Before Installation - Daikin FAY71LVE Installation Manual

• When wiring the power supply and connecting the wiring between the indoor and outdoor units, 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 the 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 the installation work, check that the refrigerant gas does not leak.
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.
• Before touching electrical parts, turn off the unit.
CAUTION
• Ground the air conditioner.
Do not connect the ground wire to gas or water pipes, lightning rods or a telephone ground wire.
Incomplete grounding may result in electric shocks.
• Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in electric shocks.
• While following the instructions in this installation manual, install drain piping in order to ensure proper
drainage and insulate piping in order to prevent condensation.
Improper drain piping may result in water leakage and property damage.
• Remote controller (wireless kit) transmitting distance can result shorter than expected in rooms with elec-
tronic fluorescent lamps (inverter or rapid start types).
Install the indoor unit as far away from fluorescent lamps as possible.
• Do not install the air conditioner in the following locations:
(a)where a mineral oil mist or an oil spray or vapor is produced, for example in a kitchen
Plastic parts may deteriorate and fall off or result in water leakage.
(b)where corrosive gas, such as sulfurous acid gas, is produced
Corroding copper pipes or soldered parts may result in refrigerant leakage.
(c) near machinery emitting electromagnetic waves
Electromagnetic waves may disturb the operation of the control system and result in a malfunction of the
equipment.
(d)where flammable gases may leak, where there are carbon fiber or ignitable dust suspensions in the air,
or where volatile flammables such as thinner or gasoline are handled.
Operating the unit in such conditions may result in fire.

2. BEFORE INSTALLATION

Do not exert pressure on the resin parts when opening the unit or when moving it after opening.
• Decide upon a line of transport.
• Leave the unit inside its packaging while moving, until reaching the installation site. Use a sling of soft mate-
rial, where unpacking is unavoidable or protective plates together with a rope when lifting, to avoid damage
or scratches to the unit.
• Refer to the installation manual of the outdoor unit for items not described in this manual.
• Installation should only be carried out after checking in advance the type of refrigerant to be used. (Using
the wrong refrigerant will prevent the unit from functioning properly.)
• Do not dispose of any parts necessary for installation until the installation is complete.
2-1 PRECAUTIONS
• Be sure to read this manual before installing the indoor unit.
• When selecting installation site, refer to the paper pattern.
• This unit is suitable for installation in a household, commercial and light industrial environment.
• 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.)
• Where corrosive gas like sulfurous gas exists. (Copper tubing and brazed spots may corrode.)
• Where volatile flammable gas like thinner or gasoline is used.
