Type I — Small AppliancesQuestion 107 of 240
When a small appliance's compressor is operable, why does the rule require a higher recovery level (90%) than when it is inoperable (80%)?
a.Because the appliance must be recharged afterward
b.Because HFCs recover faster than CFCs
c.A running compressor can pump more out
d.Because operable compressors always hold less oil
Explanation
A working compressor actively pumps refrigerant toward the recovery equipment, so more of the charge can realistically be removed, and the rule sets the higher 90% target. When the compressor cannot run, recovery is harder, so the standard is 80%. The rule scales the requirement to what is practically achievable.
