for each tip). The “Rinse” alarm LED will turn off when the Rinse Procedure has been satisfied for both sides.

“free flowing” connector for this purpose.

5. Place an empty container under dispense tip and pull the corresponding Dispense Handle until the clean soapy
water is dispensed from the dispense tip.

(9.46L) of 120°F (48.9°C) water to ensure 100 ppm of available chlorine.
8. Again, repeat steps 4 and 5 with the sanitizing solution. Once sanitizing solution is being dispensed, stop
pulling the handle and allow the solution to sit for 5 minutes.
9. Repeat step 6 to flush out the sanitizing solution from the pump tubing.
