11. Remove mounting nuts and bolts, and then remove instrument stays (left and right side).
12. Remove mounting bolts from heater & cooling unit assembly.
13. Disconnect drain hose.
14. Remove center and side ventilator ducts, defroster nozzle and side defroster ducts. Refer to ATC-116,
"Removal and Installation".
15. Remove steering column mounting bolts and nut.
16. Remove steering member mounting bolts, nut and harness clips.
17. Remove steering member, and then remove heater & cooling unit assembly.
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 c onnection 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 comple ted, pull male-side piping by hand to make sure that connection
does not come loose.
 When recharging refrigerant, check for leaks.

SETTING OF SERVICE TOOLS AND EQUIPMENT
Discharging Refrigerant
WARNING:
Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and
throat. Remove HFC-134a (R-134a) from A/C system using certified service equipment meeting
requirements of SAE J-2210 [HFC-134a (R-134a) recycling equipment] or J-2209 [HFC-134a (R-134a)
recovery equipment]. If accidental system discharge occurs, ventilate work area before resuming ser-
vice. Additional health and safety information may be obtained from refrigerant and lubricant manu-
facturers.
