4. Recovery Tank Usage

The recovery tank is a critical component in the manual recovery process. It is responsible for collecting and storing the refrigerant until it can be disposed of or recycled. When selecting a recovery tank, technicians should consider its size. A medium-sized tank is typically recommended because it offers a good balance between portability and capacity. Moreover, it is essential that the tank is equipped with a service valve and a pressure relief device to ensure safe handling.

5. Importance Of Inline Filter

During the recovery process, it is crucial to use an inline filter to prevent contaminants like oil or debris from entering the recovery tank. The inline filter should be installed between the recovery device (e.g., hose or recovery machine) and the recovery tank. This filter captures impurities, ensuring that the recovered refrigerant maintains its integrity. By reducing the risk of contamination, the inline filter enables the refrigerant to be suitable for reuse or recycling.

6. Proper Tank Evacuation

Before recovering refrigerant, it is essential to properly evacuate the recovery tank to eliminate any contaminants, such as moisture or air. This step is crucial for ensuring the successful recovery of clean refrigerant. Technicians should use a vacuum pump to evacuate the tank and allow the pressure inside to reach the desired level. Proper evacuation helps minimize the presence of non-condensable gases that can affect the efficiency of future refrigerant recovery.
