1. Safety precautions

After installation work has been completed, explain the “Safety Precautions,” use,

and maintenance of the unit to the customer according to the information in the

Operation Manual and perform the test run to ensure normal operation. Both the

Installation Manual and Operation Manual must be given to the user for keeping.

These manuals must be passed on to subsequent users.

:Indicates a part which must be grounded.

Warning:

Carefully read the labels afxed to the main unit.

Warning:

• Ask a dealer or an authorized technician to install the unit.

•

The user should never attempt to repair the unit or transfer it to another location.

• For installation work, follow the instructions in the Installation Manual and use

tools and pipe components specically made for use with refrigerant specied

in the outdoor unit installation manual.

•The unit must be installed according to the instructions in order to minimize

the risk of damage from earthquakes, typhoons, or strong winds. An incor-

rectly installed unit may fall down and cause damage or injuries.

•

The unit must be securely installed on a structure that can sustain its weight.

• If the air conditioner is installed in a small room, measures must be taken to

prevent the refrigerant concentration in the room from exceeding the safety

limit in the event of refrigerant leakage. Should the refrigerant leak and cause

the concentration limit to be exceeded, hazards due to lack of oxygen in the

room may result.

•Ventilate the room if refrigerant leaks during operation. If refrigerant comes

into contact with a ame, poisonous gases will be released.

• All electric work must be performed by a qualied technician according to lo-

cal regulations and the instructions given in this manual.

• Use only specied cables for wiring. The wiring connections must be made

securely with no tension applied on the terminal connections. Also, never

splice the cables for wiring (unless otherwise indicated in this document).

Failure to observe these instructions may result in overheating or a re.

•The appliance shall be installed in accordance with national wiring regula-

tions.

•This appliance is not intended for use by persons (including children) with

reduced physical, sensory or mental capabilities, or lack of experience and

knowledge, unless they have been given supervision or instruction concern-

ing use of the appliance by a person responsible for their safety.

•Children should be supervised to ensure that they do not play with the appli-

ance.

• The terminal block cover panel of the unit must be rmly attached.

• If the supply cord is damaged, it must be replaced by the manufacturer, its

service agent or similarly qualied persons in order to avoid a hazard.

•Use only accessories authorized by Mitsubishi Electric and ask a dealer or an

authorized technician to install them.

•The user should never attempt to repair the unit or transfer it to another loca-

tion.

•After installation has been completed, check for refrigerant leaks. If refriger-

ant leaks into the room and comes into contact with the ame of a heater or

portable cooking range, poisonous gases will be released.

•When installing or relocating, or servicing the air conditioner, use only the

specied refrigerant (R410A) to charge the refrigerant lines. Do not mix it with

any other refrigerant and do not allow air to remain in the lines.

If air is mixed with the refrigerant, then it can be the cause of abnormal high pres-

sure in the refrigerant line, and may result in an explosion and other hazards.

The use of any refrigerant other than that specied for the system will cause

mechanical failure or system malfunction or unit breakdown. In the worst

case, this could lead to a serious impediment to securing product safety.

1.1. Before installation (Environment)

Caution:

• Do not use the unit in an unusual environment. If the air conditioner is in-

stalled in areas exposed to steam, volatile oil (including machine oil), or

sulfuric gas, areas exposed to high salt content such as the seaside, the per-

formance can be signicantly reduced and the internal parts can be damaged.

• Do not install the unit where combustible gases may leak, be produced, ow,

or accumulate. If combustible gas accumulates around the unit, re or explo-

sion may result.

•Do not keep food, plants, caged pets, artwork, or precision instruments in the

direct airow of the indoor unit or too close to the unit, as these items can be

damaged by temperature changes or dripping water.

• When the room humidity exceeds 80% or when the drainpipe is clogged, wa-

ter may drip from the indoor unit. Do not install the indoor unit where such

dripping can cause damage.

• When installing the unit in a hospital or communications ofce, be prepared

for noise and electronic interference. Inverters, home appliances, high-fre-

quency medical equipment, and radio communications equipment can cause

the air conditioner to malfunction or breakdown. The air conditioner may

also affect medical equipment, disturbing medical care, and communications

equipment, harming the screen display quality.

1.2. Before installation or relocation

Caution:

• Be extremely careful when transporting the units. Two or more persons are

needed to handle the unit, as it weighs 20 kg or more. Do not grasp the pack-

aging bands. Wear protective gloves as you can injure your hands on the ns

or other parts.

•Be sure to safely dispose of the packaging materials. Packaging materials,

such as nails and other metal or wooden parts may cause stabs or other inju-

ries.

•Thermal insulation of the refrigerant pipe is necessary to prevent condensa-

tion. If the refrigerant pipe is not properly insulated, condensation will be

formed.

•Place thermal insulation on the pipes to prevent condensation. If the drain-

pipe is installed incorrectly, water leakage and damage to the ceiling, oor,

furniture, or other possessions may result.

•Do not clean the air conditioner unit with water. Electric shock may result.

• Tighten all are nuts to specication using a torque wrench. If tightened too

much, the are nut can break after an extended period.

1.3. Before electric work

Caution:

• Be sure to install circuit breakers. If not installed, electric shock may result.

• For the power lines, use standard cables of sufcient capacity. Otherwise, a

short circuit, overheating, or re may result.

•When installing the power lines, do not apply tension to the cables.

• Be sure to ground the unit. If the unit is not properly grounded, electric shock

may result.

•Use circuit breakers (ground fault interrupter, isolating switch (+B fuse), and

molded case circuit breaker) with the specied capacity. If the circuit breaker

capacity is larger than the specied capacity, breakdown or re may result.

1.4. Before starting the test run

Caution:

• Turn on the main power switch more than 12 hours before starting operation.

Starting operation just after turning on the power switch can severely damage

the internal parts.

•Before starting operation, check that all panels, guards and other protective

parts are correctly installed. Rotating, hot, or high voltage parts can cause

injuries.

Note:

The phrase “Wired remote controller” in this installation manual refers only to the PAR-31MAA.

If you need any information for the other remote controller, please refer to either the installation manual or initial setting manual which are

included in these boxes.

• Do not operate the air conditioner without the air lter set in place. If the air

lter is not installed, dust may accumulate and breakdown may result.

•Do not touch any switch with wet hands. Electric shock may result.

• Do not touch the refrigerant pipes with bare hands during operation.

• After stopping operation, be sure to wait at least ve minutes before turning

off the main power switch. Otherwise, water leakage or breakdown may re-

sult.

3.5. Suspension structure (Give site of suspension

strong structure) (Fig. 3-5)

• The ceiling work differs according to the construction of the building. Building

constructors and interior decorators should be consulted for details.

(1) Extent of ceiling removal: The ceiling must be kept completely horizontal and

the ceiling foundation (framework: wooden slats and slat holders) must be rein-

forced in order to protect the ceiling from vibration.

(2) Cut and remove the ceiling foundation.

(3) Reinforce the ends of the ceiling foundation where it has been cut and add ceil-

ing foundation for securing the ends of the ceiling board.

(4) When installing the indoor unit on a slanted ceiling, attach a pillar between the

ceiling and the grille and set so that the unit is installed horizontally.

1Wooden structures

• Use tie beams (single storied houses) or second oor beams (2 story houses) as

reinforcing members.

•Wooden beams for suspending air conditioners must be sturdy and their sides

must be at least 6 cm long if the beams are separated by not more than 90 cm

and their sides must be at least 9 cm long if the beams are separated by as much

as 180 cm. The size of the suspension bolts should be ø10 (3/8"). (The bolts do

not come with the unit.)

2Ferro-concrete structures

Secure the suspension bolts using the method shown, or use steel or wooden

hangers, etc. to install the suspension bolts.

3.6. Unit suspension procedures (Fig. 3-6)

Suspend the main unit as shown in the diagram.

Figures given in parentheses represent the dimensions in case of installing optional

multi function casement.

1. In advance, set the parts onto the suspension bolts in the order of the washers

(with insulation), washers (without insulation) and nuts (double).

•Fit the washer with cushion so that the insulation faces downward.

• In case of using upper washers to suspend the main unit, the lower washers (with

insulation) and nuts (double) are to be set later.

2. Lift the unit to the proper height of the suspension bolts to insert the mounting

plate between washers and then fasten it securely.

3. When the main unit cannot be aligned against the mounting hole on the ceiling,

it is adjustable owing to a slot provided on the mounting plate.

•Make sure that A is performed within 17-22 mm. Damage could result by failing

to adhere to this range. (Fig. 3-7)

Caution:

Use the top half of the box as a protective cover to prevent dust or debris

from getting inside the unit prior to installation of the decorative cover or

when applying ceiling materials.

3.7. Conrming the position of main unit and

tightening the suspension bolts (Fig. 3-8)

• Using the gauge attached to the grille, ensure that the bottom of the main unit is

properly aligned with the opening of the ceiling. Be sure to conrm this, otherwise

condensation may form and drip due to air leakage, etc.

• Conrm that the main unit is horizontally levelled, using a level or a vinyl tube

lled with water.

•After checking the position of the main unit, tighten the nuts of the suspension

bolts securely to fasten the main unit.

•The installation template (top of the package) can be used as a protective sheet

to prevent dust from entering the main unit when the grilles are left unattached for

a while or when the ceiling materials are to be lined after installation of the unit is

nished.

* As for the details of tting, refer to the instructions given on the Installation tem-

plate.

4. Installing the refrigerant piping

4.1. Precautions

For devices that use R410A refrigerant

• Use ester oil, ether oil or alkylbenzene oil (small amount) as the refrigera-

tion oil applied to the ared sections.

• Use C1220 copper phosphorus for copper and copper alloy seamless

pipes, to connect the refrigerant pipes. Use refrigerant pipes with the thick-

nesses specied in the table below. Make sure the insides of the pipes are

clean and do not contain any harmful contaminants such as sulfuric com-

pounds, oxidants, debris, or dust.

Warning:

When installing or relocating, or servicing the air conditioner, use only the

specied refrigerant (R410A) to charge the refrigerant lines. Do not mix it

with any other refrigerant and do not allow air to remain in the lines.

If air is mixed with the refrigerant, then it can be the cause of abnormal high

pressure in the refrigerant line, and may result in an explosion and other haz-

ards.

The use of any refrigerant other than that specied for the system will cause

mechanical failure or system malfunction or unit breakdown. In the worst

case, this could lead to a serious impediment to securing product safety.

Gas pipe [ 12.7 thickness 0.8 mm [ 15.88 thickness 1.0 mm

• Do not use pipes thinner than those specied above.

4.2. Connecting pipes (Fig. 4-1)

• When commercially available copper pipes are used, wrap liquid and gas pipes

with commercially available insulation materials (heat-resistant to 100 °C or

more, thickness of 12 mm or more).

•The indoor parts of the drain pipe should be wrapped with polyethylene foam in-

sulation materials (specic gravity of 0.03, thickness of 9 mm or more).

• Apply thin layer of refrigerant oil to pipe and joint seating surface before tighten-

ing are nut.

• Use 2 wrenches to tighten piping connections.

• Use refrigerant piping insulation provided to insulate indoor unit connections. In-

sulate carefully.

7. Test run

7.1. Before test run

► After completing installation and the wiring and piping of the indoor and

outdoor units, check for refrigerant leakage, looseness in the power sup-

ply or control wiring, wrong polarity, and no disconnection of one phase

in the supply.

► Use a 500-volt megohmmeter to check that the resistance between the

power supply terminals and ground is at least 1.0 MΩ.

► Do not carry out this test on the control wiring (low voltage circuit) termi-

nals.

Warning:

Do not use the air conditioner if the insulation resistance is less than 1.0 MΩ.

7.2. Test run

7.2.1. Using wired remote controller.

■ Make sure to read operation manual before test run. (Especially items to secure safety)

Step 1 Turn on the power.

● Remote controller: The system will go into startup mode, and the remote controller power lamp (green) and “PLEASE WAIT” will blink. While the lamp and message

are blinking, the remote controller cannot be operated. Wait until “PLEASE WAIT” is not displayed before operating the remote controller. After the power is turned on,

“PLEASE WAIT” will be displayed for approximately 2 minutes.

● Indoor controller board: LED 1 will be lit up, LED 2 will be lit up (if the address is 0) or off (if the address is not 0), and LED 3 will blink.

● Outdoor controller board: LED 1 (green) and LED 2 (red) will be lit up. (After the startup mode of the system nishes, LED 2 will be turned off.) If the outdoor controller

board uses a digital display, [- ] and [ -] will be displayed alternately every second.

If the operations do not function correctly after the procedures in step 2 and thereafter are performed, the following causes should be considered and eliminated if they

are found.

Inhaltsverzeichnis

Warnung:

• Bitten Sie Ihren Fachhändler oder einen geprüften Fachtechniker, die Installation

der Anlage vorzunehmen.

• Der Nutzer sollte keinesfalls versuchen, die Anlage selbst zu reparieren oder an

eine andere Stelle zu transferieren.

• Folgen Sie bei der Installation den Anweisungen in der Installationsanweisung, und

verwenden Sie Werkzeuge und Rohrleitungsbestandteile, die ausdrücklich zum

Einsatz desjenigen Kältemittels ausgelegt ist, das in der Aussenanlagen- Installati-

onsanleitung speziziert ist.

• Die Anlage muß entsprechend den Anweisungen installiert werden, um die Gefahr

von Schäden in Folge von Erdbeben, Stürmen oder starkem Windeinuß zu mini-

mieren. Eine falsch installierte Anlage kann herabfallen und dabei Verletzungen

oder Sachschäden verursachen.

• Die Anlage muß sicher an einem Bauteil installiert werden, das das Gewicht der

Anlage tragen kann.

• Wenn die Klimaanlage in einem kleinen Raum installiert wird, müssen Maßnahmen

ergriffen werden, damit die Kältemittelkonzentration auch bei Kältemittelaustritt

den Sicherheitsgrenzwert nicht überschreitet. Sollte Kältemittel austreten und der

Grenzwert der Kältemittelkonzentration überschritten werden, können durch den

Sauerstoffmangel im Raum Gefahren entstehen.

• Lüften Sie den Raum, wenn bei Betrieb Kältemittel austritt. Wenn Kältemittel mit

einer Flamme in Berührung kommt, werden dabei giftige Gase freigesetzt.

• Alle Elektroarbeiten müssen entsprechend den örtlichen Vorschriften und den

Anweisungen in dieser Anleitung von qualizierten Fachelektrikern ausgeführt

werden.

• Verwenden Sie zur Verdrahtung nur die angegebenen Kabel. Die Anschlüsse müssen

fest und sicher ohne Zugbelastung auf den Klemmen vorgenommen werden. Splei-

ßen Sie außerdem niemals die Kabel für die Verdrahtung (außer es wird in diesem

Dokument entsprechend angegeben). Wenn die Kabel falsch angeschlossen oder

installiert sind, kann dies Überhitzung oder einen Brand zur Folge haben.

• Das Gerät muss entsprechend den örtlichen Vorschriften zur Verkabelung eingebaut

werden.

1.1. Vor der Installation (Umgebung)

Vorsicht:

• Setzen Sie die Anlage nicht in unüblichem Umfeld ein. Wenn die Klimaanlage in

Bereichen installiert ist, in denen sie Rauch, austretendem Öl (einschliesslich

Maschinenöl) oder Schwefeldämpfen ausgesetzt ist, oder in Gegenden mit hohem

Salzgehalt, etwa am Meer, kann dies zu erheblichen Leistungsbeeinträchtigungen

und Schäden an den Geräteteilen im Inneren der Anlage zur Folge haben.

• Installieren Sie die Anlage nicht in Bereichen, in denen entzündliche Gase aus-

treten, hergestellt werden, ausströmen oder sich ansammeln können. Wenn sich

entzündliche Gase im Bereich der Anlage ansammeln, kann dies zu einem Brand

oder einer Explosion führen.

• Achten Sie darauf, daß sich weder Nahrungsmittel, Panzen, Kägtiere, Kunst-

gegenstände noch Präzisionsinstrumente im direkten Luftstrom der Innenanlage

oder zu nahe der Anlage benden, da diese durch Temperaturschwankungen oder

• Installieren Sie auf jeden Fall Leistungsschalter. Andernfalls besteht die Gefahr

von Stromschlägen.

•

Verwenden Sie für die Netzleitungen handelsübliche Kabel mit ausreichender Kapazität.

Andernfalls besteht die Gefahr von Kurzschlüssen, Überhitzung oder eines Brandes.

• Achten Sie bei der Installation der Netzleitungen darauf, daß keine Zugspannung

für die Kabel entsteht.

• Die Anlage muß geerdet werden. Wenn die Anlage nicht ordnungsgemäß geerdet

ist, besteht die Gefahr von Stromschlägen.

• Verwenden Sie Leistungsschalter (Erdschlußunterbrecher, Trennschalter (+B-Si-

cherung) und gußgekapselte Leistungsschalter) mit der angegebenen Kapazität.

Wenn die Leistungsschalterkapazität größer ist als vorgeschrieben, kann dies einen

Ausfall der Klimaanlage oder einen Brand zur Folge haben.

1. Sicherheitsvorkehrungen

1.4. Vor dem Testlauf

Vorsicht:

• Schalten Sie den Netzschalter mehr als 12 Stunden vor Betriebsbeginn ein. Ein

Betriebsbeginn unmittelbar nach Einschalten des Netzschalters kann zu schwer-

wiegenden Schäden der Innenteile führen.

• Prüfen Sie vor Betriebsbeginn, ob alle Platten, Sicherungen und weitere Schutz-

vorrichtungen ordnungsgemäß installiert sind. Rotierende, heiße oder unter Hoch-

spannung stehende Bauteile können Verletzungen verursachen.

• Betreiben Sie die Klimaanlage nicht ohne eingesetzten Luftlter. Wenn der Luftlter

nicht installiert ist, besteht die Gefahr, daß sich Schmutz ansammelt und die Anlage

dadurch ausfällt.

• Berühren Sie Schalter nicht mit nassen Händen. Dadurch besteht die Gefahr eines

Stromschlags.

• Berühren Sie die Kältemittelrohre während des Betriebs nicht mit bloßen Hän-

den.

• Nach Beendigung des Betriebs müssen mindestens fünf Minuten verstreichen,

ehe der Hauptschalter ausgeschaltet wird. Andernfalls besteht die Gefahr von

Wasseraustritt oder Ausfall der Anlage.

► Vor dem Einbau der Anlage vergewissern, daß Sie alle Informationen über

„Sicherheitsvorkehrungen“ gelesen haben.

► Vor dem Anschließen dieses Gerätes an das Stromnetz Ihr Stromversorgungs-

unternehmen informieren oder dessen Genehmigung einholen.

Warnung:

Beschreibt Vorkehrungen, die beachtet werden müssen, um den Benutzer vor der

Gefahr von Verletzungen oder tödlichen Unfällen zu bewahren.

Vorsicht:

Beschreibt Vorkehrungen, die beachtet werden müssen, damit an der Anlage keine

Schäden entstehen.

Erläutern Sie dem Kunden nach Abschluß der Installationsarbeiten die „Sicherheitsvorkeh-

rungen“ sowie die Nutzung und Wartung derAnlage entsprechend den Informationen in der

Bedienungsanleitung und führen Sie einen Testlauf durch, um sicherzustellen, daß dieAnlage

ordnungsgemäß funktioniert. Geben Sie dem Benutzer sowohl die Installations- als auch die

Bedienungsanleitung zur Aufbewahrung. Diese Anleitungen sind auch den nachfolgenden

Besitzern der Anlage weiterzugeben.

:Verweist auf einen Teil der Anlage, der geerdet werden muß.

Warnung:

Sorgfältig die auf der Hauptanlage aufgebrachten Aufschriften lesen.

Hinweis:

Der Begriff „Verdrahte Fernbedienung“ in dieser Bedienungsanleitung bezieht sich auf den PAR-31MAA.

• Dieses Gerät darf von Personen (einschließlich Kindern) mit eingeschränkten

physischen, sensorischen oder mentalen Fähigkeiten, bzw. ohne ausreichende

Erfahrung und Wissen, erst nach Einweisung und Anleitung zum Gebrauch des

Geräts durch eine für ihre Sicherheit verantwortliche Person verwendet werden.

• Kinder sollten beaufsichtigt werden, um sicherzustellen, dass sie nicht an den

Geräten herumspielen.

• Die Klemmleistenabdeckung der Anlage muss ordnungsgemäss angebracht

sein.

• Wenn das Netzkabel beschädigt ist, muss er vom Hersteller, dem entsprechenden

Kundendienstmitarbeiter oder einer ähnlich qualizierten Person ersetzt werden,

um Gefahrensituationen zu vermeiden.

• Verwenden Sie nur von Mitsubishi Electric zugelassenes Zubehör, und lassen Sie

dieses durch Ihren Fachhändler oder eine Vertragswerkstatt einbauen.

• Der Benutzer darf niemals versuchen, die Anlage zu reparieren oder an einem

anderen Ort aufzustellen.

• Prüfen Sie die Anlage nach Abschluß der Installation auf Kältemittelaustritt. Wenn

Kältemittel in den Raum gelangt und mit der Flamme einer Heizung oder eines

Gasherds in Berührung kommt, werden dabei giftige Gase freigesetzt.

• Beim Installieren oder Umsetzen oder Warten der Klimaanlage darf nur das angege-

bene Kältemittel (R410A) zur Befüllung der Kältemittelleitungen verwendet werden.

Vermischen Sie es nicht mit anderem Kältemittel und lassen Sie nicht zu, dass Luft

in den Leitungen zurückbleibt.

Wenn sich Luft mit dem Kältemittel vermischt, kann dies zu einem ungewöhnlich

hohen Druck in der Kältemittelleitung führen und eine Explosion oder andere Ge-

fahren verursachen.

Die Verwendung eines anderen als des für das System angegebenen Kältemittels

führt zu mechanischem Versagen, einer Fehlfunktion des Systems oder einer

Beschädigung des Geräts. Im schlimmsten Fall kann sie ein schwerwiegendes

Hindernis für die Aufrechterhaltung der Produktsicherheit darstellen.
