Remove the brace and the shroud. (Refer to section 2.2.2) 2. Remove the 4 screws which fasten the shroud. (Refer to section 2.2.2) 3. Push forward the shroud and remove the 2 screws which fasten the condenser with the basepan. 4. After discharging the refrigerant completely, unbraze the interconnecting tube at the condenser connections. 5. Remove the condenser. 6. Re-install the components by referring to notes. (See Figure 15) 2.4.2 EVAPORATOR 1. Remove the front grille. (Refer to section 2.1.1) 2. Discharge the refrigerant completely. 3. Remove the control box assembly. (Refer to section 2.1.2) 4. Remove the 4 screws which fasten the evaporator at the left side and the right side. 5. Move the evaporator sideward carefully and then unbraze the interconnecting tube at the evaporator connectors. 6. Remove the evaporator. 7. Re-install the components by referring to notes. (See Figure 16) 2.4.3 CAPILLARY TUBE 1. After discharging the refrigerant completely, unbraze the interconnecting tube at the capillary tube. 2. Remove the capillary tube. 3. Re-install the components by referring to notes. Figure 15 Figure 156 Downloaded from www.Manualslib.com manuals search engine -18-
