Operation Procedure for Refrigerant Charge: Charge

WARNING: This page is about a different car, the 2010 Suzuki Kizashi. However, it is still accessible from the selected car via links, so may be relevant.

NOTE:

Charge the A/C system with refrigerant referring to MEASUREMENT OF CHARGING AMOUNT .
Always charge the A/C system with refrigerant through low pressure side with engine running, however the initial charge is performed from the high pressure side with the engine stopped.
When replacing refrigerant container in the process of charging, replace refrigerant container referring to REPLACEMENT OF REFRIGERANT CONTAINER .

Specified amount of refrigerant

530 ± 30 g (18.7 ± 1.1 oz)

Purge air in center charging hose as follows.
1. Make sure that discharge side valve (Hi) (1) and suction side valve (Lo) (2) are closed.
2. Install refrigerant container tap valve (4) to refrigerant container (3).
3. Install center charging hose (5) to refrigerant container.
4. Once fully tighten refrigerant container tap valve, loosen (open) it.
5. Open air purge valve (6) of manifold gauge set, and purge air in center charging hose.

Charge refrigerant to high pressure side by the following procedure.
WARNING: When charging with refrigerant from high pressure side, do not operate A/C compressor (2). Otherwise, it may cause explosion of refrigerant container or hoses by blowing back high pressure refrigerant.
1. Open discharge side valve (Hi) (3) of manifold gauge (A) and charge refrigerant with engine stopped.

2. After performing the initial charge from the high pressure side, close discharge side valve (Hi) and then disconnect high charging hose from high pressure charging valve.
Charge refrigerant to low pressure side by the following procedure.
WARNING: When charging with refrigerant from low pressure side, make sure that high pressure side valve is closed and the hose is disconnected. Otherwise, it may cause explosion of refrigerant container by blowing back high pressure refrigerant.

CAUTION: Do not reverse refrigerant container while charging refrigerant.
Reversing its container will cause liquid refrigerant to enter A/C compressor. This will cause trouble such as compression of liquid refrigerant and result in system damage.

NOTE: When replacing refrigerant container, always perform purging air in center charging hose.
1. Make sure that high pressure hose is disconnected.
2. Start engine and operate A/C system under the condition of A/C system performance inspection, see A/C SYSTEM PERFORMANCE INSPECTION .
3. Open suction side valve (Lo) (1) of manifold gauge set (A), and charge with specified amount of refrigerant.
  Measure specified amount of refrigerant referring to MEASUREMENT OF CHARGING AMOUNT .

4. After the system has been charged with specified amount of refrigerant, close suction side valve (Lo) of manifold gauge set.
Stop engine and disconnect manifold gauge set.
