What refrigerant is ozone friendly

HFC-134A

What refrigerant is ozone friendly

HFC-134a

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

It extracts the refrigerant from the vehicle and cleans it on site

The recover equipment does what

It extracts the refrigerant into an approved container for the refrigerant to be sent off for reclamation

What happened on July 1 1992

It is illegal to vent

Section 609 of sales restrictions does what

It prohibited the sale of small small cans of ozone depleting refrigerants to anyone other than certified technicians

When was it illegal to vent class 1 and class 2 refrigerants into the atmosphere

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

Meet the the UL standard

Oils can not be

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

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
