(1) Connect a hose to the liquid/gas/high pressure gas pipes and make the vacuum with a vacuum

pump.

(2) The equal oil pipe has gas type of refrigerants. Purge oxygen inside the equal oil pipe.

(3) Compare the external temperature with the temperature below. Keep the vacuum until the

gauge pressure reaches the value in the below table. (For more than 2-and–a-half hours)
