• When wiring the power supply and connecting the remote controller wiring and transmission wiring, position the wires so that the control box lid can be securely fastened.
Improper positioning of the control box lid may result in electric shocks, fire or the terminals overheating.
• 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 BEV units, power cord and connecting wires at least 1 meter away from televisions or radios to
prevent 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 BEV 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.
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 BEV unit is not intended for use in a potentially explosive atmosphere.

2.BEFORE INSTALLATION
• When moving the unit while removing it from the carton box, be sure to lift it by holding on to the
two lifting lugs without exerting any pressure on other parts, especially, the refrigerant piping.
• Be sure to check the type of R410A refrigerant to be used before installing the unit. (Using an incorrect
refrigerant will prevent normal operation of the unit.)
• BEV unit is an electronic expansion valve unit for allowing the indoor unit to be connected to the system for
the VRV system.
• BEV unit may only be connected to the models shown in the table below. Do not attempt connection with
other models.
Indoor unit
Ceiling Suspended Cassette Type
• See the included installation manuals on the VRV outdoor unit and the ceiling suspended cassette type
indoor unit for details.
For the indoor unit connected to the BEV unit, cooling/heating cannot be switched over with the remote controller.
•
• When the cooling/heating free system is connected to the BS unit, a cooling/heating selection right is allowed.
• When the ceiling suspended cassette type indoor unit and BEV unit are used for all indoor units, a separate
“Cool/Heat SELECTOR” is needed to enable the cooling/heating switchover.
2-1PRECAUTIONS
• Do not install or operate the unit in rooms mentioned below.
• Laden with mineral oil, or filled with oil vapor or spray like in kitchens. (Plastic parts may deteriorate
which could eventually cause the unit to fall out of place, or could lead to leaks.)
• Where corrosive gas like sulfurous gas exists. (Copper tubing and brazed spots may corrode, which
could eventually lead to refrigerant leaks.)
• Where exposed to combustible gas and where volatile flammable gas like thinner or gasoline is used.
(Gas in the vicinity of the unit could ignite.)
• Where machines can generate electromagnetic waves. (Control system may malfunction.)
• Where the air contains high levels of salt such as that near the ocean and where voltage fluctuates
greatly such as that in factories.
Also in vehicles or vessels.
• This unit, both indoor and outdoor, is suitable for installation in a commercial and light industrial environment.
