Important Safety Instructions

Failure to follow these instructions may result in electric shock, fire, serious injury, or death.

• Electrical Safety: Ensure the pump is connected to a properly grounded 115V AC outlet. Do not operate with damaged cords or plugs. Avoid using extension cords unless absolutely necessary and ensure they are rated for outdoor use and the pump's power requirements.
• Water and Moisture: Do not immerse the pump in water. Keep electrical connections dry. Operate the pump in a well-ventilated area, protected from rain and direct sunlight.
• Priming: This pump is not self-priming. It requires manual priming with water before initial use and after any period of dry operation to prevent motor damage. Ensure the foot valve is properly installed.
• Overheat Protection: The pump features built-in thermal overload protection. If the motor overheats or runs dry, it will automatically shut off. Allow the pump to cool down and address the cause of overheating before restarting.
• Children and Pets: Keep children and pets away from the pump during operation.
• Maintenance: Disconnect power before performing any maintenance or service.

Product Overview

The Acquaer SJS150-SA is a robust shallow well pump designed for various water transfer and irrigation applications. It features a powerful 1.6 HP motor, a stainless steel casing, and an integrated pressure tank for consistent performance.

Key Features:

• Powerful Motor: 1.6 HP motor provides high flow (up to 1320 GPH) and pressure (Max. Head 164ft) with strong suction (up to 26ft).
• Durable Construction: Stainless steel casing and aluminum motor housing ensure corrosion resistance and longevity.
• Integrated Pressure Tank: Reduces motor start-ups, extending service life and providing stable water pressure.
• Automatic Operation: Features an automatic pressure switch (Auto On < 20 psi, Auto Off > 40 psi) and a pressure gauge for real-time monitoring.
• Safety Features: Built-in thermal overload protection and a waterproof On/Off switch.
• Easy Installation: 1" NPT discharge and suction ports, compatible with 3/4" garden hose adapter.

Installation and Setup

1. Choose a Location: Place the pump on a stable, level surface in a dry, well-ventilated area, protected from freezing temperatures and direct weather exposure. Ensure adequate space for ventilation and maintenance.
2. Connect Suction Line: Attach a 1-inch NPT suction pipe to the pump's inlet. It is crucial to install a foot valve at the end of the suction line, submerged in the water source, to prevent backflow and maintain prime. Ensure all connections are airtight to prevent air leaks.
3. Connect Discharge Line: Attach a 1-inch NPT discharge pipe to the pump's outlet. You may use the provided 3/4" garden hose adapter if connecting to a standard garden hose.
4. Priming the Pump: Before initial operation, the pump must be primed. Remove the priming plug (usually located on top of the pump housing) and fill the pump casing completely with water until it overflows. Replace the priming plug securely. This step is critical for the pump to function correctly.
5. Electrical Connection: Plug the pump's 115V power cord into a grounded electrical outlet. Ensure the power supply matches the pump's voltage requirements.

Figure 6: Visual guide for pump priming and operation. This diagram illustrates the correct method for priming the pump before use, ensuring the suction line is submerged, and the proper functioning during and after use.

CAUTION: A check valve must be installed at the inlet pipe to prevent water from flowing back and losing prime.

Operation

1. Initial Start-up: After ensuring the pump is properly primed and all connections are secure, turn on the power switch. The pump will begin to draw water.
2. Automatic Pressure Control: The integrated pressure switch will automatically turn the pump ON when the system pressure drops below 20 psi and turn it OFF when the pressure reaches approximately 40 psi. This maintains consistent water pressure.
3. Monitor Pressure: Observe the pressure gauge to ensure the pump is operating within expected pressure ranges.
4. Thermal Overload: If the pump runs continuously without water (dry running) or experiences an overload, the thermal protection will activate, shutting down the motor. Allow the motor to cool down, identify and resolve the issue (e.g., re-prime, check for blockages), then restart.

Maintenance

Regular maintenance ensures the longevity and optimal performance of your Acquaer pump.

• Disconnect Power: Always disconnect the pump from the power source before performing any maintenance.
• Check for Leaks: Periodically inspect all connections for leaks. Tighten fittings as necessary.
• Clean Inlet Screen: If your suction line has a screen, check and clean it regularly to prevent blockages.
• Winterization: In areas subject to freezing temperatures, drain all water from the pump and piping to prevent damage. Store the pump in a warm, dry location if possible.
• Pressure Tank Check: Periodically check the air pre-charge in the pressure tank. Refer to the tank's specific instructions for proper pressure settings.
