QwikShot
®
Instructions for Use
For use with all refrigerants and oils used in air conditioning, heat pump, and refrigeration systems.
Step 1 - Check the System and the Refrigerant for Acid
f If the compressor has burned out, change the compressor, refrigerant and oil. While the system is disassembled, ush
acid from any components, (except the expansion device, lter-driers and compressor) with Qwik System Flush®.
When reassembling the system, change the lter-driers (adding a suction-line lter is recommended to protect the new
compressor).
f If the compressor has not burned out, and the system is operational, verify the system is properly charged and operating
properly, verify superheat or subcooling as applicable, then use QwikCheck® to determine if the refrigerant is acidic.
 If the refrigerant tests highly acidic (QwikCheck® indicator turns all red), change the refrigerant and oil. Also, change
the lter-driers since a high acid level indicates the current lter-driers are no longer functioning.
 If the refrigerant tests mildly acidic (some red on the QwikCheck®), then measure the temperature across the liquid-
line lter-drier (with the system on) to determine if a new drier is required. A temperature dierence of more than 2°F
indicates the lter-drier should be replaced. If there is no lter-drier in the system, you must add a lter-drier.
 If the refrigerant does not test acidic (QwikCheck® indicator stays yellow), go to step 2.
Step 2 - Determine the Amount of QwikShot® to use
f Use a half-ounce bottle of QwikShot® to treat up to a 6 ton system. QwikShot® will remove moisture and acid while
also reducing sludge formation and wear caused by oil degradation.
Step 3 - Add QwikShot® using a QwikInjector®
f Add QwikShot® into a charged and operating system by connecting the QwikInjector® (QT2510) between the high
and low-side service ports, connecting to the low side port rst. Follow the QwikInjector® instructions. Do not add
QwikShot® to a system before the system is evacuated (since the evacuation process will remove all the QwikShot®).
Optional Step 4 - After at Least 16 Hours of Operation, Check the System
f For highly acidic systems, after at least 16 hours of operation, you can recheck the system with a QwikCheck®. If any sign
of acid remains, repeat Steps 1-3.
