To recover refrigerant is to: - Remove refrigerant is any condition from a system in either an active or passive manner, and store it in an external container without necessarily testing or processing. The required evacuation level for recovering refrigerant from a low pressure appliance with a recovery machine manufactured AFTER November 15, 1993 is: - 25 mm Hg absolute The process that reduces contaminate in used refrigerant by oil separation with single and multiple passes through device...

Recovery cylinders used with R-410A must have a DOT rating of: - Answer either "DOT 4BA 400" or "DOT 4BW 400" A system using R-410A refrigerant has bubbles in the sight glass. Technician A says that the system must be low on refrigerant. Technician B says that the bubbles could be caused by the blended refrigerant flashing in the increased volume of the sight glass. Who is correct? - Answer Technician B only When charging a R-410A system that uses a thermostatic expansion...

be connected as far away from the pump as possible a high capacity vacuum pump and short, large diameter hoses will dramatically reduce emissions, pressure drop, and evacuation/dehydration time ozone contains three oxygen atoms one chlorine atom can destroy 100,000 ozone molecules CFC's do not dissolve in water and do not breakdown into other compounds that dissolve in water CFC's cannot be washed out of the lower atmosphere ODP ozone depletion potentia...
