What are the factors that affect the speed and efficiency of evacuation?

The factors that affect the speed and efficiency of evacuation are; size of equipment being
evacuated, ambient temperature, amount of moisture in the system, the size of the vacuum
pump and vacuum lines, Figures 10 & 11. In addition, vacuum lines (hoses) should be equal
to or larger than the pump intake connection. The brand of a micron gauge does not usually
affect the speed of evacuation, but the method used to connect it to the system may. The
piping connection to the vacuum pump should be as short in length as possible and as large
in diameter as possible. For accurate readings during evacuation, the system vacuum gauge
should be connected as far away from the vacuum pump as possible. Measuring a final
system vacuum should be done with the system isolated and the vacuum pump turned off. A
system that will not hold a vacuum after it has been evacuated probably has a leak. During
evacuation, you may wish to heat the refrigeration system to decrease dehydration time.
Tapping a compressor with a rubber mallet will aid in releasing trapped refrigerant from the oil.
