Directions for Use:

Do not remove QwikCheck from package until ready to use. The QwikCheck indicator paper is golden-yellow before testing.

  1. Insert the valve core depressor into the center of the suction-side, vapor-service/Schrader valve while the system is operating.


  2. Allow vapor to flow through the QwikCheck for 2 seconds. If the indicator paper does not change color, the acid level is okay.


  3. If the indicator paper changes color slightly, add QwikShot Acid Flush to remove the acid. If the paper turns red, the acid level is very high; change the oil and the filter-drier, and then add QwikShot Acid Flush.
