Regulations & Safety第 76 / 240 题
A technician using self-contained (active) recovery equipment on a high-pressure system should connect and operate it so that:
a.Refrigerant vents through the machine to the outdoors
b.The machine runs without any recovery cylinder attached
c.Recovered refrigerant is captured in an approved cylinder and the system reaches the required evacuation level
d.Oil and refrigerant are blown out to atmosphere first
解析
Self-contained recovery equipment must be set up so recovered refrigerant is captured in an approved recovery cylinder and the appliance is evacuated to the level required for that equipment type. Venting through the machine, running with no cylinder attached, or blowing out oil and refrigerant would all release refrigerant illegally. Following the recovery machine's procedure ensures both compliance and safety.
