    7.8 Evacuation Procedure: 1. Connect the vacuum pump to the charge set’s centre hose. 2. Evacuation for approximately one hour. Confirm that the gauge needle has moved toward -0.1 Mpa (-76 cmHg) [vacuum of 4 mmHg or less]. 3. Close the valve (Low side) on the charge set, turn off the vacuum pump, and confirm that the gauge needle does not move (approximately 5 minutes after turning off the vacuum pump).
