SAFETY PRECAUTIONS 1.
Before installation and electric work
s Before installing the unit, make sure you read all the “Safety precautions”. s The “Safety precautions” provide very important points regarding safety. Make sure you follow them.
•
• •
s This equipment may cause the adverse effect on the same supply system. s Please report to or take consent by the supply authority before connection to the system.
•
•
Symbols used in the text Warning: Describes precautions that should be observed to prevent danger of injury or death to the user.
Caution: Describes precautions that should be observed to prevent damage to the unit.
Symbols used in the illustrations

: Indicates an action that must be avoided. : Indicates that important instructions must be followed. : Indicates a part which must be grounded.
•
: Indicates that caution should be taken with rotating parts. (This symbol is displayed on the main unit label.) : Beware of electric shock (This symbol is displayed on the main unit label.)
Warning:

1
Ask the dealer or an authorized technician to install the air conditioner. - Improper installation by the user may result in water leakage, electric shock, or fire. Install the air unit at a place that can withstand its weight. - Inadequate strength may cause the unit to fall down, resulting in injuries. Use the specified cables for wiring. Make the connections securely so that the outside force of the cable is not applied to the terminals. - Inadequate connection and fastening may generate heat and cause a fire. Prepare for typhoons and other strong winds and earthquakes and install the unit at the specified place. - Improper installation may cause the unit to topple and result in injury. Always use an air cleaner, humidifier, electric heater, and other accessories specified by Mitsubishi Electric. - Ask an authorized technician to install the accessories. Improper installation by the user may result in water leakage, electric shock, or fire.
•
•
• •
Never repair the unit. If the air conditioner must be repaired, consult the dealer. - If the unit is repaired improperly, water leakage, electric shock, or fire may result. Do not touch the heat exchanger fins. - Improper handling may result in injury. If refrigerant gas leaks during installation work, ventilate the room. - If the refrigerant gas comes into contact with a flame, poisonous gases will be released. Install the air conditioner according to this Installation Manual. - If the unit is installed improperly, water leakage, electric shock, or fire may result. Have all electric work done by a licensed electrician according to “Electric Facility Engineering Standard” and “Interior Wire Regulations”and the instructions given in this manual and always use a special circuit. - If the power source capacity is inadequate or electric work is performed improperly, electric shock and fire may result. Keep the electric parts away from water (washing water etc.). - It might result in electric shock, catching fire or smoke. Securely install the cover of control box and the panel. - If the cover and panel are not installed properly,dust or water may enter the outdoor unit and fire or electric shock may result. When installing and moving the air conditioner to another site, do not charge the it with a refrigerant different from the refrigerant specified on the unit. - If a different refrigerant or air is mixed with the original refrigerant, the refrigerant cycle may malfunction and the unit may be damaged. If the air conditioner is installed in a small room, measures must be taken to prevent the refrigerant concentration from exceeding the safety limit even if the refrigerant should leak. - Consult the dealer regarding the appropriate measures to prevent the safety limit from being exceeded. Should the refrigerant leak and cause the safety limit to be exceeded, hazards due to lack of oxygen in the room could result. When moving and reinstalling the air conditioner, consult the dealer or an authorized technician. - If the air conditioner is installed improperly, water leakage, electric shock, or fire may result. After completing installation work, make sure that refrigerant gas is not leaking. - If the refrigerant gas leaks and is exposed to a fan heater, stove, oven, or other heat source, it may generate noxious gases. Do not reconstruct or change the settings of the protection devices. - If the pressure switch, thermal switch, or other protection device is shorted and operated forcibly, or parts other than those specified by Mitsubishi Electric are used, fire or explosion may result. To dispose of this product, consult your dealer. Do not use a leak detection additive.

Precautions for devices that use R410A or R407C refrigerant Caution:
•
•
•
•
•
•
•
•
• •
Do not use the existing refrigerant piping. - The old refrigerant and refrigerator oil in the existing piping contains a large amount of chlorine which may cause the refrigerator oil of the new unit to deteriorate. Use refrigerant piping made of C1220 (Cu-DHP) phosphorus deoxidized copper as specified in the *JIS H3300 “Copper and copper alloy seamless pipes and tubes”. In addition, be sure that the inner and outer surfaces of the pipes are clean and free of hazardous sulphur, oxides, dust/dirt, shaving particles, oils, moisture, or any other contaminant. - Contaminants on the inside of the refrigerant piping may cause the refrigerant residual oil to deteriorate. *JIS: Japanese Industrial Standard Store the piping to be used during installation indoors and keep both ends of the piping sealed until just before brazing. (Store elbows and other joints in a plastic bag.) - If dust, dirt, or water enters the refrigerant cycle, deterioration of the oil and compressor trouble may result. Use ester oil, ether oil or alkylbenzene (small amount) as the refrigerator oil to coat flares and flange connections. - The refrigerator oil will degrade if it is mixed with a large amount of mineral oil. Use liquid refrigerant to fill the system. - If gas refrigerant is used to seal the system, the composition of the refrigerant in the cylinder will change and performance may drop. Do not use a refrigerant other than R410A or R407C. - If another refrigerant (R22, etc.) is used, the chlorine in the refrigerant may cause the refrigerator oil to deteriorate. Use a vacuum pump with a reverse flow check valve.. - The vacuum pump oil may flow back into the refrigerant cycle and cause the refrigerator oil to deteriorate. Do not use the following tools that are used with conventional refrigerants. (Gauge manifold, charge hose, gas leak detector, reverse flow check valve, refrigerant charge base, vacuum gauge, refrigerant recovery equipment) - If the conventional refrigerant and refrigerator oil are mixed in the R410A or R407C, the refrigerant may deteriorated. - If water is mixed in the R410A or R407C, the refrigerator oil may deteriorate. - Since R410A or R407C does not contain any chlorine, gas leak detectors for conventional refrigerants will not react to it. Do not use a charging cylinder. - Using a charging cylinder may cause the refrigerant to deteriorate. Be especially careful when managing the tools. - If dust, dirt, or water gets in the refrigerant cycle, the refrigerant may deteriorate.
