IMPORTANT NOTES FOR LIQUID RECOVERY
Do not pump virgin refrigerant with the STINGER. Unlike recovered
refrigerant, virgin refrigerant does not contain oil. Pumping virgin
refrigerant through the STINGER will remove all lubrication from the
compressor bearings, resulting in premature bearing failure. Use the
liquid push-pull method or the liquid-pull method to transfer large
amounts of liquid refrigerant (virgin or dirty).
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
pumping speed.
