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... -

(Optional) STINGER off when the recovery cylinder reaches 80% of its liquid-fill limit. Note: If this option is installed, the STINGER will not operate unless it is connected to a recovery cylinder with a compatible level-float switch. If the recovery cylinder does not have a float switch, then a shorting cap must be installed on the shutoff cord. - Page 8 Description of Features Continued 1. Inlet Gauge 5. Outlet Gauge 2.

Page 9: Vapor/Liquid Recovery Operations
Turn the inlet and outlet valves to their “OPEN” position, and the PURGE valve to its “RECOVER” position. Open the vapor valve on the DOT recovery tank. Use the rear mounted power switch to turn ON the STINGER. The compressor will now begin to recover refrigerant. -
Page 10: Standard Recovery Hose Connections
Attention: You must use an agency approved in-line filter when recovering liquid. Contaminants (particularly from the bottom of recovery cylinders) can enter the STINGER and become lodged in the valve seats causing damage and resulting in leaks. We recommend using Bacharach in-line filter P/N 0007-1700 to guarantee optimum... -
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 Continued 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.

“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. -

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 0007-1700) 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;... -
