OVERALL DIMENSION MOUNTING HOLE LAYOUT
Cc. PCC Mounting
1. To prevent damage to the enclosure mount the enclosure using all four (4) mounting holes.
2. Whenever possible do not mount the PCC in direct sun light.
D. PCC Cables & Connections
1. Only Otterbine Barebo, Inc. factory approved power cord is to be used from the PCC to the aeration unit with no
junction boxes or splices. Only use power cord gauges and lengths specified by Otterbine at the time of cable purchase.
(Contact your Otterbine Distributor for proper cable sizing)
2. It is recommended that all exposed cable between the PCC and the shoreline be installed in non-metallic conduit. It is
important that aerator and lighting cables be installed in individual conduits to avoid induced interference between cables
which causes random GFCI tripping.
3. Always use strain relief cord connectors to attach the Otterbine cable to the PCC.
4. Cables and conduits must only enter into the bottom of the PCC.
5. Factory connections may loosen during shipping. Verify tightness of all screw terminal connections before energizing.
6. Power input and output wiring connections are accessed from the bottom of the enclosure. The terminal blocks for the
cable connections are located behind the hinged swing panel. Loosen the captive screw on the right center of the swing
panel for access.

PHYSICAL INSTALLATION
WARNING: DISCONNECT POWER BEFORE INSTALLING, REMOVING, OR SERVICING UNIT
Concept 3 Otterbine aerators require a minimum 30"/75cm (40"°/100cm w! lights) of water depth.
A. Attach your Otterbine power
cable to the aerator.
1. Align the keyway on the cable pigtail
connector to the key on the aerator
bulkhead connector and plug together.
Thread the nut onto the bulkhead,
hand tighten only, do not use tools on
the pigtail connector nut.
Over tightening may cause the
connector to fracture and possibly
cause an electrical short circuit.
2. 5HP, 230V, 1 Phase units have a 3
pin bulkhead connector and a 3 pin
pigtail connector on the power cable.
All other ratings use 4 pin connectors.
3. A small amount of silicon compound has been factory applied to the female end of the aerator connector. The
compound is necessary to make a waterproof seal between the two connectors. DO NOT REMOVE COMPOUND! When
servicing the aerator re-apply compound. (Otterbine P/N: 48-0001).
4. Install the cable strain relief device. Pass the wire hoop from the strain relief through one of the holes in the float or
around the float bracket. Reattach wire hoop to strain relief (see above).
5. For additional protection fasten the power cable, after the strain relief, to a float hole using the cable ties provided.
“PIGTAN, CONNECTOR
BULKHEAD CONNECTOR
B. Pre-Startup Checks (To be performed by a qualified technician)
1. Factory connections may loosen during shipping. Verify tightness of ali screw terminal connections before energizing.
2. Apply power to the PCC. Verify the incoming voltage is correct at the input terminals and matches the nameplate rating
of the aerator. For 115V & 230V Single Phase & Three Phase Units: The voltage between L1 on the input terminal
block and the neutral terminal must measure a nominal 120V.
3. Allowing the main door to be open and the swing panel door closed follow GFCI instructions on page 10 to reset
aerator GFCI. Turn on disconnect and proceed.
4. With the aerator unit on the shore check for correct motor rotation. Briefly “bump” the M-O-A switch (Shown on Page 10) to
“MAN?” while observing the motor shaft rotation (turn on only long enough to establish operation and proper direction of
rotation). Aerator Shaft rotation MUST BE CCW looking at the top/impeller end of the unit.
ITURN OFF DISCONNECT BEFORE PROCEEDING!
C. Fasten Mooring Lines and Launch
1. Mooring using stakes: Shore mounted stakes provides the easiest access to the aerator. Use stainless steel and/or
brass hardware. Otterbine recommends using 1/4"(0.63cm) or 1/2"(1.25cm) polypropylene rope or stainless steel cable
for mooring lines. At the mooring points use a wooden or metal stake or duck bill type earth anchors. Earth anchors allow
the mooring lines to be hidden beneath the water surface. Drive the mooring stakes securely into the ground at the edge
of the pond or place earth anchors close to the shore in the water. Fasten the mooring lines to opposite outer holes in the
aerator float. Launch the aerator into the water, pull into the chosen location and fasten the lines to the stakes allowing
slack for the aerator to twist up to 1/4 turn. The slack in the lines allows for movement during start up, fluctuations in the
water level and wave action. Proceed to System Startup.
2. Mooring using Anchors: Use stainless steel and/or brass hardware. Otterbine recommends using 1/4"(0.63cm) or
1/2"(1.25cm) polypropylene rope or stainless steel cable for anchoring lines, use two 60 - 80 Ib. (27 - 36 kilo) weights for
anchors and a boat may be needed. Fasten the mooring lines to opposite outer holes in the float. Launch the aerator
floating upside down (motor housing facing up). With the lines attached drop the anchors into the water at the
predetermined locations. Adjust the lines to allow slack for the aerator up to 1/4 turn twist. The slack in the lines allows for
movement during start up, fluctuations in the water level and wave action.

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

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.
For Service, Repairs or Parts, Contact Your Local Otterbine Distributor
or
Call Otterbine Directly at 1-800-237-8837.
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.
