What makes a piece of recovery equipment 'system-dependent'?

It relies on the appliance's own components, such as its compressor.

  1. It only recovers liquid refrigerant
  2. It can only be used on one brand of appliance
  3. It needs components in the appliance to remove the refrigerant ✔

Why: System-dependent (passive) equipment cannot pull refrigerant out by itself. It depends on the appliance's own parts to help. Self-contained equipment has its own means, so it works without the appliance.

Huh, didn't know that: Self-contained equipment can remove refrigerant 'without the assistance of components contained in the appliance'.
