Daily: RINSING

1.Open the dispenser door.

2.Select Rinse on the Function Selector Switch and Run on the Mode Selector Switch.

3.Close the dispenser door.

4.Place a 1/2 gal (2 liter) container under the appropriate dispense nozzle or nozzles.

5.Activate the Dispenser of the appropriate side or sides for approximately twenty seconds or until the hot water is clear or has no concentrate coloring in it.

6.Open the dispenser door, select Normal on the Function Selector Switch, and then close door.

Note: To clear the “Rinse” alarm, activate each dispenser until the flow stops automatically (approx. 20 seconds for each tip). The “Rinse” alarm LED will turn off when the Rinse Procedure has been satisfied for both sides.

Daily: PARTS WASHING

1.Remove and wash the drip tray, drip tray cover, and cup tray in a mild detergent solution. Rinse thoroughly.

2.Wipe splash panel, area around dispense nozzles, door, and cabinet with a clean damp cloth.

Weekly: SANITIZING

1.Open the dispenser door.

2.Select Prime on the Function Selector Switch and Run on the Mode Selector Switch.

3.Remove the bag connector from the product box and disassemble or prop open the internal valve to allow free flow of product through the connector. NOTE: Cutting the mating fittings from an empty bag makes an excellent “free flowing” connector for this purpose.

4.Place the bag connector into a one-gallon (3.8 liter) container of warm soapy tap water 140°F (60°C).

5.Place an empty container under dispense tip and activate the corresponding Dispenser until the clean soapy water is dispensed from the dispense tip.

6.Repeat steps 4 and 5 with warm tap water 140°F (60°C) to rinse the soapy water from the pump tubing. Continue dispensing until the water is clear, and no soapy water is being dispensed.

7.Prepare 2.5 gallons (9.46L) of sanitizing solution by dissolving 1 packet of Kay 5 sanitizer into 2.5 gallons (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 visible, continue to dispense for 1 minute. Release handle and allow solution to sit for 5 minutes.

9.After soaking for 5 minutes, activate the dispense switch a second time, this time for 2 minutes. After 2 minutes, release the dispense switch.

10.Repeat step 6 to flush out the sanitizing solution from the pump tubing.

11.Remove the mating connector from the bag connector.

12.Reattach the bag connector to product box.

13.Select Normal on the Function Selector Switch and Run on the Mode Selector Switch.

15.Repeat steps 1 through 14 for other dispense head.

16.Wipe internal and external surfaces with a clean, damp cloth.
