120 Appendix B Milking System Cleaning Guidelines P/N 9040322
After warming up, the milking system must be brought into a closed circulation setup,
detergent added, and the hot water and detergent circulated for 10-12 minutes.
After being circulated in the milking system, the hot water and detergent must be
drained away.
Rinsing with cold water: the milking system must be rinsed with cold water in an
open circuit to remove all traces of detergent.
Cleaning Exterior Surfaces
CAUTION
Detergents are destructive. Do not use any kind of detergent on the
AfiFree155 body.
Moisten a soft cloth with water and gently rub the surfaces of the AfiFree155 bodies.
Performing an Acid Wash
Perform an acid wash three times a week, or more frequently when necessary. The
acid wash does not replace the daily cleaning routine.
NOTE
 There are some cleaning solutions available that remove both milk
residues and hard water salts.
 Follow all of the manufacturers’ recommendations, including:
concentrations, temperatures, and cleaning-cycle times. Excessive
use of chemicals may damage the AfiFree155i bodies.
To perform an acid wash (after performing a regular cleaning cycle with hot water
and detergent):
1. Rinse the detergent solution out of the system with cold water.
2. Circulate hot water and phosphoric and/or sulfuric acid for 10–12 minutes and
drain:
▪ Entry liquid: 70°C [158°F], minimum
▪ Returning liquid: 55°C [131°F], minimum
3. Rinse the system with cold water.
