ERROR CONTENTS (outdoor unit). Make a TEST RUN in accordance with the installation instruction sheet for the indoor unit.. OUTDOOR UNIT LEDS When a malfunction occurs in the outdoor unit, the LED on the circuit board lights to indicate the error. Refer to the following table for the description of each error according to the LED. LED flash flash flash flash 7 flash 8 flash 9 flash flash flash flash flash 6 flash lighting Error contents Communication error (Indoor unit - Outdoor unit) Discharg pipe temperature sensor Outdoor heat exchanger temperature sensor Outdoor temperature sensor Compressor temperature sensor Heat sink temperature sensor Pressure switch abnormal IPM error Compressor rotor position cannot detect Compressor cannot operate Outdoor fan abnormal (upper fan) Outdoor fan abnormal (lower fan) No error. When the product is operating: Press the PUMP DOWN switch on the outdoor unit. The LED on the outdoor unit circuit board lights, and operation stops. At this point, recovery has not been completed, so do not close the two- and three-way valves. The pump down operation (cooling operation) begins after three minutes. Close the three-way valve (liquid) after operation starts. After - minutes, operation stops. Close the threeway valve (gas) within one minute after operations stops. The LED will go out three minutes after it stops. Disconnect the power supply after confirming that the LED has gone out. *When the pump down operation is repeated, temporarily disconnect the power supply after opening the closed valves (both liquid and gas). Reconnect the power supply after - minutes and perform the pump down operation. *When the start of the operation after pump down operation has been completed, temporarily disconnect the power supply after opening the closed valves (both liquid and gas). Reconnect the power supply after - minutes and be sure to perform a test operation for cooling. -way valve (Liquid) SPECIAL INSTALLATION SETTING PUMP DOWN (Refrigerant collecting operation) Perform the following procedures to collect the refrigerant when moving the indoor unit or the outdoor unit. -way valve (Gas). When the product is stopped: Press the PUMP DOWN switch on the outdoor unit. (The LED on the outdoor unit circuit board lights.) The pump down operation (cooling operation) begins right away. After oparation starts, close the three-way valve (liquid). After - minutes, operation stops. Close the threeway valve (gas) within one minute after operations stops. The LED will go out three minutes after it stops.disconnect the power supply after confirming that the LED has gone out. PUMP DOWN SW DANGER This part (Choke coil) generates high voltages.
