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 Operating Manual Troubleshooting guide 6 Failure to start .6 Oil leakage .6 Failure to pull a good vacuum 6 ® Allows the pump to be shut off while still connected to the A/C-R system, which is handy for checking rate of rise. With the valve handle in the OPen position, the pump is open to the system being evacuated. In the ClOse position, the pump is isolated from the system. This minimizes pump oil pulled into the pumping module, making start-up easier and reducing wear and tear on the pump components. High vacuum rating The two-stage, offset rotary vane design provides powerful, quiet, high vacuum capability and ensures moisture removal, while the high pumping capacity reduces evacuation time. Lifetime filtration The intake filter prevents foreign matter from entering the pumping chamber, and an internal exhaust filter separates oil vapor from the exhaust flow. Directed exhaust The exhaust is expelled through the handle to direct it away from the service technician. Gas ballast A precise amount of atmospheric air is introduced into the pump, preventing condensation of moisture vapor and helping maintain the purity of the pump oil. By using the gas ballast, the pump operates more efficiently and pump life is extended. Sure-grip handle 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. Compact design The pump measures approximately 40 cm long, while aluminum housing and offset rotary vanes keep the pump weight low, making it easy to carry.
