Recovery Tips
•
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.
•
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.
•
Always pump liquid out of the system first, and then recover the remaining vapors. This
will significantly speed up recovery rates.
•
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 11.
•
When possible, recover from both the high and low side service port on the refrigeration
system. This will speed up the recovery rate.
•
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; 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.
