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
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
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
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
If a large leak of refrigerant occurs in an enclosed area 7 no self-contained breathing apparatus is
available then you should - ANSWER-Vacate & ventilate the spill area
Portable refillable tanks or containers used to ship recovered refrigerants must meet what standards -
ANSWER-DOT
Recovery or recycling equipment whaich was manufactured after 11-15-93 and is used to recover
refrigerant from small appliances prior to the disposal of the small appliance must be used: - ANSWER-
recover 80% of the refrigerant if the compressor isn;t working and 90% on one with a working
compressor
EPA regulations require the capture of at least 80% of the refrigerant from a small appliance with an non
operating compressor is the tech is using: - ANSWER-either type of recovery unit
A standard vacuum pump designed for evacuation & dehydration can: - ANSWER-be only used as a
recovery device in combination with a non pressurized container
