Removal and Installation of Evaporator
REMOVAL
1. Remove low-pressure pipe 1 and high-pressure pipe 2. Refer to "Removal and Installation of Low-pressure Pipe 1 and High-pressure Pipe 2".
CAUTION: Cap or wrap the joint of evaporator, low-pressure flexible hose and high-pressure pipe 1 with suitable material such as vinyl
tape to avoid the entry of air.
2. Slide evaporator, and then remove it from heater & cooling unit assembly.
3. Remove intake sensor from evaporator, and then remove evaporator.
INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:
-
Replace O-rings of low-pressure flexible hose, low-pressure pipe 1 and high-pressure pipe 1, 2 with new ones, and then apply compressor
oil to it when installing it.
-
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 are different 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.
-
When recharging refrigerant, check for leaks.
