The motor is hermetically sealed and as such does not require lubrication or other care. The impeller rests in a clear see-through cover to allow occasional spot checks for dirt and grime when the media is being changed. The impeller well has an effective self cleaning feature, but regular maintenance will help to lengthen the life of the impeller and motor unit. Rinse dirt or slime from impeller well periodically.

The impeller should be cleaned during every filter change. Twist cover until it comes free, and withdraw impeller from cover. Dirt and slime should be rinsed from the impeller before replacing. Be sure that all parts on the impeller shaft are not lost during cleaning.

Occasional removal of the plastic well insert is recommended to ensure free water movement. To remove, press finger against insert to filter case and pull upward until insert is free.
