System Usage Guidelines

To ensure optimal performance:

• Use LM-9D as a single fluid; do not mix with other heat transfer media

• Ensure system is fully cleaned, purged, and dried before filling

• Avoid water contamination during operation

• Recommended use in closed-loop systems

• Nitrogen sealing is recommended to prevent moisture ingress

• Follow proper industrial installation standards

• Ensure the temperature difference between coolant freezing point and system minimum temperature is more than 10°C

• When actual viscosity exceeds 80 cP, consider selecting a lower viscosity model
