Core taught you the rules: venting is illegal, recovery is mandatory, certification makes you legal. Type I and Type II are where the rules grow numbers. In the next four minutes you will get the map of both exam sections: what equipment belongs to each type, the recovery percentages for small appliances, the vacuum table that runs the Type II section, and the one legal reason to stop recovery early. Master the map here, then v2 drills the table until it is reflex.
MAIN
[0:30-1:30] Type I: the 5 pound world
ON-SCREEN: C14-type1-vs-type2-scope.svg, Type I column highlighted
A small appliance is hermetically sealed at the factory with 5 pounds of refrigerant or less. Both halves of that sentence are the definition: factory sealed AND 5 pounds or less. Refrigerators, window units, PTACs, dehumidifiers, vending machines, water coolers.

Recovery here is measured in percentages. With a modern certified machine, capture 90 percent of the charge if the compressor runs, 80 percent if it is dead, or pull the appliance to 4 inches of mercury vacuum. Pre-1993 machines: 80 percent across the board, or the same 4 inches. Dead compressor also changes technique: pierce both the high and the low side, because nothing inside is moving refrigerant toward your valve.
[1:30-2:15] Active versus passive recovery
ON-SCREEN: C14-system-dependent-vs-self-contained.svg
Two classes of recovery equipment. Self-contained machines have their own compressor and work on anything. System-dependent equipment has no compressor; it borrows the appliance's, and the law caps it at appliances holding 15 pounds or less. Keep your thresholds straight: 5 pounds defines a small appliance, 15 pounds caps passive recovery. The exam will swap those numbers in the answer choices and wait for you to flinch.
[2:15-3:30] Type II and the vacuum table
ON-SCREEN: C14-recovery-vacuum-table.svg, rows revealed one at a time
Type II is everything high pressure that is not a small appliance, which is nearly every system on the Island Breeze schedule. The centerpiece is this table: how deep recovery must go before you open or scrap a system. Three questions pick your cell. What refrigerant class? How big is the normal charge, above or below 200 pounds? And was the recovery machine built before or after November 15, 1993?
R-22 under 200 pounds: atmospheric, zero inches. R-22 at 200 or more: 10 inches with a modern machine. Other high-pressure refrigerants, and that includes R-410A and R-404A: 10 inches under 200 pounds, 15 at or above. Very high pressure, R-13 and R-503: atmospheric. Low-pressure chillers: 25 millimeters of mercury absolute, an absolute scale, not the gauge scale, and that distinction is a stock trap question.
[3:30-4:00] The one early exit, and the gas rule
ON-SCREEN: text overlay: Leaky appliance: stop at 0 psig. Nothing above 0.
One legal reason to stop early: the system leaks and vacuum would pull air in. Then you stop at 0 psig. Not 2 psi above to be safe. Zero. And when pressure goes back in for leak testing, it is regulated nitrogen, with a trace of refrigerant allowed for the detector. Never oxygen, never compressed air. Oxygen plus refrigerant oil under compression can explode.

Read the C14 article for the leak repair rules, the 30, 20, 10 thresholds, and the Type III chiller overview. Then watch v2, where we drill the table and walk the hardest questions in the pool. Island Breeze sends you in for Universal, so we leave nothing to guessing.
