1 Premise
Theinstallationandmaintenanceofair-conditioningdevices
suchasthisonecouldprovedangerousduetothepresence
of cooling gas and live electrical parts within the appliance.
It would therefore be wise to leave the installation, initial
start-upandmaintenanceexclusivelytotrainedandqualified
fitters, naturally after having read and understood this
handbook. When in doubt contact the service assistance.
Maintenance such as cleaning and filter substitution may,
however, be carried out by the user in that such tasks are
neither particularly difficult nor dangerous.
Duringinstallationandmaintenanceallprecautionsspecified
in this handbook and on the labels inside each appliance
must be observed as should normal common sense and
also the security standards in force on the installation site.
Furthermore, it is always neccessary to wear gloves and
securityglasseswhenincontactwiththecoolingpartofthis
appliance.
Pay attention to avoid burns during welding.
IMPORTANT: Before making any electrical connections
and before carrying out maintenance jobs it is essential to
open the general disconnector in order to avoid electric
shocks.
For repairs only original spare parts available from you
supplier must be used.
These fixtures may not be installed in the presence of
explosive or flammable gases.

In order to insure that the appliance is installed correctly, it
is essential to follow all the guidelines specified in this part
of the handbook. If these instructions are not followed the
applianceiscorrect function cannot be garanteed. In such a
casemalfunctioncannotbeattributedtoproductqualityand
hence the manufactureris garantee is rendered void.
3.1 Location selection of internal unit
The internal unitis location must be selected so that:
- The bottom of the appliance is neither less than 2 m nor
more than 3 m from the ground.
- The wall onto which the appliance is to be fixed is strong
enough to support such a weight.
- Enoughspaceisleftaroundtheapplianceinordertoallow
theairtocirculatefreelyand topermit maintenanceofthe
appliance as specified in the overall dimensions.
- Neitherair-intakenorair-outletisobstructed;thepresence
of walls or barriers with in 2 m from the outlet of the
appliance, could result in air bypasses and a consequent
reduction in the applianceis output (fig. 1 - fig. 1 bis).
- Condensate drainage is facilitated.
- Theemissionofairdoesnothitpeopledirectly,especially
those within 1,5 m from the appliance.

3.2.2 Internal unit assembly
Once the plate has been fixed, assemble the internal unit
using the following preocedure:
a) If the connection lines are at the back of the appliance,
a100mmholemustbedrilledinthewallwithanoutward
5% gradient (fig. 4) in order to facilitate condensate
removal. The position of the hole is indicated in fig. 2.
The best procedure is to make a preliminary hole in the
wall with a 8-10 mm nail in correspondence with the
centre of the hole to be drilled and then bore the
definitive hole using a drill with a guided cup. If there is
an "external air intake" included in the appliance, then a
holemustbedrilledforthisalso,inthepositionindicated
in the instructions supplied with the accessory and
assemble it in accordance with these instructions.
b) Insert the condensate removal line, cooling line and the
wires for electrical connection or the raceway in which
they are contained into the hole.
c) Remove the applianceis front panel in the following
manner (fig. 5):
- remove the three screws from the air outlet and the
other two from under the upper door,
- grip the frontal panel from below, turn it upwards to
free it from the lower part,
- lift the panel in such a way as to unhook it from the
two hooks under the upper door.
d) Bend the lines to the right (fig. 6) in the direction of the
connections. Use a tube bending spring to avoid
"pinching" the lines.

h) Remove the stopper, lift the device slightly and lower it
in order to connect it to the plateis lower hooks resulting
in a perfectly sturdy fixture (fig. 10).
i) Pull the appliance downwards and to the side to check
that it has been hooked up properly to the plate.
j) Connect to the mains as indicated in paragraph 3.7.
k) Close the front panel once more, tighten the screws
inside the air outlet and the two screws within the upper
door.
l) Check once again that the unit is perfectly level or,
at most, that it slants 2 mm towards the side where
condensation is drained.
3.3 Location selection of external unit
The external unitis location must be selected so that:
- The appliance is protected from direct sunlight.
- The base is strong enough to hold the weight of the
appliance; if, in order to carry out maintenence jobs, it is
necessary to stand on the base, then the said base will
havetobestrong enough to hold both the person and the
appliance.
- The appliance remains above the base at a distance
equal to that of the maximum foreseeable snowfall.
- Theapplianceneverremainsexposedtoheavydownpours
(ascanhappenwhenadrainpipegetscloggedupandthe
gutter overflows).
- Sufficient space is left around the appliance to inable air
circulation and maintenance as specified in the overall
dimensions.
- Pathways are not obstructed.
- The appliance can be securely fixed to the base.
- Neither fumes nor noise emissions can disturb the
neighbourhood in any way. As regards noise levels, the
Hygiene Regulations in force on the site must always be
respected. If noise levels are too high, soundproofing
should be installed without obstructing neither air-
circulation nor maintenance.
- The appliance is facing prevalent winds according to fig.
11.
- Theapplianceisnotinaleewardpositionasregardsburnt
gas smoke stacks and does not undergo contact with
vapours and oily or corrisive gas emissions.
- The condensate can be easily removed (in the case of
heat pump appliances).
- The internal unit connecting lines (or internal units in the
case of the Multisplit series) are not longer than 15 m in
eachdirection(whenmorethan10m, thechargemust be
topped up with 25 g of R410A for each extra meter).
Furthermore, the maximum difference in height between
the external and internal unit (or in the case of Multisplit,
the internal units) is not more than 5 meters.
Theexternal unit must be perfectly horizontal and therefore
before going ahead with its positioning it is essential to
ensure that the support surface is perfectly level.
If the appliance has to be installed in an overhanging
position on the wall it is advisable to use an "Assembly

bracket for the external unitis wall-mounting" which is
available on request. As regards the assembly follow the
instructions enclosed in each respective box.
Wewouldalsoliketoindicatesomeprecautionstobetaken
during assembly:
In areas susceptible to snowfalls
By means of support walls or a base of metal sections the
appliance must be lifted above ground level at a distance
greater than the height of a maximum foreseeable snowfall
because:
- if the appliance does not work by heat pump, during the
thaw,thewatercouldgetintothesystemcausingdamage
to the electrical devices,
- if the appliance works by heat pump, the drifting snow
could obstruct the regular air circulation and make con-
densate drainage difficult.
Appliance assembly on ground level, roof, terrace, etc.
in not easily accessible locations
Thebasemustbelifted toavoid stagnantrain waterand dirt
accumulation underneath the appliance. It is therefore
advisabletoraisetheapplianceapproximately15cmoffthe
groundbymeansoftwosmallwallsontowhichtheappliance
is fixed with two anchor bolts. The above is not necessary,
however, if the appliance is to be installed on a balcony as
balconies already slope to aid rainwater drainage and are
usuallyfoundinfairlyprotectedlocationshencethereshould
be no danger of dirt accumulation under the appliance.
Onarigidmetalbase(Brackets,metalsupportsections,
etc.)
In this case the appliance must always be fixed to the base
by means of elastic vibration-damping blocks (not supplied
with the appliance) underneath the four support points
which are selected in relation to the applianceis weight.
Furthermore, the base must be rigid enough to avoid
amplifying the vibrations caused when the appliance is
running.
Heat pump appliances
When the heating is on, a condensate or water is produced
in the external unit due to defrosting. Such water must be
eliminated to avoid stagnation. In particular, when the
appliance is assembled directly on the ground a drainage
channel should be made around the base of the appliance
which depends on the drainage system running from the
building. If the appliance is installed on a balcony it is
possible to position it over a tray in galvanized sheet iron or
betterstillinstainlesssteel(notincludedwiththeappliance)
which remains above ground level and which is equipped
witha drainpipe fromwhichthecondensate can be madeto
flow using the most opportune method (for example, into a
gutter).
Furthermore, even if the appliance is resistant in inclement
weather, itshouldbeassembledinalocationwhichremains
protected or it should be covered with its own roof which
permits the air to circulate freely through the appliance.

48
3.4 External unit assembly
After checking the suitability of the base (if prepared by a
third party) mount the external unit adopting the following
precedure:
a) Position the appliance on the base using the elastic
vibration-damping blocks if necessary.
b) Tighten the anchor bolts slightly.
c) Check that the appliance is horizontal in both directions
(fig. 12). If necessary, shim the supports until the
appliance is level.
d) Tighten the anchor bolts.
e) Open the attachment access door (fig. 13).
f) Connectupthecoolinglinesaccordingtoparagraph3.5.
g) Connectuptheelectricallinesasspecifiedinparagraph
3.7.
h) Reassemble the access door to the connections.

3.5 Laying and connection of cooling lines
IMPORTANT:Thepresenceofdirtorwaterinsidethepipes
to be used for the cooling lines could have a negative effect
onthe applianceiscorrectrunning. Normal copperpipesfor
thermohydraulic purposes do not offer the necessary
garantees for such a task. It is therefore essential to use
copper pipes for cooling purposes only which have
been cleaned and sealed within the factory. Such pipes
are annealed and delivered in rolls with the ends sealed.
Before assembling and after cutting off the required pieces
it is essential to seal both the ends of the roll and of the cut-
off pieces. Furthermore, the installation may be quickened
by using preinsulated refrigeration copper pipes which do
not require further lagging.
Granted that the pipes employed have to have the same
diameters and thicknesses as indicated in paragraph 2.2
"Technical Particulars", the installation and connection of
the lines must be carried out according to the following
procedure:
a) Identifytheshortestroutelinkingtheinternalandexternal
unit creating as few bends as possible (the shorter the
routeandthefewerthebends,thebettertheapplianceis
output). The length of the internal unit connecting lines
(or of the lines connecting up all the internal parts of the
Multisplit) must not be more than 15 m in each direction
(inanycase,for morethan 10mitisnecessary totop up
the charge with 20 g of R410A for each extra meter).
b) Cut off the required piping - it is better to cut off a little
more than required - and seal the ends.
IMPORTANT: The pipes should on no account be cut with
a saw as the shavings could get into the piping. The cutting
should therefore be carried out using a wheel pipe cutter
(fig. 14).
c) Insert the pipes into the lagging sheaths if preinsulated
pipesarenotused.Eachsheathendmustbejoinedand
sealedwithadhesivetape.Thelaggingsheathsmustbe
made of polyurethane closed cell foam and must have
the following characteristics:
- maximum trasmission coefficient: 0,45 W(Kxm2) or
0,39 kcal/(hx°Cxm2),
- the liquid lines must have a thickness of at least 7
mm,
- the gas lines must have a thickness of at least 10
mm. Avoid putting both lines into the same lagging:
the applianceis efficiency could be compromised as
a result.
d) Lapthelineswiththeracewaywithinwhichtheelectrical
cables are housed (see paragraph 3.7) fixing it with
adhesive tape or plastic clamps at regular intervals.
e) Laydownthe piping from the internal unit through tothe
externalunit(orviceversa)makingsurethatthelagging
doesnot get damagedinanyway when passedthrough
the walls.
f) If the piping is not connected up to the appliance
Fig. 14

50
immediately, before leaving the site remember to:
- seal the ends of the piping,
- Askthepersoninchargeofthesitetomakesurethat
the piping does not get squashed, bent or damaged
in any way.
g) The piping and the appliances (internal and external
units) are connected by means of binders. After the
piping has been cut and the nut which is found on the
connection has been inserted onto the piping (fig. 15),
thepipingmustbebindedinaccordancewiththenorms.
h) In order to tighten each joint it is necessary to:
- grease the thread with refrigeration oil (do not use
other types of oil),
- close the joint initially by hand,
- tighten the joint with a dynamometrically calibrated
spanner with the following torque values:
- 14“18Nxm(1,4“1,8kgxm)forlineattachmentsfrom
6,4“ 6 mm.
- 33“40Nxm(3,3“4,0kgxm)forlineattachmentsfrom
9,5“ 10 mm.
- 50“60Nxm(5,0“6,0kgxm)forlineattachmentsfrom
12,7“ 12 mm.
IMPORTANT: To avoid deforming the internal unitis
attachments when tightening, hold the welded part of the
joint with a spanner and tighten the other part with the
dynamometric spanner.
i ) Once the attachments have been tightened, the lineis
seal must be tested. In order to test the seal a cylinder
ofanhydrousnitrogenisconnectedtotheexternalunitis
gas pipe service connection (fig. 16) (after having
unscrewed the cap) (it is connected to the service
connections in the case of the Multisplit external units)
by means of a flexible with a 1/4" attachment and a
pressure reducer.
Open the cylinder and the pressure reducer until the
pressurein the circuitreaches3 bars andthenclose the
cylinder.Ifthepressuredoesnotdescendafter3minutes,
thismeansthattherearenomajorleaksandthepressure
canbe raised to 15bars.After the cylinder isclosed,the
pressuremustremainconstantforanother3minutes.In
any case, to be completely sure it is advisable to apply
a solution of soap suds and check that bubbles do not
formedinthesolution. Ifthepressuredescendsandthe
solutiontestgivesnoresults,insertsomeR410Aintothe
circuitandidentifytheleakagebymeansofaleakfinder.
Since there should be no weldings in the system, the
leaksarenearlyalwaysfoundaroundthejoints.Elimina-
te all gas leaks by tightening or repairing the joints and
repeat the seal test. Once the operation has been
concluded,reassemblethecaps,checkingcarefullythat
they have been closed properly.
IMPORTANT: In the case of Multisplit this operation must
becarriedoutonalltheconnectionsoneaftertheother.The
search for gas leaks must be carried out each time on the
circuit which depends on the connection in question.
j) Once the seal test has been passed, every trace of air,
nitrogen and humidity must be completely extracted
from the circuit. Lower the pressure within the circuit by
meansof a vacuum pump until the pressure reaches an
absolute value equal to 50 Pa and, leaving the pump

a search for possible leakages.
- Once the suction has been concluded, remove the

k) After opening the relevant cap, slowly open the tap on
the intake line and also the tap on the liquid line which
are found in the external unit, in order to allow the
diffusion of the cooler within the appliance.
3.6 Laying and connection of condensate removal
lines
3.6.1 For models 12 - 15
The appliance features an automatic system that
automatically drains any condensate fed by gravity (or a
pump) to the outdoor unit.
In the heat pump version, connect the fitting provided so
the water produced in defrosting mode can be discharged
into a drain.
The indoor unit must be provided with its own condensate
drainage line. One end must be connected to the
condensatedrain connection on the indoor unit and theother
end must be connected to the condensate drain system
located on the outdoor unit in the position indicated in the
photograph (Fig. 17). The condensate is drained from the
condensate drain tank only by the force of gravity. Due to
the restricted space available, the tank is not very high and
therefore the drainage head is somewhat limited. The
drainage line must always feature at least a 3% gradient in
the direction of the flow and must avoid any ascents or
reverse gradients. The condensate drainage line can be
made using any rigid or flexible pipe with a 16 mm minimum
inside diameter.
IMPORTANT: After the condensate drainage line has been
connected to the internal unit it is essential to check that it
functions properly by slowly pouring half a liter of water into
the tray and observing that the resulting flow is regular.
Fig. 17

3.6.2 For Models 8
Eachinternal unitmustbe equippedwithits owncondensa-
te drainage line which on one side depends on the internal
unitis condensate drainage connection and on the other
sidedepends onthebuildingis waterdrainagesystem oron
an open receptacle.
Condensate drainage from the drain tray takes place
exclusivelyduetogravity.Since,forencumbrancereasons,
the tray is not very high, the drain head as a result, is
somewhat limited. The drainage line should always have a
gradientofatleast3%withtheflowandmustbeconstructed
without any upward or counterslopes.
The condensate drainage line may be constructed with any
type of rigid or flexible pipe with an internal diameter of at
least 16 mm.
Ifthe line leads into a sewerage system a seal-trap must be
fitted before entrance into the sewer in order to avoid the
diffusionof badsmellsintotheair-conditionedatmosphere.
The seal-trap must on no account have a 1,5 m difference
in height less than the applianceis lower wire (fig. 18).
If, on the contrary, the condensate drainage line flows into
a receptacle (can etc.) such receptacle must be open in
order to avoid backpressure which would make drainage
difficult and the line end must never get completely
submersed in the water (fig. 19).
IMPORTANT: After the condensate drainage line has been
connected to the internal unit it is essential to check that it
functions properly by slowly pouring half a liter of water into
the tray and observing that the resulting flow is regular.
3.7 Laying and connection of electric lines
IMPORTANT: The applianceis connection to the mains
must be carried out in conformity with the following
instructions and with the norms in force in the place of

4 Startingtheapplianceandtoppingupthecharge
Before turning on the appliance it is essential to make sure
that:
- the input voltage remains within the limits specified in
paragraph2.2"Technicalparticulars".Theappliancemust
not be turned on if the voltage is greater or less than that
specifiedasitcouldundergoseriousdamagenotcovered
by the garantee.
- the cooling charge inserted in the external unit within the
factory has been introduced into the installation. If the
charge has been introduced, the faucets on the external
unitis gas and liquid connections should be open.
- the charge has not leaked due to the appliance being left
off immediately after installation is completed. To carry
outthisoperationitisnecessarytounscrewthecaponthe
service valve which can be found on the external unitis
gas line connection (or on one of the external unitis gas
line connections in the case of the Multisplit appliance)
andseeifthecircuitispressurecorrispondsat leastto the
saturation pressure at atmospheric temperature. If there
is a possibility that a part of the charge has leaked it will

- the air can circulate without difficulty through the internal
(ortheinternalunitsinthe case of Multisplit) and external
units.

enclosed in the Useris Instructions Handbook, turn the
appliance on using the remote control.
Acoupleofminutes afterthe appliancehas beenturnedon,
the compressor is activated and the internal unit starts to
give out cold air.
In the case of hot pump appliances, one must also check
that the appliance starts to pump hot air after switching the
workingmode.One must not forget that once the appliance

has been turned on, hot or warm air is not given off
immediately but after approximately 3 minutes.
If the cooling lines exceed eight metres (in one direction),
introduce20grams of charge into the system for everyextra
metre.
Topping up is carried out in the following manner:
a) Procure a charging station with a cylinder graduated in
grams,agaugecollectorwithtwoflexibles,oneofwhich
must be connected on the gas side of the charging
station and the other must be connected to the service
valveontheexternalunitisgaslineconnection (orinthe
caseof Multisplit, connected totheservicevalve on one
ofthegaslineisconnections). Shoulda chargingstation
not be available, the gauge collector may be connected
to a R410A cylinder placed on a balance. The service
valve is accessible once the cap has been removed.
b) Turn the appliance on and leave it running for a couple
of minutes.
c) Slowly open the charging stationis or cylinderis faucet
until the right quantity of R410A has entered into the
system (the quantity can be observed from the index
scale on the cylinder or from the balance).
IMPORTANT: The air conditioner must be recharged with
R410A ecological refrigerant while the refrigerant is in its
liquid state. Once charged, wait for at least 10” before
starting the compressor to allow the fluid to evaporate.
e) Whenthe operation isfinished,remove the flexiblefrom
the service valve and close the cap firmly one more.
IMPORTANT: Avoid using more cooling liquid than is
absolutely necessary as doing so could have a negative
effect on the applianceis output. Additionally, surplus
charging can be dangerous for the applianceis functioning.
