For 3-Phase Units: 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 qualified electrician.
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 propeller. Stand clear of the propeller while verifying rotation. If a Kasco 3 phase panel is supplied, follow the
instructions included with the panel in addition to the steps below.
Electrician:
1. Verify all screw terminal connections are tightened to specified 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 the control panel as shown in the electrical schematic that came with the panel.
5. Connect the aerator power cord to the panel as shown in the electrical schematic.
6. Set the motor starter overload to the FLA rating on the aerator nameplate.
7. Pump rotation: The pump rotation is clockwise when looking down at the propeller. 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 verified, with the power disconnected and locked out again, continue with installation of the aerator on

Record the following data while the unit is operating in the water under load: Voltage: L1-L2 ____________ L1-L3 ____________
L2-L3 ____________ Amperage: L1_______________ L2_______________ L3_______________
Current unbalance should not exceed 5% at full load
