The "Preventive Maintenance" section of the Ecolab CS-40 manual is arguably the most important page for daily staff. Neglecting these steps leads to poor cleaning results and costly repairs.
According to standard operation procedures, your daily routine should include:
The Ecolab CS-40 is a tank of a machine, but even the best equipment needs guidance. Treating the operator's manual not as a drawer-stuffer, but as a training tool, is the difference between a smooth dinner service and a chaotic one.
Pro Tip: Laminate the "Daily Maintenance" page from the manual and tape it to the wall above the dishwasher. It serves as a great reminder for closing staff and helps new hires get up to speed quickly!

Q: Can I use the CSH 40 with non-Ecolab chemicals? A: Technically yes, but the manual voids the warranty if damage occurs. Non-Ecolab chemicals may have different viscosities or corrosive properties that damage the flow meter or pump diaphragm.

Disconnect the discharge tube and manually clean the barbed fitting with a paperclip or small drill bit (by hand only). The "Preventive Maintenance" section of the Ecolab CS-40
Q: How do I know if my flow meter is bad? A: With water flowing, disconnect the two wires from the flow meter. If the pump stops clicking instantly, the flow meter is fine. If it keeps clicking, the control board is faulty (replace PCB – part # CSH40-PCB).
Q: The manual says “Do not exceed 120°F water.” Why? A: Above 120°F, the polypropylene housing softens, and the pump diaphragm loses elasticity, leading to inaccurate draw rates and eventual failure.
The #1 service call for CSH 40 pumps is improper tube loading. If you aren't getting prime or the flow is erratic, re-read this part of the manual.
How to do it right:
Pro tip from the manual: Always replace the squeeze tube when you change chemical drums. A collapsed tube is the silent killer of peristaltic pumps.
