Most Common New Installation Errors to Avoid:
Panels equipped with the redundant off option:
- Redundant off float not connected
- Pump will not run in automatic mode on a standard panel. It will however, run in hand mode
- If the float is not available, secure jumper wire in place of the redundant off float
Panels equipped with thermal cutout connection:
- Pump does not run in Hand or Automatic mode
- Verify thermal cutout is connected
To test panel operation:
- Disconnect voltage; Tag and remove the thermal cutout wires
- Use a jumper wire (on panel terminal block) in place of the thermal cutout wires
- Reconnect voltage. If pump runs in hand mode, thermal cutout connection is incorrect or possible defective thermal switch in pump
Installation Tips to Assist in New Installation:
Incoming power:
- Correct incoming voltage: Example—208V or 240V or 480V
- Control Alarm voltage: L2——N
- Alarm-Control-Neutral
- For code some places require two 120V lines to come in and share neutral, otherwise bring in the hot lead to a L1 and neutral to N and jumper L1 and L1 together.
Floats: Have to be in correct order and on correct terminal block position

Make sure:
- Breakers ON; Overload ON; Motor protective switch ON
Three Phase panels:
- Make sure the transformer is hooked up to the correct incoming voltage
Seal Fail Thermal Cutout:
- Hooked up to correct terminal block connections
- Seal fail=infinite ohms open
- Thermal cutout=0 ohms closed
