Core — Recovery, Recycling and Reclamation
4 lessons- 01.01Recovery, Recycling and Reclamation — the Three R'sThree words that sound interchangeable and are legally distinct, plus the AHRI 700 purity standard and the rule that decides when refrigerant must be reclaimed.12 min
- 01.02Required Evacuation LevelsTable 1 of 40 CFR 82.156 — how deep a vacuum you must pull before opening or disposing of an appliance, and the exceptions that let you stop at 0 psig.14 min
- 01.03Recovery and Recycling Equipment CertificationWhat makes a recovery machine legal to use, the difference between self-contained and system-dependent equipment, and the 15-pound rule.12 min
- 01.04Leak Repair Thresholds and RecordkeepingThe 20/30/10 leak rates, the 30-day repair clock, verification testing, retrofit and retirement plans, and the three-year records that prove all of it happened.15 min
02
Core — Regulation and Science
5 lessons- 02.01Ozone Depletion and the Clean Air ActWhy chlorine destroys stratospheric ozone, how the Montreal Protocol and Title VI of the Clean Air Act turned that science into US law, and the phaseout dates the exam expects you to know.14 minFree
- 02.02The Section 608 Rules, Certification Types and EnforcementThe venting prohibition, who counts as a technician, the four certification types, the refrigerant sales restriction, and how EPA enforces all of it.14 min
- 02.03Refrigerant Classification, Blends and the A2L TransitionHow EPA classifies appliances by pressure, how ASHRAE classifies refrigerants by toxicity and flammability, why blends glide, and what changes with A2L refrigerants.13 min
- 02.04Safety, PPE and Refrigerant CylindersAsphyxiation, frostbite, decomposition products, why you never pressurize with oxygen or compressed air, and the cylinder rules that Core tests hardest.13 min
- 02.05Shipping Refrigerant and Disposing of AppliancesDOT hazardous materials rules for refrigerant cylinders, and the Section 608 chain of responsibility that ends at the scrap yard.11 min
03
Type I — Small Appliances
3 lessons- 03.01What Counts as a Small Appliance, and How Much You Must RecoverThe five-pound factory-sealed definition, the equipment that Type I work actually covers, and the 80/90/four-inch recovery requirement.12 min
- 03.02Type I Recovery Techniques and EquipmentSelf-contained versus system-dependent recovery, gaining access to a sealed system, and the procedures that get the last of the charge out of a dead compressor.13 min
- 03.03Type I Safety and Appliance DisposalHandling small sealed systems safely, flammable refrigerants in domestic equipment, and the disposal chain that ends at the scrap yard.12 min
04
Type II — High Pressure
3 lessons- 04.01High-Pressure Recovery and EvacuationApplying Table 1 to real Type II equipment, vapor versus liquid versus push-pull recovery, and the isolation rules that let you evacuate only part of a system.14 min
- 04.02Leak Detection, Repair and Verification TestingThe detection methods you are expected to know, how to pressure-test safely with nitrogen, and the two verification tests the leak repair rule demands.14 min
- 04.03Servicing, Evacuation and Charging High-Pressure SystemsDeep vacuum dehydration, brazing under nitrogen, charging blends by weight, and what a compressor burnout obliges you to do.14 min
05
Type III — Low Pressure
3 lessons- 05.01Low-Pressure Recovery and EvacuationWhy 25 mm Hg absolute is the target, how to get a chiller down to it without freezing the tubes, and the right order to recover and recharge.14 min
- 05.02Purge Units, Non-Condensables and Leak TestingWhat a purge unit does, why its run time is your best leak indicator, and the 10 psig ceiling that keeps you from blowing the rupture disc.13 min
- 05.03Chiller Safety and Refrigerant HandlingExposure limits for R-11 and R-123, machinery room monitoring under ASHRAE 15, confined space entry, and handling large charges without a release.12 min
