Use weight scale A scale (P/N 2010-0000) must be used to indicate when the recovery tank is 80% full when the STINGER does not have the 80% Shutoff Kit option installed. Avoid dangerous environments Although the unit can be used outdoors, we do not recommend operation in the rain, or in wet locations. -

Eye: In case of liquid contact, immediately flush eye with water. Seek medical attention. Skin: Flush with water. Treat for frostbite by gently warming the affected area. CAUTION: All refrigerant hoses, recovery tanks, refrigerant lines, the STINGER unit, and other vessels containing refrigerants should be handled at all times as if under high... -

Proceed with the recovery process until the system pressure shows a vacuum. Turn OFF the STINGER for a minimum of 5 minutes; after which, determine the amount of refrigerant remaining in the system. Repeat this step until system pressure is below mandatory EPA levels. -
Page 10: Standard Recovery Hose Connections
Standard Recovery Hose Connections IMPORTANT NOTES FOR LIQUID RECOVERY The Stinger can be used for pumping virgin refrigerant on an intermittent basis. Unlike recovered refrigerant, virgin refrigerant does not contain oil. CAUTION: Routinely pumping virgin refrigerant through the STINGER can remove lubrication from the compressor, resulting in premature failure. -
Page 11: Liquid Push-Pull Recovery Operations
A scale or liquid-sight glass can be used to determine when all the liquid is recovered. The STINGER will not pull a vacuum using the liquid push-pull recovery operation. To finish the recovery operation, you must perform vapor recovery operations as described on Page 9. -
Page 12: Liquid Push-Pull Operations, Con't
Liquid Push-Pull Operations, Con’t. Open both the vapor and liquid valves on the DOT recovery tank. Turn ON the STINGER. The compressor will begin to “pull” vapors from the cylinder and “push” the liquid out of the system and into the recovery cylinder. -
Page 13: Liquid-Pull Recovery / Charging Method
STINGER. The virgin refrigerant is pulled directly into the system being charged. The STINGER keeps the pressure low in the system by removing vapor. For every pound of vapor removed, as much as 25 pounds of liquid refrigerant may be... -

“throttling” the inlet valve until the STINGER begins to run normally. WHEN RECOVERING LIQUID: If a loud knocking noise occurs, the inlet pressure on the STINGER should be throttled back by slowly closing the inlet valve until the knocking noise stops. This action will prevent compressor damage. -
Page 15: Purging The Stinger
Turn the purge valve (black knob center) slowly to the “PURGE” position (pointer DOWN position). The STINGER will now start purging itself of refrigerant. Allow the unit to run until the inlet gauge indicates that there is an adequate vacuum present in the system. -
Page 16: Dot Recovery Cylinder Safety
If your STINGER is not equipped with an 80% tank full shutoff cord, or if you are using a recovery cylinder that does not have a float switch, then you must use a scale to prevent overfilling the cylinder. -
Page 17: Recovery Tips
• Use an agency approved in-line filter (P/N 07-1700) to prevent contaminants from entering the STINGER. • If the STINGER has the optional 80% tank full shutoff cord installed, connect this cord to the recovery cylinder’s float switch. If the cylinder does not have a float switch, then be sure to install a shorting cap on the shutoff cord;... -
