1.6 MAINTENANCE DATA 1.6.1 Servicing Evacuation The evacuation is a procedure to purge impurities, such as noncondensable gas, air, moisture from the refrigeration circuit by using a vacuum pump. Since the refrigerant R410A is very insoluble in water, even a small amount of moisture left in the refrigeration circuit will freeze, causing what is called ice clogging.
Page 263: Trouble Shooting For Refrigerant Circuit
Refrigerant charging After the evacuation shown in the above, change the connection of the charge hose to the refrigerant cylinder. (b) Purge air from the charge hose First loosen the connecting portion of the charge hose at the gauge manifold side and open valve for a few seconds, and then immediately retighten it after observing that gas has blown out from loosened connecting portion.
