CAUTION:
• Replace O-rings with new ones. Then apply compressor oil to them when installing.
• Female-side piping connection is thin and easy to deform. Slowly insert the male-side piping
straight in axial direction.
• Insert piping securely until a click is heard.
• After piping connection is completed, pull male-side piping by hand to make sure that connection
does not come loose.
• O-rings differ from low-pressure flexible hose (high-pressure pipe 1) and low-pressure pipe 1 (high-
pressure pipe 2).
• Mark the mounting position of intake sensor bracket prior to removal so that the reinstalled sensor
can be located in the same position.
• Check for leakages when recharging refrigerant.
