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 conductor 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.
•
Install the indoor and outdoor units, power cord and connecting wires at least 1 meter away from televisions
or radios in order to prevent image interference or noise.
(Depending on the radio waves, a distance of 1 meter may not be sufficient enough to eliminate the noise.)
•
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
•
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.
2-1 PRECAUTIONS
•
Be sure to read this manual before installing the indoor unit.
•
Entrust installation to the place of purchase or a qualified serviceman. Improper installation could lead to
leaks and, in worse cases, electric shock of fire.
•
When installing the unit in a small room, take measures against to keep refrigerant concentration from
exceeding allowable safety limits in the event of refrigerant leakage. Contact the place of purchase for more
information. Excessive refrigerant in a closed ambient can lead to oxygen deficiency.
•
Use only parts provided with the unit or parts satisfying required specifications. Unspecified parts could
cause the unit to fall out of place, or could lead to leaks and, in worse cases, electric shock or fire.
•
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 deteri-
orate which could eventually cause the unit to fall out of place, or could lead to leaks.)
