For additional information regarding ozone depletion and air conditioning service regulations, visit EPAs website: www.epa.gov/ozone. To use a vacuum pump on an air conditioner, first, turn the pump on and open the side gauge valve, which will allow the vacuum to start pulling air out of your system. Grounded tools require a three-wire extension cord. Do not use any adapter plugs with grounded power tools. There is a sight window to see the oil level. This Vacuum Pump gets very hot when in use. The SAE 30 viscosity vacuum pump oil is also used in smaller rotary vane design pumps driven by a vee belt drive from the motor.
The warnings, precautions, and instructions discussed in this instruction manual cannot cover all possible conditions and situations that may occur. The Gauge (not included) should show negative pressure and maintain that reading for 10 minutes. In the world of mechanical oil sealed rotary vacuum pumps there is a need for a variety of oils and fluids to suit the specific type of pump, its duty and the process it is used on.This discussion covers high vacuum pumps only, such as are used in the heat treating and vacuum furnace industry. Remember to use the necessary PPE (personal protective equipment) when changing oil, and to dispose of any contaminated fluids in a safe manner. If the amount of condensed vapor is above this limit some type of condenser or cold trap should be installed on the inlet side of the pump. Most lubricating oils are paraffinic based oils that are processed to create the best product for the application. As appropriate, attach the R-12, R-22, or R-134A manifold to the AC drain port of the vehicle/appliance. This device takes the contaminated oil from the reservoir, passes it through the filter unit and then returns it to the oil piping before the oil reaches the bearings. 2 By 6 Duplex & Series, 1 By 6, and 1 By 12 Parallel, Oil Free Dry Vacuum Pumps This is not a forum to advertise or promote specific suppliers, but let me say this. Grounded tools: tools with three-prong plugs. Rotary vane vacuum pumps are available as direct drive (usually 1800 rpm) and vee belt drive (between 400 and 500 rpm) versions. Consequently, the standard vacuum pump fluid used by most gas cylinder companies was a fire retardant phosphate ester fluid. Before operating the Vacuum Pump, check the oil level as explained under Tool Set Up on page 7. Most vacuum pump oils, with low vapor pressure, are refined by specialized oil companies that can process relatively low volumes of product. Use only one Inlet Fitting at a time. wikiHow's Content Management Team carefully monitors the work from our editorial staff to ensure that each article is backed by trusted research and meets our high quality standards. Then, close it off again. Wear ANSI-approved safety goggles with side shields. It also reduces the sulphur content of the oil, which is one of the first constituents to break down in high temperature conditions. If the pump oil becomes contaminated with condensed vapor the vacuum generated will soon deteriorate due to that liquid mixed with the oil. Unmodified plugs and matching outlets will reduce risk of electric shock. Something went wrong. The vacuum level that you will measure in real work conditions will generally not be as low a pressure due to variables such as the oil condition, the position of the gauge head, the type of vacuum gauge used and the calibration of the gauge. References. The grounding prong in the plug is connected through the green wire inside the cord to the grounding system in the tool.

How often should I change the Vacuum Pump Oil? Develop the tech skills you need for work and life. You may have seen the effect of contamination by solids on the lower hinge bar of rotary piston pumps. Since then dry pumps (no fluid in the pumping volume) have been designed and perfected, but inert fluids are still used to lubricate gears and bearings that are outside the vacuum envelope of the pump. I let this sit there and run for a good hour since it was a system broken open because they stole the copper from it. http://yellowjacketuniversity.com/articles/the-evacuation-and-charge-process/, https://www.carid.com/articles/how-to-use-an-air-conditioning-manifold-gauge-set.html, https://www.2carpros.com/articles/re-charge-an-air-conditioner-system, http://www.denlorstools.com/autoblog/2012/05/car-ac-vacuum-pumps-faqs/, https://www.airconditioning-systems.com/air-conditioning-vacuum-pump.html.

Shipping costs to and from the factory are the customers responsibility. The tool must be plugged into an appropriate outlet, properly installed, and grounded in accordance with all codes and ordinances. Using other mechanical oils could impact the quality and performance of your vacuum. Before operating the Vacuum Pump, check the oil level by placing the Vacuum Pump on a flat, level surface. TO PREVENT SERIOUS INJURY FROM ACCIDENTAL OPERATION: Turn the Power Switch of the tool off and unplug the tool from its electrical outlet before performing any inspection, maintenance, or cleaning procedures.TO PREVENT SERIOUS INJURY FROM TOOL FAILURE: Do not use damaged equipment. As the distance from the supply outlet increases, you must use a heavier gauge extension cord. The oil should be at the fill line on the Oil Sight Glass. Later, when the semiconductor industry was in its infancy (1980s) most gas cylinder filling companies changed to using completely inert (inflammable) vacuum pump fluids called perfluoropolyethers (PFPE). If you are using one extension cord for more than one tool, add the nameplate amperes and use the sum to determine the required minimum cord size.

Keep the other Fitting capped while not in use. Then, shut off the pump and disconnect the hose leading into it. Allow the Vacuum Pump to completely cool before wiping down and storing indoors out of childrens reach. Going through a second distillation reduces the vapor pressure and the sulphur content even more. Some filters have a cyclone design that causes the gas flow to circulate around the filter interior so that heavy solids drop to the bottom. The vacuum will build for approximately 2 minutes before reaching full power. Avoid overfilling. That means this liquid will re-evaporate on the inlet (low pressure) side on the pump cycle and fill the pumping volume with vapor. These are called dry pumps and are the subject of another discussion. After the vacuum has run long enough, close the valve that connects to the low-side gauge and let your pump hold the vacuum for 15 minutes. (Carbon brushes or bearings, for example.).
