The discharge from a rupture disc should be piped __________ for venting?

The EPA 608 Type III exam certifies technicians to service low-pressure appliances (e.g., centrifugal chillers) and covers leak detection, repair, and refrigerant recovery/recharging techniques. Key topics include R-123/R-1233zd safety, evacuation procedures, rupture disc discharge, and 72% passing rates.  Key Exam Topics for Type III (Low-Pressure Systems): Leak Detection and Repair: Identifying leaks in low-pressure systems, as they operate in a vacuum, focusing on excessive purging. Leak Test Pressurization: Using hot water or systems to increase pressure for leak testing. Recovery... Show more

Leak Test Pressurization: Using hot water or systems to increase pressure for leak testing.
Recovery Techniques: Proper procedures for recovering refrigerant from low-pressure equipment.
Charging and Evacuation: Proper charging techniques, including introducing vapor before liquid to avoid freezing water in tubes.
Safety and Regulations: Understanding the "three R's" (recover, recycle, reclaim), environmental impact (ozone depletion), and handling R-11, R-123, or R-1233zd.
Equipment Components: Knowledge of rupture discs and proper venting. 

Exam Structure:
Type III Section: 25 multiple-choice questions.
Passing Score: 72% (18 out of 25 questions).
