Type I — Small AppliancesQuestion 99 of 240
A vending machine repair company sends technicians to recover refrigerant from beverage coolers in the field. These sealed factory-charged coolers hold about 2 pounds of R-134a. Under Section 608 they are treated as:
a.Type II high-pressure appliances requiring 10 inches Hg vacuum
b.Small appliances subject to the 80%/90% (or 4 inches Hg) recovery rules
c.Low-pressure appliances requiring 25 mm Hg absolute
d.Motor vehicle air conditioners under Section 609
Explanation
Factory-sealed beverage vending machines and coolers holding five pounds or less of refrigerant are small appliances. Recovery must reach 80% (compressor off) or 90% (compressor on), or the alternative of 4 inches Hg vacuum. They are not Type II, Type III, or motor vehicle appliances.
