Recovery Tips
x
Use the shortest hoses possible. Long hoses increase the recovery time.
Remove all restrictions in the hoses. Hoses with ball valves on the ends are
better than hoses that are self-sealing. Remove Schrader core valves when
possible from service ports.
x
Always identify the refrigerant you are recovering. This will minimize cross
contamination and help you plan for the amount of refrigerant you will be
recovering.
x
Always pump liquid out of the system first, and then recover the remaining
vapors. This will significantly speed up recovery rates.
x
With large amounts of refrigerant, use the liquid push-pull recovery method.
This method is three times faster than recovering liquid directly. Refer to the
liquid push-pull instructions on Page 16.
x
When possible, recover from both the high and low side service port on the
refrigeration system. This will speed up the recovery rate.
x
Use an agency approved in-line filter (P/N 07-1700) to prevent contaminants
from entering the STINGER.
x
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;
otherwise, the STINGER will not operate.
NOTE
: Although using a manifold gauge set will speed up the recovery
process, a manifold gauge set is not required.
