The HVAC refrigerant recovery process involves setting up equipment, purging air from hoses, activating the recovery machine to pump refrigerant into a dedicated recovery cylinder, monitoring the process, and then safely shutting down and storing the cylinder.
Recovering refrigerant is required when an EPA Universal Technician performs a major operation such as:
* Replacing a compressor
* Replacing an evaporator or condenser coil
* Opening the sealed system
* Repairing a leak
