Preventive Maintenance Recommendations
5.1
Generally, all technical equipment needs a minimum level of preventive maintenance. Regular maintenance is recommended to ensure
trouble-free operation and long life of the product. It is also recommended, as a good service practice, to record a maintenance log with
counter values, date, and time describing the maintenance and service actions.
Danfoss recommends the following inspections and service intervals for the product.
The service schedule for part replacements can vary depending on operating conditions. Under specific conditions, the
combination of stressful operation and environmental conditions work together to reduce the lifetime of the components
significantly. These conditions can include, for example, extreme temperature, dust, high humidity, hours of use, corrosive
environment, and loading.
For operation in stressful conditions, Danfoss offers the DrivePro® Preventive Maintenance service. DrivePro® services extend the lifetime
and increase the performance of the product with scheduled maintenance including customized part replacements. DrivePro® services
are tailored to your application and operating conditions.
