Confirm that all associated devices are grounded correctly before energizing circuits. Normal operating temperature will cause certain external portions of the pump to be hot to the touch. Do not touch the pump housing or motor during operation. For use on A/C-R systems using CFCs, HCFCs, and HFCs in conjunction with mineral oil, ester oil, alkylbenzene oil, and PAG oil as lubricants. Not for use with ammonia or lithium bromide systems. Not for use with flammable refrigerants. VacuMaster® High Performance Vacuum Pumps Congratulations on purchasing one of Robinair’s top quality VacuMaster® vacuum pumps. Your pump has been engineered specifically for air conditioning and refrigeration service, and is built for fast, thorough evacuation. You’ll appreciate these key features. High Vacuum Rating Lifetime Filtration Sure-Grip Handle Compact Design The two-stage rotary vane design provides powerful, quiet, high vacuum capability and ensures moisture removal, while the high pumping capacity reduces evacuation time. The intake screen prevents foreign matter from entering the pumping chamber, and an internal exhaust filter separates oil vapor from the exhaust flow. The one-piece, molded handle makes it easy to carry the pump to and from job sites, and the handle stays cool to the touch during operation. Aluminum housing and rotary vanes keep the pump weight low, making it easy to carry.

Note about Motor Voltage Connections: In all cases, motors are designed for operating voltages plus or minus 10% of the normal rating (see Pump Specifications). Single voltage motors are supplied fully connected and ready to operate. 1. Confirm that the voltage and frequency at the outlet match the specifications on the pump motor decal. 2. Confirm the ON-OFF switch is in the OFF position before you plug the pump into an outlet. 3. Remove and discard the exhaust plug from the exhaust fitting. 4. The pump is shipped without oil in the reservoir. Before starting the pump, fill it with oil. Remove the OIL FILL cap (red plastic plug at the front of the handle), and add oil until oil appears in the bottom of the sight glass. For oil capacities, refer to Pump Specifications in this manual. 5. Replace the OIL FILL cap, and remove the cap from one of the inlet ports. 6. Turn the motor switch to ON. 7. When the pump runs smoothly, replace the cap on the inlet port. This may take from two to 30 seconds, depending on the ambient temperature.
