8. AIR EVACUATION
8.1. Preparations and Precautions
Air and foreign matter in the refrigerant circuit can cause abnormal rises in pressure, which can damage the air
conditioner, reduce its efficiency, and cause injury. Use a vacuum pump and manifold gauge to evacuate the
refrigerant circuit, removing any non-condensable gas and moisture from the system.
Evacuation should be performed upon initial installation and when unit is relocated.
BEFORE PERFORMING EVACUATION
