2 English• Install the air conditioner, power supply wiring, remote control-ler wiring and transmission wiring at least 1 meter away fromtelevisions or radios to prevent image interference or noise.(Depending on the radio waves, a distance of 1 meter maynot be sufficient to eliminate the noise.)• Install the indoor unit as far as possible from fluorescent lamps.If a wireless remote controller kit is installed, the transmissiondistance may be shorter in a room where an electronic lightingtype (inverter or rapid start type) fluorescent lamp is installed.• Do not install the air conditioner in places such as the following:1. Where there is mist of oil, oil spray or vapour for examplea kitchen.Resin parts may deteriorate, and cause them to fall out orwater to leak.2. Where corrosive gas, such as sulfurous acid gas, is produced.Corrosion of copper pipings or brazed parts may causethe refrigerant to leak.3. Where there is machinery which emits electromagnetic waves.Electromagnetic waves may disturb the control system,and cause malfunction of the equipment.4. Where flammable gases may leak, where carbon fibre orignitable dust is suspended in the air or where volatileflammables, such as thinner or gasoline, are handled.If the gas should leak and remained around the air condi-tioner, it may cause ignition.• The air conditioner is not intended for use in a potentiallyexplosive atmosphere.2. BEFORE INSTALLATION• When moving the unit while removing it from the cartonbox, be sure to lift it by holding on to the four lifting lugswithout exerting any pressure on other parts, especially,the refrigerant piping, drain piping, and other resin parts.• Be sure to check the type of R410A refrigerant to be usedbefore installing the unit. (Using an incorrect refrigerant willprevent normal operation of the unit.)• The accessories needed for installation must be retained in your cus-tody until the installation work is completed. Do not discard them!• Decide upon a line of transport.• Leave the unit inside its packaging while moving, until reach-ing the installation site. Where unpacking is unavoidable, usea sling of soft material or protective plates together with arope when lifting, to avoid damage or scratches to the unit.• When selecting installation site, refer to the paper pattern.• For the installation of an outdoor unit, refer to the installationmanual attached to the outdoor unit.• Do not install or operate the unit in rooms mentioned below.• Laden with mineral oil, or filled with oil vapor or spraylike in kitchens. (Plastic parts may deteriorate whichcould eventually cause the unit to fall out of place, orcould lead to leaks.)• Where corrosive gas like sulfurous gas exists. (Cop-per tubing and brazed spots may corrode, whichcould eventually lead to refrigerant leaks.)• Where exposed to combustible gases and where vol-atile flammable gas like thinner or gasoline is used.(Gas in the vicinity of the unit could ignite.)• Where machines can generate electromagneticwaves. (Control system may malfunction.)• Where the air contains high levels of salt such as thatnear the ocean and where voltage fluctuates greatlysuch as that in factories.Also in vehicles or vessels.• This unit, both indoor and outdoor, is suitable for installationin a commercial and light industrial environment.If installed as a household appliance it could cause electro-magnetic interference.2-1 PRECAUTIONS• Be sure to read this manual before installing the indoor unit.• Entrust installation to the place of purchase or a qualified ser-viceman. Improper installation could lead to leaks and, inworse cases, electric shock of fire.• Use only parts provided with the unit or parts satisfyingrequired specifications. Unspecified parts could cause theunit to fall out of place, or could lead to leaks and, in worsecases, electric shock or fire.2-2 ACCESSORIESCheck the following accessories are included with yourunit.2-3 OPTIONAL ACCESSORIES• These are two types of remote controllers: wired and wire-less.
