EPA 608 Type 1 Questions and Answers 100% Pass 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 The EPA section 608 certification must be renewed every 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 small appliances The sale od CFC & HCFC refrigerants is: 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: 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: it can help speed of recovery and required recovery effiency If you install an access fitting into a sealed system: the fitting should be leak tested before proceeding with recovery Before beginning a refrigerant recovery procedure it is alway necessary to: determine the type of refrigerant in the system when recovering refrigerant into a non-pressurized container from a refrigerator with an improper compressor: 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? 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: 300 psig. When using ______, it is essential to take extra measures (heating/striking), to help release trapped refrigerant from the compressor oil. 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? 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 1 valve on the high side Which refrigerant is most commonly used as a replacement for R-12 in new household refrigerators R-134a Small amounts of refrigerant have no odor, therefor a pungent odor is detected during a system recovery &/or repair: a compressor burn-out has likely occurred If R-22 or R-12are exposed to high temperatures, these refrigerants can decompose to form: hydrochloric & hydroflouric acids Large spills of refrigerant can cause suffocation because: they are heavier than air & displace oxygen In the event of a large release of R-12 or R-22 in a contained area 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 Vacate & ventilate the spill area Portable refillable tanks or containers used to ship recovered refrigerants must meet what standards 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: 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: either type of recovery unit A standard vacuum pump designed for evacuation & dehydration can: be only used as a recovery device in combination with a non pressurized container If you are recovering refrigerant from a frost free refrigirator you should: turn on the defrost heater to vaporize any trapped liquid Solderless piercing valves should not remain installed on refrigeration systems after completion of repairs because: they can leak over time A refrigerant that can be used as a direct service drop in subsitute for R-12 in a small appliance is: NONE When connecting your service manifold to check your system pressures it is always a good idea to: use equipment such as hand valves or seld sealing hoses to minimize release A recovery cylinder which is 1/2 full of recovered R-22 at normal room temperature about 75, in the absence of non-condensables, will be pressurized to: 75 psig A passive system-dependent recovery device for small appliances: captures refrigerant in a non-pressurized container When transporting refrigerants, the DOT regulation number 49 CFR requires________to be recorded on the shipping papers for hazard class 2.2 nonflammable compressed gasses number of cylinders of each type of gas
