Field professionals who service POU/POE residential treatment systems gain a higher level of professionalism from pursuing a CST certification. The goal of the training is for anyone servicing existing equipment to be able to not only determine and correct equipment failure, but also be able to identify the purpose of the equipment for an application and evaluate appropriate equipment size. The ability to holistically evaluate existing equipment helps minimize errors and reduce callbacks.
