Refrigerant Charging Procedure
OPERATION
CAUTION:
-
During operation, be sure to wear safety goggles and protective gloves.
-
Before charging the refrigerant, evacuate the system to remove small amounts of moisture remaining in the system.
The moisture in the system can be completely evacuated only under the minimum vacuum level. The minimum vacuum level affects the
temperature in the system.
-
The list shows the vacuum values necessary to boil water in various temperature. In addition, the vacuum levels indicated on the gauge are approx.
3.3 kPa (25 mmHg, 0.98 in Hg) lower than those measured at 304.8 m (1,000 ft) above sea level.
1. Close the valves on low-/high-pressure sides of the manifold gauge.
2. Install the low-/high-pressure hoses to the corresponding service ports on the vehicle respectively. 3. Connect the center hose of the manifold
gauge set with the vacuum pump.
4. Carefully open the valves on the low-/high-pressure sides to activate the vacuum pump.
