2 English• Make certain that all electrical work is carried out by qualified personnel according to the applicable leg-islation (note 1) and this installation manual, using a separate circuit.In addition, even if the wiring is short, make sure to use a wiring that has sufficient length and neverconnect additional wiring to make the length sufficient.Insufficient capacity of the power supply circuit or improper electrical construction may lead to electricshocks or a fire.(note 1) applicable legislation means “All international, national and local directives, laws, regulationsand/or codes which are relevant and applicable for a certain product or domain”.• Earth the air conditioner.Do not connect the earth wiring to gas or water piping, lightning conductor or telephone earth wiring.Incomplete earthing may cause electric shocks or a fire.A high surge current from lightning or other sources may cause damage to the air conditioner.• Be sure to install an earth leakage circuit breaker.Failure to do so may cause electric shocks and a fire.• Disconnect the power supply before touching the electric components.If you touch the live part, you may get an electric shocks.• Make sure that all wiring is secure, using the specified wiring and ensuring that external forces do not acton the terminal connections or wiring.Incomplete connection or fixing may cause an overheat or a fire.• Wiring for power supply and between the indoor and outdoor units must be properly laid and formed, andthe control box cover must be firmly fastened so that the wiring may not push up the structural parts suchas the cover.If the cover is improperly fastened, it may cause electric shock or fire.• If refrigerant gas leaks during installation work, ventilate the area immediately.Toxic gas may be produced if refrigerant gas comes into contact with a fire.• After completing the installation work, check to make sure that there is no leakage of refrigerant gas.Toxic gas may be produced if refrigerant gas leaks into the room and comes into contact with a source ofa fire, such as a fan heater, stove or cooker.• Never directly touch any accidental leaking refrigerant. This could result in severe wounds caused byfrostbite.CAUTION• Install drain piping according to this installation manual to ensure good drainage, and insulate the pipingto prevent condensation.Improper drain piping may cause water leakage, make the furniture get wet.• Install the BS units, power supply wiring, remote controller wiring and transmission wiring at least 1 maway from televisions or radios to prevent image interference or noise.(Depending on the radio waves, a distance of 1 m may not be sufficient to eliminate the noise.)• Install the BS unit as far as possible from fluorescent lamps.If a wireless remote controller kit is installed, the transmission distance may be shorter in a room wherean electronic lighting type (inverter or rapid start type) fluorescent lamp is installed.• Make sure to provide for adequate measures in order to prevent that the outdoor unit be used as a shel-ter by small animals.Small animals making contact with electrical parts can cause malfunctions, smoke or fire. Please instructthe customer to keep the area around the unit clean.• Do not install the air conditioner in places such as the following:1. The outside building, rain water permeates in BS unit and it becomes a cause of an electric shock.2. Where there is mist of oil, oil spray or vapour for example a kitchen.Resin parts may deteriorate, and cause them to fall out or water to leak.3. Where corrosive gas, such as sulfurous acid gas, is produced.Corrosion of copper pipings or brazed parts may cause the refrigerant to leak.4. Where there is machinery which emits electromagnetic waves.Electromagnetic waves may disturb the control system, and cause malfunction of the equipment.
