Evacuation Procedure - HVAC Know It All

Nov 25, 2017 · Use the reading on the micron gauge to determine when a proper vacuum has been achieved. It is common within the industry to set a vacuum target of 500 microns. 8. Once the target vacuum has been achieved, isolate the system from the pump and observe the micron gauge reading. A common term for this procedure is called a "decay test".

Refrigerant Evacuation: Don't Be a Clockwatcher .

To do this, we need to attach an electronic micron gauge to the system to measure the vacuum level between 29 to 30 in. of mercury. The scale of the electronic gauge ranges from 0 to 5,000 microns. As we continue to extract vapor from the system with a vacuum pump, the decrease in pressure will register on the micron gauge.

Micron Gauge

Sep 13, 2008 · But today, time is too precious to risk even a small number of issues. So the micron gauge is the only way to go. Most guys will use it for all work involving any opening of the refrigeratioin side of the system. And a good tech plans his work so he's not standing around watching the vacuum pump pull the system down.

Understanding Vacuum Measurement Units

In some industries, electronic vacuum gauges are used that read in microns, for example from 1000 down to 0 microns which would be the same as from 1 down to 0 mm Hg. (See Fig. 4) In the 1970s scientists decided that they did not want to measure low pressures in linear measurements such as microns and millimeters.

Evacuation Of Moisture In Your HVAC System | Behler-Young

Vacuum Test. Once you have achieved a 500 micron or lower vacuum, isolate the system from the service hoses, manifold and vacuum pump at the evacuation tool valves or hose ball valves. Vacuum should stabilize and hold below 500 microns. If the vacuum rises slowly and stops, there is moisture in the system, and evacuation should be continued.

What is a Micron? - HVAC School

Jul 25, 2018 · 1 inch of mercury (HG) is equal to 25,400 microns (of mercury) In the micron vacuum scale, we start at 760,000 microns at sea level atmospheric pressure and work down towards a perfect vacuum of 0 microns or 0 hg. This is why a lower # in the micron vacuum scale equals a better / deeper vacuum, a higher number equals a worse / less deep vacuum.


Connecting a vacuum pump to a pressurized line can damage the pump and vent refrigerant to the atmosphere – which is against the law. • A properly evacuated system must be at 2500 microns or less – impossible to detect without an electronic vacuum gauge. (69060, 69070, 69075 etc.) • Micron gauges (electronic vacuum
