Kasco EJ Series Operation & Maintenance Manual page 11

3-PHASE STARTUP PROCEDURE
Required motor starting/overload protection is not provided with this motor equipment. The installer must
supply a controller (control panel) with approved motor control and overload protection that matches motor
input Full load amperes. (See table below.) Overload protection must be selected or adjusted in accordance
with motor controller instructions.
Controller/control panel must also include Ground fault/leakage current protection. Installer must include
Ground fault/leakage current protection such as a GFI, RCD, RCBB, RCBO according to local and national
codes.
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. 3-phase Kasco units will run in a
clockwise rotation when looking down at the propeller. Keep clear of the propeller while verifying rotation.
Air will be blowing out (up) of the pump chamber when rotating in the correct direction.
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 fountain nameplate
ratings.
3. Verify all switches, circuit breakers, and motor starters are in the OFF position
4. Connect electrical service to the control panel.
5. Connect the fountain power cord to the panel as shown in the electrical schematic.
6. Adjust motor overload protection according to motor full load amperage and motor controller
instructions.
7. Pump rotation: The pump rotation is clockwise when looking down at the propeller. Apply power to the
control panel. Turn on the motor starter.
8. Momentarily turn on the fountain. Do not run the fountain 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
fountain 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 fountain on page 9.
Record the following data while the unit is operating in the water under load:
