The required evacuation level for recovery depends on:
a.Only the technician's certification type
b.Only the ambient temperature

Giải thích
The recovery evacuation table sets required levels based on the appliance type and size and whether the recovery equipment was made before or after November 15, 1993. For example, low-pressure appliances require 25 mm Hg absolute, while a large HCFC-22 system requires 10 in Hg with newer equipment. Certification type and cylinder color do not set the vacuum level.
