3 Phase Startup Procedure
If a Kasco Control Panel is not provided, please refer
to the following warnings:
When inherent overheating protection is not provided:
use with approved motor control that matches motor
input in full load amperes with overload element(s)
selected or adjusted in accordance with control
instructions.
Utiliser un démarreur approuvé convenant au courant
à pleine charge du moteur et dont les éléments
thermiques sont réglés ou choisis conformément aux
instructions qui l’accompagnent.
When inherent overheating protection is provided:
use with approved motor control that matches motor
input in full load amperes. See table below.
Utiliser un démarreur approuvé convenant au courant
à pleine charge du moteur.
Note: The motor input in full load amperes is the
marked value or the service factor amperes, shown on
the namplate.

Control panels must be installed by a qualied electri-
cian.
If unit is connected to a circuit protected by a fuse, use
a time-delay fuse with this pump.
You must verify motor rotation before installing
the unit in the water.
3phase Kasco units will run in a clockwise rotation
when looking down at the impeller. On J series units
the upper pump housing must be removed to see the
impeller. Stand clear of the impeller while verifying
rotation. If a Kasco 3 phase panel is supplied, follow
the intructions with the panel . Also follow the steps
below.
Electrician:
1. Verify all screw terminal connections are tightened to
specied torque setting prior to energizing the panel.
2. Verify the electrical service (voltage and Phase)
matches the control panel and
aerator nameplates
ratings. Refer to the control panel instructions and
schematics for installation details.
3. Verify all switches, circuit breakers, and motor starters
are in the OFF position
4. Connect electrical service to this control panel as
shown in the electrical schematic that came with the
panel.
5. Connect the unit power cord to this panel as shown in
the electrical schematic.
6. Set the motor starter overload to the FLA rating on the
aerator nameplate.
7. Pump rotation: Remove the upper pump housing (if
you have a J series
aerator) by removing the three
screws attaching it to the lower pump housing. The
pump rotation is clockwise when looking down at the
impeller. Apply power to the control panel. Turn on the
15amp control circuit breaker, and motor starter.
8. Momentarily turn the Hand-Off-Auto switch to Hand.
This will run the
aerator. Do not run the aerator for
more than a few seconds on shore. If the rotation is
not correct. Disconnect and lock out power from the
control panel. Swap any two of the
aerator power cord
wires in the panel. This will cause the motor to reverse
direction. Reapply power to the panel and verify the
rotation is clockwise.
9. Once rotation is veried, with the power disconnected
and locked out again, reinstall the upper pump housing.
Run the
aerator one more time momentarily on
shore to ensure the housing was reinstalled correctly.
Disconnect and lock out power again and continue with
installation of the
aerator as detailed in the aerator
owner’s manual.
Record the following data while the unit is operating
in the water under load:
Voltage: Amperage:
L1-L2 ____________ L1_______________
L1-L3 ____________ L2_______________
L2-L3 ____________ L3_______________
Current unbalance should not exceed 5% at full load
