.

CAUTION:

Cap or wrap the joint of expansion valve, low-pressure pipe 2 and high-pressure pipe 1 with suit-
able material such as vinyl tape to avoid the entry of air.

2.

EVAPORATOR

5.

Slide evaporator (1) and intake sensor (2) from heater and cool-
ing unit assembly.

6.

Remove evaporator assembly.

7.

Cut upper insulator (3) and remove mounting bolt (A), expansion
valve and pressure pipe assembly(2), from evaporator.

INSTALLATION

Installation is basically the reverse order of removal.

CAUTION:

• Replace O-rings of low-pressure pipe 1 and high-pressure pipe 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.
