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. With the valve handle in the OPEN position, the pump is open to the system being evacuated. In the CLOSED position, the pump is isolated from the system. The two-stage, offset rotary vane design provides powerful, quiet high vacuum capability and assures moisture removal, while the high pumping capacity reduces evacuation time. The 15434 can be used for R-12, R-22, R-500, and R-502, as well as for R-134a. The inlet “tee ” has both 1/4 ” SAE male flare and 1/2 ” Acme fittings to accommodate hoses from either type of manifold. The exhaust is expelled through the handle to direct it away from the service technician. 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. 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. Your pump measures approximately 15 ” long, while aluminum housing and offset rotary vanes keep the pump weight low, making it easy to carry.

Improper use or connections may cause electrical shock hazards. Read and follow the instructions carefully and take precautions to avoid electrical shock hazards. Be sure that all associated devices are properly grounded before energizing circuits. The 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. Use separate manifolds and hoses for R-134a systems. Cross-contamination with other refrigerant types will cause severe damage to the A/C system and to service tools and equipment. Do not mix refrigerant types through a system or in the same container! Avoid breathing refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose, and throat. To remove R-134a from the A/C system, use service equipment certified to meet the requirements of SAE J2210 (R-134a recycling equipment). If accidental system discharge occurs, ventilate work area before resuming service.
