When brazing or exposing refrigerants to open flames or red hot metal,

• R-12 and R-22 can form a phosgene gas.

• R-12 and R-22 can form hydrochloric and hydroflouric acids

• ensure you are in a well ventilated area.

• All of the above

When using system dependent (passive) recovery, the EPA requires

• 80% of the refrigerant to be removed if the compressor is operating

• 80% of the refrigerant to be removed if the compressor is not operating.

• 90% of the refrigerant to be removed if the compressor is not operating

• 70% of the refrigerant to be removed if the compressor is operating

Which of the following refrigerants must be recovered with a current recovery system?

• R-12 CFC

• R-502 azeotrope

• R-717 ammonia

• R-22 HCFC

While recovering refrigerant, why is it necessary to install a piercing valve on both the high and the low side of a small appliance that has an inoperative compressor?

• It will help drain the oil out of the system while recovering the refrigerant.

• It will help decrease the rate of refrigerant evaporating

• It is just a waste of time and is not necessary at all

• It will decrease the time of the refrigerant recovery

EPA defines a Major Repair as

• replacing a compressor

• replacing a condenser

• replacing an evaporator

• all of the above

• 10 pounds

• 15 pounds

• 20 pounds

Which of the following is a requirement for a Type I Technician when servicing small appliances?

• Must recover 80% of refrigerant if the compressor is operational

• Must recover 90% of refrigerant if the compressor is operational

• Must recover 70% of refrigerant if the compressor is operational

• Must recover 60% of refrigerant if the compressor is operational
