Daikin FAQ71CVEB Installation Manual page 3

• Install the air conditioner on a foundation strong enough to withstand the weight of the unit.
If a foundation does not have sufficient strength, the equipment may fall and cause injury.
• Carry out the required installation work in consideration of strong winds, typhoons or earthquakes.
If the installation work is not properly carried out, the unit may fall down and cause accidents.
• The electrical work must be carried out by the qualified electrician in accordance with the local laws and
regulations and this installation manual. Make sure to provide a dedicated power supply circuit and never
connect additional wiring to the existing circuit.
An insufficient power supply capacity or improper electrical work 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. Touching a live part may result in elec-
tric shock.
• For wiring, use the specified wires and connect and fasten them firmly so that no external force from the
wires may be applied to the terminal connections.
If the wires are not firmly connected and fastened, it may cause heating, fire or the like.
• Wiring for power supply and between the indoor and outdoor units must be properly laid and formed, and
the control box lid must be firmly fastened so that the wiring may not push up the structural parts such as
the lid.
If the lid is improperly fastened, it may cause electric shock or fire.
• If refrigerant gas leaks during installation, ventilate the area immediately.
Toxic gas may be produced if the refrigerant 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
• Carry out drain piping properly following this installation manual and insulate the pipe to prevent conden-
sation.
Improper drain piping may result in indoor water leakage and property damage.
• Install the indoor and outdoor 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.)
• Install the indoor unit as far as possible from fluorescent lamps.
If a wireless kit is installed in a room where the electronic lighting type (inverter or rapid start types) fluo-
rescent lamps exist, the transmitting distance of a remote controller may be shorter.
• 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 may deteriorate and cause parts to fall off or water to leak.
2. Where corrosive gas, such as sulphurous acid gas, is produced.
Corrosion of copper pipes or brazed parts may occur and cause refrigerant leakage.
3. Where there is a machine that generates electromagnetic wave and where voltage fluctuation often
occurs such as a factory.
Control system may malfunction and as a result the unit may not properly operate.
4. Where flammable gas may leak, where carbon fibre or ignitable dust is suspending 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.
• The air conditioner is not intended for use in a potentially explosive atmosphere.
