1. 2 Do not install the unit where a strong wind blows or where it is very dusty 3 Do not install the unit where people pass 4 Take you neighbors into consideration so that they are not disturbed by air blowing into their windows or by noise 5 Provide the space shown in figure so that the airflow is not blocked Also for efficient operation leave open three of the four directions front rear and both sides 6 Install the outdoor unit in a location which can withstand the weight of the unit and vibration and which can install horizontally 7 Provide the indicated space to ensure good airflow 8 During heating operation drain water flows from the outdoor unit Therefore install the outdoor unit in a place where the drain water flow will not be obstructed Reverse cycle model only 9 Install the outdoor unit in a place where it will be free from being dirty or getting wet by rain as much as possible 10 Install the unit where connection to the indoor unit is easy WARNING Install at a place that can withstand the weight of the outdoor units and install positively so that the units will not topple or fall CAUTION Do not install where there is the danger of combustible gas leakage Do not install near heat sources If children under 10 years old may approach the unit take preventive measures so that they cannot reach the unit 4 INSTALLATION DIAGRAM OUTDOOR UNIT Do not directly install it2. Do not use this equipment with air or any other unspecified refrigerant in the refrigerant lines Excess pressure can cause a rupture During installation make sure that the refrigerant pipe is attached firmly before you run the compressor Do not operate the compressor under the condition of refrigerant piping not attached properly with 2 way or 3 way valve open This may cause abnormal pressure in the refrigeration cycle that leads to rupture and even injury When installing and relocating the air conditioner do not mix gases other than the specified refrigerant R410A to enter the refrigerant cycle If air or other gas enters the refrigerant cycle the pressure inside the cycle will rise to an abnormally high value and cause rupture injury etc The rated voltage 230V 50Hz WARNING The rated voltage of this product is 230 V AC 50 Hz Before turning on the power check if the voltage is within the 220 V 10 to 240 V 10 range Always use a special branch circuit and install a special receptacle to supply power to the room air conditioner Use a circuit breaker and receptacle matched to the capacity of the air conditioner Do not extend the power cable Perform wiring work in accordance with standards so that the air conditioner can be operated safely and positively Install a leakage circuit breaker in accordance with the related laws and regulations and electric company standards The circuit
