The Most Trusted Soft Start For Well Pump Brands Available Today.

SoftStart Well Pump™ keeps your water pumps running efficiently - even on small generator power. Whether you’re using 120V or 240V power, it reduces the current needed to start pumps, and help keep water flowing during normal operation AND during power emergencies. By minimizing the inrush power spike, and mechanical stress at
startup, it extends pump life by reducing wear and tear on motor windings.

• Reduces startup current by up to 40%
• Starts a well pump on as little as a 3kW generator
• Quiets well pump start-up and operation.

The SoftStart Well Pump™ soft starter is installed between the power source and the water system’s pressure switch. See detailed instructions on the following pages. Installation should take less than one hour. If you do not see your wiring diagram on our online support pages, send us a picture of your pump diagram using our ticket support system, and we will customize it for you absolutely free.

There are no user serviceable parts inside the SoftStart Well Pump™ unit. The unit is sealed in resin to ensure a long life and to protect components from vibration, heat and cold.

WARRANTY:

The SoftStart Well Pump product is warranted to be free from defects in workmanship and materials for one (1) year after the date of purchase. This warranty is limited to the replacement of the product. See last page for details.

FOR 120/240 VOLT WELL PUMPS WITH 2-, 3- OR 4-WIRE CONNECTION.

SoftStart Well Pump™ twistlock wire connectors accommodate 12 and 14 gauge solid wiring.

1. Turn off all power to the pump and confirm it’s off. Never work on live circuits.

2. Confirm well pump is 120V or 240V. If circuit breaker is a double-wide 2-pole breaker (refer to A), then it is a 240V well pump.

3. Locate the wire from the circuit breaker panel going to the pressure switch feeding the well pump.

4. Find a good location on the wall to install SSWP with appropriate screws.

5. Cut the Romex wire near the center of the SSWP box.

6. Strip back approximately 1” of the outer cable sheath.

7. Strip back approximately 3/16” of the coverings on the black and red wires.

NOTE: Electrical code allows black and white wires to be used for 2-pole 240-volt service as along as the white wire is marked with black tape at the circuit breaker.

8. If using 14-gauge solid Romex wire, don’t remove the spring clamps in twist-lock connectors (refer to B).

9. If using thicker 12-gauge solid Romex wire, back the terminal screws out to remove the spring clamps. Then tighten terminal screws onto wires.

10. Assemble the Blue connector to the wire from the Circuit Breaker Panel or Pump Disconnect Switch (shown in diagram).

11. Assemble the Gray connector to the wire going to the pump’s Pressure Switch.

12. Connect the SSWP to the new Blue and Gray connectors that were just wired.

13. Turn power on and check LED Indicator Sequence for proper startup and operation.

To install SoftStart Well Pump™ (SSWP) to 120VAC/15 or 20-amp power source, you must build a power cord with the supplied blue PowerCon twistlock connector and a 15-amp power plug.

1. Turn off all power to the pump. Never work on live circuits.

2. Find a good location to install SSWP with appropriate fasteners.

3. Obtain a NEMA 5-15P male plug (with 3 straight prongs – purchased separately).

4. Obtain 14- or 12-gauge cable to match pump HP size (see chart at left). If plugging into a generator, be sure cable length is long enough to keep generator exhaust way from living areas (max. 25-ft. length if possible).

5. Connect one end of cable wires to NEMA 5-15P male plug. See plug wiring diagram at left (Step 5).

6. Disassemble the BLUE PowerCon connector and connect the other end of power cable wires to BLUE PowerCon connector (shown below). See connector wiring diagram at left (Step 6).

7. Reassemble BLUE PowerCon connector.

8. Measure and cut a second length of power cable to run between SSWP location and the pump’s Pressure Switch.

9. Repeat procedures in Step 6 using the WHITE PowerCon connector (Step 9).

10. Connect other end of WHITE PowerCon connector cable to Pressure Switch.

11. Complete all other pump system electrical connections and test.

To install SoftStart Well Pump™ (SSWP) to 120VAC/30-amp source, you must build a power cord with the supplied blue PowerCon twistlock connector and a 3-prong, 30-amp twistlock plug.

1. Turn off all power to the pump. Never work on live circuits.

2. Find a good location to install SSWP with appropriate fasteners.

3. Obtain a NEMA L-5 30 male plug (with 3 curved prongs – purchased separately).

4. Obtain 14- or 12-gauge cable to match pump HP size (see chart at left). Be sure cable length is long enough to keep generator exhaust way from living areas (max. 25-ft. length if possible).

5. Connect one end of cable wires to NEMA L-5 30P male plug. See plug wiring diagram at left (Step 5).

6. Disassemble the BLUE PowerCon connector and connect the other end of power cable wires to BLUE PowerCon connector (shown below). See connector wiring diagram at left (Step 6).

7. Reassemble BLUE PowerCon connector.

8. Measure and cut a second length of power cable to run between SSWP location and the pump’s Pressure Switch.

9. Repeat procedures in Step 6 using the WHITE PowerCon connector (Step 9).

SoftStart Well Pump™ ensures you have steady flowing water from your water well, whether you're on grid power, or back-up power. It helps your pump start smoothly instead of with a hard jolt. It controls the power flow when your pump turns on, which helps stop breaker trips, excessive water pressure, and motor wear. This means less stress on your pump and a longer life for your system. It's designed to work with backup or portable generators. It lowers the startup power surge, so your generator doesn’t overload or shut down. It’s ideal for any home on well water. It’s a very easy installation, but we recommend consulting a qualified electrician for safety and electrical code requirements. The soft starter connects with basic line-in and line-out wiring, and comes with clear instructions. Installing it takes about 20 minutes once wiring is ready!
