What is NOT required to mothball an appliance to extend the leak repair deadline?

To mothball an appliance and extend the deadline for leak repairs, certain actions are typically required to ensure that the appliance does not continue to leak refrigerants into the atmosphere. The correct choice highlights that removing the appliance and storing it in a warehouse is not a requirement for this process.

Mothballing an appliance generally involves sealing it to prevent leaks (which helps to contain any refrigerants), documenting the mothballing process for compliance and recordkeeping purposes, and possibly performing a thorough cleaning to ensure that it remains in a condition that could be safely restored to service.

While storing the appliance away from the facility might seem like a precautionary measure, it is not mandated as part of the mothballing process. The key aspect of mothballing is primarily about effectively sealing and documenting it. Therefore, the specified action of warehouse storage does not align with the core requirements to mothball an appliance adequately.
