Liquid Push-Pull Operations Continued
4.
Open both the vapor and liquid valves on the DOT recovery tank.
5.
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.
6.
If a sight-glass is being used, you should watch it to determine when all of the liquid
has been removed from the system.
7.
The liquid push-pull recovery method will not pull a vacuum in the system. You must
turn OFF the STINGER and reconfigure the hoses for vapor recovery operations as
described on Page 9.
