HFC stands for?
Hydro florine carbon
PAG's are
Hygroscopic, which means they draw water from there atmosphere when exposed
Step 5 of retrofitting
If the system includes an pressure release device the technician must install a high pressure compressor shut off switch to prevent the compressor from increasing pressure until the refrigerant is vented
Step 4 of retrofitting
If you are retrofitting a vehicle that contains R-22 you must ensure that you only use barrier hoses
The recover/recycle equipment does what

July 1 1992
SNAP was in effect on
March 18 1994
Under the SNAP rule each new refrigerant must
Meet and comply with all epa regulations and requirements
Recycling equipment must

Mixed
Mvac stands for
Motor vehicle air conditioner
What is topping off?
New refrigerant on top of an old refrigerant
If you are certified to handle all refrigerants do you need to be recertified
No
As of November 15 1995
No alternate refrigerants including HFCs will be vented into the atmosphere
Section 608 of the sales restrictions went in effect on
November 14 1994
What day was it illegal to vent HFCs into the atmosphere
November 15 1995
Unique fittings must be
Permanently attached to the end of the hoses that attach to mvac systems and recovery and recycling equipment
What happened in November of 1990?
President bush signed the clean air act
What is the purpose of the compressor shutoff switch
Prevent the compressor from increasing the pressure to the point where the refrigerant is vented
To reclaim is to
Process the refrigerant to a level equal to new product specifications as determined by chemical analysis
Service shops also has to make sure every person using the equipment is
Properly trained and certified
ozone layer
Protective layer in atmosphere that shields earth from UV radiation and helps maintain stable earth temperature
Which refrigerant is the most harmful to the ozone layer
R-12 CFC or CFC's
Which refrigerant is most commonly used as a replacement for R-12 in new household refrigerators

Recover, Recycle, Reclaim
HFCs are primarily used for
Refrigeration and air conditioning
The Montreal protocol was to
Regulate the production of chlorofluorocarbons, halons, and hydrochlorofluorocarbons
Montreal Protocol does what
Regulates the phase out production and use of CFC and hfc
What is ozone depletion?
Release of refrigerants into the atmosphere
To remove the original refrigerant you must
Remove the original CFC-12 from the system prior to charging with the new refrigerant doing this will prevent the contamination of one refrigerant with another
To recover is to
Remove the refrigerant and store it in a approved external container
The sale of any size container of CFC-12 to anyone other than a certified technician was prohibited under what
