3.1 GENERAL INDICATIONS
When choosing the installation position, respect carefully the
following indications:
Fig. 5
-Make sure that the difference between the INTERNAL UNIT
and the UNIT OUTSIDE is not greater than 5.0 m.
- The appliance must be installed so that the influences of
adjacent structures and / or the effects of climatic conditions
details (snow, wind, etc. ...) do not compromise the product
operation and / or personal safety e of assets.
- Make sure that the space at the back of the unit is greater than
30 cm. The front must have more than 60 cm. of space.
- Ensure that there are no obstacles to free movement of air
through heat exchangers: A) do not dispose plants or animals
directly close to the air flow;
B) avoid installation in corners where it is usually deposited
dust, leaves and anything else that can reduce efficiency
of the exchangers obstructing the passage of air (Fig 5).
- Position the air discharge so that the flow is not hampered in
any way. In the case of strong winds, make sure the fan works
correctly, positioning the unit longitudinally, along a wall or using
one shielding

3.2 DISTANCES OF RESPECT (Fig. 7)
Respect the minimum spaces, so as to allow the correct
operation and all installation operations e maintenance.
3.3 ROOF INSTALLATION
- If the outdoor unit is installed on a roof, make sure of
level the unit. Make sure the roof structure is appropriate for
mounting the unit.
- Consult the local codes regarding the assembly on the
roof.
- If the outdoor unit is installed on the roof or on the external
walls, this could cause excessive noise and vibrations and
be classified as an unsuitable service installation.
3.4 ELIMINATION OF AIR WITH THE VACUUM PUMP
(Fig 8)
Air and moisture in the refrigerant system can cause effects
unwanted as shown below:
- Increased pressure in the system.
- Increased current consumption.
- Decreased refrigerant efficiency.
- Freezing and obstruction of the capillary pipes.
- Corrosion of the parts of the refrigeration system
- If the appliance must be suspended from a wall external, the
support must comply with the technical specifications.
The wall where the unit is to be installed must be in bricks or
material of similar consistency, otherwise it must be reinforced.
The support brackets must be stable, resistant and with an
adequate degree of protection against corrosion.
WARNING! Make sure of the bearing capacity of the part
on which the shelves and the anchoring system are placed
to the wall itself, depending on the weight of the appliance
to install.
- Do not install the appliance near sources of heat and / or
areas with fire hazards.
- Installation in areas with highly corrosive atmosphere
it is not allowed; in particular climatic conditions as in
near the sea, it is mandatory to provide for a duration of
lower life of the product and in any case a more frequent and
accurate maintenance.
- In the outdoor unit, from which the water from is eliminated
condensate, provide a suitable drainage and / or
channelling of the same, so as to avoid situations of
danger due for example to ice formation on
transit areas.
- The outdoor unit is designed to be installed outdoors and
it does not need a special base, however it must
be securely positioned on a support surface
horizontal of adequate bearing capacity and equipped with
special ones anti-vibration pads (Fig 6).
To avoid the above, the internal assembly and the tubes, placed
between internal and external group, must be tested for leaks
and purged to remove non-condensing elements and moisture
from the system. Check that each tube, (both the gas side tubes
and the liquid) between internal group and external group, has
been connected in the correct way and that all the wiring
necessary for the testing have been carried out. Remove the
valve cap on the outdoor unit. Make sure at this point that both
the gas valves are on liquid remain closed. Check the length of
the pipe and relative quantity of the refrigerant, for a correct
charge, check the superheat value. At the table values are
indicative. When changing places to the unit, perform the purge
with the vacuum pump. Make sure that the refrigerant inside the
conditioner is always in liquid state. The outdoor unit is supplied
with a charge of refrigerant gas R410A suitable for guaranteeing
correct operation up to one maximum distance of 5 meters from
the indoor unit. If you decide to install the 2 units at a greater
distance of 5 meters, make sure to add 20 g of refrigerant gas
per every meter more than piping (Tab. 3). For example, if there
are 7 meters of indoor and outdoor units add 40 g of R410A gas
to the pipe. In any case, never exceed 15 meters. Perform the
addition only after having carried out the vacuum in the pipes
that connect the 2 units, after which you can proceed with the
opening of the gas taps, mounted on the machine. 3.5
EVACUATION Connect the end of the charging hose to the
pump of the vacuum to evacuate the air from the pipes of the
indoor unit. Check that the "LO" knob on the pressure gauge
valve be open. Then run the vacuum pump. The time of
operation varies depending on the length of the pipes and the
pump capacity. When the desired vacuum is reached, close the
knob "LO" of the pressure gauge valve and stop the vacuum
pump. In conclusion, using a service valve wrench, rotate the
stem of the gas side valve counter clockwise to open it
completely. Loosen the flexible charge hose connected to the
service socket of the gas side to release the pressure, then
remove the tube. Replace the gas valve and nut cover service
and tighten well with an adjustable wrench. This procedure is
very important to avoid losses Plant Replace the service valve
caps on both the gas and fuel side from the liquid one and
tighten well. This completes the air purge procedure with the
pump of the vacuum, make sure that all the pipes are connected
in a manner correct and that the service valves of the gas and
liquid sides are completely open.
3.6 PUMP DOWN
This procedure is performed when the group must be moved or
assistance is provided to the refrigerant circuit. Emptying allows
you to collect all the refrigerant in the external group without
losses occurring.

WARNING! To make sure
to perform the procedure of
emptying with the group
in COLD MODE
3.7 RECOVERY PROCEDURE
- Connect a low pressure gauge with a hose to the
service port of the gas valve.
- Open the gas valve in half and empty the air from the
piping of the pressure gauge using the refrigerant gas.
- Completely close the liquid valve.
- Turn on the machine in cooling mode.
- When the pressure of the pressure gauge goes from 0
to 0.5 kg 2G cm (between 14.2 and 7.1 P.S.G.I)
completely close the gas valve and quickly switch off the
air conditioner.
The complete recovery of the refrigerant was thus carried

gradually increasing;
MANU (“P14” = 0): la caldaia esegue 5 tentativi di accensione
alla potenza di accensione indicata nel parametro “P31”.
Una volta ottenuta con successo l’accensione del bruciatore, la
caldaia esegue in autonomia un ciclo alla potenza minima “P0”,
di accensione “P1” e alla potenza massima “P2” per ottenere
una buona stabilità di amma, poi si porta in modalità di modica
della CO2 per permettere la taratura manuale.
L’impostazione del tipo di modalità (AUTO o MANU) viene
immessa nel codice di attivazione per il parametro “P14” nel
menù Parametri TSP.
