1. Introduction and Overview
The Taco 007E-F2 is a high-efficiency wet rotor circulator designed for hydronic heating systems. It features an ECM (Electronically Commutated Motor) permanent magnet motor, providing performance equivalent to the standard 007 circulator while offering enhanced energy efficiency. This circulator is ideal for systems zoned with either circulators or zone valves. It is important to note that the 007E-F2 is not suitable for chilled water or open-loop potable water systems.
Figure 1.1: Taco 007E-F2 ECM High Efficiency Circulator. This image displays the Taco 007E-F2 ECM High Efficiency Circulator. The main unit is green and black, featuring the '007e ECM HIGH-EFFICIENCY CIRCULATOR' branding and a '00e series STATUS' indicator light. Below the main unit, two black rubber gaskets and a white integral flow check (IFC) component with green internal parts are shown.
2. Safety Information
Read all instructions carefully before installation and operation. Failure to follow these instructions may result in property damage, serious injury, or death.
- Electrical Hazard: Ensure power is disconnected at the main service panel before performing any electrical work. All wiring must comply with local electrical codes and regulations.
- Burn Hazard: The circulator pump and connected piping can become very hot during operation. Allow components to cool before handling.
- Pressure Hazard: Hydronic systems operate under pressure. Relieve system pressure before opening any connections.
- Qualified Personnel: Installation and servicing should only be performed by qualified and experienced personnel.
- Intended Use: Use this circulator only for its intended purpose in closed-loop hydronic heating systems. Do not use for potable water or chilled water applications.
3. Product Features
- High-Efficiency ECM Motor: Features an Electronically Commutated Motor for reduced energy consumption.
- Wet Rotor Design: Ensures quiet operation and eliminates the need for mechanical seals.
- Ideal for Hydronic Systems: Suitable for systems zoned with circulators or zone valves.
- Bio Barrier: Protects the pump from system contaminants, extending its lifespan.
- SureStart: Automatically frees locked rotor conditions and self-purges air from the pump, ensuring reliable startup.

5. Setup and Installation
Proper installation is crucial for the efficient and safe operation of your Taco 007E-F2 circulator. Always refer to the detailed installation instructions provided with the product packaging for specific diagrams and warnings.
- System Preparation:
- Ensure the heating system is depressurized and drained before beginning installation.
- Turn off all electrical power to the heating system at the main breaker.
- Mounting Location:
- Install the circulator in an accessible location, preferably on the return side of the boiler, to ensure cooler operating temperatures and longer life.
- Ensure the motor shaft is horizontal for optimal performance and lubrication.
- Piping Connections:
- Use the provided gaskets for a watertight seal.
- Ensure the flow direction arrow on the circulator body matches the system's flow. The pump housing can be rotated to accommodate various flow directions.
- Avoid overtightening connections to prevent damage.
- Electrical Wiring:
- Connect the circulator to a dedicated electrical circuit as per local codes.
- The 007E-F2 typically does not require a separate ground wire, but always verify with local electrical codes and the product's specific wiring diagram.
- Ensure all electrical connections are secure and protected from moisture.
- System Fill and Purge:
- After installation, slowly refill the hydronic system, ensuring all air is purged. The SureStart feature assists in self-purging air from the pump.
- Check for leaks at all connections.
6. Operating Instructions
Once installed and the system is filled, the Taco 007E-F2 circulator operates automatically based on the demands of your hydronic heating system.
- Initial Startup: After restoring power, the circulator will initiate its startup sequence. The SureStart feature will automatically attempt to free any locked rotor conditions and purge air.
- Status Indicator: Observe the status indicator light on the circulator. A steady light typically indicates normal operation. Refer to the product's specific manual for detailed indicator light codes.
- Quiet Operation: The wet rotor design and ECM motor contribute to very quiet operation. Minimal noise is expected during normal function.
- Energy Efficiency: The ECM motor continuously adjusts its speed to match system demand, optimizing energy consumption.
7. Maintenance
The Taco 007E-F2 circulator is designed for minimal maintenance. However, periodic checks can help ensure long-term reliability.
- Annual Inspection: Annually inspect the circulator and surrounding piping for any signs of leaks, corrosion, or unusual wear.
- System Water Quality: Maintain proper water quality in your hydronic system. The Bio Barrier feature helps protect the pump from contaminants, but good system hygiene is still important.
- Cleanliness: Keep the exterior of the circulator clean and free from dust or debris to ensure proper heat dissipation.
- No Lubrication Required: The wet rotor design means the motor is lubricated by the system fluid, eliminating the need for external lubrication.
8. Troubleshooting
This section addresses common issues you might encounter with your circulator. For complex problems, contact a qualified HVAC technician.
| Problem | Possible Cause | Solution |
|---|---|---|
