# Group 64 Heating and Air Conditioning Index

Any time the air conditioning refrigerant circuit is openings should be plugged immediately to prevent contamination of the system. Failure to close the system immediately will cause damage to the receiver drier. As soon as possible after the system is reassembled, a vacuum should be drawn on it, to check for leaks, and to remove moisture from the system before it contaminates the receiver drier. Even if the system is not to be filled with refrigerant for some time, a vacuum should be pulled and maintained on the system.
