an open place near the unit (within the danger zone defined in Chapter 5.5). If the unit is installed on the ground, it is also possible to direct the condensation into a bed of rubble or gravel for drainage. For typical free-field ground installation, please refer to the following pictures:

Caution: Do not obstruct the hole in the base panel for condensate drainage.
Especially in very cold climate regions, it is recommended to install
elevation supports in order to allow ice formation under the unit without
damaging it by freezing. In addition, when outside air temperatures fall below
0°C, it is recommended to install a heating element on the discharge pipe.
3.7.5System load
CAUTION: Supervise all filling/reintegration operations. CAUTION: Before
filling/reintegration the system, disconnect power to the units. CAUTION: The
filling / reintegrating of the system must always take place under controlled
pressure (max. 1). Ensure that a pressure reducer and safety valve is
installed on the filling/reintegration line. CAUTION: The water in the
filling/reintegration line must be properly pre-filtered from impurities and
suspended particles. Ensure that a removable cartridge filter and a dirt
separator are installed. CAUTION: Regularly check and vent the air built up in
the system. CAUTION: Install an automatic air venting valve at the highest
point of the system.

3.7.6System discharge
If the unit needs to be drained completely, first close the manual inlet and
outlet gate valves (not included in supply) and then detach the pipes on the
outside of the water inlet and outlet to drain liquid from the unit (to make
this operation easier, it is recommended to install two drain valves between
the unit and manual gate valves on the outside of the water inlet and outlet).

7. SOUND EMISSIONS ACCORDING TO EN 12102-1:2022
The sound levels are referred to units at full load operating under conditions
that guarantee a thermal capacity equal to that declared at a temperature of
7°C for average climate, in accordance with EN 14825:2022. The tolerance on
the value of the total sound power level is 2 dB (A). The value is calculated
according with EN 12102-1:2022 regulation used in conjunction with UNI EN ISO
9614-1:2009 which describes the test methods and sound power measurement
techniques with the intensimetric method. The sound pressure values are
calculated from the sound power level using UNI EN ISO 3744: 2010, considering
units operating in the open field.

8. OPERATING LIMITS
8.1EVAPORATOR WATER FLOW
The nominal water flow rate refers to a 5°C temperature difference between the
evaporator inlet and outlet. The maximum permitted flow rate features a 3°C
temperature difference while the minimum one has an 8°C temperature difference
at the nominal conditions as shown in the technical sheet. Insufficient water
flow rates can cause excessively low evaporation temperatures causing the
safety devices to trigger and stopping the unit and, in some extreme cases,
forming ice in the evaporator and resulting in serious failures to the cooling
circuit. For greater details, we have attached a table below with the minimum
flow rates for the plate heat exchanger to guarantee proper operation
according to the model (please note: the water flowmeter is applied to protect
against failed triggering of the antifreeze probe due to the lack of flow but
does not guarantee the minimum water flow rate required for correct operation
of the unit).
Model i-290
Minimum water flow to be assured in chiller mode (condition (1) technical
sheet) [l/s] Maximum water flow to be assured in chiller mode (condition (1)

Pay attention to the pressure levels of the hydraulic system: too low values
can cause malfunctions of the unit.
For very low hydraulic system pressure values, the flowmeter may show an
unstable reading, so it is recommended to have an automatic loading system or
a pressure monitoring system. It is periodically check the state of the
deaerator, especially if very high temperature differences are read between
the inlet and outlet on the water side, as the presence of air bubbles in the
circuit reduces the available water flow rate, altering the flowmeter reading.
As an approximation, and without any other measurement systems, the correct
flow rate to guarantee the best performance of the unit can be verified with
the circulator at maximum speed, by looking at the pressure gauges to check
the pressure difference between the return and discharge water on the external
plumbing fittings of the unit and making sure that this reading is equal to or
lower than the useful head indicated on the curves shown in Paragraph 6.2 for
the respective models.
8.2COLD WATER PRODUCTION (SUMMER MODE)
A minimum temperature of 5°C is allowed at the evaporator outlet: for lower
temperatures, contact the Technical Department. In this case, contact our
technical department for a feasibility study and evaluation of the
modifications to be made according to the requirements. A maximum temperature
of 20°C can be maintained at the evaporator outlet in steady-state operation.
Slightly higher temperatures can however be tolerated durient transients and
in the phases of operation.
8.3HOT WATER PRODUCTION (WINTER MODE)
When the system has reached steady state, the water inlet temperature must not
drop below 22°C: lower values, not due to transient phases or reaching steady-
state, can cause system failures and could possibly break the compressor. The
maximum outlet water temperature must not exceed 75°C. There could be failures
to the regular operation of the unit or, in more critical cases, the safety
devices could be triggered due to temperatures higher than those indicated,
especially if coupled with reduced water flow rates.

8.4AMBIENT AIR TEMPERATURE AND SUMMARY TABLE
The units are designed and built to operate in summer mode, with condensation
control, at outdoor air temperatures between 10°C and 46°C. In heat pump mode,
the allowed temperature range of the outdoor air goes from-20°C to +20°C
depending on the outlet water temperature as shown in the table below.

HAZARDS IDENTIFICATION Highly flammable gas. Vapours are heavier than air and
can cause asphyxiation due to reduced oxygen levels. Contact with the liquid
can cause frost burns.
FIRST AID MEASURES In high concentrations it can cause asphyxia. Symptoms may
include loss of mobility and/or consciousness. In low concentrations it may
have a narcotic effect. Move the victim to an uncontaminated area while
wearing self-contained breathing apparatus. Use oxygen or artificial
respiration artificial respiration if necessary. Keep the patient lying down
and warm. Call a doctor. Carefully rinse with plenty of water for at least 15
minutes. Wash immediately with plenty of water for at least 15 minutes.
Immediately remove contaminated clothing.
FIRE FIGHTING MEASURES Water spray, dry powder. Exposure to flames may cause
the vessel to rupture or explode. Cool down the containers with a water spray
from a safe position. Stop the product leakage if possible. Use water spray,
if possible, to abate the fumes. Move the vessels away from the area of the
fire if this can be done without posing any risks.
ACCIDENTAL RELEASE MEASURES Try to stop the leak. Evacuate personnel to safety
areas. Eliminate the ignition sources. Ensure proper ventilation. Avoid
entering sewers, basements, excavations and areas where accumulation can be
dangerous. Use personal protective equipment. Remain upwind. Try to stop the
leak. Ventilate the area.
HANDLING AND STORAGE Ensure sufficient air exchange and/or suction in the
working area. Do not smoke. Keep away from sources of ignition (including
electrostatic charges). Use only appropriate equipment, suitable for the
product. Do not inhale the gas. Close carefully and store in a cool, dry and
well ventilated area. Storage containers should be checked periodically. Do
not store with other oxidants in general or other combustible substances. All
electrical equipment in the storage area are compliant with the risk of
explosive atmospheres formation.
EXPOSURE CONTROLS/PERSONAL PROTECTION
OEL: data not available. DNEL: data not available. PNEC: data not available.
Filter masks can be used if the ambient conditions and duration of use are
known. Safety goggles. Work gloves. No smoking.
PHYSICAL AND CHIMICAL PROPERTIES Colourless. Odourless. -42,1 °C at atm press
