3-2 Description and Operation
• USA cleaning.
• Local cleaning extra water.
• Local cleaning hot water.
Cluster Cleaning
All parts that make contact with milk on all the robot units and the milk line in a cluster are rinsed and
cleaned during a cluster cleaning. All milking robots in the cluster do a pre-rinse, a main cleaning and a
post-rinse. The amount of hot water to clean the robot unit and the duration for the pre-rinse and post-
rinse is set on the E-Link. A cluster cleaning starts at the time set on CRS. If the water supply has a USA
configuration and the USA cleaning is set, the post-rinse is done with warm water with a sanitizer solution.
Pre-Rinse
During a pre-rinse water flows through the milk jar, teat cups and milk tubes to the milk jar, and the pre-
milk device. At the start of the pre-rinse the milk line is blown empty.
Main Cleaning
During a main cleaning a hot cleaning solution flows through the milk jar, teat cups and milk tubes to the
milk jar, and the pre-milk device.
Post-Rinse
During a post-rinse water flows through the top milk jar, teat cups, milk tubes to the milk jar. Alternately
water is blown from the teat cups through the pre-milk device. At the end of the post-rinse water is
drained from the teat cups, milk tube and pre-milk device. After draining the water in the milk jar, the
water is pumped into the milk line and the milk line is blown empty.
If the water supply has a USA configuration and the USA cleaning is set, the post-rinse is done with warm
water with a sanitizer solution.
Milk Line Rinse
During a milk line rinse all milking robots in the cluster do a local rinse. All parts that make contact with
milk on all the robots and the milk line in a cluster are flushed with water. If the water supply has a USA
configuration and the USA cleaning is set, the cluster rinse is done with warm water with a sanitizer
solution. A milk line rinse starts when a set interval time on the CRS has passed since the last milking.
M4Use Flush
The M4Use flush will take approximately 6 minutes to complete and the buckets are filled with lukewarm
water. During a M4Use flush the robot unit does:
1. A cold water pre-rinse.
2. A blow empty cycle and a nozzle blow.
3. A hot water cleaning with chemicals will rinse the lines and nozzle.
4. Finish with a cold water post-rinse and nozzle blow.
Local Main Cleaning
During a local main cleaning the robot unit does a pre-rinse, a cleaning and a post-rinse. The duration for
the pre-rinse and post-rinse is set on the E-Link. The pre-rinse cleaning and post-rinse are similar to the
cluster cleaning. All parts that make contact with milk from the teat cups to the 3-way valves on the robot
unit are rinsed and cleaned with:
• Cold water.
• Hot water and alkaline.
