winds, typhoons and earthquakes. The appliance could fall and be damaged as
well as cause damage to property or physical injury. If installing in areas
prone to thunderstorms, take measures to protect the appliance from lightning.
Work on the refrigerant circuit must only be carried out by persons with a
valid certification, issued by an accredited body, certifying their competence
to handle refrigerants safely in compliance with the specifications in force
in the sector. Use a vacuum pump with a non return valve to evacuate the
system. Do not perform an air purge using refrigerant. Use deoxidised
phosphorous copper piping for the refrigerant (seamless copper alloy piping
and tubing). Keep the inner and outer surface of the pipes clean and free of
contaminants. Store the piping indoors and keep both ends of the pipes
sealed until it is time to flare or weld. Do not use any means other than
those recommended by the manufacturer to accelerate the defrosting process or
to clean the unit. The appliance must be placed in a room that does not
contain any ignition sources (e.g. open flames, gas appliances or electric
heaters). Weld the pipes purging with nitrogen to avoid oxidation. Keep
the interconnection cable away from the copper pipe. The temperature of the
refrigerant circuit is high. Note that the refrigerants are odourless. Use
only the refrigerants indicated in the manual. Recharge the refrigerant when
it is in the liquid state. After installation, verify that there are no
refrigerant leaks. Do not touch the components of the refrigerant line
during or immediately after operation of the appliance. There is a risk of
burns or frostbite. Install the connection joints and manifolds referring to
the installation manual. Install the drainage pipe according to the
instructions in this manual. Incorrect draining can cause water seepage or
flooding with possible damage to the home and other property. Insulate the
piping to avoid condensation.

General information
The direction of the flow of liquid is indicated with words or symbols on
the housing of the appliance. Always use the specified cables for all
electrical work. Connect the cables securely and secure them
in a stable manner to prevent the terminals from being damaged by external
forces. Incorrect electrical connection may cause overheating conditions and
may result in fire and electrocution. Install the electrical cables making
sure that they are not taut. Otherwise, they could break or overheat causing
smoke or fire. The cables must be arranged so that the control board cover
can close properly. If the control board cover is not closed properly,
corrosion may occur and the connection points on the terminals may become hot,
ignite or cause electric shock. Always disconnect all power supply circuits
before touching the terminals for any reason. It is advisable to install a
Class B or F differential magnetothermic circuit breaker on the power supply
line of the appliance. For electrical work, comply with the provisions of
the national electrical code, local regulations, current regulations and the
requirements contained in the installation manual. It is necessary to use an
independent circuit and a single power supply socket. Do not connect other
appliances to the same electrical outlet. Insufficient electrical capacity or
faulty electrical installation may cause risk of electric shock or fire.
Incorporate in the wiring an omnipolar isolator switch with a separation
distance of at least 3mm between all poles and a residual current device (RCD)
with a value greater than 10mA. Observe the domestic regulations. Replace
the fuses only with others of the same value and technical characteristics.
Install the appliance and its power cables at least one metre away from other
electrical equipment in order to avoid interference or noise. The appliance
must be stored in such a way as to prevent any mechanical damage. Consult a
qualified technician for unit repair or maintenance. Do not modify or alter
the safety or protection devices. Do not touch the appliance with wet or
damp parts of the body as to do so could lead to electric shock. Make sure
that the power is disconnected before performing any service or maintenance.
If you notice any anomalies (e.g. a burning smell), stop the appliance, turn
off the power switch and consult your dealer. Make sure that the air inlet
and outlet are not blocked as this could trigger the protective device that
stops the appliance. This appliance is intended for use on commercial
premises by experienced or suitably trained users This appliance is designed
to cool or heat spaces intended for the presence of human beings. It must not
be used to cool or heat food, plants, animals, machinery, equipment or works
of art. Install the appliance in such a way that the noise and heat is
generates does not disturb people living in the vicinity and does not affect
the growth of animals or plants. Read this manual carefully before using the
appliance to ensure its safe operation.

General information
aCAUTION DANGER When connecting refrigerant piping, keep substances or gases
other than the specified refrigerant from entering the unit. The presence of
other gases or substances can reduce unit performance and cause an abnormal
increase in pressure in the refrigeration cycle. This can lead to explosion
hazards and resulting injuries. Install the unit on a stable stand that can
support its weight. If the chosen stand cannot support the weight of the unit,
or if the installation is not performed correctly, the unit may fall and cause
injury and serious damage. Do not pierce or ignite the appliance. The
appliance must be placed in a well-ventilated room whose dimensions correspond
to those specified for operation. The product must be installed with
earthing in accordance with the law to avoid the risk of electrocution. Do not
connect the earth cable to gas or water mains, lightning rods or phone earth
cables. Install an earthing connection switch. Failure to install this can
result in electric shock. Do not operate the appliance if the protections
have been removed. Do not install the unit: – in a location that can be
exposed to combustible gas leaks. Any accumulation of combustible gas around
the unit may cause a fire hazard; – near the coast (except in the case of
corrosion resistant models); – near a source of hot water due to the presence
of caustic gas in the air; – in the presence of strong electromagnetic waves;
– in the presence of significant voltage flicker; – in the presence of acid or
alkaline liquid that evaporates; – in the presence of flammable materials or
gas. Wear the required PPE (protective gloves) during installation and
maintenance. High pressure piping poses a risk of burns during operation.

mCAUTION When installing the outdoor unit, take into account the installation side and the type of drain. If the unit is installed in high mountains, frozen condensate water will block the water drain outlet; in this case, remove the rubber cap from the reserve outlet. If this is still not sufficient enough for correct water drainage, open the other two pre-cut outlets and check that the water can drain properly. Make sure that the reserve outlet is opened from the outside to the inside and carefully assess the installation position before proceeding because once the outlet is opened, it cannot be closed again. Protect the cut hole to prevent insects or other animals from entering and damaging the components.

4 REFRIGERANT PIPING
4.1 Installation of the refrigerant piping
Below are the guidelines for compliant installation of the refrigerant piping
Put the outdoor unit in place Put the indoor unit in place Put the pipes in
place Blow with nitrogen Perform welding Make the connection to the units
Perform the tightness test Carry out pressing and pressurisation
To perform all the operations correctly, you need the following equipment:
Pipe cutter Flaring tool Tube bending machine Vacuum pump Digital
vacuum gauge Manifold and fittings Cylinder of nitrogen Electronic leak
detector with sensitivity according
to current regulations.
lWARNING Pay attention to the maximum measurements of the refrigerant piping.
See paragraph “2.5 Length of refrigerant piping” page 13 .
lWARNING Use deoxidised phosphorous copper piping for the refrigerant
(seamless copper alloy piping and tubing) compliant with local regulations.
Keep the ends of the pipes sealed until installation to prevent the ingress of polluting agents such as dust, water and dirt.
Fig. 22

Blow nitrogen through the sections pre-welded in the workshop to expel any dust. Pipes should only be cut using roller pipe cutters (do not use a hacksaw).
Dirt that penetrates the pipes when in use could clog the expansion valves, the capillaries or enter the compressor, causing the latter to malfunction.
lWARNING Use piping suitable for use with R410A.
lWARNING Be careful not to touch the components when connecting the pipes.
19
Eliminate any residual moisture in the lines. Copper plating, formation of
acid sludge, freezing of the laminating devices, formation of acids that
corrode metals and deteriorate the insulation of the electric motor can occur
in the case of non-compliant installation with the presence of moisture. See
paragraph “6.3 Vacuum operation” page 40
Avoid weld undercutting that cannot be inspected; all the piping must be
accessible for inspection.
aCAUTION To prevent the refrigerant pipes from oxidising during welding,
charge with nitrogen.
In case of laying the lines before making the connection to the units, keep
the ends sealed until the time of connection. It is good practice to pinch the
ends in case the lines are laid a long time before the connection.
aCAUTION Use only nitrogen as a cleaning agent.
If residual moisture is found when cleaning with the blowing of nitrogen, or
if a long time has passed between the laying of the lines and the connection,
proceed with the “triple vacuum”. This procedure consists in filling with
nitrogen and emptying twice before carrying out the final emptying operation.
Make sure that the pressure does not rise during this operation.
It is important that the joints are created to standard to ensure a good seal.
For more information see paragraph “6.1 Flushing the pipes” page 39 and “6.2
Gas leak test” page 39
lWARNING For connection of the lines, only “braze” welding is allowed.
Brazing (1) consists in connecting metal pieces with the help of a filler
metal without melting the pieces to be assembled. The filler metal penetrates
by capillarity between the pieces to be assembled. The filler metal must be
phosphorous copper or “rods of silver alloy”.

Fig. 23
Refrigerant piping
Welding must be done in a neutral atmosphere (nitrogen). An inert atmosphere
(free of moisture and oxygen) must be created inside the pipeline. In this
way, no oxide formations are created during welding

Refrigerant piping
lWARNING After connecting the pipes to the indoor and outdoor units, charge with pressurised nitrogen to perform a tightness test.
Fig. 26
mCAUTION Do not use or integrate existing pipes. The old refrigerant and oil
in the piping contain a large amount of chlorine which will cause the fluid in
the new unit to deteriorate.
lWARNING Do not use solenoid valves to avoid the backflow of oil.
4.1.1 Refrigerant piping connection
Remove the front panel in order to: connect the refrigerant piping, make the
electrical connections and carry out maintenance on the unit.
lWARNING Before connecting the pipes to the outdoor unit, check that they do
not contain water or contaminants. Flush the pipes with high pressure
nitrogen, do not use refrigerant from the outdoor unit under any
circumstances.
4.1.2 Connect the shut-off valves Stop valve The stop valves are closed when
the unit is shipped from the factory.

Refrigerant piping
4.2 Thermal insulation of the pipes
Insulate the refrigerant and gas piping separately with insulating
polyethylene foam materials. Incorrect or missing insulation causes
condensation and subsequent dripping. For the connection parts of the indoor
unit piping, use heat-insulating materials that stick to the surfaces without
leaving gaps.
lWARNING Pipes laid in ceilings are particularly sensitive to condensation.
The thickness of the insulating material must be at least 15/20mm and able to withstand heat of 120°C. In conditions of high temperatures or humidity it is necessary to increase the thickness of the material.

Electrical connections
5 ELECTRICAL CONNECTIONS
5.1 Preliminary information
fATTENTION ELECTRIC DANGER All electrical connections must be done by a
licensed electrician according to the provisions of national and local
electrical codes. All electrical connections must be made according to the
wiring diagram on the panels of the indoor and outdoor units. If the
electrical system has serious safety problems, stop work immediately. Explain
the situation to the customer and refuse to install the unit until the safety
problem has been resolved. The power supply must be between 342 V and 456 V.
Insufficient power supply can cause malfunction, electric shock or fire.
Install overcurrent protection and a main power switch (see “5.2 Power supply
line” page 32). The power supply line must have a special protection
upstream against short circuits and earthing leakage that sections the system
with respect to other utilities. The technician must choose an approved
differential circuit-breaker or main circuit breaker. The air conditioner
must be properly grounded. All cables and conductors must be connected
securely. Loosening a conductor may cause the terminal to overheat, which in
turn may result in fire hazards or product malfunction. The electrical
cables must not touch or rest against the refrigerant pipes, the compressor or
any moving parts of the unit. The voltage difference between N and T must
not exceed 3 V. Higher values indicate suboptimal earthing and can cause
failure of the electronics.
fATTENTION ELECTRIC DANGER Before making electrical connections, turn off the
main switch of the system.
mCAUTION In order to remove the entire electrical panel: empty the
refrigeration circuit, taking care to recover the refrigerant; desolder the
pipe connected to the heat sink which cools the electrical panel disconnect
the electrical cables.
lWARNING The electrical system can be divided into two sub-families: the power
supply line and the communication bus network. Be careful during the
installation process.
lWARNING The insulation of the metal parts and air conditioner must comply
with the provisions of the national electrical code.
lWARNING Installation and wiring must be carried out by duly qualified,
certified and accredited professionals, in compliance with current
regulations.
aCAUTION The refrigerant piping, power cables and communication cables are
usually laid in parallel. The power and communication cables must be laid in
separate conduits to avoid signal interference. If the power supply is less
than 10A, the two conduits must be at least 300 mm apart. In case of a higher
power supply rating (between 10 and 50A), the two conduits must be at least
500 mm apart.
fATTENTION ELECTRIC DANGER Make sure that the unit is earthed. Keep the
earth wire away from gas and water pipes, lightning rods, telephone cables or
other earth wires. Incorrect earthing may cause electric shocks. Automatic
overcurrent and differential switches (earthing switches) must be used in
accordance with all the regulations in force
aCAUTION The outdoor units are based on DC inverter technology. Pay attention
to the type of power supply: the use of a UPS can damage the unit’s power
electronics.
31
aCAUTION Equip each outdoor unit with an electrical disconnector. The
installation of this is mandatory to ensure compliance with the safety
standards and to disable each module in case of failure, avoiding system
shutdown.
fATTENTION ELECTRIC DANGER The power line must be connected to the L – N
terminals of the internal sections. Be careful not to confuse the terminal
blocks for the power supply with those for the bus line.
fATTENTION ELECTRIC DANGER Separate power sources must be provided for the
indoor units and for the outdoor unit.
5.2 Power supply line
The cable must be connected to the terminal block using only crimped cables
with eyelet wire terminals
Electrical connections
The lower part of the clip (1) is fixed on the electrical panel, under the
terminals. The upper part (2) is supplied together with the other accessories.
Secure the top with the screws (3) supplied. If the cross-section of the cable
(4) is less than 10 mm2, fix the cables together If the cross-section of the
cable (4) is greater than 10 mm2, fix the cables separately. When stripping
the outer insulation sheath, make sure that the length of the stripping plus
the length of the terminal is between 100 and 200 mm
3
4 2
1 Fig. 48
Fig. 47
aCAUTION First connect the power cord and terminals, then secure the cables.
When installing the main power cable, strip the proper amount of insulation
according to the method of attachment and positioning of the cable clip. When
tightening the three screws, the twist length must ensure that when 100N of
force is applied on the cable, the sagging is less than 2mm. Excessive
tightening of the screws can damage the protective cover of the power cable.

Electrical connections
aCAUTION The refrigerant pipes, the signal wires connecting the indoor units
and the cables connecting the indoor units to the outdoor unit are in the same
system. If the power cable is parallel to the signal line, install them in
separate distribution ducts and leave enough space. (Reference distance: 300
mm when the current rating of the power cable is less than 10 A, or 500 mm for
50 A).
5.3 Communication bus network
The cables of the bus network (transmission line) must be laid in such a way
as to avoid electromagnetic interference.
aCAUTION Do not lay transmission and power cables in the same conduit.
Connect the cables as follows:
The combinations between internal and external sections must be the same in
terms of the refrigeration connections and electrical connections.
Use the “in and out” type of connection even if the lines work with
connection in parallel.
In case of connection with a controller of a higher level (centraliser), a
transmission line is required between each external line.
Do not connect the power cables to the terminal block of the bus network.
Do not perform joints but only carry out soldering using a heat shrink
sheath. Respect the lengths indicated in the technical manuals.
Shunt boxes are not allowed.
Correctly address the components of the system.
The cable used must be of a type suitable for data transmission with RS 485.
If not suitable for such use it can cause interference and difficulties in the
transmission of packets.
The insulation and voltage characteristics of the cable must be in
accordance with the electrical regulations in force.
The insulation of the cable must have flame or fire retarding
characteristics, commensurate with the electrical standards of reference for
the type of system used.
The cable must be laid to standard.
The cable must be laid separately from other cables, especially from power
cables or from cables of different voltages.
The cable must be laid far from cables or devices that can cause
electromagnetic interference.
The RS485 serial line must always be of the “Bus
Electrical connections
in-out” topology. Different topologies are not allowed (star or ring-type,
etc.).
The serial line must be laid by personnel trained and qualified in data
communication networks.
Connecting the shield
For the bus network, use 0.75 mm3 3-pole shielded cables. Using other types
of cables may result in interference or malfunctions.
The shield of the bus cable used for serial communication must be connected
to an earth free from interference.
The shield must be earthed at one point only.
The continuity of the shield must be ensured the entire length of the bus cable.
l
WARNING These requirements are generally valid. In some areas characterised by the presence of particular types of EMI coupling, a different type of connection of the shield may be required.
aCAUTION Make sure that the metal braiding of the cables does not touch any
live points. Use dedicated wire terminals.
Outdoor unit connections
A wrong connection can cause malfunctions. Electrical connections: seal the
electrical connections with insulating material to prevent condensate from
forming.
aCAUTION Do not earth communication cables P and Q.
The shielding networks of the communication cables must be connected together and earthed. For earthing, join the adjacent metal casing with terminals P, Q, E of the electrical panel of the outdoor unit.

6 STARTING UP THE SYSTEM
6.1 Flushing the pipes
The refrigerant piping must be flushed with nitrogen to remove dust, moisture
and other particles that could cause the compressor to malfunction if not
eliminated before the system is put into operation. Flushing should be carried
out after completing connection of the piping, with the exception of final
connections to indoor units.
lWARNING Flushing must be performed before connecting to indoor units.
aCAUTION Use only nitrogen for flushing. Do not use carbon dioxide since it
can create condensation in the pipes. Oxygen, refrigerant, flammable gases and
toxic gases must not be used for flushing. The use of such gases can cause
fire or explosion.
The flushing procedure is as follows: 1 Cover the inlets and outlets for the
indoor units to
prevent dirt from being sucked inside during flushing of the pipes. 2 Attach a
pressure reducing valve to the cylinder of nitrogen. 3 Connect the outlet of
the pressure reducing valve to the inlet on the liquid (or gas) side of the
outdoor unit. 4 Use blanking plugs to block all openings on the liquid (gas)
side except for the opening on the indoor unit (N6) which is farthest from the
outdoor unit. 5 Begin to open the valve of the cylinder of nitrogen before
gradually bringing the pressure to 0.5bar. 6 Allow the nitrogen to flow to the
opening of the indoor unit (N6). 7 Clean the opening with a cloth until no
more dirt or moisture comes out. Check with a clean cloth that the opening is
clean. 8 Seal the opening
Repeat steps 7 and 8 for all the outlets of the indoor units, from the
furthest to the closest to the outdoor unit.
9 Seal all the openings.

6.2 Gas leak test
A leak test must be carried out before the system is put into operation, in
order to avoid failures caused by the leaking of refrigerant.
aCAUTION Use dry nitrogen only. Do not use oxygen, flammable gases and toxic
gases. The use of such gases can cause fire or explosion.
mCAUTION Make sure that all the stop valves of the outdoor unit are closed
tightly.
Connect the outdoor unit and indoor units and create a vacuum in the piping
at -0.1Mpa.
A vacuum pump with a minimum capacity of 80-120 litres/ minute is required for
vacuum operations. If the required value is not reached, it is recommended to
carry out further drying using the triple vacuum procedure.
Fill the internal piping with nitrogen at 0.3Mpa via the needle valve of the
liquid stop valves (3). Leave to act for at least 3 minutes.
Do not open the liquid (1) or gas (2) stop valves. Observe the pressure gauge
to check for significant leaks. If there is such a leak, the hand of the
pressure gauge will go down rapidly.
Fill the system with nitrogen at 1.5Mpa and leave to act for at least 3
minutes.
Observe the pressure gauge to check for small leaks. If there is such a leak,
the hand of the pressure gauge will go down rapidly.
Fill the system with nitrogen at 4.0Mpa and leave to act for at least 24
hours.
Write down the initial room temperature (Ti).
A change in the room temperature of 1°C corresponds to a change in the
pressure of the nitrogen charged in the line of 0.01MPa (0.1bar). Use this
correction factor when comparing the final room temperature (Tf) with the
initial one (Ti).
39
Starting up the system
Example: Initial room temperature (Ti) after charging with N2: 26°C Nitrogen
pressure (Pi) in the system at 26°C: 4.0 MPa (40bar) Final room temperature
(Tf) after 24 hours: 18°C Nitrogen pressure (expected) at final room
temperature (Tf) after 24 hours:
= 40 bar + (18°C-26°C) x 0.1bar/°C = 40 bar – 0.6 bar Pf = 39.4 bar If the
actual final pressure (Pf) is evidently lower than the expected final pressure
(Pf) (< 39.4 bar), there is a leak that needs to be found.
Perform vacuum drying. See paragraph “6.3 Vacuum operation” page 40
If drying cannot be carried out immediately, reduce the pressure to 0.5-0.8MPa
until drying is possible.
6.3 Vacuum operation
Perform drying to remove moisture and non-condensable gases from the system.
The elimination of moisture prevents the formation of ice and the oxidation of
copper pipes or other internal components. The presence of ice particles in
the system could cause malfunctions. Oxidised copper particles can cause
damage to the compressor. Non-condensable gases present in the system could
cause pressure fluctuations and lead to poor performance of the heat
exchanger. The combination of a vacuum operation and a gas leak test
facilitates the detection of leaks.
mCAUTION Before vacuum drying, make sure that all the stop valves of the
outdoor unit are closed.
12

4 5
Fig. 64
In order to detect nitrogen leaks, proceed as follows: it is possible to
hear a noise when there are significant leaks; put your hands on the joints
to feel for gas leaks; apply soapy water over the joints made. If bubbles
form, there are small leaks. check all the joints with a leak detector.
mCAUTION Use only one-way valves. Once the procedure is complete and the pump
stops, the low pressure can draw the lubricant from the pump into the system.
The same situation arises if the pump suddenly stops during the procedure.
Mixing of the pump lubricant with the compressor oil can cause the compressor
to malfunction.
To perform drying, a vacuum pump is used to lower the pressure in the pipes
until all the moisture present evaporates. It is necessary to use a vacuum
pump capable of maintaining a pressure equal to or less than -756 mmHg
(recommended vacuum level: <750mTorr) below atmospheric pressure. At -755 mmHg
below atmospheric pressure, water reaches its boiling point at 0 °C. We
recommend using a vacuum pump with a discharge rate greater than 4 litres/s
and an accuracy level of 0.02 mmHg
To carry out the vacuum operation, proceed as follows:
Connect a three-way pressure gauge (1) to the gas pipe stop valve (2) of the
main unit via the low pressure pipe (B) and to the liquid pipe stop valve (3)
via the high pressure pipe (A) and to the vacuum pump (4) via the vacuum
refrigerant pipe (C).

6.4 Charging with refrigerant
aCAUTION Charge the refrigerant only after having done “6.2 Gas leak test”
page 39 and “6.3 Vacuum operation” page 40 .
4
Fig. 65
Activate the vacuum pump. Open the valves of the pressure gauge to start
creating a vacuum in the system.
After 30 minutes close the valves of the pressure gauge.
If within 5/10 minutes the pressure gauge returns to zero, there are leaks
in the system. Proceed with repair.
Open the pressure gauge valves again and continue drying for at least two
hours and in any case until a pressure difference of 0.1 Mpa is exceeded. Once
this pressure is reached, continue for another two hours.
Close the pressure gauge valves.
Stop the vacuum pump.
If the pressure in the piping has not increased after one hour, the
procedure is over. If the pressure has increased, there are leaks in the
system.
When done, it is possible to keep the high and low pressure hoses connected to
the pressure gauge and to the stop valves of the master unit for the purpose
of charging with refrigerant.
aCAUTION Do not charge more refrigerant than necessary because to do so can
seriously compromise the correct functioning of the refrigeration circuit.
aCAUTION Use only R410A refrigerant. Charging with other substances may cause
an explosion and fire.
mCAUTION When charging the refrigerant, wear suitable PPE such as gloves and
protective goggles.
mCAUTION Open the refrigerant containers slowly.
lWARNING Use only instruments and appliances designed for use with R410A
refrigerant.
lWARNING The refrigerant must be treated in compliance with the regulations in
force.

l
WARNING For each branch-joint (Y or branches) in the refrigerant line, 0.5 m must be added to the total length of the pipes.
Once the value has been obtained, proceed as follows:
Place a tank of R410A refrigerant on a scale. In this way the refrigerant will be charged in the liquid state.
l
WARNING The correct composition is in the liquid state, not gaseous. For this reason it is advisable to stop charging when approximately 5% by weight of the initial content remains in the cylinder. Otherwise there is a risk of transferring the refrigerant in its gaseous state.
Connect the 3-way pressure gauge (1) to the gas pipe stop valve (2) of the master unit via the low pressure pipe (B) and to the liquid pipe stop valve (3) via the high pressure pipe (A) and to the refrigerant tank (4) via the vacuum refrigerant pipe (C).

Fig. 66 Before opening the service valve on the R410A
cylinder, it is recommended to put the hoses under vacuum, using the special
pump, to avoid the introduction of air and other non-condensable products into
the refrigeration circuit.
aCAUTION Danger of freezing. Slowly open the tank and use PPE.
Open the three valves on the pressure gauge to start charging the
refrigerant.
Close the valves once the desired quantity is reached.
42
Starting up the system
In case the refrigerant tank is insufficient for a complete charge, close the
three valves on the pressure gauge, start the outdoor unit in cooling mode,
then open (C) and (B). Connect the yellow pipe to a new tank and resume
charging until the desired charge is complete. Close the valve (C) and (B).
aCAUTION Before starting the system, make sure to complete all the
checks/controls required before initial start-up (see paragraph “8.1 Startup
preparations” page 50) and make sure to open all the stop valves. Starting the
system with the stop valves closed can cause damage to the compressor.
FULL REFRIGERANT CHARGE If a full charge of refrigerant is required (e.g.
after moving/ replacing the unit or after a leak), the total refrigerant
charge will be the sum of the factory refrigerant pre-charge + the additional
charge.
dIT IS PROHIBITED TO mix different types of refrigerant
R410A refrigerant is chemically stable, of low toxicity and non-flammable, and
belongs to the family of HFCs. R410A is a mixture of R32 refrigerant (50%) and
R125 (50%), with properties very close to that of an azeotropic mixture (it
behaves almost as a pure gas) with a negligible glide temperature (about 0.2
Celsius degrees with the split system under normal operating conditions). It
is also neither explosive nor inflammable, it has low toxicity (safety lass
A1, like R22) and it is not corrosive under normal conditions. The permitted
limit of exposure is the same as that of R407C and R22.
R410A is a “nearly azeotropic” mixture of two refrigerant gases (R32 and
R125). The “nearly azeotropic” condition refers to a state in which the dew
point curve and the boiling point curve (gas/liquid equilibrium curves at
constant pressure) almost overlap. With this chemical characteristic, the
refrigerant mixture undergoes negligible changes in composition when a change
of state occurs (evaporation or condensation). Consequently, even when a loss
of refrigerant in the gas phase occurs, the composition of the refrigerant
undergoes a negligible change.
Therefore, in the event of small leaks of refrigerant, R410A can be treated in
the same way as pure refrigerant R22, and can be topped up in small
quantities. On the other hand, in case of replacement of a component of the
refrigeration circuit, or a more serious leak, the normal procedures must be
observed, recovering all the refrigerant fluid. After eliminating the leak or
carrying out the repair, the system must be completely evacuated to eliminate
the air and then recharged with virgin gas. The recovered gas cannot be
reused.
MAXIMUM LEVEL OF CONCENTRATION The calculation of the maximum concentration of
refrigerant is directly related to the space in which the refrigerant can
leak, and to the quantity of refrigerant charge. The unit of measurement of
concentration is kg/m3 (weight of the gaseous refrigerant that has a volume of
1 m3 in the space). The maximum permitted level of concentration must comply
with the applicable regulations and local standards. In accordance with the
European standards that apply, the maximum permitted concentration of R410 in
the space occupied by human beings is limited to 0.44 kg/m3.
PRECAUTIONS FOR REFRIGERANT LEAKS This air conditioner uses a harmless and
non-flammable refrigerant. The room in which the appliance is installed must
be large enough to prevent a refrigerant leak from reaching a critical
concentration. It is therefore important to take some essential precautions.
Critical concentration: maximum concentration at which freon is harmless to
humans. Critical concentration of refrigerant: 0.44[kg/m3] for R410A.
Check the critical concentration with the procedure below and take the
necessary measures.
Calculate the sum of the charge volumes (A[kg]) Total refrigerant volume of
10HP=refrigerant volume pre-charged in the factory + subsequent additions.
Calculate the room cubage (B[m3]) (minimum cubage).
Calculate the refrigerant concentration (A/B) Critical concentration.
Countermeasure in case of excessive concentration:
Install a mechanical fan to lower the refrigerant concentration below the
critical value (ventilate regularly).
If the room cannot be ventilated regularly, install a leak detection device
connected to the mechanical fan.

Maintenance
9 MAINTENANCE
It is good practice to periodically clean both the internal and external parts
of the appliance. This guarantees its proper operation and durability. Carry
out periodic maintenance of the appliance in accordance with the regulations
in force.
Maintenance must be carried out by qualified technical personnel. Improper
maintenance or service can cause electric shock, fire or water leakage.
fATTENTION ELECTRIC DANGER Before cleaning or maintenance, always switch off
the air conditioner and disconnect it from the power supply.
This unit contains R410A fluorinated gas. It is forbidden to release it into
the environment. The GWP (Global warming potential) over a temporal period of
100 years is equal to 2090 units As it does not contain chlorine atoms, this
mixture does not damage the ozone layer.
For equipment that contains fluorinated greenhouse gases in quantities of 5
tons of CO2 or more but in any case less than 50 tons, a test must be carried
out to check for the leaking of refrigerant once every 12 months. If a leak
detection system is installed, the test must be carried out every 24 months.
For equipment that contains fluorinated greenhouse gases in quantities of 50
tons of CO2 or more but in any case less than 500 tons, a test must be carried
out to check for the leaking of refrigerant once every 6 months. If a leak
detection system is installed, the test must be carried out every 12 months.
lWARNING Do not check or repair the unit yourself. Contact skilled
professionals to carry out checks and repairs. Do not use substances such as
petrol, thinners or chemical dust cloths to clean the appliance. This could
remove the top layer of paint. If the unit is dirty, soak a cloth in diluted
neutral detergent, wring it out to dry it and then clean the appliance with
it. Lastly, dry it with a dry cloth.
aCAUTION If a fuse has blown, replace it with one with the same
characteristics. Using electrical cables or copper wires can cause the unit to
malfunction or start a fire.
aCAUTION Do not insert fingers, sticks or other objects into the air inlet or
outlet. Do not remove the fan grille. The fan can cause personal injury when
running at high speed. It is extremely dangerous to check the unit when the
fan is turning. Always switch off the main switch before starting any
maintenance work. Check the unit’s supporting structure and base for any
damage after a long downtime. The unit could fall and cause personal injury.
Discharge the pressure before disassembly.
Below are some modes that do not represent malfunctions
The outdoor unit makes a hissing noise . It can be caused:
by expansion due to heat or by contraction due to cooling of the heat
exchanger, depending on the temperature variations;
at the beginning or at the end of the defrosting process, the 4-way valve
may emit a sound similar to that emitted by a flow of water which will be
amplified after a few minutes;
by the flow of refrigerant or the discharge of drainage water;
by operation of the drain pump (accessories on request).
by a change in inverter frequency operation
The heat exchanger of the outdoor unit discharges mist or water. It can be
caused:
by defrosting of the outdoor unit.
Mist coming out of the outdoor unit.
The heat produced by defrosting the outdoor unit evaporates the humidity on
the coil.
The power indicator of the indoor unit flashes. It can be caused:
by restarting after an abnormal shutdown;
by mode conflict;
by stopping of the fan to avoid spreading cold air.
Automatic starting or stopping. It can be caused:
by activation of the timer.
The system is not working. It can be caused:
by the lack of power;
by closing of the manual power switch;
by the presence of a blown fuse;
by the presence of a time schedule;
The air conditioner does not switch on immediately after pressing the ON/OFF
button on the remote control;
53
If the operation light is on, the system is operating normally. To prevent
the compressor motor from overloading, the air conditioner switches on 3
minutes after the switch-on control.
Insufficient cooling or heating capacity. It can be caused:
by dirt in the heat exchanger;
by blockage of the unit’s inlet, outlet or filter;
by low fan speed;
by the “fan only” operating mode;
by inappropriate setting of the temperature.
The direction of the fan is not the same as the one set.
The direction of air is not the same as the one on the user’s front display.
The direction of air does not oscillate, since the units are controlled by
the centralised controller.
The speed of the fan is not the same as the one set.
The speed of the fan does not change even when the fan speed adjustment
button is pressed. When the indoor temperature reaches the setpoint during
heating, the outdoor unit turns off and the indoor unit enters fan speed
silent mode, to avoid the blowing of air directly at the user of the room. The
speed of the fan does not change even when the button is pressed for another
heating operation indoors.
Dust and dirt in the unit
When the unit is used for the first time, because there is dust in the unit.
Strange smell from the unit
This unit will absorb the smells of rooms, items of furniture, cigarettes
and others, to then disperse them. Small animals that can enter the unit may
cause smells.
The fan of the ODU does not work
During operation. Check the speed of the fan motor to optimise operation of
the product.
Hot air can be felt when the indoor unit stops
There are different types of indoor unit in use in the same system. When
another unit is in operation, part of the refrigerant continues to flow
through this unit.
Maintenance
Switching from cooling mode to fan mode
To prevent the internal evaporator from freezing, the system automatically
switches to fan only mode and then switches back to cooling mode after a few
minutes.
If the temperature of the conditioned room reaches the set value, the
compressor switches off and the indoor unit switches to fan mode; if the
temperature rises again, the compressor will restart. This also occurs with
heating mode.
9.1 Maintenance after shutting the unit down for a long period
For example, at the beginning of summer or winter.
Check and remove all the objects that could obstruct the air inlets and
outlets of the indoor and outdoor units.
Contact maintenance personnel to clean the air filter and the casing of the
outdoor unit. Make sure that the air filter is clean and installed properly.
Connect the power supply 12 hours before the unit is to be used to ensure
that the unit operates smoothly. At switch-on, the user interface is
displayed.
9.2 Maintenance before the unit is shut down for a long period
For example, at the end of winter or summer.
Operate the indoor unit in fan mode for about half a day to dry the internal
parts of the unit.
Disconnect the power supply
Contact maintenance personnel to clean the air filter and the casing of the
outdoor unit. Make sure that the air filter is clean and installed properly.
