Frozen Beverage Dispensers

Cleaning and Sanitizing 37x, 56x, and 77x Dispensers

FBD dispensers are shipped from the factory cleaned and sanitized in accordance with NSF guidelines. After installation of
the dispenser, the operator must provide continuous maintenance as described in this bulletin and always adhere to state
and local codes to ensure proper operational and sanitation requirements are met. Failure to properly clean and sanitize the
dispenser can negatively affect components, drink quality, and dispenser operation. FBD recommends that the dispenser
be sanitized annually or when the dispenser has been non-operational for an extended period of time.
A few precautions when cleaning:
• Water lines should NOT be disconnected during the cleaning and sanitizing process. This is to avoid
contamination.
• FBD recommends using Stera-Sheen or Kay-5 for sanitizing.
• DO NOT use strong bleaches or detergents when cleaning the equipment. They could damage the plastic and
metal parts.
• DO NOT use metal scrapers, sharp objects, steel wool, scouring pads, abrasives, solvents, etc., on the dispenser
as they can damage the finish on various materials.

Daily Cleaning

Use a mild soap solution, such as hand dish-washing detergent, diluted with water at 90°F to 100°F (32°C to 38°C) to clean
the exterior of the equipment. Remove all product residue from the surfaces of the dispenser. Rinse thoroughly using clean
water also at 90°F to 100°F (32°C to 38°C) to remove the remaining soap. Remove the drip tray (if not connected to drain
plumbing) and cup rest and clean in a sink using a mild soap solution.

Sanitizing

The dispenser should be sanitized annually. Follow Kay-5 or Stera-Sheen directions for preparing the solution with clean
water at 90°F to 100°F (32°C to 38°C). Kay-5 or Stera-Sheen are preferred because they also contain ingredients to assist
in cleaning. The following procedure must be followed for sanitizing the dispenser in accordance with NSF guidelines. The
process describes the procedure for one barrel. Repeat for additional barrels.
For 37x and 77x, press the up or down arrow on the keypad to highlight the barrel to be sanitized. Press the green
button and then select OFF. Press the green button again and select DEFROST.
