What this covers

Sample questions

A technician who holds only Type I certification is asked to recover the refrigerant from a 3-ton residential split system. The technician

  1. may do the work, because the charge is under 15 lb
  2. may do the work if a self-contained machine is used
  3. may not do the work, because it requires Type II certification
  4. may not do the work, because it requires Type III certification
Show the answer

C. may not do the work, because it requires Type II certification

A split system is not a small appliance, so Type I does not cover it; R-22 and R-410A split systems are high-pressure appliances under Type II. The size of the charge alone does not make something a small appliance.

Reference: 40 CFR 82.161

Using recovery equipment made after November 15, 1993 on a small appliance whose compressor does NOT run, a technician must recover at least what share of the refrigerant?

  1. 60 percent
  2. 80 percent
  3. 90 percent
  4. 95 percent
Show the answer

B. 80 percent

Without a working compressor less refrigerant can be moved, so the requirement drops to 80 percent. The 90 percent figure applies only when the appliance compressor is operating.

Reference: 40 CFR 82.156(b)

Instead of recovering a set percentage of the charge, a technician may meet the small appliance requirement by evacuating the appliance to

  1. 0 in. Hg vacuum
  2. 4 in. Hg vacuum
  3. 10 in. Hg vacuum
  4. 15 in. Hg vacuum
Show the answer

B. 4 in. Hg vacuum

Pulling the appliance to 4 inches of mercury vacuum satisfies the rule and is the practical test, since the percentage recovered is hard to measure. The 10 and 15 inch levels belong to larger appliances.
