Mazda CX-5 Service & Repair Manual / HVAC / A/C / Refrigerant Charging

CAUTION:

Charging Recycled HFC-134a Refrigerant

1. Connect an HFC-134a recovery/recycling/recharging device to the vehicle and follow the device manufacturer’s instructions.

Charging Preparation

1. Install the manifold gauge set.

2. Connect the tap pin side of the charging hose to the air purge valve of the manifold gauge.


3. Connect the vacuum pump hose to the center joint of the manifold gauge.

4. Connect the vacuum pump hose to the vacuum pump.

5. Connect the charging hose to the refrigerant tank.

6. Place the refrigerant tank on the scale.

Evacuation

1. Open all the valves of the manifold gauge.

CAUTION:

2. Start the vacuum pump and let it operate for 15 min

.


3. Verify that high? and low-pressure side readings of the manifold gauge are at –101 kPa {–1.03 kgf/cm2, –14.6 psi}

. Close each valve of the manifold gauge.


Airtightness Check

1. Stop the vacuum pump and wait for 5 min

.

2. Check the high? and low-pressure side readings of the manifold gauge.

Charging New HFC-134a Refrigerant

1. Open the valve of the refrigerant tank.

2. Weigh the refrigerant tank to charge the suitable amount of refrigerant.

WARNING:

3. Open the low-pressure side valve of the manifold gauge.


4. When the high-pressure side reading increases to 0.098 MPa {1.0 kgf/cm2, 14 psi}

, close the low-pressure side valve of the manifold gauge.


5. Inspect for leakage from the cooler pipe/hose connections using the gas leak tester.

6. Inspect for leakage again.

WARNING:

7. Open the low-pressure side valve of the manifold gauge and charge with refrigerant until the weight of refrigerant tank has decreased 250 g {8.82 oz}

from the amount in Step 2.


8. Close the low-pressure side valve of the manifold gauge.


WARNING:

9. Start the engine and actuate the A/C compressor.

10. Open the low-pressure side valve of the manifold gauge and charge with refrigerant until the weight of the refrigerant tank has decreased regular amount from the amount in Step 2.


11. Close the low-pressure side valve of the manifold gauge and the valve of the refrigerant tank.

12. Stop the engine and A/C compressor.

Leak Test

1. Inspect for leakage using the gas leak tester.

2. Inspect for leakage again.

3. Disconnect the quick couplers from the charging valves.

4. Install the caps to the charging valves.
