Do not use GFCI input

power. This will cause nuisance faults.

Disconnect and lockout

electrical power before installing or servicing any electrical equipment.

Electrocution hazard.

Controller Input Ground Terminal (GND) and all exposed metal piping, including pressure transducer case, must be connected to the service entrance ground terminal.

All electrical work must

be performed by a qualiﬁed technician. Always follow the National Electrical Code (NEC), or the Canadian Electrical Code, as well as all local, state and provincial codes.

VFD Controller Hazard Statements

Always treat this

controller as energized until power supply to the controller has been removed for 5 minutes.

Electrocution Hazard.

Opening SWITCH INPUT does not de-energize controller or any of it’s outputs.

Avoid property

damage caused by pressure relief valve opening. Pipe the pressure relief valve discharge to a drain or other location so that property damage and ﬂooding will not occur.

Locate the tank and

transducer where they will not freeze.

Do not install any

valves, ﬂow control devices or ﬁlters between the pressure transducer and the pump. It is allowable to run branches off the pipe between the pump and transducer as long as no ﬂow restricting devices are between the pump and transducer.

Any exposed metal

in the system piping, including transducer case, must be grounded to the service entrance per NFPA 70: National Electrical Code, Article 250.

Motor Overload Setting Dial

Failure to properly

adjust the Motor Overload Setting before applying power may damage the motor or wire and void the warranty.

Pressure Adjustment

The INCREASE and DECREASE pushbuttons are used to set the desired pressure. To adjust pressure, press and hold (do not tap) the button until the desired pressure is obtained. It may take a full minute to adjust the pressure from maximum to minimum, please be patient. Pressure can only be changed when the pump-motor is running.

Controller Status Indicator (Light Visible Through Window in Cover) The controller status indicator light has 3 possible modes:

• Solid green = Standby, pump not

running. There is no water ﬂow or the SWITCH INPUT is open.

• Blinking green = Pump running.

There is ﬂow (possibly a leak) and the SWITCH INPUT terminals are connected to each other (closed).

• Red = Error/Fault. Light will blink

to indicate a particular fault. See Troubleshooting Section for Fault Codes.

Splicing Drop Cable

The underwater connection where the drop cable connects to the motor wires must be done using a waterproof heat shrink kit.
