•
Make sure that a separate power supply circuit is provided for this unit and that all electrical work is carried
out by qualified personnel according to local laws and regulations and this installation manual.
An insufficient power supply capacity or improper electrical construction may lead to electric shocks or fire.
•
Be sure to earth the air conditioner.
Do not earth the unit to a utility pipe, lightning conductor or telephone earth lead. Imperfect earthing may
result in electric shocks or fire.
A high surge current from lightning or other sources may cause damage to the air conditioner.
•
Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in electric shocks or fire.
•
Be sure to switch off the unit before touching any electrical parts.
•
Make sure that all wiring is secured, the specified wires are used, and that there is no strain on the terminal
connections or wires.
Improper connections or securing of wires may result in abnormal heat build-up or fire.
•
When wiring the power supply and connecting the wiring between the indoor and outdoor units, position the
wires so that the EL. COMPO. BOX lid can be securely fastened.
Improper positioning of the EL. COMPO. BOX lid may result in electric shocks, fire or overheating terminals.
•
If refrigerant gas leaks during installation, ventilate the area immediately.
Toxic gas may be produced if the refrigerant gas comes into contact with fire.
•
After completing installation, check for refrigerant gas leakage.
Toxic gas may be produced if the refrigerant gas leaks into the room and comes into contact with a source
of fire, such as a fan heater, stove or cooker.
•
Do not directly touch refrigerant that has leaked from refrigerant pipes or other areas, as there is a danger
of frostbite.
CAUTION
•
Install the BS units, power cord and connecting wires at least 1 meter away from televisions or radios to pre-
vent picture interference and noise.
(Depending on the incoming signal strength, a distance of 1 meter may not be sufficient to eliminate noise.)
•
Remote controller (wireless kit) transmitting distance can be shorter than expected in rooms with electronic
fluorescent lamps (inverter or rapid start types).
Install the BS unit as far away from fluorescent lamps as possible.
•
Make sure to provide for adequate measures in order to prevent that the outdoor unit be used as a shelter
by small animals.
Small animals making contact with electrical parts can cause malfunctions, smoke or fire. Please instruct
the customer to keep the area around the unit clean.
•
Do not install the air conditioner in the following locations:
1.
Where there is a high concentration of mineral oil spray or vapour (e.g. a kitchen).
Plastic parts will deteriorate, parts may fall off and water leakage could result.
2.
Where corrosive gas, such as sulphurous acid gas, is produced.
Corroding of copper pipes or soldered parts may result in refrigerant leakage.
3.
Near machinery emitting electromagnetic radiation.
Electromagnetic radiation may disturb the operation of the control system and result in a malfunction of
the unit.
4.
Where flammable gas may leak, where there is carbon fibre or ignitable dust suspensions in the air, or
where volatile flammables such as paint thinner or gasoline are handled.
Operating the unit in such conditions may result in fire.
5.
Do not use in areas where the air is salty, such as along seacoasts, in factories or other areas with sig-
nificant voltage fluctuations, or in automobiles and watercraft.
Doing so could result in a malfunction.
•
The BS unit is not intended for use in a potentially explosive atmosphere.
