Sanitizing Procedure
1. Fill the bucket with 4 gal. (15.14 L) of warm water 120ºF – 180ºF (48ºC – 82ºC).
2. Measure 4 oz. (1/4 cup) (118cc) of the liquid detergent and add to the water.
3. Measure 2 oz. (1/8 cup) (60cc) of bleach and add to the water, then stir, mixing evenly.
NOTE: 1/2 oz. (15cc) of bleach per gallon (3.8 L) of water yields a solution of approximately 200 ppm Sodium
Hypochlorite needed to satisfy NSF sanitizing requirements.
4. Disconnect the concentrate line from the BIB and install the adapter on the quick disconnect so the line is open
to the sanitizing solution. Place concentrate inlet line into the bucket so that the Q.C.D. will stay at the bottom.
5. Position the SHURflo sanitizing valve in the “SANITIZE” mode. Open the dispenser valve allowing ALL the
solution to be pulled through the Q.C.D. fitting into the BRIX pump and out the water outlet line through to the
dispenser.
6. When the bucket is empty (approx. 15 min.), return the valve to the “DISPENSE” mode.
7. Product Purge: Reconnect Q.C.D. of the inlet line to the concentrate supply. Open the dispenser allowing the
pump to operate until all sanitizing solution is purged from the system, assuring that no off-taste will be detected.
