3 1. INSTALLATION INSIDE PASSENGER COMPARTMENT CAUTION 1. Before starting installation, remove the negative cable from the battery. 2. Before making any hoses and tubes connections, apply a few drops of compressor oil to the seat of O-ring and coupling nuts. 3. When tightening and loosening the fittings, use two wrenches for support. 4. Ensure fender covers are in position. 5. Start the work from the inside passenger compartment side. VEHICLE HARNESS CAUTION First remove the negative terminal on the battery and the vehicle harness connection before installing the equipment. Disconnect the negative cable first.

(Document code: AOAMC-01*/Document part number: *) 2-1.CHARGING REFRIGERANT (HFC-134a) For additional information on charging refrigerant using the charging cylinder, refer to "GENERAL INFORMATION/AF- TER INSTALLATION: CHARGING REFRIGERANT (134a)". STANDARD AMOUNT OF REFRIGERANT 490 ± 30 g (1.08 ± 0.7 lbs) CAUTION Ensure to fill the refrigerant to the specified amount. 2-2.RE-ADJUSTMENT OF COMPRESSOR BELT (1NZ/2NZ E/G MODEL ONLY) To correct belt deflection caused by initial elongation, the air conditioning must be operated for at least 5 minutes before the final adjustment of the belt. Vehicle equipped with 1NZ/2NZ E/G Belt deflection [at 98N(10kgf, 22lbf)force] mm ( inch) Belt tension [N (kgf, lbf)] N (25-40 kgf, lbf) CAUTION 1. Excessive tension of belt may have an adverse effect on bearings, while excessive slackness can cause the belt to slip, make abnormal noise or shorten the belt life. 2. The belt deflection must be measured between the specified pulleys as indicated in this manual. 3. The belt tension must be measured between the specified pulleys as indicated in this manual. 4. The belt tension must be adjusted to the center of the specified belt tension range. 2-3.ADJUSTMENT OF ENGINE IDLING SPEED CAUTION The engine revolution is controlled by a computer, therefore adjustment is not required. (when the air conditioning system is started, check whether idling revolution increases.)
