, Recovery equipemnt used for the service or repair of small appliances must be certified
by an EPA approved lab if the recovery equipment was made after
November 15, 1993
Recovery devices made before 11-15-93 and are used for recovery of refrigerant
from small appliances must be capable of:
recovering 80% of the refrigerant whether or not the compressor is operating or
achieving a 4 inch vacuum under conditions of ARI 740-1993
EPA's definition of a small appliance includes:
a device manufactored, charges & hermeticly sealed in factory with a charge of 5lbs or
less
Tech's with a type 1 small appliance certification are certified to recover refrigerant during
the maintenance or repair of:
PTAC's with 5lbs or less of refrigerant
EPA requires that all small appliances be equipped with a service aperture or other device
that is used when adding or removing refrigerant from the appliance. For small
appliances this service port typically
a straight piece of tubing, called a process tube that is entered using a piercing valve
