Safety Precautions
1. Safety Precautions
The original instructions are written in English. All other languages are translations of the original
instructions.
Also see the installation manual attached to the indoor unit.
Please read these Safety Precautions carefully before installing the remote controller.
● This manual classies the precautions into WARNING and CAUTION. They both contain important
information regarding safety. Be sure to follow all the precautions below.
WARNING Failure to follow these instructions properly may result in personal
injury or loss of life.
CAUTION Failure to observe these instructions properly may result in property
damage or personal injury, which may be serious depending on the
circumstances.
● After completing the installation, conduct a trial operation to check for faults and explain to the
customer how to operate the air conditioner with the aid of the operation manual. Ask the customer
to store the installation and operation manual for future reference.
WARNING
Ask your dealer or qualied personnel to carry out installation work.
Do not attempt to install the remote controller yourself. Improper installation may result in water
leakage, electric shocks or re.
Consult your local dealer regarding relocation and reinstallation of the remote controller.
Improper installation work may result in leakage, electric shocks or re hazards.
Install the remote controller in accordance with the instructions in this installation manual.
Improper installation may result in water leakage, electric shocks or re.
Be sure to use only the specied accessories and parts for installation work.
Failure to use the specied parts may result in the unit falling down, water leakage, electric shocks
or re.
Install the remote controller on a foundation strong enough to withstand the weight of the remote
controller.
Insufcient strength may result in the remote controller falling down and causing injury.
Electrical work must be performed in accordance with the relevant local and national regulations and
with the instructions in this installation manual.
Be sure to use a dedicated power supply circuit only. Insufcient power circuit capacity and improper
workmanship may result in electric shocks or re.
Always perform installation work with the power turned off.
Touching electric parts may result in electric shock.
Do not disassemble, reconstruct or repair.
This may result in electric shock and/or re.
Make sure that all wiring is secured, the specied wires are used and that there is no strain on the
terminal connections or wires.
Improper connections or securing of wires may result in abnormal heat build-up or re.
The choice of materials and installations must comply with the applicable national and international
standards.

Safety Precautions
CAUTION
To avoid leakage and electric shock due to entry of water or insects, ll the wiring through hole with
putty.
To avoid electric shocks, do not operate with wet hands.
Do not wash the remote controller with water, as this may result in electric shocks or re.
Install the indoor and outdoor units, power cord and connection wires at least 1 meter away from
televisions or radios to prevent interference and noise.
(Depending on the incoming signal strength, a distance of 1 meter may not be sufcient to eliminate
noise.)
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 fall off which could result in water leakage.
2. Where corrosive gas, such as sulphurous acid gas, is produced.
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
malfunctioning of the unit.
4. Where ammable gas may leak, where there is carbon bre or ignitable dust suspensions in
the air or where volatile ammables such as paint thinner or gasoline are handled.
Operating the unit in such conditions may result in re.
5. High temperature areas or direct ames.
Overheating and/or re may occur.
6. Moist areas or places which may be exposed to water.
If water enters the remote controller, electric shock may be caused and the inner electronics
may fail.
When the thermostat function of the remote controller is used, select the installation location while
considering it should be a place:
● Where the average temperature in the room can be detected.
● Which is not exposed to direct sunlight.
● Which is not near a heat source.
● Which is not affected by the outside air or air draught due to, for example, opening/closing of
doors, the air outlet of the indoor unit or the like.
