Which certification covers both jobs?

Recovery requirements · EPA 608 Type I. The correct answer, and the reasoning behind it.

The small-appliance definition and the recovery levels required.

The question

A technician services a 1.8-pound vending machine and also a 30-pound rooftop unit. Which certification covers both jobs?

• AType I alone, because both use high-pressure refrigerant
• BType I plus Type II, or UniversalCorrect answer
• CType II alone, because it covers all high-pressure equipment
• DType III, because it covers all commercial equipment

Why “Type I plus Type II, or Universal” is correct

Type I covers small appliances, and Type II covers medium-, high- and very high-pressure appliances other than small appliances. A technician working on both needs both types, or Universal, which covers all appliances.

Why the other answers are wrong

• Type I alone, because both use high-pressure refrigerant — Type I covers only small appliances; the 30-pound unit is outside that.
• Type II alone, because it covers all high-pressure equipment — Type II covers appliances except small appliances, so it does not cover the vending machine.
• Type III, because it covers all commercial equipment — Type III covers low-pressure appliances, not these units.
