Ti ti TIME OF DAY ARROW.
4. Timer operation. TRIP PINS
a. Start with all trip pins towards the center of the timer dial.
b. Push out from the center all trip pins that are between the times the aerator or lighting is
to operate.
c. Turn the outer dial clockwise to align the time of day to the stationary arrow positioned at
“9 o'clock”. Close the panel and turn the main disconnect on. When the main disconnect is
off or in the case of power failure the timer/s will not operate and the time of day will need to
be reset.
d. Timer control of the unit and lighting is enabled when in AUTO.
B. Energizing the Unit (To be performed by a qualified technician)
1. Single Phase Units: Motor rotation is factory determined and not field adjustable.
2. Three Phase Units: Verify correct motor rotation (Counter Clockwise looking at the top/impeller end of the unit). Check
current readings on each phase. Verify three phase operating currents are balanced within 5%.
To calculate the percent of current unbalance:
Determine the Average Current:
a. Measure each of the three phase currents
b. Add the three phase amperage values together.
c. Divide the sum by three.
d. This is the average current value.
Determine Current Unbalance:
a. Select the phase current with the greatest difference from the average (calculated above).
b. Determine the difference between this phase current and the average current value.
c. Divide the difference by the average.
d. Multiply the result by 100 to determine percent of unbalance.
3. Use connection diagram 1, 2 or 3 at right which results in the
lowest current unbalance. Roll the motor cable leads on the AS 2 ‘3 us 2 eB ci 2

b. If the phase farthest from the average moves on each of the
connections with a particular motor lead, then the primary DIAGRAM 1 DIAGRAM 2 DIAGRAM 3
cause of unbalance is the "motor side" of the circuit.
Consider: damaged cable, leaking splice, poor connection, or a faulty motor as possible causes.
4. Once the unit is operational record the operating voltage, amperage, power control center serial number, power cable
length and cable gauge on the label inside the power control panel.
MAINTENANCE
For Warranty Consideration Work Must Be Performed By an Authorized Service Facility
A. Keep the pumping chamber components and screen free of debris. Damage can occur to a clogged aerator.
B. Once a year, disconnect the unit from the power source and physicaily inspect the aerator, fioat and electrical cable.
Visible damage to the motor unit or cable should be repaired to avoid safety hazards and/or potential failure.
C. Every three years, an oil change using “Otterbine Oil” is recommended to keep your aerator operating smoothly.
When a unit is properly cared for, it will give you years of trouble free service.

WINTERIZATION
Damage caused to the motor due to freezing will not be covered under warranty
In locations with extended periods of freezing temperatures the aerator may become frozen into the water possibly
causing damage. Otterbine recommends the following Concept 3 units be removed from the water during freezing
temperatures: ROCKET, PHOENIX, TRI-STAR, CONSTELLATION, COMET, GENESIS, EQUINOX, and OMEGA.
The GEMINI, SATURN, and SUNBURST pump higher volumes of water which helps to keep the water around the aerator
from freezing. 24 hour a day operation will further decrease the opportunity for the unit to freeze in, although during
periods of extremely cold temperatures this will not prevent the water from freezing.
