3 Phase Startup Procedure
A Control Panel is not provided with your unit, 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.
Proper ground fault protection (RCD) must be provided at time of installation in your control panel
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/impeller. On J series units the upper pump
housing must be removed to see the propeller/impeller. Stand clear of the propeller/impeller while verifying rotation. Follow 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 your 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 your control panel as shown in the electrical schematic that came with the panel.
5. Connect the unit power cord to the panel as shown in the electrical schematic with your panel
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 propeller/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 verified, 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:
