A small appliance is defined by EPA as; Appliances manufactured, charged, and hermetically sealed in a factory with 5 Lbs or less of refrigerant 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
And exempt refrigerant is any refrigerant that has a 0 Ozone depletion potential (0 ODP) any global warming potential (GWP) equal to or lower than carbon dioxide, that is a GWP of _________ or less. 1 What is not a small appliance? An MVAC-like system that holds 3 pounds of R- 22 Any system with a charger less than ________ pounds can you system dependent recovery equipment. 15 Anytime pressurized nitrogen is put into the system, the nitrogen gas Maybe vented to the ambient air When a tank of mixed refrigerant is sent to a reclaimer, they can Either refuse to except the refrigerant or charge extra for processing it
A passive system dependent recovery process Recovered refrigerant in a non-pressurized container What is the pressure of a storage cylinder of R-134A, that is stored in a room where the temperature is 100°F? 124 PSIG What is the pressure of a storage cylinder of R-404A, that is stored in a room where the temperature is 100°F? 237 psig Any refrigerant that is vented off the top of the charging cylinder Must be recovered Recovery of refrigerant cannot begin if the initial pressure in the system is 0 psig
A very large refrigerant leak can cause Suffocation because refrigerants Are heavier than air and displace oxygen Always _____________ when connecting or disconnecting refrigeration hoses. 1.) wear safety eyewear and butyl-lined gloves 2.) verify the hoses are rated for the refrigerant being used 3.) avoid trapping liquid refrigerant in the hoses CFC and HCFC refrigerants can decompose to form Hydrochloric and hydrofluoric acids Applying heat, with a heat gun, to the compressor; Can help vaporize any trapped liquid refrigerant during recovery. Which HC refrigerant is allowed for use in new domestic small appliances? R-600a
Technicians who perform sealed system service on small points is must have Type 1 or universal certification Recovering multiple types of refrigerant in the same cylinder; Will make the reclaimed refrigerants unreclaimable Type one certification is required for; Persons handling refrigerant during maintenance, service, or repair of small appliances. The sale of reclaimed CFC, HCFC, HFC, and HFO refrigerants is_______. Restricted to technicians who are EPA certified and refrigerant recovery A small Pliance is defined as a system that is Manufactured, fully charged, and hermetically sealed in a factory with a charge of 5 pounds or less
The refrigerant vapor that is vented off the top of the cylinder must be recovered. Which of the following is true regarding refrigerant leaks one small appliances? EPA does not require repair, but leaks should be repaired whenever possible. If a strong odor is detected while performing a refrigerant recovery process, A compressor burnout has likely occurred. Small appliances are equipped with a straight piece of tubing (process stub) that is used; As the installation location for piercing type access valve System dependent or passive recovery equipment ; Captures refrigerant into a non-pressurized container.
When pressurizing the system with nitrogen you should; Charge through a pressure regulator and install a relief valve in the line downstream from the pressure regulator. On a system with an operating compressor, recovery equipment must be capable of recovering; 90% refrigerant or achieving 4 inches of vacuum With a non-operating system compressor, recovery equipment must be capable of recovering; 80 % of the refrigerant or achieving 4 inches of vacuum Which of the following is an example of a noncondensible? Air When the system is in deep vacuum; Never energize the compressor
If regulations change after the technician become certified; The technician is responsible for complying with any changes to the regulations When using a system dependent recovery system on an appliance that has an operating compressor, the technician should; Run the compressor and recover from the high side of the system only. Small appliances in recreational vehicles may use refrigerants such as ammonia, hydrogen, and water. These refrigerants; Should not be recovered 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.
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:
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. nonflammable compressed gasses number of cylinders of each type of gas
