certified by an EPA approved lab if the recovery equipment was made after -
ANSWER: November 15, 1993
Recovery devices made before 11-15-93 and are used for recovery of refrigerant
from small appliances must be capable of: - ANSWER: 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: - ANSWER: a device
manufactored, charges & hermeticly sealed in factory with a charge of 5lbs or less

during the maintenance or repair of: - ANSWER: 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 - ANSWER: a straight piece of tubing,
called a process tube that is entered using a piercing valve
,2|Pag e
The EPA section 608 certification must be renewed every - ANSWER: never
It is an EPS regulation that any person who opens and appliance for maintenance,
service or repair must have at least one self-contained recovery machine avalible at
their place of buisiness. The only exception to this rule are persons working on -
ANSWER: small appliances
The sale od CFC & HCFC refrigerants is: - ANSWER: restricted to techs who are
EPA certified in refrigerant recovery
Anyone who recovers refrigeration during maintenance, service or repair of small
appliances must be certified as either a universal Tech or a: - ANSWER: Type 1
tech
When recovering refrigerant from a household refrigerator who's compressor does
not run, it is recommended that a low and high side access valves be installed
because: - ANSWER: it can help speed of recovery and required recovery effiency
If you install an access fitting into a sealed system: - ANSWER: the fitting should
be leak tested before proceeding with recovery
,3|Pag e
Before beginning a refrigerant recovery procedure it is alway necessary to: -
ANSWER: determine the type of refrigerant in the system
when recovering refrigerant into a non-pressurized container from a refrigerator
with an improper compressor: - ANSWER: it is necessary to heat & strike the
compressor with a rubber mallet
When checking for the existence of noncondensable gases inside a recovery
cyclinder, why is it proper procedure to allow the temperature of the cyclinder to
stabilize @ room temperature before taking a pressure reading? - ANSWER: any
comparisons to a pressure-temperature chart is only valid if both the pressure &
temperature of the refrigerant are stable
A recovery cyclinder which is 1/2 full of recovered R-410A @ 90*F, in the
absence of non-condensables will be presurized to: - ANSWER: 300 psig.
When using , it is essential to take extra measures (heating/striking), to help
release trapped refrigerant from the compressor oil. - ANSWER: passive system-
dependdent recovery devices on a small appliance with a non-operating
compressor.
According to the EPA which recovery equipment maintenance practice(s) should
be preformed on a regular basis? - ANSWER: check recovery device for
refrigerant leaks
, 4|Pag e
On a small appliance with an operating compressor that has a completely plugged
capillary tube, what is the minimum number of access valves that are needed to
evacuate the refrigerant - ANSWER: 1 valve on the high side
Which refrigerant is most commonly used as a replacement for R-12 in new
household refrigerators - ANSWER: R-134a
Small amounts of refrigerant have no odor, therefor a pungent odor is detected
during a system recovery &/or repair: - ANSWER: a compressor burn-out has
likely occurred
If R-22 or R-12are exposed to high temperatures, these refrigerants can decompose
to form: - ANSWER: hydrochloric & hydroflouric acids
Large spills of refrigerant can cause suffocation because: - ANSWER: they are
heavier than air & displace oxygen
In the event of a large release of R-12 or R-22 in a contained area - ANSWER:
you should wear a "SCBA" or leave the area is required
