CAUTION
•
While following the instructions in this installation manual, install drain piping to ensure proper drainage and
insulate piping to prevent condensation.
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 away from fluorescent lamps as possible.
Remote controller (wireless kit) transmitting distance can be shorter than expected in rooms with electronic
fluorescent lamps (inverter or rapid start types).
Consult your local dealer regarding what to do in case of refrigerant leakage, when the air coditioner is to
be 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 leakage. Otherwise, this may lead to
an accident due to oxygen depletion.
In a domestic environment this product may cause radio interference in which case the user may be
required to take adequate measures.
Do not allow children to climb on the outdoor unit and avoid placing objects on the unit.
Make sure to provide for adequate measure 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.
Install in a machine room that is free of moisture. The unit is designed for indoor use.
Disposal requirements
Dismantling of the unit, treatment of the refrigerant, of oil and of other parts must be done in
accordance with relevant local and national legislation.

•••
•
•
Injury may result if the unit becomes loose and falls.
•
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. Also areas that are rich in sodium such as seashores.
Corroding of copper pipes or soldered parts may result in refrigerant leakage.
3. Near machinery emitting electromagnetic radiation.
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. Where small animals may be housed, fallen leaves are accumulated, or weeds are overgrown.
If small animals touch the electrical parts inside, this may cause malfunction, smoke or fire.

SPECIAL NOTICE OF PRODUCT
• Refrigerant
• The refrigerant R410A requires that strict Precautions be
observed for keeping the system clean,
dry and tightly sealed.
A. Clean and Dry
Strict measure must be taken to keep impurities (including SUNISO oil and other mineral oils
as well as moisture) out of the system.
B. Tightly sealed
R410A contains no chlorine, does not destroy the ozone layer and so does not reduce the earth’s
protcetion against harmful ultraviolet radiation. R410A will contribute only slightly to the greenhouse
effect if released into the almosphere
• Since design pressure is 4.0 MPa or 40 bar (for R407C units: 3.3MPa or 33bar), the thickness of pipes
must be greater than previously. Since R410A is a mixed refrigerant, the required additional refrigerant
must be charged in its liquid state. (If the system is charged with refrigerant in its gaseous state, due to
composition change, the system will not function normally). The indoor units is designed for R410A use.
See the catalogue for indoor unit models that can be connected. (Normal operation is not possible when
connecting units that are originally designed for other refrigerants)
•
Do not stand on the outdoor unit or put things on it. This may result in an accident caused by falling or
dropping of items.
