SAFETY SUMMARY
IMPORTANT NOTICE
●We pursue a policy of continuing improvement in design and performance of products. The right is
therefore reserved to vary specifications without notice.
●We cannot anticipate every possible circumstance that might involve a potential hazard.
●This air conditioner is designed for standard air conditioning only. Do not use this air conditioner for
other purposes such as drying clothes, refrigerating foods or for any other cooling or heating process.
Do not let the air-out face animals or plants, it might have an adverse effect on them.
●The installer and system specialist shall secure safety against leakage according to local regulations
or standards.
●Signal words (DANGER, WARNING and CAUTION) are used to identify levels of hazard seriousness.
Definitions for identifying hazard levels are provided below with their respective signal words.
●Installation should be performed by the dealer or other professional personnel. Improper installation
may cause water leakage, electrical shock, or fire.
●Do not perform installation work, refrigerant piping work, drain piping and electrical wiring connection
without referring to our installation manual. If the instructions are not followed, it may result in water
leakage, electric shock or fire.
●Use refrigerant R410A in the refrigerant cycle.
●Do not pour water into the indoor or outdoor unit. These products are equipped with electrical parts. If
poured, it will cause a serious electrical shock.
●Do not open the service cover or access panel for the indoor or outdoor units without turning OFF the
main power supply.
●Do not touch or adjust safety devices inside the indoor or outdoor units. If these devices are touched
or readjusted, it may cause a serious accident.
●Refrigerant leakage can cause difficulty in breathing due to insufficient air. Turn OFF the main switch,
extinguish any naked flames and contact your service contractor, if refrigerant leakage occurs.
●Do perform air-tight test. Do not charge oxygen, acetylene or other flammable and poisonous gas into
the refrigerant cycle when performing a leakage test or an air-tight test. These types of gas are
extremely dangerous and can cause an explosion. It is recommended that nitrogen be used for this
test.
●The installer and system specialist shall secure safety against refrigerant leakage according to local
regulations or standards.
●Use an ELB (Electric Leakage Breaker). In the event of a fault, there is danger of an electric shock or
a fire if it is not used.
Immediate hazards which WILL result in severe personal injury or death.
Hazards or unsafe practices which COULD result in severe personal injury or
death.
Hazards or unsafe practices which COULD result in minor personal injury or
product or property damage.
Useful information for operation and/or maintenance.
●Do not use any sprays such as insecticide, lacquer, hair spray or other flammable gas within
approximately one (1) meter from the system.
●If circuit breaker or fuse is often activated, stop the system and contact your service contractor.
●Check that the ground wire is securely connected. If the unit is not correctly grounded, it will lead
to electric shock. Do not connect the ground wiring to gas piping, water piping, lightning
conductor or ground wiring for telephone.
●Before performing any brazing work, check to ensure that there is no flammable material around
when using refrigerant. Be sure to wear leather gloves to prevent cold injuries.
●Protect the wires, electrical parts, etc. from rats or other small animals.
If not protected, rats may gnaw at unprotected parts, which may lead to fire.
●Fix the cables securely. External forces on the terminals could lead to a fire.
●Install the air conditioner on a solid base that can support the unit weight. An inadequate base or
incomplete installation may cause injury in the event the unit falls off the base. Incomplete
connections or clamping may cause terminal overheating or fire.
●Make sure that the outdoor unit is not covered with snow or ice, before operation.
●Do not step or put any material on the product.
●Do not put any foreign material on the unit or inside the unit.
●It is recommended that the room be ventilated every 3 to 4 hours.
●The air conditioner may not work properly under the following circumstances.
The power transformer provides the same power with the air conditioner. The electrical equipment
is too close to the power supply of the air conditioner. With the sharp change of power
consumption and switching action, the power supply of the air conditioner will generate a large
induction surge voltage.
CHECKING PRODUCT RECEIVED
●Upon receiving this product, inspect it for any shipping damage. Claims for damage, either apparent
or concealed, should be filed immediately with the shipping company.
●Check the model number, electrical characteristics (power supply, voltage and frequency) and
accessories to determine if they are correct.
The standard utilization of the unit shall be explained in these instructions.
Therefore, the utilization of the unit other than those indicated in these instructions is not
recommended.
Please contact your local agent, as the occasion arises.
The figures in this manual are based on the external view of a standard model.
Consequently, the shape may differ from that of the air conditioner you have selected.
