Core (Universal)Câu 13 / 240
A technician is about to replace a compressor on a residential R-410A split system. Before opening the sealed system, the technician must:
a.Vent the refrigerant slowly so it disperses safely
b.Let the refrigerant leak out while purging with nitrogen
c.Discharge the refrigerant into a bucket of water
d.Recover the refrigerant into an approved recovery cylinder using recovery equipment
Giải thích
Section 608 requires that refrigerant be recovered into an approved recovery cylinder using recovery equipment before a sealed system is opened for service or disposal. Venting, purging to atmosphere, or discharging into water are all illegal releases. Knowingly venting refrigerant is prohibited and can lead to significant penalties.
