Setup
Follow these steps to prepare your vacuum pump for first use:
- Unpacking: Carefully remove the pump from its packaging. Inspect for any shipping damage.
- Oil Fill: The pump is shipped without oil. Remove the oil fill cap and slowly pour Yellow Jacket vacuum pump oil into the reservoir until the oil level is between the "MIN" and "MAX" lines on the sight glass. Do not overfill.
- Power Connection: Ensure the power switch is in the "OFF" position. Connect the power cord to a grounded 115V AC electrical outlet.
- Initial Run: With the oil filled, turn the pump on for a few seconds to circulate the oil, then turn it off. Check the oil level again and add more if necessary.

Operating Instructions
This section details the steps for operating your vacuum pump for HVAC/R system evacuation.
- Connect Hoses: Connect appropriate vacuum hoses from the system to be evacuated to the inlet ports on the vacuum pump. Ensure all connections are tight to prevent leaks.
- Open System Valves: Open all valves on the manifold gauge set and the system being evacuated to allow for full vacuum pull.
- Start Pump: Turn the power switch to the "ON" position. The pump will begin to pull a vacuum.
- Monitor Vacuum: Monitor the vacuum level using a micron gauge connected to the system. Continue running the pump until the desired vacuum level (e.g., 500 microns or lower) is achieved and holds steady.
- Isolate Pump: Once the desired vacuum is reached, close the valves on the manifold gauge set to isolate the system from the pump.
- Turn Off Pump: Turn the power switch to the "OFF" position.
- Disconnect Hoses: Carefully disconnect the vacuum hoses from the pump and the system.
Maintenance
Regular maintenance is crucial for the longevity and performance of your vacuum pump.
Oil Change
Change the vacuum pump oil frequently, especially after evacuating systems with high moisture content or contaminated refrigerants. Dirty oil reduces pump efficiency and can cause damage.
- Drain Old Oil: Place a suitable container under the oil drain plug. Remove the drain plug and allow all old oil to drain completely. Dispose of used oil responsibly according to local regulations.
- Replace Drain Plug: Reinstall and tighten the oil drain plug.
- Refill with New Oil: Remove the oil fill cap and slowly pour new Yellow Jacket vacuum pump oil until the level is between the "MIN" and "MAX" lines on the sight glass.
- Run and Check: Run the pump for a few seconds, then turn off and recheck the oil level. Add more oil if needed.
General Cleaning
- Keep the exterior of the pump clean and free of dust and debris.
- Periodically check all connections and fittings for tightness.
Troubleshooting
This section provides solutions to common issues you may encounter with your vacuum pump.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump not starting | No power; faulty switch; motor issue | Check power cord and outlet. Ensure switch is ON. If problem persists, contact Yellow Jacket support. |
| Pump not pulling deep vacuum | Low or contaminated oil; system leak; clogged inlet filter | Change oil. Check all system connections for leaks. Clean or replace inlet filter. |
| Excessive noise or vibration | Low oil level; worn components | Check and add oil. If noise continues, professional service may be required. |
| Oil misting from exhaust | Overfilled oil; contaminated oil; normal operation with high moisture | Check oil level and drain if overfilled. Change oil if contaminated. This can be normal during initial pull-down of wet systems. |
