Appion Inc. Offers Tips on Removing Restrictions for Fast Refrigerant Recovery

This can make it tempting for a technician on a tight schedule to skip the recovery process. However, with the proper understanding of equipment and methods, refrigerant recovery can be faster and easier than venting. Just like tires can affect a car’s performance, the hoses, fittings, manifold, and recovery cylinder all play a role in how quickly and efficiently the recovery process is completed.
