Mitsubishi Air Conditioning Safety Precautions

Since rotating parts and parts which could cause an electric shock are used in this product, be sure to read these “Safety Precautions” before use.

• Since the cautionary items shown here are important for safety, be sure to observe them.

• After reading this manual, keep it together with the installation manual in a handy place for easy reference.

  • Be sure to receive a guarantee card from your dealer and check that the purchased data and shop name, etc. are entered correctly.

Warnings

Do not connect the power cord to an intermediate point, use an extension cord, or connect multiple devices to a single AC outlet. This may cause overheating, fire, or electric shock.
Make sure the power plug is free of dirt and insert it securely into the outlet. A dirty plug may cause fire or electric shock.
Do not bundle, pull, damage, or modify the power cord, and do not apply heat or place heavy objects on it. This may cause fire or electric shock.
Do not turn the breaker OFF/ON or disconnect/connect the power plug during operation. This may create sparks, which can cause fire. • After the indoor unit is switched OFF with the remote controller, make sure to turn the breaker OFF or disconnect the power plug.
Do not expose your body directly to cool air for a prolonged length of time. This could be detrimental to your health.
The unit should not be installed, relocated, disassembled, altered, or repaired by the user. An improperly handled air conditioner may cause fire, electric shock, injury, or water leakage, etc. Consult your dealer. If the power supply cord is damaged, it must be replaced by the manufacturer or its service agent in order to avoid a hazard.
When installing, relocating, or servicing the unit, make sure that no substance other than the specified refrigerant (R410A) enters the refrigerant circuit. Any presence of foreign substance such as air can cause abnormal pressure rise and may result in explosion or injury. The use of any refrigerant other than that specified for the system will cause mechanical failure, system malfunction, or unit break- down. In the worst case, this could lead to a serious impediment to securing product safety.
This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appli- ance by a person responsible for their safety.
Children should be supervised to ensure that they do not play with the appliance.

Do not insert your finger, a stick, or other objects into the air
inlet or outlet.
This may cause injury since the fan inside rotates at high speeds during operation.
In case of an abnormal condition (such as a burning smell), stop the air conditioner and disconnect the power plug or turn the breaker OFF.
A continued operation in an abnormal state may cause a malfunction, fire, or electric shock. In this case, consult your dealer.
When the air conditioner does not cool or heat, there is a possibility of refrigerant leakage. In this case, consult your dealer. If a repair involves recharging the unit with refrigerant, ask the service technician for details.
The refrigerant used in the air conditioner is safe. Normally, it does not leak. However, if refrigerant leaks and comes in contact with a heat source such as a fan heater, kerosene heater, or cooking stove, it will create a harmful gas.
The user should never attempt to wash the inside of the indoor unit. Should the inside of the unit require cleaning, contact your dealer.
The unsuitable detergent may cause damage to plastic material inside the unit, which may result in water leakage. Should detergent come in contact with electrical parts or the motor, it will result in a malfunction, smoke, or fire.

Do not expose pets or houseplants to direct airflow.
This may cause injury to the pets or plants.

Do not place other electric appliances or furniture under the indoor/outdoor unit.
Water may drip down from the unit, which may cause damage or malfunction.

Do not leave the unit on a damaged installation stand.
The unit may fall and cause injury.

Do not step on an unstable bench to operate or clean the unit.
This may cause injury if you fall down.

Do not pull the power cord.
This may cause a portion of the core wire to break, which may
cause overheating or fire.

Do not charge or disassemble the batteries, and do not throw
them into a fire.
This may cause the batteries to leak, or cause a fire or explosion.

Do not operate the unit for more than 4 hours at high humidity (80% RH or more) and/or with windows or outside door left open.
This may cause water condensation in the air conditioner, which may drip down, wetting or damaging the furniture.
The water condensation in the air conditioner may contribute to the growth of fungi, such as mold.

Do not use the unit for special purposes, such as storing food, raising animals, growing plants, or preserving precision devices or art objects.
This may cause deterioration of quality or harm to animals and plants.

Do not expose combustion appliances to direct airflow.
This may cause incomplete combustion.

Never put batteries in your mouth for any reason to avoid accidental ingestion.
Battery ingestion may cause choking and/or poisoning.

Before cleaning the unit, switch it OFF and disconnect the power plug or turn the breaker OFF.
This may cause injury since the fan inside rotates at high speeds during operation.

When the unit will be unused for a long time, disconnect the power plug or turn the breaker OFF.
The unit may accumulate dirt, which may cause overheating or
fire.

Replace all batteries of the remote controller with new ones of the same type.
Using an old battery together with a new one may cause overheat- ing, leakage, or explosion.

If the battery fluid comes in contact with your skin or clothes,
wash them thoroughly with clean water.
If the battery fluid comes in contact with your eyes, wash them thoroughly with clean water and immediately seek medical attention.

Ensure that the area is well-ventilated when the unit is operated together with a combustion appliance.
• Inadequate ventilation may cause oxygen starvation.
Turn the breaker OFF when you hear thunder and there is a possibility of a lightning strike.
• The unit may be damaged if lightning strikes.
