Ammonia Refrigeration Operator III– Coming Soon!

Geared to complete the preparation to sit for and take the CIRO exam, as Operator II and Operator III combined with Operator I contains all information necessary to take the CIRO exam successfully. The attendee can expect to extensively learn the electrical portion and troubleshooting through screen displays along with a summary of all the other IR books of RETA. You can expect to understand basic digital multi-meter functions; how to read schematics associated to electrical runs; how to read a diagram showing several electrical devices including switches, buttons, relays, outputs/inputs, and resistors; and other electrical equipment expected to be used in typical refrigeration systems. In addition, attendees will be exposed to basic screen shots that will display an upset in a refrigeration system that the student will use to diagnose and evaluate for a solution. The information for this phase is achieved by working with IR-2/IR-3/BE1/BE2 and a review of the other required books for testing through RETA.
