9.Make sure all hoses are connected. Place the main ON/OFF switch in the “ON” position.

10.Place one of the ON/OFF refill switches in the “ON” position, after a four second delay product will begin to flow through the hoses into the hopper. Be sure the switch selected is filling the correct hopper, if not, check the labels. See NOTE in step #4.

11.To test refill circuit short out probes on one of the hoppers with a screwdriver, so that hopper should shut off. Remove the screwdriver and the hopper will start to fill again after a four second delay. If hopper does not start to fill, check labels, refer to NOTE in step #4.

CLEANING

RECOMMENDED WEEKLY CLEANING:

This should be done in conjunction with the recommended weekly cleaning of your machine. The Hoppers must be empty before starting.

1.Prepare a 1 gallon cleaning solution consisting of 1 gallon of hot water and a sanitizing cleaner which contains 3-5% chlorine based sanitizer. Mix per manufacturers instructions

2.Remove connectors from each concentrate container and place them directly into the cleaning solution.

3.Energize each refill station and allow the cleaning solution to pump through the system into the hoppers. The cleaning procedure should remove the color stains from the tubing. If not, prepare another gallon of cleaning solution and repeat.

4.After the cleaning solution has been pumped into the hoppers, rinse the cleaning solution container with hot water.

5.Fill the cleaning solution container with hot water. Energize each refill station and rinse thoroughly. The amount of clean hot rinse water should equal the amount of cleaning solution pumped through the system.

6.Empty the hoppers of your machine and follow the recommended cleaning instructions.

NOTE: The hoses should be checked monthly for deterioration, cracks and possible discoloration from some concentrates. Replace the tubing when necessary.

MIX RATIO ADJUSTMENTS

1.Remove the top access panel.

2.Connect the test hose to the “WATER OUTPUT” to be adjusted.

3.Connect the provided hose (or other suitable water hose) to the “WATER INPUT”.

4.Ensure water regulator is set at 20 psi(137.9 kPa). Press the “TEST OUTPUT” switch and while water is flowing from the test hose, check that the gauge reads 20.

5.Place a one-cup container under the test hose. Press the “TEST OUTPUT” switch, and carefully measure and note the elapsed time from when water first flows form the test hose to when one cup of water has been dispensed. Hoses and tubing should be primed and free of substantial air spaces and/or bubbles prior to calibration.
