Recovery & RecyclingCâu 225 / 240
For a small appliance recovered with equipment made after November 15, 1993 while its compressor runs, the required recovery is:
a.90 percent of the charge
b.80 percent of the charge
c.70 percent of the charge
d.25 mm Hg absolute
Giải thích
With post-1993 recovery equipment and a working compressor, a small appliance requires 90 percent recovery; if the compressor does not run, the requirement is 80 percent. The 4 in Hg vacuum is an accepted alternative for such equipment, and 25 mm Hg absolute applies to low-pressure appliances, not small ones.
