Installation / Operation 6

ELECTRICAL CONNECTION

Hazardous voltage. Risk of dangerous or fatal electric shock. Plug the pump into a 115 Volt, 60 Cycle, Ground Fault Circuit Interrupter (GFCI) protect- ed grounded outlet only. The pump is equipped with a 3-wire grounded cord and plug. Do not modify or remove the plug. Make sure the outlet meets the National Electric Code or the Canadian Electrical Code, as applicable. To avoid dangerous electrical shock haz- ard, keep the cord dry at all times. See Figure 2.

AUTOMATIC PRESSURE CONTROLLER

The Automatic Pressure Controller mounts on the pump. It protects against:

•Run-dry operation;

•Overheating;

•Frequent starts caused by small water losses in the system;

•Pressure drop.

The Automatic Pressure Controller features the following LEDs and controls:

“POWER ON” LED: indicates that the unit is electrically connected and that voltage is present. The pump is ready to operate.

“PUMP ON” LED: indicates that the pump is running and actually pumping water.

“WATER FAILURE” LED: indicates that no water is detected coming into the pump.

“TEMPERATURE FAILURE” LED: indicates that the tem- perature inside the pump has reached 158° F (70° C).

“Starting Pressure” dial: allows you to set the system pressure at 15 to 45 psi (103 to 310 kPa). The pump will start automatically when the system pressure drops below the pressure point which you have set on the “Starting Pressure” dial.

“Reset” button: resets any safeties which have tripped and allows the pump to restart.

NOTE: The unit will not respond if the ‘RESET’ button is held down. It must be pressed and released to activate the reset function.

NORMAL OPERATION OF THE 3075SS

Burn Hazard. NEVER run the pump dry. Running the pump without water may cause pump to overheat and cause burns to persons handling the pump. It may also damage the impeller and may damage the seal, causing leaking or flooding, and will void the war- ranty. Fill the pump with water before starting it.

Make sure that the 3075SS has been properly installed, primed (see page 4), and that the suction pipe is unob- structed and open.

Turn the ‘STARTING PRESSURE’ dial to the minimum desired system pressure.

Plug in the pump. The ‘POWER ON’ and ‘PUMP ON’ lights will come on indicating, respectively, that voltage is present and that the pump is ready to operate.

The pump will start and will continue to operate until 15 seconds after the system pressure has risen past the set- point on the “STARTING PRESSURE” dial and flow has stopped.

WHEN DOES THE PUMP

STOP OPERATING?

Pressure Set-Point/No Flow: The pump will stop operat- ing and the ‘PUMP ON’ LED will go off 15 seconds after:

•The system pressure is above the point set by the STARTING PRESSURE dial, and

•The flow has stopped. This is normal operation.

Restart: A water flow in the system greater than

1 GPM or a drop in pressure below the STARTING PRESSURE set-point will cause the pump to restart and the ‘PUMP ON’ LED to light up. The pump will contin- ue to operate until 15 seconds after:

•It reaches the set pressure, and

•The flow stops.

NOTE: The 15-second delay in shutting off the pump prevents rapid cycling when water faucets are being turned on and off quickly (for example, when brushing teeth, etc.).
