Removal
• When working on high voltage system, the work should be carried by technicians who have completed the relevant training. A lack of understanding of the high voltage system can lead to serious accidents due to electric shock or electric leakage.
• When working a high voltage system, the technician must be observed and aware of "High Voltage System General Safety Information and Caution". If not, it may cause serious accidents such as electric shock or short circuit.
• When working on high voltage system, make sure to check the Personal Protective Equipment (PPE) and high voltage shut-off procedures.
3-way valve
1.Disconnect the battery negative ( - ) terminal and the service interlock connector.(Refer to Battery Control System - "Auxiliary 12 V Battery - 2WD")(Refer to Battery Control System - "Auxiliary 12 V Battery - 4WD")
2.Remove the water condenser.(Refer to Air Conditioning - "Water Condenser")
3.Disconnect the 3-way valve connector (A).
4.Remove the 3-way valve.
(1)Separate the refrigerant direction control valve pipes (A) after removing the bolt and nuts.
(2)Remove the 3-way valve (B).
Installation
• When working on high voltage system, the work should be carried by technicians who have completed the relevant training. A lack of understanding of the high voltage system can lead to serious accidents due to electric shock or electric leakage.
• When working a high voltage system, the technician must be observed and aware of "High Voltage System General Safety Information and Caution". If not, it may cause serious accidents such as electric shock or short circuit.
• When working on high voltage system, make sure to check the Personal Protective Equipment (PPE) and high voltage shut-off procedures.
• Be sure to inject the specified refrigerant (R-1234yf) and refrigeration oil (POE) by using the refrigerant recovery/charging equipment dedicated to the electric compressor. Compressor damage and safety accidents may occur if refrigeration oil (PAG) of general vehicles is mixed.
• Replace the O-rings at each connection with new ones, and apply a few drops of compressor oil (refrigerant oil) to the O-rings before connecting hoses or lines. To avoid leakage of R-1234yf, use the specified O-ring.
• Charge the refrigerant system and test the air conditioner performance.
1.Install in reverse order of removal.
