PLACING SYSTEM IN OPERATION After component replacement and/or system servicing has been completed and all connections have been made, proceed as follows: 1. Evacuate the system using a vacuum pump. Also see Refrigerant Capacity in this Section. 3. Leak test the system, with particular attention to all new connections and components. COMPRESSOR REMOVAL INFORMATION - ISOLATION METHOD On systems which have compressors equipped with stem-type service valves (Tecumseh), it is possible to isolate the compressor for removal. Isolating Turn both high and low pressure instruction valves to extreme clockwise (front seat) position. Loosen cap on high pressure manual valve COMPRESSOR REMOVAL INFORMATION-DISCHARGE METHOD This procedure is to be used on vehicles which have compressor equipped with Schrader service valves. In these cases, the compressor cannot WARNING: DO NOT open high side hand valve while air conditioning system is in operation. This high pressure CAUTION: Use ONLY "O" rings designed for these Ford fittings (Motorcraft YF-982). Normal refrigerant "O" rings Copyright 2009 Mitchell Repair Information Company, LLC.
