Before servicing a system, what equipment is required to handle refrigerant safely?

• A. Do nothing
• B. Proceed with service without recovery
• C. Open the service valve
• D. The refrigerant must be recovered using approved equipment

Answer: (D)

Before servicing, the refrigerant must be recovered using equipment that is approved for refrigerant recovery. This step prevents the release of refrigerant into the atmosphere, protecting the environment and complying with environmental and safety regulations. Approved recovery machines and cylinders are designed to remove the refrigerant from the system safely and contain it for reuse or proper disposal. Venting or attempting service without recovery would release refrigerant and violate laws, so recovery is mandatory before any work begins.
