But first thing first.

What Is A Vacuum Pump

Vacuum pumps are electronic devices that help pull out air and gas from a closed area, leaving a partial vacuum. The primary purpose is to clean. It comes in two different types (dry and wet) depending on the need.

How To Use Vacuum Pump

Hooking up a vacuum pump is an essential part of cleaning ACs and other air conditioning devices. Below are some steps that would help you master this.

  • Positioning Up Your Vacuum Pump

When you start using your vacuum pump, make sure it is filled with clean vacuum pump oil.

Open the oil fill cap, pour in the oil until it reaches the oil fill line marked on the inside. Then close the oil cap.

  • Connect The Gauges To Port

You will need a gauge set that supports your vacuum and the pressure ports. Mainly there are two ports (Low-pressure ports and High-pressure ports). The blue gauge supports low pressure, while the red one supports high pressure. At the same time, the yellow hose will connect your gauge to the vacuum.

  • Opening Up The Valves

After placing the gauges, you will need the valves on your device to be open and close the device’s service port.

  • Start Your Pump

As soon as you are done connecting everything, use the switch to turn it on. You will hear the vacuum pump turning on.

  • Open The Side Gauge Valve

Once the vacuum pump is on, you will need to open the gauge valve placed on the sides of each gauge. This will help the air out.

  • Let It Run For 15 Mins

Once the vacuum pump is on, let it run at full speed for at least 15 minutes to a max of 30 minutes. This will also help to pull out the air completely.

  • Closing Your Vacuum

You need to close the low side valve and let the vacuum hold for 15 mins. After it has been turned on for enough time, close the valve that connects on the low side of the gauge.

  • Close The Vacuum Pump

After turning it on for a sufficient amount of time, you need to close the same switch to turn it off, which you used to turn it on. Let the vacuum completely disconnect before you close the system.

  • Detach Your Vacuum

Finally, your vacuum is fully detached. Now you can take off the hose connected to the pump. Your device should be fully assessed by this time and all read to be used.

Do’s and Don’ts Of Hooking Up the Vacuum

  • Make sure you are using oil-sealed vacuum pumps.
  • Don’t use the vacuum pump if the oil is polluted with other chemicals or solvents.
  • Change oil begore using. Contaminated oil will block the oil mist filter.

Tips Of Hooking Up the Vacuum

  • Make sure to use only vacuum pumps oil. Do not use any other oil to fill in the oil caps to ensure longer life of vacuums.
  • The gauges and hoses should be connected correctly.
  • Make sure to check both the ports, high pressure, and low pressure.
  • When the valves are closed, there should be little to no pressure.
  • If you are using the pump in cold weather, open the intake ports for full speed. Later close them.
  • Let it run for enough time to get the correct measurement.
  • If the valves do not hold up for a longer time, there might be leakage.
  • Replace the components immediately on the pump.
  • Control the pressure.
  • Broken belts, electrical problems inside the unit, or hoses will cause vacuum pump failure.

Conclusion

No doubt vacuum pumps are not easy to deal with, but once you master the technique of hooking it up correctly, it won’t be time-consuming. Make sure to handle the vacuum pump and use it correctly for a longer life span.
