Product Highlights
- Easy monitoring & cooling: with an oil viewing window, this ac vacuum pump can easily monitor oil levels to avoid oil deficiency. our vacuum pump tool can cool itself and prevent itself from burning out. the built-in thermal protection prevents the machine from burning and extend the machine's life.
- Backflow prevention: the refrigerant vacuum pump avoids chamber contamination by preventing oil from flowing back, otherwise polluting its container and tubes. 1/4" oil fill port makes oil adding simpler since the port is accessible from the front or either side. oil drain hole makes oil drain faster, and the gas exhaust port can efficiently avoid oil spout.
- Heavy duty vacuum pump: fad: 10 cfm, dual stages; power: 1 hp; ultimate vacuum: 0.3 pa. our hvac vacuum pump comprises heavy-duty aluminum alloy with durability and sturdiness. the strong copper motor provides continuous power, and a shock-proof base supports the stable operation.
- Wide application: the vacuum pump is widely used for commercial and household applications, suitable for cleaning a household air conditioner, automobile maintenance, vacuum packaging, refrigerator vacuum, industry, etc.
- Ergonomic grip handle: the ergonomic grip handle is designed for superior comfort and portability. with the convenient handle, you can easily carry the vacuum pump to its destination.

- And add oil until oil just shows in the bottom of the sight glass. 3) replace the exhaust fitting cap and remove the cap from one of the inlet ports. turn the motor switch to on. when the pump runs smoothly, replace the cap on the inlet port. this way take from two to 30 seconds depending on the ambient temperature. after the pump runs for approximately one minute check...
- To shut down your pump after use; 1) close the manifold valve between the pump and the system. 2) remove the hose from the pump inlet. 3) cap the inlet port to prevent any contamination or loose particles from entering the port.
- Before using your vacuum pump; 1) check to be sure the voltage and frequency at the outlet match the specifications on the pump motor decal. check the on-off switch to be sure it is in the off position before you plug the pump into an outlet. remove and discard the exhaust cap from the end of the pump's handle. 2) the pump is shipped without in the reservoir. before sta...
- The level should be even with the sight glass oil level line. add oil necessary. note: when the pump is running, the oil level should be even with the line on the sight glass. under filling will result in poor vacuum performance. over filling can result in oil bloeing from the exhaust.
- Troubleshooting guide; 1) failure to start; check the line voltage. the pump need to start at +/-10% line volatge at 32ºf. at extremes, switching between the startand run windings may occur. 2) oil leakage; be sure the oil is not a redidual accumulation from spillage, etc. if leakage exists the module cover gasket or the shaft seal may need replacing. if leakage exists ...
