Maintenance
Your Otterbine aerator requires periodic maintenance:
A. Once a year, disconnect the unit from the power source and physically inspect the aerator and
underwater cable for any cuts, cracks or breaks. These may cause oil leaks and/or electrical shorts. Inspect and
clean the pumping chamber components and screen.
B. After every three running seasons, a simple oil change is necessary to keep your unit running
smoothly. Otterbine oil must be used for this oil change. Please contact your local Otterbine distributor to
order a maintenance kit, p/n 12-0077.
WARNING: Do not overfill motor housing with oil, may cause damage.
When a unit is properly cared for, it will give you years of trouble free service. If a problem does arise, please
contact your Otterbine distributor or the factory directly at 1-800-AER8TER.
