OVERALL DIMENSION MOUNTING HOLE LAYOUT
C. 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.

UNIT ASSEMBLY
READ THE INSTRUCTIONS: Improper assembly may result in damage to the unit.
NOTES:
*Genesis Pump Chamber; The Float MUST be mounted before the Genesis Throat Assembly (Shown on page 20).
(The unit will be received with the pumping chamber already mounted)
*5HP "Open Throat" Units (Sunburst, Gemini, Saturn); If applicable, the Supplemental Float must be mounted to
the Main Float before installing on Unit (See Below).
A. Supplemental Float Assembly
*If the Supplemental Float is already mounted to the Main Float, continue with main float assembly below.
1. Place Main Float top face down.
2. Place the Supplemental Float on the Main Float as shown in the photo below.
3. Ty-Rap the floats together in four places (1 in each pocket).
4. Continue mounting Main Float.
B. Main Float Assembly
1. Stand the unit upright and place the float onto it so the holes in the float line up with the holes in the mounting brackets.
2. Place a fender washer onto a hex bolt and insert into one of the four holes in the float making sure it also goes through
the hole in the steel mounting bracket on the unit. Repeat this for the three remaining holes.
3. Place a flat washer and a nylon locknut onto each of the four hex bolts. Tighten each nylon locknut.
CAUTION: Do not over tighten lock nuts, damage may occur to the float and/or pump chamber.
Fasten supplemental Float w/ Ty-Raps

C. Mounting the Stabilizers (Comet Spray Pattern Only)
1. Mount each of the four stabilizer plates to the top side of a bracket using a hex bolt, a fender washer, and a nylon
locknut as shown below.
2. Mount each of the four stabilizer plate assemblies from Step C1 to the top side of an outer hole in the float using an
eyebolt, a fender washer, and a nylon locknut as shown. Do not over tighten. Damage may occur to the float.
D. Screen Installation
Debris Screens help to prevent clogging of the aerator and
are available for all Otterbine aerators.
1. Place the unit upside down on blocks so the pump chamber
does not get damaged.
2. Pull screen over motor unit until it reaches the lip on the
float.
3. Make sure the cable/s are running through the bushing in
the screen.
4. Fasten the screen to the lip on the float with the washers
and screws provided so they are evenly spaced around the
diameter.

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.
B. Pre-Startup Checks (To be performed by a qualified technician)
1. Factory connections may loosen during shipping. Verify tightness of all 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 & 230V Three Phase Units: The voltage between L1 on the input
terminal block to the neutral terminal must measure a nominal 120V.
3. Allowing the main door to be open and with the swing panel door closed follow GFCI instructions on page 11 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.
!TURN 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 lb. (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.

4. Timer operation.
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
“2 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
aerator output terminal block in the
same direction to avoid motor reversal. If the current unbalance
is not corrected by rolling leads, locate the source of the
unbalance and correct it.
a. When the phase farthest from the average stays on the
same power lead after being moved the primary cause of
unbalance is the power source.
b. When the phase farthest from the average moves on each of
the hookups 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. After 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
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: Use the oil level gauge. Do not overfill motor housing with oil.
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.
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 and 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.
