[MANUAL AIR CONDITIONER (HR/MR)]

LOW-PRESSURE PIPE 1 AND HIGH-PRESSURE PIPE 2

9.

Disconnect Heater and cooling unit harness connectors from steering member main harness.

10. Remove steering member.
11. Remove heater and cooling assembly. Refer to

VTL-32, "Removal and Installation"

.

12. Remove mounting screws, and then remove evaporator cover

(1).

13. Using a thin cutter, cut the evaporator insulator (B), and then

remove fixing bolt (A) and low-pressure pipe 1 and high-pres-
sure pipe 2 assembly.

CAUTION:

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

INSTALLATION

Installation is basically the reverse order of removal.

CAUTION:

• Replace O-rings of high-pressure pipe 1, 2 and low-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.

• When recharging refrigerant, check for leaks.
