ŒObserve these safety precautions for your safety. ŒThis equipment may have adverse effects on the equipment on the same power supply system. ŒContact the local power authority before connecting to the system. Symbol explanations WARNING This symbol indicates that failure to follow the instructions exactly as stated poses the risk of serious injury or death. CAUTION This symbol indicates that failure to follow the instructions exactly as stated poses the risk of serious injury or damage to the unit. Indicates an action that must be avoided. Indicates important instructions. Indicates a parts that requires grounding. Indicates that caution must be taken with rotating parts. (This symbol is on the main unit label.) Indicates that the parts that are marked with this symbol pose a risk of electric shock. (This symbol is on the main unit label.) WARNING Carefully read the labels affixed to the main unit. WARNING Do not use refrigerant other than the type indicated in the manuals provided with the unit and on the nameplate. Only use accessories (i.e., air cleaners, humidifiers, electric heaters) recommended by Mitsubishi Electric. Doing so may cause the unit or pipes to burst, or result in explosion or fire during use, during repair, or at the time of disposal of the unit. It may also be in violation of applicable laws. MITSUBISHI ELECTRIC CORPORATION cannot be held responsible for malfunctions or accidents resulting from the use of the wrong type of refrigerant. Do not make any modifications or alterations to the unit. Consult your dealer for repair. Improper repair may result in water leakage, electric shock, or fire. Do not touch the heat exchanger fins with bare hands. Ask your dealer or a qualified technician to install the unit. The fins are sharp and pose a risk of cuts. Improper installation by the user may result in water leakage, electric shock, or fire. Properly install the unit according to the instructions in the Installation Manual. Properly install the unit on a surface that can withstand its weight. Improper installation may result in water leakage, electric shock, or fire. Unit installed on an unstable surface may fall and cause injury. Only use specified cables. Securely connect each cable so that the terminals do not carry the weight of the cable. Have all electrical work performed by an authorized electrician according to the local regulations and the instructions in this manual. Use a dedicated circuit. Improperly connected cables may produce heat and start a fire. Insufficient power supply capacity or improper installation of the unit may result in malfunctions of the unit, electric shock, or fire. Take appropriate safety measures against wind gusts and earthquakes to prevent the unit from toppling over. Improper installation may cause the unit to topple over and cause injury or damage to the unit. HWE12090 i GB WARNING Keep electrical parts away from water. After completing the service work, check for a refrigerant leak. Wet electrical parts pose a risk of electric shock, smoke, or fire. If leaked refrigerant is exposed to a heat source, such as a fan heater, stove, or electric grill, toxic gases will be generated. Securely attach the control box cover. If the cover is not installed properly, dust or water may infiltrate and pose a risk of electric shock, smoke, or fire. Do not try to defeat the safety features of the unit. Only use the type of refrigerant that is indicated on the unit when installing or relocating the unit. Forced operation of the pressure switch or the temperature switch by defeating the safety features for these devices, or the use of accessories other than the ones that are recommended by Mitsubishi Electric may result in smoke, fire, or explosion. Infiltration of any other types of refrigerant or air into the unit may adversely affect the refrigerant cycle and may cause the pipes to burst or explode. Consult your dealer for proper disposal method. Consult your dealer or a qualified technician when moving or reinstalling the unit. Improper installation may result in water leakage, electric shock, or fire. Precautions for handling units for use with water CAUTION Do not use the existing water piping. Only use water. Store the piping materials indoors, and keep both ends of the pipes sealed until immediately before installation. Keep the joints wrapped in plastic bags. If dust or dirt enters the water circuit, it may damage the heat exchanger and cause water leakage. Only use clean water as a refrigerant. The use of water outside the specification may damage the refrigerant circuit.
