6.5. Chemical Cleaning and Sanitization Precautions
• Avoid direct skin contact with cleaning chemicals. Use appropriate
Personal Protective Equipment (PPE), such as safety glasses,
gloves and protective clothing.
• Flush all hoses and tank with clean water BEFORE adding chemicals.
• Pressure-test CIP system and connecting hoses with water before adding chemicals

before disassembly.
• Do not run a cleaning solution through the system when DC power is applied to the
module. Make sure the DC power is off before cleaning.
• Follow the manufacturer’s chemical safety instructions on the
container labels.
• Check the pH level in any solution before letting it flow to the drain. Follow all discharge
limitations.
