Operating Instructions

Pre-Operation Checks

Verify all wiring connections are secure.
Ensure the enclosure door is properly closed and latched.
Confirm the motor and pump system are ready for operation.

Starting the Pump Panel

Engage Disconnect: Turn the flange handle disconnect to the "ON" position to apply power to the control circuit.
Select Mode: Use the Hand/Off/Auto selector switch on the cover to choose the desired operating mode:
- HAND: For manual operation. Press the "START" pushbutton to energize the motor. Press "STOP" (or "RESET" if an overload occurred) to de-energize.
- OFF: Disables all motor operation.
- AUTO: For automatic operation, typically controlled by an external float switch or pressure sensor. The motor will start and stop based on the external control signal.
Start Motor: If in HAND mode, press the "START" pushbutton. The motor should begin operation.

Stopping the Pump Panel

Manual Stop: If in HAND mode, press the "STOP" pushbutton.
Automatic Stop: In AUTO mode, the motor will stop when the external control signal dictates.
Emergency Stop/Power Disconnect: Turn the flange handle disconnect to the "OFF" position to completely remove power from the panel.

Maintenance

WARNING: Disconnect all power to the pump panel before performing any maintenance. Failure to do so can result in severe injury or death.

Regular Inspection: Periodically inspect the enclosure for signs of damage, corrosion, or water ingress. Ensure all seals are intact.
Terminal Connections: Annually, check all terminal connections for tightness. Loose connections can cause overheating and equipment failure.
Dust and Debris: Keep the interior of the panel clean and free of dust and debris. Use a dry, non-conductive brush or vacuum.
Overload Relay: Test the thermal overload relay periodically according to manufacturer's recommendations to ensure proper operation.
Fuse Replacement: If a fuse blows, replace it only with a fuse of the same type and rating.
