Type I — Small AppliancesQuestion 120 of 240
A technician plans to recover from a chest freezer whose compressor is seized (inoperable). Which combination correctly describes the required equipment and recovery level?
a.Passive equipment; 90% recovery
b.Any equipment; 100% recovery
c.Self-contained (active) equipment; 80% or 4 inches Hg
d.Self-contained equipment; 4 inches Hg above atmospheric
Explanation
With a seized, inoperable compressor, the appliance cannot help move refrigerant, so self-contained (active) recovery equipment is needed and the required level is 80% recovery or 4 inches Hg vacuum. The 90% level applies only when the compressor operates. No method requires 100% recovery, and 4 inches Hg above atmospheric is not a vacuum.
