3. Safety Instructions

Always adhere to the following safety guidelines to prevent injury and damage to the pump:

• Electrical Safety: Ensure the power supply matches the pump's voltage (12V DC or 24V DC). Incorrect voltage can cause severe damage or electrical shock. All electrical connections must be performed by a qualified professional and comply with local electrical codes.
• Grounding: The pump must be properly grounded to prevent electrical hazards.
• Water Only: This pump is designed for pumping clean water. Do not use it for flammable, corrosive, or abrasive liquids.
• Overheating: Do not run the pump dry. Ensure the pump is always filled with water during operation to prevent overheating and damage.
• Ventilation: Ensure adequate ventilation around the pump to facilitate proper cooling.
• Maintenance: Disconnect power before performing any maintenance or inspection.
• Children and Pets: Keep children and pets away from the pump during operation.

4.2 Mounting the Pump

1. Select a stable, level, and dry location for the pump, protected from direct sunlight and extreme weather.
2. Ensure sufficient space around the pump for ventilation and maintenance access.
3. Secure the pump to the mounting surface using appropriate fasteners through the base holes to minimize vibration.

4.3 Plumbing Connections

1. Connect the suction pipe to the water intake port and the discharge pipe to the outlet port. Ensure all connections are airtight to prevent air leaks, which can affect priming and pump performance.
2. Use appropriate thread sealant on all pipe connections.
3. Install a foot valve with a strainer at the end of the suction pipe in the water source to prevent debris from entering the pump and to maintain prime.

4.4 Electrical Connections

1. WARNING: Ensure the power source is disconnected before making any electrical connections.
2. Connect the pump to a DC power supply (12V or 24V, matching your pump model) using appropriately sized wiring.
3. Observe correct polarity: connect the positive (+) wire from the power source to the positive terminal on the pump, and the negative (-) wire to the negative terminal. Incorrect polarity will prevent the pump from operating or cause damage.
4. Ensure all connections are secure and protected from moisture.

4.5 Priming the Pump

The QB60 is a self-priming pump, but initial priming is crucial for proper operation.

1. Locate the water injection cock on the pump head (refer to Figure 2).
2. Unscrew the cap of the water injection cock.
3. Slowly fill the pump casing with clean water until it overflows from the injection cock.
4. Securely replace the cap of the water injection cock.
5. Ensure the discharge valve (if installed) is open to allow air to escape during priming.

5. Operating Instructions

5.1 Starting the Pump

1. After completing all installation steps and priming the pump, ensure all valves are in the correct position (suction valve open, discharge valve open).
2. Connect the pump to the appropriate DC power supply.
3. The pump should start immediately and begin drawing water. Listen for any unusual noises.
4. If the pump does not draw water within a few minutes, shut it off, re-check priming, and inspect for air leaks in the suction line.

5.2 Monitoring Operation

• Regularly check the pump for excessive vibration, noise, or overheating.
• Ensure a continuous supply of water to the suction side to prevent dry running.
• Monitor the discharge pressure and flow rate to ensure they meet your requirements.

5.3 Shutting Down the Pump

1. Disconnect the pump from its DC power supply.
2. If the pump will be out of use for an extended period, especially in freezing conditions, drain all water from the pump casing and pipes to prevent damage.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your SaiFfe QB60 pump.

• Cleaning: Periodically clean the exterior of the pump to prevent dust and debris buildup, especially around the cooling fan.
• Suction Strainer: Regularly inspect and clean the foot valve strainer to ensure unrestricted water flow and prevent debris from entering the pump.
• Connections: Check all plumbing and electrical connections for tightness and signs of wear or corrosion.
• Winterization: In areas subject to freezing temperatures, completely drain the pump and associated piping to prevent ice damage. Store the pump in a warm, dry place if possible.
• Impeller Inspection: If performance degrades, the impeller may need inspection for wear or blockages. This typically requires professional service.
