CLEANING
RECOMMENDED WEEkLY CLEANING:
This should be done in conjunction with the recommended weekly cleaning of your CDS-2 or CDS-3 machine. The
CDS 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 CDS 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.
