1. SAFETY PRECAUTIONS
Be sure to follow this “SAFETY PRECAUTIONS”.
This product comes under the term “appliances not accessible to the general public”.
This is a class A product. In a domestic environment this product may cause radio interference in which
case the user may be required to take adequate measures.
This manual classies the precautions into WARNINGS and CAUTIONS.
Be sure to follow all the precautions below: They are all important for ensuring safety.
WARNING .........
CAUTION .........
WARNING
• Ask your local dealer or qualied personnel to carry out installation work.
Improper installation may result in water leakage, electric shocks or a re.
• Perform installation work in accordance with this installation manual.
Improper installation may result in water leakage, electric shocks or a re.
• Consult your local dealer regarding what to do in case of refrigerant leakage.
When the air conditioner is installed in a small room, it is necessary to take proper measures so that the
amount of any leaked refrigerant does not exceed the concentration limit in the event of a leakage.
Otherwise, this may lead to an accident due to oxygen deciency.
• Be sure to use only the specied parts and accessories for installation work.
Failure to use the specied parts may result in the air conditioner falling down, water leakage, electric
shocks, a re, etc.
• Install the air conditioner on a foundation that can withstand its mass.
Insufcient strength may result in the air conditioner falling down and causing injury.
In addition, it may lead to vibration of indoor units and cause unpleasant chattering noise.
• Carry out the specied installation work in consideration of strong winds, typhoons, or earthquakes.
Improper installation may result in an accident such as air conditioner falling.
Indicates a potentially hazardous situation which, if not avoided, could result in death
or serious injury.
Indicates a potentially hazardous situation which, if not avoided, may result in minor
or moderate injury.
It may also be used to alert against unsafe practices.
English 1
• Make certain that all electrical work is carried out by qualied 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 sufcient length and never
connect additional wiring to make the length sufcient.
Insufcient capacity of the power supply circuit or improper electrical construction may lead to electric
shocks or a re.
(note 1) applicable legislation means “All international, national and local directives, laws, regulations
and/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 re.
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 re.
• 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 specied wiring and ensuring that external forces do not act
on the terminal connections or wiring.
Incomplete connection or xing may cause an overheat or a re.
• Wiring for power supply and between the indoor and outdoor units must be properly laid and formed, and
the control box cover must be rmly fastened so that the wiring may not push up the structural parts such
as the cover.
If the cover is improperly fastened, it may cause electric shock or re.
• If refrigerant gas leaks during installation work, ventilate the area immediately.
Toxic gas may be produced if refrigerant gas comes into contact with a re.
• 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 of
a re, such as a fan heater, stove or cooker.
• Never directly touch any accidental leaking refrigerant. This could result in severe wounds caused by
frostbite.
CAUTION
Install drain piping according to this installation manual to ensure good drainage, and insulate the piping
•
to 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 m
away from televisions or radios to prevent image interference or noise.
(Depending on the radio waves, a distance of 1 m may not be sufcient to eliminate the noise.)
• Install the BS unit as far as possible from uorescent lamps.
If a wireless remote controller kit is installed, the transmission distance may be shorter in a room where
an electronic lighting type (inverter or rapid start type) uorescent 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 re. Please instruct
the 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.
2 English
5. Where ammable gases may leak, where carbon bre or ignitable dust is suspended in the air or
where volatile ammables, such as thinner or gasoline, are handled.
If the gas should leak and remained around the air conditioner, it may cause ignition.
6. Do not use in areas where the air is salty, such as along seacoasts, in factories or other areas with
signicant voltage uctuations, or in automobiles and watercraft.
Doing so could result in a malfunction.
7. Where a wind may ow, the surface of BS unit body dews, and it becomes a cause of a leak.
• The BS unit is not intended for use in a potentially explosive atmosphere.
2. BEFORE INSTALLATION
2-1 Precautions
• Be sure to verify in advance that the refrigerant used in installation work is R410A.
The unit will not operate correctly with a different type of refrigerant.
• When moving the unit during or after unpacking, hold it using the 4 hanging brackets and avoid
subjecting other parts, particularly refrigerant pipes and the control box, to force.
• For more information about installation of outdoor and indoor units, refer to the installation manual
that came with each unit.
2-2 Accessories
• Verify that the following accessories have been included in the packaging.
Important
Do not throw away any accessories that may be needed in installation work until installation is complete.
