1. Safety precautions

Before installing the unit, make sure you read all the "Safety precau-

tions".

Please report to your supply authority or obtain their consent before

connecting this equipment to the power suppmysystem.

Warning:

Describes precautions that must be observed to prevent danger of injury or

death to the user.

Z_ Caution:

Describes precautions that must be observed to prevent damage to the unit.

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 which must be

part grounded.

Warning:

Carefully read the labels affixed to the main unit.

Warning:

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

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

tools and pipe components specifically made for use with refrigerant specified

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.

o Ventilate the room if refrigerant leaks during operation, if refrigerant comes

into contact with a flame, poisonous gases will be released.

, All electric work must be performed by a qualified technician according to

local regulations and the instructions given in this manual.

, Use only specified cables for wiring.

, The terminal block cover panel of the unit must be firmly attached.

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

an authorized technician to instammthem.

, The user shoumd never attempt to repair the unit or transfer it to another moca-

tion.

o After installation has been completed, check for refrigerant leaks, if refriger-

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

portabme cooking range, poisonous gases will be released.

1.1. Before installation (Environment)

Caution:

,, Do not use the unit in an unusuam environment, if the air conditioner is in-

stalmedin areas exposed to steam, vomatimeoim(incmuding machine oim),or sulfuric

gas, areas exposed to high salt content such as the seaside, the performance

can be significantmy reduced and the internam parts can be damaged.

,, Do not install the unit where combustible gases may leak, be produced, flow,

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

sion may resumt.

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

direct airflow of the indoor unit or too close to the unit as these items can be

damaged by temperature changes or dripping water.

o When the room humidity exceeds 80% or when the drainpipe is cmogged, 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 office, 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 equip-

ment, harming the screen display quality.

1.2. Before installation or relocation

Caution:

,, Be extremely carefum when transporting the units.Two or mote persons are

needed to handle the unit as it weighs 20 kg, 44 Ibe or more. Do not grasp the

packaging bands. Wear protective gloves as you can injure your hands on

the fins or other parts.

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

such as naimsand other metam or wooden parts may cause stabs or other

injuries.

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

tion. if the refrigerant pipe isnot properly insulated, condensation will beformed.

o Place thermal insulation on the pipes to prevent condensation, if the drain-

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

furniture, or other possessions may result.

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

, Tighten all flare nuts to specification using a torque wrench. If tightened too

much, the flare 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 sufficient capacity. Otherwise, a

short circuit, overheating, or fire may result.

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

o 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 specified capacity. If the circuit breaker

capacity is larger than the specified capacity, breakdown or fire 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 dam-

age 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.

o Do not operate the air conditioner without the air filter set in place, if the air

filter 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 five minutes before turning off

the main power switch. Otherwise, water meakage or breakdown may resumt.

buidor o a un tecnico autorizado que se los instale.

o El usuario nunca debe intentar reparar la unidad o moverla de sitio.

o Tras haber realizado la instalaci6n, compruebe si hay fugas de refrigerante. Si

en caso de fuga el refrigerante entra en contacto con las llamas de un calen-

tador o de un equipo de cocina port&til, se desprenderan gases nocivos.

1.1. Cuestiones previas a la instalaci6n (Ambiente)

z_ Cuidado:

, No utilice maunidad en un ambiente enrareeido. Si instamael aire acondiciona-

do en zireas expuestas amvapor, aceite esenciam (incmuyendo el aceite para

maquinas), o humo suffurico, areas con alto contenido en samcomo pmayas,el

rendimiento puede verse reducido significativamente y maspiezas internas

pueden daiiarse.

, No instame la unidad donde se puedan verter, producir, circular o acumumar

gases inflamabmes. Sise acumula gas inflamabme en zonas pr6ximas ama uni-

dad, se podria producir un incendio o una expmosi6n.

, No comoque amimentos, pmantas,animames, obras de arte o instrumentos de pre-

cisi6n en masamida de aire directa de maunidad exterior o demasiado cerca de

ella, ya que moscambios de temperatura o el agua que gotea podrian da_arlos.

o Cuando la humedad de la habitacion supera el 80%, o cuando el tubo de

drenaje este obstruido, puede gotear agua de la unidad interior. No instale la

unidad interior en lugares donde el goteo pueda causar dahos.

o Si instala la unidad en un hospital o en un centro de comunicaciones, recuer-

de que la unidad produce ruidos e interferencias eleetronicas. Los conmuta-

dotes, aparatos dom_sticos, equipos m_dicos de alta frecuencia y las comu-

nicaciones de radio pueden provocar un real funcionamiento o la averia del

equipo de aire acondicionado. El equipo de aire aeondicionado tambien puede

afectar los equipos m_dicos e interrumpir los cuidados m_dicos, asi como

los equipos de comunicaci6n y da_ar la calidad de la pantalla.

1.2. Antes de la instalaci6n o reubicaci6n

/_ Cuidado:

, Tenga mucho cuidado cuando mueva las unidades. Se neeesitan dos o m&s

personas para Hevar la unidad ya que pesa 20 kg, 44 robso mas. No masujete

por mas bandas de embamaje. Utimice guantes protectores ya que se podria

mesionar con las ametas u otras partes.

, Guarde mosembalajes en un lugar seguro. Los materiales de embalaje, eomo

clavos y otras piezas de metal o de madera pueden producir pinchazos y

otras lesiones.

, El tubo de refrigerante debe estar aislado termicamente para evitar la con-

densacion. Si el tubo de refrigerante no se aisla correctamente, se formarzi

condensaci6n.

o Sitt_e material aislante termico en las tuberias para evitar la condensaci6n. Si

el tubo de drenaje no se instala correctamente, se puede producir un escape

de agua o daSos en el techo, suelo, muebles u otros objetos.

o No limpie con agua el equipo de aire acondicionado. Puede sufrir una des-

carga el_ctrica.

o Apriete las tuercas de aboeardado a los niveles especificados mediante una

llave dinamom_trica. Si las aprieta demasiado, se pueden romper al cabo de

un tiempo.

1.3. Antes de la instalaci6n el_ctrica

/_ Cuidado:

, Asegt_rese de instalar disyuntores. Si no se instalan, se podrian producir

descargas eieetricas.

, Use cables est&ndar de suficiente eapacidad para las lineas electricas. Si no

Io hace asi, se podria producir un cortocircuito, un sobrecalentamiento o un

incendio.

o Cuando instale las lineas el_ctricas, los cables no deben tenet corriente.

o Asegurese de instalar una toma de tierra. Si la unidad no est& bien conectada

a la linea de tierra, se puede producir una descarga el_etrica.

o Utilice disyuntores (interruptor de falta de tierra, interrupter aislante (+fusi-

potencia del interruptor es mayor que la especificada, puede ocurrir un in-

cendio o una averia.

1.4. Antes de realizar las pruebas de funcionamiento

,/fk Cuidado:

, Coneete la corriente al menos 12 horas antes de que empieee a funcionar el

equipo. Si se acciona inmediatamente despues de habedo coneetado a la

corriente, pueden producirse da5os graves en las piezas internas.

, Antes de que comience a funcionar el equipo, compruebe que todos los pa-

neles y proteetores estan instalados correctamente. Las piezas giratorias,

calientes o de alto voltaje pueden provocar lesiones.

, No haga funcionar el equipo de aire acondicionado sin el filtro de aire insta-

lado. Si el filtro de aire no esta colocado, se puede acumular el polvo y se

puede averiar el equipo.

o No toque ningun interruptor con las manos mojadas. Puede sufrir una des-

carga el_ctrica.

o No toque la tuberia del refrigerante sin guantes mientras durante el funcio-

namiento.

o Una vez deje de funcionar el aparato, espere cinco minutos antes de apagar

el interrupter principal. De Io contrario, se puede producir un goteo de agua

o una averia.

4.1.1. Para aparatos con refrigerante R410A

, Utilice aceite de _ster, de _ter o alquilobenceno (en pequehas cantidades)

para recubrir las secciones abocardadas.

, Utilice tubes de cobre fosforoso del ripe C1220 y tubes de aleaci6n de cobre

sin costuras para cenectar los tubes del refrigerante. Utilice tuberias para

refrigerante del grosor especificado en la tabla siguiente. Asegurese de que

el interior de las tuberias est_ limpio y que no contienen ningun contaminan-

te nocivo come compuestos sulfuricos, oxidantes, restos o polvo.
