SAFETY PRECAUTIONS1.
Be sure to read this Installation manual thoroughly before installation•
The warnings and precautions indicated in this Installation manual contain impor-•
tant information pertaining to your safety. Be sure to observe them.
After installing the unit, perform a test run to make sure the unit operates normally. •
Then, explain to the customer how to operate and maintain the unit.
Please pass this Installation manual together with the Operating manual to the cus-•
tomer.
Please ask the customer to keep the Operating manual and Installation manual at
hand for future reference during the moving or repair of the main unit.
This mark indicates procedures which, if improperly
WARNING
For installation purposes, be sure to use the parts supplied by the manufacturer or
other prescribed parts.
Using non-specifi ed parts will cause serious accidents such as falling unit, refriger-
ant leakage, water leakage, electric shock, and fi re.
performed, might lead to the death or serious injury of the
user.
.
To in st all a u nit th at us es the R410A refrigerant, use dedicated tools and piping
materials that have been manufactured specifi cally for R410A use.
Because the pressure of the R410A refrigerant is approximately 1.6 times higher
than the R22, failure to use dedicated piping material or improper installation can
cause rupture or injury.
It will also cause serious accidents such as refrigerant leakage, water leakage,
electric shock, and fi re.
Do not introduce any substance other than the prescribed refrigerant into the refrigeration cycle.
If air enters the refrigeration cycle, the pressure in the refrigeration cycle will become abnormally high and cause the piping to rupture.
Be sure to install the unit as prescribed, so that it can withstand earthquakes and
typhoons or other strong winds.
Improper installation can cause the unit to topple or fall, or other accidents
Ensure that the outdoor unit is securely installed at a place that can withstand the
weight of the unit.
Improper installation will cause injuries caused by falling unit.
If there is a refrigerant leakage, make sure that it does not exceed the concentration limit.
If a refrigerant leakage exceeds the concentration limit, it can lead to accidents
such as oxygen starvation.
If a refrigerant leakage occurs during operation, immediately vacate the premises
and thoroughly ventilate the area.
If the refrigerant is exposed to fi re, it will create a hazardous gas.
Electrical work must be performed in accordance with this Installation manual by a
person certifi ed under the national or regional regulations. Be sure to use a dedi-
cated circuit for the unit.
An insuffi cient power supply circuit or improperly performed electrical work can
cause serious accidents such as electric shock or fi re.
For wiring, use the prescribed type of cables, connect them securely, making sure
that there are no external forces of the cables applied to the terminal connections.
Improperly connected or secured cables can cause serious accidents such as
overheating the terminals, electric shock, or fi re.
Do not turn ON the power until all work has been completed.
Turning ON the power before the work is completed can cause serious accidents
such as electric shock or fi re.
After the installation, make sure there is no refrigerant leakage.
If the refrigerant leaks into the room and becomes exposed to a source of fi re such
as a fan heater, stove, or burner, it will create a hazardous gas.
Use a wall hole pipe. Otherwise, it may cause a short circuit.
Do not place the outdoor unit near the handrail of the balcony.
Children may climb onto the outdoor unit, lean over the handrail and fall over.
Use only a specifi ed power cable. Poor connection, poor insulation, and exceeding the
allowable current will lead to electric shock and fi re
Attach the connecting cables securely to the terminal. Or secure it fi rmly with a "wir-
ing suppressor".
Loose connection will lead to malfunction, electric shock, and fi re.
Install a breaker to cut off all AC main current at the same time.
If you do not install a breaker, it may cause electric shock and fi re.
Be sure to install the refrigerant pipe before operating the compressor. If the refrigerant pipe is not installed and you operate the compressor while the valve is open,
air will be sucked into the system and abnormal pressure will occur in the refrigerant cycle. This will damage the unit and cause injuries.
During the pump-down operation, make sure that the compressor is turned off
before you remove the refrigerant piping. Do not remove the connection pipe while
the compressor is in operation with 2-way or 3-way valve open. This may cause
abnormal pressure in the refrigeration cycle that leads to breakage and even injury.
If there is a possibility of touching the fan during maintenance, make sure to turn
OFF the power before implementing the maintenance. Even if operations are
suspended, the fan of outdoor unit sometimes rotates, so if the fan rotates suddenly
while in contact with you may cause serious injury.
This mark indicates procedures which, if improperly

Pay careful attention to the following points :
Since the working pressure is 1.6 times higher than that of R22 models, some of the
piping and installation and service tools are special. (See the table in the SPECIAL
TOOLS FOR R410A section.)
Especially, when replacing a conventional refrigerant (other than R410A) model
with a new refrigerant R410A model, always replace the conventional piping and
fl are nuts with the R410A piping and fl are nuts.
Models that use refrigerant R410A have a different charging port thread diameter
to prevent erroneous charging with R22, R407C and for safety. Therefore, check
beforehand. [The charging port thread diameter for R410A is 1/2 UNF 20 threads
per inch.]
Be more careful than the installation of the refrigerant (other than R410A) models,
not to enter foreign matters (oil, water, etc.) and other refrigerant into the piping.
Also, when storing the piping, securely seal the openings by pinching, taping, etc.
When charging the refrigerant, take into account the slight change in the composition of the gas and liquid phases, and always charge from the liquid phase side
whose composition is stable.

Hoisting method
When hanging the outdoor unit and conveying it to installation location, hang the •
unit with rope by passing through the 4 opening holes on bottom of front and rear
side as shown in fi gure.
Use 2 ropes at least 8m long. If used shorter length, it may cause to damage to the •
unit
.
Use the suffi ciently strong rope to bear the unit’s weight.•
Place the protective board or fi ller cloth at the place where the cabinet may come •
into contact with rope to prevent from damages. Without using them, cabinet may
cause to damage or deform.
During the hanging unit, make sure to keep the unit level to prevent from falling.•
To prevent an unit swing accident or falling down of the unit, do not apply any •
impact to the unit when it is hanging.

SYSTEM CONFIGURATION4.
System confi guration4. 1.
CAUTION
When connecting multiple outdoor units, set the nearest outdoor unit to the indoor •
unit on the refrigerant pipe as the master unit.
When connecting multiple outdoor units, install the outdoor unit with the largest •
nominal system capacity nearest to the indoor unit and on the refrigerant pipe,
followed by those with less nominal system capacities.
Always keep to the limit on the total amount of refrigerant. Exceeding the limit •
on the total amount of refrigerant when charging will lead to malfunction.

PIPE INSTALLATION5.
Brazing5. 1.
CAUTION
If air or different type of refrigerant enters
the refrigeration cycle, the internal pressure in the refrigeration cycle will become
abnormally high and prevent the unit from
exerting its full performance.
Apply nitrogen gas while brazing the
pipes.
Nitrogen gas pressure: 0.02 MPa (= suffi cient pressure to be felt on the back of
your hand or more)
If a pipe is brazed without applying nitrogen gas, it will create an oxidation fi lm.
This can degrade performance or damage the parts in the unit (such as the compressor or valves).
Do not use fl ux to braze pipes. If the fl ux is the chlorine type, it will cause the pipes
to corrode.
In addition, if the fl ux contains fl uoride, it will affect the refrigerant piping system due to
deterioration of refrigerant oil.
For brazing material, use phosphor copper that does not require fl ux.

Opening the knockout hole5. 3. 1.
CAUTION
Be careful to prevent panel deformation or damaged while opening the knockout
hole.
To prevent cutting of the wiring after the knockout hole was opened, remove the
burrs along the edge.
In addition, to prevent rusting, painting the edge with rust preventive paint is recommended.
Removing the pinch pipe5. 3. 2.
WARNING
Remove the pinch pipe only when the internal gas is completely drained as shown
on the below instructions.
If gas still remains inside, the piping may crack if you melt the brazing fi ller metal of
the junction area with a burner.
Before connecting the piping, remove the pinch pipe in accordance with the following
instructions:
Verify that the liquid side , suction gas side and discharge gas side 3-way valves 1)
are closed.

WARNING
Wiring connections must be performed by a qualifi ed person in accordance with
specifi cations.
The rated supply of this product is 50Hz, 400V of 3-phase, 4-wire. Use a voltage
within the range of 342-456V.
Make sure to perform earthing (grounding) work. Improper earthing (grounding) work
can cause electric shocks.
Before connecting the cables, make sure the power supply is OFF.
Be sure to install an earth (ground) leakage breaker. Otherwise, it will cause electric
shock or fi re.
Be sure to install a breaker of the specifi ed capacity. When selecting breaker, please
comply with the laws and the regulations of each country. One breaker must be
installed on the power supply of the outdoor unit. Wrong selection and setup of the
breaker will cause electric shock or fi re.
Do not connect AC power supply to the transmission line terminal board.
Improper wiring can damage the entire system.
Connect the connector cord securely to the terminal.
Faulty installation can cause a fi re.
Do not modify power cable, use extension cable or branch wiring. Improper use may
cause electric shock or fi re by poor connection, insuffi cient insulation or over current.
Make sure to secure the insulation portion of the connector cable with the cord
clamp. A damaged insulation can cause a short circuit.
Never install a power factor improvement condenser. Instead of improving the power factor,
the condenser may overheat.
Before servicing the unit, turn the power supply switch OFF. Then, do not touch electric parts for 10 minutes due to the risk of electric shock.
Always use a separate power supply line protected by a circuit breaker operating on
all cables with a distance between contact of 3 mm for this unit.
Use crimp-type terminals and tighten the terminal screws to the specifi ed torques,
otherwise, abnormal overheating may be produced and possibly cause serious damage inside the unit.
Securely install the electrical box cover on the unit. An improperly installed service
panel can cause serious accidents such as electric shock or fi re through exposure to
dust or water.
If the supply cable is damaged, it must be replaced by the manufacturer, its service
agent or similarly qualifi ed persons in order to avoid a hazard.
If the pipe length between outdoor unit branch kit and outdoor unit branch kit (or (2)
slave unit) is longer than 2 m, or a lower pipe line exists between outdoor units,
rise for gas pipe (Discharge gas pipe and Suction gas pipe) should be arranged
to eliminate oil from entering into and remaining at pipes and the stopped outdoor
unit. However, there is no need to provide a rise on the pipe connecting between
the master unit and the indoor unit even if the length exceeds 2m.

CAUTION
The primary power supply capacity is for the air conditioner itself, and does not include the
concurrent use of other devices.
Connect the power cables in positive phase sequence. If they are connected in
negative phase sequence, an error will be displayed. If there is a missing phase connection, the unit will not operate normally. Do not connect a N phase (neutral phase)
cable to other phases (misconnection). Wrong wiring will lead to parts damage.
Do not use crossover power supply wiring for the outdoor unit.
If the electrical power is inadequate, contact your electric power company.
Install a breaker (Included with earth leakage circuit breaker) in a location that is not
exposed to high temperatures.
If the temperature surrounding the breaker is too high, the amperage at which the
breaker cuts out may decrease.
Use a breaker (Included with earth leakage circuit breaker) that is capable of handling
high frequencies. Because the outdoor unit is inverter controlled, a high-frequency
breaker is necessary to prevent a malfunction of the breaker itself.
When the electrical switchboard is installed outdoors, place it under lock and key so
that it is not easily accessible.
Never bundle the power supply cable and transmission cable, remote control cable
together. Separate these cable by 50 mm or more. Bundling these cables together
will cause miss operation or breakdown.
Always keep to the maximum length of the transmission cable. Exceeding the maximum length may lead to erroneous operation.
The static electricity that is charged to the human body can damage the control PC
board when handling the control PC board for address setting, etc.
Please keep caution to the following points.
Provide the earthing (grounding) of Indoor unit, Outdoor unit and Option equipment.
Cut off the power supply (breaker).
Touch the metal section (such as the unpainted control box section) of the indoor or
outdoor unit for more than 10 seconds. Discharge the static electricity in your body.
Never touch the component terminal or pattern on the PC board.

This mode selects the pattern of the stop function to be operated by the external
input terminal (CN134).
• Batch stop: The stop of all indoor units connected to same refrigerant system

due to input signal coming from CN134.
• Emergency stop: When emergency stop is actuated, the indoor unit does not
accept the operation command from the remote controller. On the other hand,
when the emergency stop is released (no input from CN134), the air conditioner does not return to the original operation until the indoor unit is turned on
by the remote controller.

CAUTION
Use only nitrogen gas.•
Never use refrigerant gas, oxygen, in fl ammable gas or poisonous gas to pressur-

Do not shock during sealing test.•
It can rupture the pipes and cause serious injury.
Do not turn on the power unless all operations are complete.•
Do not block the walls and the ceiling until the sealing test and charging of the •
refrigerant gas have been completed.
After connecting the pipes, perform a sealing test.
Recheck that the spindle of the 3-way valve are closed before performing a sealing
test. (Fig. B)
Pour nitrogen gas through both the liquid pipe and the gas pipe.
Pressurize nitrogen gas to 4.2 MPa to perform the sealing test.
Check all fl are connection areas and brazed areas.
Then, check that the pressure has not decreased.
Compare the pressures after pressurizing and letting it stand for 24 hours, and check
that the pressure did not decreased.
When the outdoor temperature changes 5 °C, the test pressure changes 0.05 *
MPa.
If the pressure has dropped, the pipe joints may be leaking.
If a leakage is found, immediately repair it and perform a sealing test again.
* Decrease the pressure of nitrogen gas before brazing
After completing the sealing test, release the nitrogen gas from both valves.
Release the nitrogen gas slowly.

CAUTION
Do not turn on the power unless all operations are complete.
If the system is not evacuated properly, its performance will drop.
If moisture enter the piping, follow below. (i.e., if doing work during the rainy •
season, if the actual work takes long enough that condensation may form on the
inside of the pipes, if rain might enter the pipes during work, etc.)
After operating the vacuum pump for 2 hours, pressurize to 0.05 MPa (i.e., •
vacuum breakdown) with nitrogen gas, then depressurize down to -100.7kPa
(-755mmHg) for an hour using the vacuum pump (vacuum process).
If the pressure does not reach -100.7kPa (-755mmHg) even after depressurizing •
for at least 2 hours, repeat the vacuum breakdown - vacuum process.
After vacuum process, maintain the vacuum for an hour and make sure the pressure does not rise by monitoring with a vacuum gauge.
Evacuation procedure
Remove the caps of the gas pipe and liquid pipe and check that the valves are 1)
closed.
Remove the charging cap. 2)
Connect a vacuum pump and a pressure gauge to a charging hose and connect 3)
it to the charging port.
Activate the vacuum pump and vacuum the indoor unit and connection piping 4)
until the pressure gauge becomes -100.7kPa (-755mmHg).
Evacuate from both the gas pipe and the liquid pipe.
Continue evacuating the system for 1 hour after the pressure gauge reads 5)
-100.7kPa (-755mmHg).
Remove the charging hose and reinstall the charging cap. 6)

Additional charging8. 3.
CAUTION
Do not turn on the power unless all operations are complete.
After evacuating the system, add refrigerant.
Do not charge the system with a refrigerant other than R410A.
Always keep to the limit on the total amount of refrigerant. Exceeding the limit on
the total amount of refrigerant will lead to malfunction during charging of refrigerant.
Do not reuse recovered refrigerant.
Use an electronic scale to measure the charging amount of refrigerant.
Adding more refrigerant than the specifi ed amount will cause a malfunction.
Charge refrigerant using the liquid pipe.
Adding refrigerant through the gas pipe will cause a malfunction.
Add refrigerant by charging the system with the refrigerant in the liquid state. If
the refrigerant cylinder is equipped with a siphon, it is not necessary to place the
cylinder upright.
Procedure for charging the system with refrigerant8. 3. 1.
Remove the charging cap from the liquid pipe. Use standard refrigeration prac- 1)
tices when charging refrigerant.
Attach a charging hose to the refrigerant cylinder, and connect it to the charging 2)
port.
Add refrigerant by calculating the additional refrigerant volume in accordance with 3)
the calculation formula indicated below.
Remove the charging cap and install the charging hose. 4)
Remove the body caps (suction gas pipe, discharge gas pipe and liquid pipe), 5)
and open the valves.
Close the body caps. 6)
After adding refrigerant, indicate the added charging volume on the unit. 7)
Tighten the body caps and charging caps to the torque values specifi ed in the *
Tabl e A .
To open and close the valves, Use an M4 hexagon wrench for liquid pipe.
Use an M8 hexagon wrench for suction gas pipe and discharge gas pipe.
If you can not charge the specifi ed amount of refrigerant with the above

If the outdoor unit is installed at a level that is higher than the indoor unit, the water •
that has condensed in the 3-way valve of the outdoor unit could travel to the indoor
unit.
Therefore, use putty in the space between the pipe and the insulation to prevent the
entry of water.
Perform test operation for each refrigerant system.
You can set “cooling test run" or “heating test run” with the push button on the outdoor

enthalten wichtige Informationen in Bezug auf Ihre Sicherheit. Beachten Sie diese unbedingt.
Nachdem Sie das Gerät installiert haben, führen Sie einen Probelauf durch, um •
sicher zu stellen, dass das Gerät normal funktioniert. Dann erklären Sie dem Kunden, wie man das Gerät in Betrieb nimmt und wartet.
Übergeben Sie dieses Installationshandbuch bitte zusammen mit der Bedienungs-•
anleitung dem Kunden.
Bitten Sie den Kunden, die Bedienungsanleitung und das Installationshandbuch
so bereitzuhalten, dass zukünftig darauf zurückgegriffen werden kann, wenn das
Hauptgerät bewegt oder repariert wird.
Diese Kennzeichnung weist auf Verfahren hin, die bei
WARNUNG
Verwenden Sie für Installationszwecke ausschließlich Teile, die vom Hersteller
bereitgestellt werden, oder andere vorgeschriebene Teile.
Der Gebrauch nicht spezifi scher Teile verursacht ernste Unfälle, wie zum Beispiel der Herunterfallen des
Geräts, Auslaufen des Kühlmittels, Auslaufen des Wassers, elektrischen Schlag und Feuer.
unsachgemäßer Ausführung zum Tode oder zu schweren
Verletzungen des Benutzers führen könnten.
.
Verwenden Sie zur Installation des Geräts mit dem Kältemittel R410A dafür vorgesehene
Werkzeuge und Rohrmaterialen, die speziell für den Umgang mit R410A gefertigt sind.
Weil der Druck für das Kältemittel R410A ca. 1,6-mal höher liegt als für R22, kann
Verwendung von Rohrmaterial, das nicht für R410A vorgesehen ist, oder eine
unsachgemäße Installation zum Reißen der Rohre oder zu Verletzungen führen.
Es verursacht auch ernsthafte Verletzungen, wie zum Beispiel ein Auslaufen des
Kühlmittels, Auslaufen des Wassers, elektrischen Schock und Feuer.
Führen Sie keine andere Substanz als das vorgeschriebene Kältemittel in den Kältekreislauf ein.
Wenn Luft in den Kältekreislauf gelangt, baut sich ein abnorm hoher Druck auf, der
zum Reißen der Rohrleitungen führt.
Achten Sie darauf das Gerät so wie beschrieben zu installieren, sodass es Erdbeben und Taifune oder andere starke Winde wiederstehen kann.
Eine nicht korrekte Installation kann dazu führen, dass das Gerät umfällt oder herabfällt oder andere Unfälle.
Stellen Sie sicher, dass das Außengerät sicher an einem Ort installiert ist, der das
Gewicht des Geräts tragen kann.
Eine nicht korrekte Installation verursacht Verletzungen durch das Herunterfallen des Geräts.
Wenn ein Kältemittelleck auftritt, muss sichergestellt werden, dass nicht der zulässige Konzentrations-Grenzwert überschritten wird.
Wenn bei einem Kältemittelleck der zulässige Konzentrations-Grenzwert überschritten wird, kann dies zu Unfällen, wie z.B. Sauerstoffmangel, führen.
Wenn es während der Arbeiten zu einem Kältemittelleck kommt, verlassen Sie die
Räumlichkeiten sofort und lüften Sie den Bereich gründlich.
Wenn das Kältemittel Feuer ausgesetzt wird entsteht ein gefährliches Gas.
Elektrische Arbeiten müssen in Übereinstimmung mit diesem Installationshandbuch von einer Person ausgeführt werden, die nach nationalen oder regionalen Bestimmungen hierfür
zugelassen ist. Achten Sie darauf, einen eigenen Stromkreis für das Gerät zu verwenden.
Ein unzureichender Stromversorgungskreis oder unsachgemäß ausgeführte Elektroarbeiten können schwere Unfälle, wie z.B. Stromschlag oder Brand, verursachen.
Verwenden Sie für die Verdrahtung die vorgeschriebenen Kabeltypen, schließen
Sie diese fest an und stellen Sie sicher, dass keine Außenkräfte der Kabel auf die
Klemmenanschlüsse einwirken.
Unsachgemäß angeschlossene oder befestigte Kabel können schwere Unfälle, wie
z.B. Überhitzung der Klemmen, Stromschlag oder Brand, verursachen.
Schalten Sie die Stromversorgung nicht vor dem Abschluss sämtlicher Arbeiten ein.
Das Einschalten der Stromversorgung vor dem Abschluss der Arbeiten kann
schwere Unfälle, wie z. B. Stromschlag oder Brand, verursachen.
Achten Sie nach der Installation darauf, dass es keine Kältemittelleckage gibt.
Wenn das Kältemittel in den Raum leckt und einer Feuerquelle ausgesetzt wird, wie
zum Beispiel einer Lüfterheizung, Ofen oder Brenner, entsteht ein gefährliches Gas.
Verwenden Sie ein Rohr in der Wandöffnung. Ansonsten könnte ein Kurzschluss verursacht werden.
Stellen Sie das Außengerät nicht in Nähe des Balkongeländers auf.
Es könnte passieren, dass Kinder auf das Außengerät klettern und sich über das
Geländer lehnen und herunterfallen.
Verwenden Sie nur ein spezielles Netzkabel. Eine schlechte Verbindung, schlechte Isolierung
und das Überschreiten der zulässigen Stromstärke führt zu elektrischem Schock und Feuer.
Bringen Sie die verbindenden Kabel fest an den Klemmen an. Oder befestigen Sie
sicher mit einem „Kabelentstörer“.
Lose Verbindungen führen zu Fehlfunktionen, elektrischem Schlag oder Brand.
Installieren Sie einen Stromschutzschalter, um den gesamten Wechselstrom gleichzeitig abzuschalten.
Wenn Sie keinen Stromschutzschalter installieren, kann es zu einem elektrischen
Schlag oder Brand kommen.
Achten Sie darauf das Kältemittelrohr zu installieren, bevor Sie den Kompressor in
Betrieb nehmen. Wenn das Kältemittelrohr nicht installiert ist und Sie den Kompressor in betrieb nehmen, während das Ventil geöffnet ist, wird Luft in das System
gesaugt und es entsteht ein anormaler Druck im Kältemittelkreislauf. Dies schädigt
das Gerät und verursacht Verletzungen.
Achten Sie während des Pump-Down-Betriebs darauf, dass der Kompressor
ausgeschaltet wurde, bevor Sie die Kältemittelleitung entfernen. Entfernen Sie nicht
das Verbindungsrohr, während der Kompressor in Betrieb ist, während das 2-Wege
oder 3-Wege-Ventil geöffnet ist. Dies verursacht einen anormalen Druck im Kältemittelkreislauf, der zu Bruchstellen und sogar zu Verletzungen führt.
Wenn es sein kann, dass der Lüfter während der Wartung berührt wird, achten Sie
darauf, den Strom AUS zu stellen, bevor Sie die Wartung durchführen. Selbst wenn
der Betrieb unterbrochen wird kann es sein, dass sich der Lüfter des Außengeräts
dreht, also kann es sein, dass es zu Verletzungen kommt, wenn der Lüfter sich
plötzlich dreht, wenn Sie ihn berühren.
Diese Kennzeichnung weist auf Verfahren hin, die bei un-

ÜBER DAS GERÄT2.
Vorsichtsmaßnahmen beim Gebrauch des R410A Kühlmittels2. 1.
Passen Sie bei den folgenden Punkten besonders gut auf:
Da der Arbeitsdruck 1,6 mal höher ist als der des R22-Modells, sind einige der
Leitungen und die Installation sowie Wartungswerkzeuge speziell. (Siehe Tabelle im
Abschnitt SPEZIALWERKZEUGE FÜR R410A.)
Besonders wenn Sie ein konventionelles Kältemittelmodell (nicht R410A) mit einem
neuen Kältemittelmodell R410A austauschen, ersetzen Sie immer die konventionellen Leitungenund Bördelmuttern mit der R410A Leitung und Bördelmuttern.
Modelle, die das Kältemittel R410A verwenden, haben eine anderen Gewindedurchmesser der Einfüllöffnung, um ein irrtümliches Aufl aden mit R22, R407C und
zur Sicherheit zur verhindern. Daher überprüfen Sie dies vorab. [Der Gewindedurchmesser der Einfüllöffnung für R410A ist 1/2 UNF 20 Gänge pro Zoll.]
Seien Sie noch vorsichtiger als bei der Installation der Kältemittelmodelle (andere
als R410A), damit kein Fremdmaterial (Öl, Wasser usw.) und anderes Kältemittel in
die Leitungen eindringt. Auch bei der Lagerung von Leitungen sind deren Öffnungen durch Zusammendrücken, mit Klebeband etc. dicht zu verschließen.
Wenn Sie das Kältemittel einfüllen, berücksichtigen Sie die leichte Änderung i der
Zusammensetzung der Gas- und Flüssigkeitsphasen und und befüllen Sie immer
von der Flüssigkeitsphasenseite, deren Zusammensetzung stabil ist.
Spezialwerkzeuge für R410A2. 2.
Werkzeugname Geänderter Inhalt für das R22-Werkzeug
Der Druck ist riesig und kann nicht mit einem konventionellen
Messgerät (R22) gemessen werden. Der Durchmesser aller
Manometeranschlussgarnitur
Füllschlauch
Anschlüsse wurde geändert, um zu verhindern, dass es versehentlich zu einer Vermischung mit anderen Kältemitteln kommt.
Es wird empfohlen eine Manometeranschlussgarnitur mit einem
Hochdruckanzeigebereich von -0,1 bis 5,3 MPa und einem Niederdruckanzeigebereich von -0,1 bis 3,8 MPa zu verwenden.
Zur Erhöhung der Druckfestigkeit wurden Schlauchmaterial
und Rohrmaß geändert.

VORSICHT
Wählen Sie einen Installationsort aus, indem Sie folgende Vorsichtsmaßnahmen beachten:
Installieren Sie die Gerätestufe. (Innerhalb von 3 Grad)
Installieren Sie dieses Gerät an einem Ort mit guter Belüftung.
Wenn das gerät an einem Ort installiert werden muss, der in Reichweite des
allgemeinen Publikums liegt, installieren Sie, wenn nötig, einen Schutzzaun oder
Ähnliches, um den Zugang zu verhindern.
Installieren Sie das Gerät in einem Bereich, der Ihre Nachbarn nicht stört, da sie vom Luftstrom, der aus dem Ausgang kommt, dem Geräusch oder der Vibration betroffen sein könnten.
Wenn es in der Nähe Ihrer Nachbarn installiert werden muss, sichern Sie sich ihre Zustimmung.
Wenn das Gerät in einer kalten Region installiert wird, in der es zu Schneeansammlungen, Schneefall oder Frost kommt, treffen Sie die entsprechenden Maßnahmen,
um es vor diesen Elementen zu schützen.
Um einen stabilen Betrieb sicher zu stellen, installieren Sie Ein- und Auslasskanäle.
Installieren Sie das Gerät in einem Bereich, der keine Probleme verursacht, selbst
wenn das Abwasser vom Gerät abgelassen wird. Ansonsten stellen Sie sicher, dass
das abgelassene Wasser keine Menschen oder Objekte beeinträchtigt.
Installieren Sie das Gerät in einem Bereich, der keine Heizquellen, Dämpfe hat oder an
dem es kein Risiko für das Auslaufen entzündlicher Gase in der Nachbarschaft gibt.
Installieren Sie das Gerät in einem Bereich, der nicht in der Nähe von Abgas- oder
Entlüftungsanschlüssen liegt, die Dampf, Ruß, Staub oder Rückstände ausstoßen.
Installieren Sie Innengerät, Außengerät, Netzkabel, Übertragungskabel und Fernbe-
dienungskabel mindestens in 1 Meter Entfernung zu Fernsehern oder Radios.
Dies dient der Vermeidung von TV-Empfangsstörungen und Radio-Rauschen. (Unter
bestimmten Signalbedingungen kann es auch dann zu einem verrauschten Empfang
kommen, wenn die Installation weiter als 1 Meter entfernt erfolgt.)
Halten Sie die Länge der Leitungen der Innen- und Außengeräte innerhalb des zulässigen Bereichs.
Zu Wartungszwecken graben Sie die Leitungen nicht ein.
Ablassvorgang3. 2.
Das Abwasser wird unten am Gerät abgelassen. Bauen Sie einen Abfl ussgraben •
um die Grundfl äche herum und lassen Sie das Abwasser richtig ab.
Wenn Sie das Gerät auf einem Dach installieren, führen Sie korrekt eine Bodenab-•
dichtung durch.
Ablassvorgang:
Während des Betriebs kann sich das Abwasser von der Grundfl äche des Außengeräts bilden.•
Führen Sie wenn nötig einen Ablassvorgang durch.
Wenn Sie verhindern möchten, dass das Abwasser an der Abgrenzung ausläuft, •
bauen Sie einen Graben für das Abwasser, wie in der Abbildung gezeigt wird.
Wenn nötig, stellen Sie eine Ablaufwanne bereit.•

Installationsmaße3. 3.
VORSICHT
Wenn Sie das Außengerät installieren, achten Sie auf folgende Punkte.
Bieten Sie ausreichend Installationsraum, wie zum Beispiel Transportweg, Wartungsraum, Belüftungsraum, Kühlmittelleitungsraum und Durchgänge.
Achten Sie auf die Spezifi kationen des Installationsraums, wie in der Abbildung
gezeigt. Wenn das Gerät nicht gemäß der Spezifi kationen installiert wurde, kann es
zum Kurzschluss oder schlechter Leistung kommen. Das Gerät kann aufgrund des
Hochdruckschutzes anfällig dafür sein, in den Nicht-Betrieb zu verfallen.
Stellen Sie keine Hindernisse in die Auslassrichtung des Luftstroms. Wenn es ein
Hindernis in der Auslassrichtung gibt, installieren Sie einen Auslasskanal.
