The disc contains data files, which will not register on a Home DVD player. Also, make sure that there is no positive charge in the system before you begin the vacuum process. Eventually, this will equalize out and give the same reading. Another contractor told me he could hook up micron gauge vacuum pump when the system is evacuated the pump had a different sound when all the air was out. You said with copper tubing, why not charging hoses? When working with tools and machines like a vacuum pump, it's always wise to wear safety goggles. A quality vacuum pump will consistently pull a deep vacuum of 50 microns or less. If the atmosphere that you are removing from the refrigeration system is moisture laden, as that moisture enters the pump it is in hook up micron gauge vacuum pump form, it is in a state of equilibrium with the air in the system. Dont laugh if the city of omaha thought they could enforce it and make money theyd be all over it! The temperature range on the does not go that low. Water can only be removed from a system in vapor form. I was wondering if the lever on the vacuum pump should be in the open or closed position during the vacuum process? Always read and comply with all warnings and instructions found in the manufacturer's manual before operating any pump. This will allow for quick oil drainage, which means you get your jobs done faster. It's important to be able to gauge how full the pump is when adding oil, so make sure your pump has an easy to read sight glass.

You can't tell for sure. Without a micron gauge pkmp do not know if the oil in the pump is clean. The oil in a vacuum pump acts as a blotter and absorbs all of the moisture and sediment in the system. As the oil becomes saturated, the efficiency of the pump is drastically reduced. Oil should be changed after every job and should only be changed when the oil is still hot. As the oil cools, the moisture separates from the oil and clings hook up micron gauge vacuum pump the metal of the pump.

Therefore, when changing the oil and not checking it with a micron gauge, you're still guessing as to whether the pump can actually pull the proper vacuum to eliminate the moisture in the system. This hook up micron gauge vacuum pump happen even if you pull on both sides of the system because there is a metering device to measure the pressure and refrigerant in the system. Air or moisture can be trapped in one side of the system and will eventually let go and therefore a higher reading on the micron gauge will occur.

Sometimes moisture can be trapped in the oil of the compressor and when it escapes it will show up in the gauge. Some manufacturers have a micron range that they want their system pulled down to, so therefore, JB can only suggest a micron reading. Our suggestion is to pull a system down to microns only if you are also pulling a vacuum on the compressor. Going below microns, you will start degassing the oil in the compressor and it will not be the same lubricating oil as it was originally.

The oil will only degass and will not suck up into the vacuum pump. Assuming that you are pulling on the high and low side of the system, did you remove the access valve cores? Leaving the cores in creates hook up micron gauge vacuum pump big restriction and causes your vaccum to take a longer time to evacuate.

The gauge ip too close to the pump and it does not have a chance to equalize in pressure. Close the blank off valve as you did before and you will see a big difference in the reading. Vacuum is critical for leaks, more so than refrigerant. Charging hoses, including environmental hoses, still permeate. Beyond permeation, where the hose ferrule is crimped to the hose, represents a potential leak under vacuum.

Quick couplers with gaskets are not a good seal. When you screw down the male flare to the gasket quick coupler, the gasket goes into several contortions and will not seal properly. JB uses O-rings on our quick couplers and as you screw down the male flare you get a metal-to-metal seat and the O-ring lays around the flare micfon give it a perfect seal. You can pull a vacuum with charging hoses, but when you want to blank off the system to check for leaks, you will need to use copper tubing or metal hoses.

Many technicians do this for ease of hook-up, but remember with this set up you are actually reading what the pump is doing and not what the pump is hook up micron gauge vacuum pump to the system. Attach a micron gauge to the male flare end, a gauge to the tee end, and a line from the tee to the pump. Turn the pump on and you will notice the side closest to the pump will be a lot lower than the other.

Eventually, phmp will equalize out and give the same reading. This will occur in a system on which you are pulling a vacuum. Technical FAQ Micron Gauges 1. I don't have a micron gauge so I leave the pump on the system for two to four hours, is this enough? If I put new oil in now and run the pump the same period of time, am I safe?

I pull only from one side of the system using a micron gauge, but at times my gauge will jump up to a gaige number. Back to top 4. I purchased a new micron gauge. How low of a vacuum should I pull? Back to top 5. It seems to take forever to pull down the gaugw I am working on. Does this mean I have a leak hook up micron gauge vacuum pump a lot of moisture in the unit?

Back to top 6. I bought a new micron gauge and I wanted to try it out with just my vacuum pump. I attached the gauge directly to the pump and it immediately went down. I then closed my blank off valve on my pump and the gauge went up very rapidly. Is the valve on gook pump leaking? Back to top 7. You said with copper tubing, why not mircon hoses?

Whether it be a Service Call to get your HVAC System Up and Vacuum Pump Hookup, Micron Level. pulling a system down into a deep vacuum. Hooking up a Micron Gauge to a Vacuum. Richard Whyte. and allow the vacuum sensor to dry for minutes gauge is attached directly to the vacuum pump or with 3' GENERAL MICRON GAUGE HOOK - UP. How can I hook it up with only a 3 hose manifold? If you have multiple ports at the vacuum pump install it there with a cap on one side of the how do you test my/your vacuum set up?.
