Setup and Installation
Proper installation is crucial for the optimal performance and longevity of the circulator pump.
Pre-Installation Checklist:
- Verify that the power supply matches the pump's requirements (110 Volts).
- Ensure adequate space for installation and future maintenance.
- Inspect the pump for any shipping damage.
- Gather necessary tools and materials (wrenches, pipe sealant, etc.).
Installation Steps:
- Isolate the System: Turn off the main power to the heating/cooling system and close isolation valves to drain the section where the pump will be installed.
- Mount the Pump: Install the circulator in the piping system. Ensure the flow direction arrow on the pump body aligns with the system's flow. The pump can be installed horizontally or vertically, but the motor should not be below the pump housing.
- Connect Piping: Use appropriate fittings and pipe sealant to connect the pump to the system piping. Avoid overtightening.
- Electrical Connections: Connect the pump to a dedicated electrical circuit according to local electrical codes. Ensure proper grounding. Refer to the wiring diagram on the motor housing.
- Fill and Vent: Slowly refill the system, ensuring all air is purged from the pump and piping. Open any air vents.
- Check for Leaks: Inspect all connections for leaks before restoring full power.
Operating Instructions
Once installed and the system is filled and vented, the circulator is ready for operation.
- Initial Start-up: Restore power to the system. The pump should start operating. Listen for unusual noises.
- Monitor Performance: Observe the system's heating/cooling performance. The circulator should operate smoothly and quietly.
- Continuous Operation: The Taco 110 circulator is designed for continuous duty in appropriate applications.
Note:
- Do not run the pump dry. Ensure the system is always adequately filled with fluid.
- The pump is designed to circulate water or water/glycol solutions. Do not use with other fluids without consulting the manufacturer.
Maintenance
Regular maintenance ensures the longevity and efficient operation of your circulator pump.
Annual Maintenance:
- Lubrication: The motor may require periodic lubrication. Refer to the motor label for specific lubrication instructions and frequency.
- Inspect for Leaks: Check all pipe connections and the pump housing for any signs of leaks.
- Check for Noise/Vibration: Listen for any unusual noises or excessive vibration, which could indicate a problem.
- System Fluid Quality: Ensure the system fluid is clean and free of debris.
Disassembly and Reassembly (for qualified personnel only):
The three-piece design allows for easy servicing of the motor and impeller assembly without disturbing the piping. Consult a qualified technician for internal component maintenance.
Troubleshooting
This section provides solutions to common issues you might encounter.
| Problem | Possible Cause | Solution |
|---|---|---|
| Pump does not start | No power; tripped breaker; faulty wiring; seized motor. | Check power supply and breaker. Verify wiring. Consult a technician if motor is seized. |
| Pump runs but no flow | Air in system; closed valves; clogged impeller. | Vent air from system. Open all isolation valves. Inspect impeller for obstructions. |
| Excessive noise or vibration | Air in system; cavitation; worn bearings; improper mounting. | Vent air. Ensure adequate system pressure. Check mounting. Consult technician for worn bearings. |
| Leaking from pump | Loose connections; worn seals. | Tighten connections. Replace seals if necessary (professional service recommended). |
