What is 50 microns
Action taken once a possible leak has been located.
What is perform bubble test.
One of two methods used to recover refrigerant from a system with less than 15 pounds of refrigerant.
What is passive.

A vacuum pump is used on a refrigeration system for this reason.
What is contaminants and moisture.
Gas used to perform pressure test in refrigeration system.
What is Nitrogen
How can the recovery process be sped up.
What is submerge the tank in container of ice.
Which side of the system is the blue hose connected to.
What is low-side
High voltage components controlled by switches and control sequence that perform the work.

What is mechanical compound gauge.
The Y terminal on the thermostat controls what process on an air conditioning system.
What is Cooling
The first step when beginning the evacuation process.
What is disconnect power to system compressor.
The reason bubble solution is used instead of soap and water.
What is non-corrosive
Tool used to prevent liquid slugging when using recovered refrigerant.
What is a vaporizer.
The best location to measure the low pressure region.
What is after the evaporator
The green wire on a thermostat controls what component.
What is fan or blower
The tool used to prepare a recovery tank to decrease the pressure below atmospheric pressure.
What is a vacuum pump
A leak detector that uses sound instead of a sniffer.
What is ultrasonic leak detector.
The minimum process before refrigerant is reused from a leaking system.
What is recycling.
The action to prevent liquid refrigerant from entering the compressor when using manifold gauges.
What is close both the high and low side valves
