Question 205Refrigeration & AC - Assistant Engineer

The correct answer is C) either active or passive. Technicians servicing small refrigeration appliances can employ either active or passive refrigerant recovery equipment. This is because the Clean Air Act requires that all refrigerants be properly recovered and recycled or reclaimed when servicing refrigeration and air conditioning equipment, regardless of the size or type of the appliance. Both active and passive recovery methods are approved and accepted ways to comply with the regulations on refrigerant recovery. The other options are incorrect because passive-only recovery is not sufficient, active-only recovery is not required, and there is a legal requirement to recover the refrigerant - it cannot simply be vented to the atmosphere.
