Setup and Installation
Proper installation is crucial for the pump's performance and longevity. Consult a qualified professional if you are unsure about any steps.
1. Choosing the Right Well Type
This pump is convertible for both shallow and deep well applications. The choice depends on your well's depth.
- Shallow Well (0-25 ft): Uses a single pipe system.
- Deep Well (26-90 ft): Requires the included ejector kit and a two-pipe system.
Figure 4: Well Depth and Ejector Installation Guide. This diagram helps determine the correct setup based on your well's depth.
2. Electrical Connection and Voltage Selection
The pump is factory-set for 230V. If your power supply is 115V, you must adjust the voltage selector switch located inside the power box.
Figure 5: Dual Voltage Selection. The switch is located within the electrical housing. Ensure power is disconnected before making any changes.
- Disconnect Power: Ensure the pump is unplugged or the circuit breaker is off.
- Access Switch: Open the cover of the power box.
- Select Voltage: Locate the voltage selector switch. Move it to the appropriate position (down for 115V, up for 230V).
- Secure Cover: Close and secure the power box cover.
CAUTION: Failure to select the correct voltage can damage the pump and void the warranty.
3. Plumbing Connections
- Use appropriate NPT fittings for the suction (1-1/4" and 1") and discharge (1") ports.
- Ensure all connections are airtight to prevent air leaks, which can affect pump performance. Use thread sealant tape or pipe dope.
- Install a check valve in the suction line to maintain prime.
- For deep well installations, connect the ejector kit according to the provided diagrams, ensuring the two pipes are correctly routed to the well.
Operating Instructions
1. Priming the Pump
Before initial startup or after the pump has been drained, it must be primed with water.
Figure 6: Priming the Pump. This visual guide demonstrates the two steps for proper pump priming.
- Locate Priming Port: Identify the priming port on top of the pump housing.
- Unscrew Cap: Carefully unscrew the priming port cap.
- Fill with Water: Slowly pour clean water into the priming port until the pump casing and suction line are completely filled.
- Replace Cap: Securely replace the priming port cap.
- Start Pump: Connect power to the pump. The pump should begin to draw water.
2. Automatic Pressure Switch Operation
The integrated automatic pressure switch controls the pump's operation to maintain water pressure in your system.
- The pump will automatically start when the system pressure drops below 20 PSI.
- The pump will automatically shut off when the system pressure reaches 35 PSI.
- This ensures consistent water supply without manual intervention.
3. Overheat Protection
The pump features a built-in automatic thermal overload protector. If the motor overheats due to prolonged use, low voltage, or dry running, it will automatically shut off to prevent damage. The pump will restart once it has cooled down.
Figure 7: Automatic Thermal Overload Protector. This feature safeguards the motor from damage due to excessive heat.
Maintenance
Regular maintenance ensures optimal performance and extends the life of your pump.
1. General Care
- Keep the pump clean and free from debris.
- Periodically check all connections for leaks and tighten as necessary.
- Inspect the power cord for any signs of damage.
2. Winterization (for cold climates)
If the pump is installed in an area subject to freezing temperatures, it must be properly winterized to prevent damage.
- Disconnect Power: Turn off the power supply to the pump.
- Drain Pump: Open the drain plugs on the pump casing to completely drain all water.
- Drain Piping: Drain all water from the suction and discharge piping.
- Store Ejector (Deep Well): If using a deep well ejector, ensure it is also drained or removed if possible.
- Protect Pump: Store the pump in a warm, dry location, or insulate it thoroughly if it must remain in place.
