During the entire recovery operation
What is a reason to obtain an accurate pressure reading of refrigerant inside a recovery cylinder?
Damaged refrigerant
When is it essential to take measures to help release refrigerant from the compressor oil during refrigerant recovery?
It is essential to take measures to help release refrigerant from the compressor oil during refrigerant recovery when the refrigerant release valve is stuck closed. The release valve should be maintained at all times.
What would the result be if a recovery cylinder were filled with liquid refrigerant and allowed to warm up?
The result of filling a recovery cylinder with iquid refrigerant and allowing it to warm up is that the heat of the container would warm the refrigerant inside of it. The refrigerant would, as a result expand.
How do you depressurize car ac?
A refrigerant recovery machine is required.
what condition can cause excessive pressure conditions on the high side of a self contained active recovery device?
When there is a large volume of non-condensable gas in the refrigerant being recovered.
When a pungent odor is detected during a sealed system recovery?
It is the characteristic smell of the refrigerant.
All devices used for refrigerant recovery must?
All devices used for refrigerant recovery must be certified by the EPA. If the device was manufactured before November, 1993, It must be capable of recovering 80% of the refrigerant in the appliance. If the device was manufactured after this date, it must be capable of recovering 90% of the refrigerant.

Which refrigeration systems or appliances would be permissible to use a passive recovery device for refrigerant recovery?
demestoic refigerator
How do you recover refrigerant?
This is most definitely not a DIY task. To do it properly, you need to first test the purity of the refrigerant, which takes special equipment to do, as does actual recovery and storage of the refrigerant.
