Operation Procedure for Refrigerant Charge: Evacuation

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.

Connect center charging hose (5) of manifold gauge set (A) to vacuum pump (6).
Special Tool
1. 09990-06020
Connect high charging hose (1) and low charging hose (2) of manifold gauge set respectively as follows:
- High charging hose → High pressure charging valve (3) on discharging hose
- Low charging hose → Low pressure charging valve (4) on suction hose
Operate vacuum pump, and then open discharge side valve (Hi) (7) and suction side valve (Lo) (8) of manifold gauge set.
Evacuation should be carried out for 15 minutes.
NOTE: Verify that low pressure gauge shows below -100 kPa (-1.0 kgf/cm² , -760 mmHg, -14.7 psi).

Close discharge side valve (Hi) and suction side valve (Lo).
Stop vacuum pump.
NOTE: Before turning off vacuum pump equipped with solenoid operated control valve, close manifold gauge valve first. Without closing it, turning off vacuum pump may open the A/C system to atmospheric air, and another evacuation would be required.
After completing the evacuation, wait more than 5 minutes.
Verify that low pressure gauge reading has not charged.
NOTE: If gauge reading moves closer to "0", there is a leak somewhere. Inspect the tubing connections and make necessary corrections.
Then, evacuate system once again and make sure that there is no leak.
