CAUTION

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)".

CAUTION

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.

CAUTION

2-3.ADJUSTMENT OF ENGINE IDLING SPEED

CAUTION

Refer to the separate manual "GENERAL INFORMATION/AFTER INSTALLATION" for details on what to do after installation. (Document code: AOAMC-01*/Document part number: 988963-475*)

STANDARD AMOUNT OF REFRIGERANT 490 ± 30 g (1.08 ± 0.7 lbs)

Ensure to fill the refrigerant to the specified amount.

245 - 392 N(25 - 40 kgf, 55 - 88 lbf)

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.

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.)
