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.

DANGER

CAUTION

WARNING

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.
