Type I — Small AppliancesQuestion 113 of 240
A technician's self-contained recovery machine is labeled as certified for small-appliance recovery. What performance does that certification confirm it can meet?
a.Pulling 500 microns for deep dehydration
b.90% (running) or 80% (not), or 4 in Hg
c.Reaching 25 mm Hg absolute on low-pressure chillers
d.Recovering 100% of the refrigerant every time
Explanation
A recovery machine certified for small appliances is verified to reach the required 90% (compressor operating) or 80% (compressor not operating) recovery, or the 4 inches Hg vacuum alternative. No equipment is required to recover 100% of the charge. Deep-vacuum micron levels apply to evacuation and dehydration on larger systems, not to the small-appliance recovery standard.
