Safety Information
Always observe local codes and regulations during installation and operation. Disconnect power before servicing. Ensure proper grounding. This pump is designed for closed heating systems; do not use for potable water applications unless specifically rated for such use.
Setup and Installation
Proper installation is crucial for optimal performance and longevity of the pump. Refer to the official Grundfos UP Series Product Guide for detailed diagrams and instructions.
Pre-Installation Checks:
- Verify that the system is depressurized and drained.
- Ensure the power supply matches the pump's requirements (115V, 60Hz, 1 Phase).
- Confirm that the installation location allows for proper motor orientation (horizontal position is generally recommended).
- Inspect the pump and included gaskets for any damage.
Mounting:
- Position the pump in the system, ensuring the motor is mounted horizontally. The rotated flange design offers flexibility for alignment.
- Use the provided gaskets (O-rings) between the pump flanges and system piping.
- Secure the pump using appropriate flange connections (1/2", 3/4", 1", 1-1/4" compatible).
Electrical Connection:
- Ensure the main power supply is disconnected.
- Connect the pump to a 115V, 60Hz, single-phase electrical supply.
- Follow all local electrical codes and wiring diagrams provided in the full product documentation.
- Ensure proper grounding to prevent electrical hazards.
Operating Instructions
The Grundfos UPS15-58FRC features a three-speed selector switch to adjust pump performance based on system requirements.
Initial Startup:
- After installation, slowly refill the system with fluid, ensuring all air is purged.
- Check for leaks at all connections.
- Restore power to the pump.
- Select the desired speed setting using the selector switch on the pump motor.
Speed Settings:
The pump offers three distinct speed settings, allowing for optimization of flow and head for various system demands. Refer to the specifications section for amperage and wattage at each speed.
- Speed 1 (Low): For systems requiring minimal flow or head.
- Speed 2 (Medium): A balanced setting for general heating applications.
- Speed 3 (High): For systems demanding maximum flow and head.
The wet rotor design ensures quiet operation during all speed settings.
Maintenance
The Grundfos UPS15-58FRC is designed for minimal maintenance due to its wet rotor construction and built-in motor protection.
Routine Checks:
- Periodically inspect the pump for any signs of leaks around the connections.
- Listen for unusual noises during operation, which could indicate a problem.
- Ensure the motor housing is free from excessive dust or debris to maintain proper cooling.
Cleaning:
No internal cleaning is typically required. For external cleaning, wipe the pump with a damp cloth. Do not use abrasive cleaners or solvents.
Winterization:
If the system is to be shut down for an extended period in freezing temperatures, ensure the system is properly drained or filled with an appropriate antifreeze solution to prevent damage to the pump and piping.
Troubleshooting
This section provides guidance for common issues. For complex problems, consult a qualified technician or Grundfos support.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start. | No power supply; tripped circuit breaker; motor protection activated; seized impeller. | Check power connections and circuit breaker. Allow motor to cool if protection activated. Consult technician if impeller is seized. |
| Pump runs but no flow or low flow. | Air in system; closed isolation valves; clogged impeller; incorrect speed setting. | Bleed air from the system. Ensure all valves are open. Check for obstructions. Adjust speed setting. |
| Unusual noise or vibration. | Air in system; cavitation; foreign object in pump; improper mounting. | Bleed air. Ensure adequate system pressure. Inspect for debris. Verify pump is securely mounted horizontally. |
| Leakage at connections. | Loose connections; damaged gaskets. | Tighten connections. Replace gaskets if damaged. |
