Robinair High Performance Vacuum Pumps Congratulations on purchasing one of Robinair’s top quality vacuum pumps. Your pump has been engineered specifically for air conditioning and refrigeration service, and is built with Robinair’s proven offset rotary vane for fast, thorough evacuation. You’ll appreciate these key features... Iso-ValveTM Allows the pump to be shut off while still connected to the A/C-R system, which is handy for checking rate of rise.

Before using your vacuum pump... Note on Motor Voltage Connections: In all cases, motors are designed for operating voltages, plus or minus 10% of the normal rating (see SPECIFICATIONS). Single voltage motors are supplied fully connected and ready to operate. 1. Verify that the voltage and frequency at the outlet match the specifications on the pump motor decal. Place the ON / OFF switch in the OFF position before you plug the pump into an outlet. Verify the gas ballast valve is closed.
To use the gas ballast feature... Moisture from the A/C-R system that is carried into the pump as a vapor tends to condense into a liquid and combine with the vacuum pump oil. When moisture contaminates the pump oil, it reduces the pump’s ability to reach its ultimate deep vacuum level. The gas ballast valve purges a small amount of atmospheric air through the exhaust chamber.
To maintain the high vacuum pump... Vacuum Pump Oil For maximum performance, Robinair recommends changing vacuum pump oil after each use. The condition and type of oil used in any high vacuum pump are extremely important in determining the ultimate attainable vacuum. Robinair recommends the use of our Premium High Vacuum Pump Oil. This oil has been specifically blended to maintain maximum viscosity at normal running temperatures and to improve cold weather starts.
b) Another method of dealing with heavily contaminated oil is to force the oil from the pump reservoir. To do this, allow the pump to run until it is warmed up. While the pump is still running, remove the oil drain cap. Slightly restrict the exhaust. This will back-pressure the oil reservoir and force the oil from it, carrying more contaminants. When the oil ceases to flow, turn off the pump. Repeat this procedure as required until the contamination is removed.
3. Verify the pump oil is clean. A badly contaminated pump may require several oil flushes. See OIL CHANGE PROCEDURE. Note: Use only high vacuum pump oil such as Robinair’s Premium High Vacuum Pump Oil. Other oils will prevent pull-down to a deep vacuum. 4. Verify the gas ballast knob is tightly closed. 5. Verify the oil is at the correct level. For maximum pump operation, the oil must be even with the OIL LEVEL line on the sight glass when the pump is running. See OIL CHANGE PROCEDURE.
