Recommendations of fluid and filter maintenance

©
Danfoss | July 2019
To ensure optimum life of D1 pumps, perform regular maintenance of the fluid and filter. Contaminated
fluid is the main cause of unit failure. Take care to maintain fluid cleanliness when servicing.
Check the reservoir daily for proper fluid level, the presence of water, and rancid fluid odor. Water in the
fluid may be noted by a cloudy or milky appearance or free water in the bottom of the reservoir. Rancid
odor indicates the fluid has been exposed to excessive heat. Change the fluid immediately if these
conditions occur. Correct the problem immediately.
Change the fluid and filter per the vehicle / machine manufacturer's recommendations or at these
intervals: Change the fluid more frequently if it becomes contaminated with foreign matter (dirt, water,
grease, etc.) or if the fluid is subjected to temperature levels greater that the recommended maximum.
