CS-XE9CKE CU-XE9CKE / CS-XE12CKE CU-XE12CKE 12 Servicing Information Caution: • • • • Pb free solder has a higher melting point than standard solder; Typically the melting point is 50 - 70°F (30 - 40°C) higher. Please use a high temperature soldering iron. In case of the soldering iron with temperature control, please set it to 700 ± 20°F (370 ± 10°C). - Page 83 CS-XE9CKE CU-XE9CKE / CS-XE12CKE CU-XE12CKE Troubleshooting Air Conditioner Refrigeration cycle system In order to diagnose malfunctions, make sure that there are no electrical problems before inspecting the refrigeration cycle.
