- Standard:
- 430 +- 30 g (15.17 +- 1.06 oz.)
- SST
- 07110-58060(07117-58060,07117-58070,07117-58080,07117-58090,07117-78050,07117-88060,07117-88070,07117-88080)
- NOTICE:
| 10. WARM UP ENGINE |
Warm up the engine at less than 1,850 rpm for 2 minutes or more after charging the refrigerant.
- NOTICE:
- Be sure to warm up the compressor when turning the A/C switch ON after removing and installing the cooler refrigerant lines (including the compressor), to prevent damage to the compressor.
| 11. CHECK FOR LEAKAGE OF REFRIGERANT |
After recharging the refrigerant gas, check for refrigerant gas leakage using a halogen leak detector.
Perform the operation under the following conditions:
Using a gas leak detector, check the refrigerant line for leakage.
If a gas leak is not detected on the drain hose, remove the blower motor control (blower resistor) from the cooling unit. Insert the gas leak detector sensor into the unit and perform the test.
Disconnect the connector and leave the pressure switch on for approximately 20 minutes. Bring the gas leak detector close to the pressure switch and perform the test.
| 12. INSTALL COOL AIR INTAKE DUCT SEAL |
Install the intake duct seal with the 11 clips.
