A different way to learn

What changes when the number sits next to the equipment

The same topic, explained two ways.

A text manual

Owners or operators of appliances normally containing 50 or more pounds of ozone-depleting refrigerant must repair leaks within 30 days when the leak rate exceeds 30 percent for industrial process refrigeration, 20 percent for commercial refrigeration, or 10 percent for comfort cooling appliances. Initial and follow-up verification tests must be performed to confirm the repair. If the leak rate cannot be brought below the applicable threshold, the owner or operator must develop a retrofit or retirement plan for the appliance.

A text manual

You hunt for one number inside three pages of regulation text.
You memorize 10, 20 and 30% as a list and forget which system goes with which.
You ask on a forum and get three answers, one of them from before the rule changed.

UV frees one chlorine atom from a CFC, and it can destroy over 100,000 ozone molecules. — **This book**
The number sits in a box next to the equipment it applies to.
Each threshold is drawn on its own system: comfort cooling, commercial refrigeration, industrial process.
Each rule is cited to 40 CFR Part 82 Subpart F and stated per the current rule.

Inside

A Dead Window Unit, Your Gauges, and a Question About the Refrigerant

You're on a service call. The customer's window unit has a dead compressor and the refrigerant is still in the circuit: what are you allowed to do with it?

The EPA manual answers in paragraphs: the venting ban, the types of appliance, the recovery requirements. You read it, you nod, and you still don't know what applies to the unit in front of you.

In the book, the small appliance is one page: a window unit drawn with its recovery requirement beside it. The compressor decides which number applies: 80%, 90% or 4 in Hg.

The rest works the same way: the refrigeration cycle, recover, recycle and reclaim, what counts as a small appliance, the numbers people mix up. Each one has its own page.

You look at the unit, find the page and do the job right, without rereading the whole rule.

Compressor, condenser, metering device, evaporator: high side in red, low side in blue.

Real pages

A look inside the pages

One big drawing per page, with a box of what to remember.

Core + Type I + Type II + Type III = Universal; 70% to pass, section by section.

Recover stores it, recycle cleans it, reclaim brings it to AHRI 700 purity.

Small appliance = factory-made, factory-charged, hermetically sealed, 5 lb of refrigerant or less.

Medium 45–170 psia, high 170–355 psia, very high above 355 psia: all Type II.

Low-pressure appliance: liquid saturation pressure below 45 psia at 104 °F (R-11, R-123).

15 psig disc, 10 psig test, 80% fill, 10/20/30%, 30 days, 3 years, 125%

These are real pages from the book. The table of contents is the full one: 8 parts and 63 topics.

5
Type I: Small Appliances
What counts as a small appliance, the 80%, 90% or 4 in Hg requirement, passive recovery, piercing valves, R-600a and R-290, and safe disposal records.
6
Type II: High-Pressure Systems
Pressure ranges in Type II, required evacuation levels, recovering liquid first, major vs minor repair, finding leaks, the 10, 20 and 30% thresholds, the 30-day repair and the HFC rule.
7
Type III: Low-Pressure Chillers
What a low-pressure appliance is, why leaks go in, the purge unit, the 15 psig rupture disc, the 10 psig leak test, recovery to 25 mm Hg, vapor-first charging and draining oil.

Final Review
Numbers that get mixed up, the three Types side by side, colors and labels, pairs that look alike, the most frequent mistakes in the answers and a checklist.

Easy to mix up

Spot the mistake before it costs you

Every page ends with the mix-up that trips people up.

p. 11 · HOW CHLORINE EATS OZONEEASY TO MIX UP

Ozone damage comes from chlorine, not fluorine. That's why chlorine-free HFCs have zero ODP.

p. 27 · RECOVER, RECYCLE, RECLAIMEASY TO MIX UP

Refrigerant that changes owners must be reclaimed. Recycled refrigerant stays with the same owner's equipment.

Who it's for

Is it for you?

Pick the one that sounds like you.

You're just getting started

You start from the cycle itself: four components on one loop, high side in red, low side in blue. Every rule after that hangs on a system you can already picture.

You already do the work, but the rules are fuzzy

You've hooked up gauges for years; the book puts the regulation next to what you already do, like the 80%, 90% or 4 in Hg recovery levels drawn on a small appliance.

You're adding another Type

Whether it's your first Type or one more, the final review lays out the numbers that get mixed up and the three Types side by side.

Questions

What people ask most

Quick answers before you decide.

Is it for me if I've never used a gauge set, or if I've worked with refrigerant for years?

Both. It starts from the cycle on one loop, with the high side in red and the low side in blue, and then ties each rule to the equipment it covers. If you already do the work, the book puts the regulation next to what you already do.

How do I get the book?

The book and both gifts arrive as PDFs by email.

Is it a one-time payment?

Yes. You pay once and the PDFs are yours, with no subscription.

Does it replace a course or the certification itself?

No. It's illustrated study material, not an official EPA publication. The EPA 608 certification comes from an EPA-approved certifying organization, and the book doesn't replace hands-on training.

Where does the content come from?

From 40 CFR Part 82 Subpart F, the EPA Section 608 technician certification materials, the AIM Act HFC rules (40 CFR Part 84) and ASHRAE Standard 34. Every critical number is cited to one of them.

Is it up to date with the leak rules and A2L refrigerants?

Yes. The leak rate pages follow 40 CFR Part 82 Subpart F as it reads today, and there are separate pages on the AIM Act rule for HFC systems (40 CFR Part 84) and on handling A2L refrigerants like R-32. Each critical number names the section it comes from, so you can check it against the eCFR yourself.

I already have the manual and free videos. What does this add?

Each rule sits on one page with a drawing of the equipment it applies to and a note box with what's easy to mix up. It works alongside the manual, not instead of it.

Can I print it and keep it in the truck?

Yes. It's a PDF, so you can print the whole book or just the pages you need.

How does the refund work?

You have 30 days. We refund everything if the file won't open, if the book isn't what you see on this page, if you were charged twice or if the email doesn't arrive: just email us.

It's a PDF: read it on screen or print it
