WARNING: PHYSICALLY disconnect the unit and lights from their
electrical source before entering, wading or swimming in the water in
which they are installed. Only factory approved power cord is to be
used. Do not splice or repair the cord, replacement is necessary if
damage occurs.

Aerator Equipment
Unpack and inspect your aerator, report any damage to the carrier that delivered your aerator. Make sure you
havereceived the following: 1. Unit - you will find a label located on the housing of the unit.
Check the label to make sure you have received the correct
horsepower and voltage aerator.
2. Float - including hardware kit to mount float to the unit or
extra hardware kit if float already mounted to unit
3. Power Control Center - you will find a label inside of the
Power Control Center door. This label lists the voltage and
horsepower of the control center. Verify that the aerator and
control center are the same horsepower and voltage.
4. Power Cable Assembly - verify that you have received the
correct length.
5. Warranty Registration Card - make sure to fill in your Otterbine warranty registration card and send it
back to the factory so that we can send you our bi-annual customer newsletter, which will keep you up to date

Electrical/PCC Installation
This weather resistant NEMA 3R Power Control Center comes complete with a twenty-four hour on/off timer,
magnetic contactor with overload relay, surge arrestor, disconnect, overcurrent protection, HOA switch, and
ground fault protection (where applicable). All internal connections are pre-wired. All electrical specifications
are located on the door of the Otterbine Power Control Center. Otterbine recommends that all ELECTRICAL
WORK BE DONE BY A QUALIFIED, LICENSED ELECTRICIAN. Make sure that all electrical work
conforms with local, state and national electrical codes.
NOTE: Otterbine suggests coordinating electrical installation with physical installation. The electrician will
need to be on hand for a one minute dry-run test of the unit and will also need to check the running amperage
after installation. These electrical tests are a crucial part of the installation process and should not be
ignored. A. Install the Otterbine Power Control Center as close to the pond as possible.
CAUTION: The Power Control Center should not be accessible from the water.
ATTENTION: la loite de control ne doit pas être accessible de l'eau.
WARNING: Screw connections may loosen during shipping, verify that all screw
connections are tight before energizing PCC.
CAUTION: Otterbine recommends that the PCC not be mounted in direct sun
light when installed outdoors.
B. Your Otterbine Power Control Center can be mounted indoors or outdoors.
1. When mounting outdoors Otterbine suggests that you use a piece of exterior
plywood and sturdy 4 x 4 post(s).
2. When mounting indoors the PCC can be mounted directly to the wall.

Mooring theAerator
An illustration showing how to moor an aerator is given in Figure 4.
mooring
Figure 4
E. You will need the following items in order to moor your Otterbine aerator.
1. Use all brass and stainless steel hardware in the installation of your Otterbine aerator.
2. Otterbine recommends using 1/4"/.63 cm or 1/2"/1.25 cm polypropylene rope or stainless steel cable
for your mooring lines.
3. At the mooring points themselves you will need a wooden stake, 1/2"/1.25 cm of rebar or a "duck
bill" type earth anchor --see Figure 5.
F. Choose a suitable location for your Otterbine aerator. See the aerator location chart on page 9
to determine the best aerator location for the most efficient and effective aeration.
G. Secure your first mooring point. If you are using a stake or 1/2"/1.25cm rebar, make sure to pound the
mooring point securely into the ground on the outer edge of the pond. If you are mooring with an earth anchor,
you will need to place the earth anchor two feet into the pond and then pound the earth anchor about two feet
into the pond bottom. The earth anchor will allow your mooring lines to be virtually unnoticeable as it will be
hidden two feet beneath the surface of the water.
H. Attach the mooring lines to the holes in the float. Use a strong, tight knot as it will secure the
Otterbine aerator in its place.
I. Launch your aerator into the water. Walk one mooring line around to the other side of the
pond.
J. Pull your Otterbine aerator into your previously chosen location.
K. Put in the other anchor or stake. Tie down your Otterbine aerator leaving enough slack in your
lines to allow the aerator to turn 90o or 1/4 turn. The slack in the lines will allow for proper start up,
wave action, and fluctuations in the water level. Proceed to step L (page 16).
Figure5
• Duckbill Earth Anchors are driven into the ground, using a drive rod
and heavy hammer, compacting the earth as they drive downward,
until they reach the recommended depth. After removing drive rod,
installer pulls up on cable. This planes or rotates the anchor into
load lock position, like a toggle bolt in undisturbed earth.

Anchoring theAerator
An illustration showing how to anchor an aerator is given in Figure 6.
anchoring
Figure 6
E. You will need the following items to anchor your Otterbine aerator:
1. Use all stainless steel and brass hardware in the installation of your Otterbine aerator.
2. Otterbine recommends using 1/4"/.63 cm or 1/2"/1.25 cm polypropylene rope or stainless
steel cable for your anchoring lines.
3. Two 60 - 80 pound anchors/two 27 - 36 kilo anchors.
4. Small boat.
F. Choose a suitable location for your Otterbine aerator. See aerator location chart on page 9 so that you
can place your aerator in the best location for the most efficient and effective aeration.
G. Launch your aerator into the water upside down, with the motor housing sticking up into the air.
Take a piece of rope and pass it through one of the holes on the float.
H. In a small boat tow the aerator into your previously chosen location.
I. Determine where to locate the anchors. Where the anchors are located will vary depending on the depth of
your pond. See the chart below to determine the best location for your anchors.
J. Drop in the first anchor line. Place your aerator in the desired location and securely tie the anchor line to
one of the holes on the outside edge of the float.
K. Drop in the second anchor line. Securely tie the anchor line to the hole on the outside edge of the float
which is directly opposite of the first anchor line that was tied onto the float. Make sure the unit can rotate 90o
or 1/4 turn. The slack in the anchoring lines will allow for proper start up, wave action, and fluctuations in the
water level. Flip the unit over. Proceed to step L (page 16).

3. Check current readings in amps on each leg using the three possible hook-ups. Roll the motor
leads across the starter in the same direction to avoid motor reversal. EXAMPLE:
4. Calculate the percent of current unbalance:
A. Add the three line amp values together.
B. Divide the sum by three, yielding current average.
C. Pick the amp value that is furthest from the average current (either high or low).
D. Determine the difference between this amp value (line C) and the average (line B).
E. Divide this difference (line D) by the average (line B).
F. Multiply the result (line E) by 100 to determine percent of unbalance.
5. Current unbalance should not exceed 5% at the service factor load. If unbalance cannot be
corrected by rolling leads, locate source of unbalance & correct it. IF Leg furthest from average stays
on the same power lead, THEN the primary cause of unbalance is the power source. IF leg furthest
from average moves on each of the hookups with a particular motor lead, THEN the primary cause of
unbalance is the "motor side" of starter. Consider: damaged cable, leaking splice, poor connection, or
faulty motor as possible causes.
6. Record running voltage & running amperage, power control center serial #, and cable length
and size on the sticker inside the power control panel. Proceed to step N.
N. If GFCI or EPD is installed, have the electrician test the device for proper operation.
O. Lock your enclosure with a padlock to prevent any type of vandalism. Set the "hand-off-auto" switch
located on the outside of your Power Control Center to the HAND or AUTO position. The HAND position on
the switch will let your aerator run continuously. The AUTO position on the switch will allow the timer inside
your aerator to operate the unit. See page 5 for timer operating instructions. Your aerator should be running at
this point and installation is complete.
CAUTION: Theaeratorshouldbeallowedtoruncontinuouslyfor48hoursafterinstallation. Thiswillallowthe
