Cleaning Procedure
The following instructions are a basic procedure for

• Be sure to follow your national and state sanitary
standard codes and local regulations.
• Use appropriate cleaning and disinfecting agents, at
intervals appropriate for product processed.
• Follow cleaning product manufacturer’s instructions.
1. Remove the pump from the fluid container. Operate
it to pump out as much fluid as possible.
2. Flush the system thoroughly with an appropriate
cleaning solution.
3. Set the director valve (BC) to UP to raise the ram.
4. If needed, use the air assist valve (BG) to help lift
the ram plate.
