4. Installation

Proper installation is crucial for the performance and longevity of your circulator. Refer to local codes and a qualified professional for assistance.

4.1 Pre-Installation Checks

• Verify that the circulator's voltage and frequency match the electrical supply.
• Ensure adequate space for installation, maintenance, and ventilation.
• Inspect the circulator for any shipping damage.

4.2 Mounting and Piping

The circulator should be mounted in a horizontal position with the motor housing horizontal. Ensure the system is drained and depressurized before making connections.

• Install the circulator in the return line of the hydronic system, if possible, to maximize its lifespan by operating in cooler water.
• Use appropriate pipe fittings and sealants to ensure leak-free connections.
• The Integral Flow Check (IFC) is built into the circulator, eliminating the need for an external check valve.

4.3 Electrical Wiring

All electrical wiring must be performed by a qualified electrician in accordance with national and local electrical codes. Ensure the power supply is disconnected before wiring.

• Remove the wiring cover to access the terminal block.
• Connect the power supply wires (Line, Neutral, Ground) to the corresponding terminals.
• Secure all connections and replace the wiring cover.

4.4 Initial System Fill and Purge

After installation, fill the hydronic system and thoroughly purge all air. Air in the system can cause noise, reduce performance, and damage the circulator.

5. Operating Instructions

The Taco 0015E3-F2 is designed for simple operation with its three selectable settings.

5.1 Powering On and Initial Start-up

Once electrical connections are complete and the system is filled, restore power to the circulator. The unit will initiate its SureStart mode.

5.2 SureStart Automatic Unblocking and Air Purging Mode

Upon initial power-up or after a power interruption, the circulator will automatically enter SureStart mode. This mode helps to:

• Clear air from the pump volute.
• Unblock the rotor if it has been seized by debris during periods of inactivity.

The circulator will run through a series of short cycles to achieve this. This process is automatic and requires no user intervention.

5.3 Selecting Operating Settings

The 0015E3-F2 features three easy settings, typically selected via a switch or dial on the unit. Consult the product label for specific setting indicators.

• Setting 1 (Low): Suitable for smaller systems or zones requiring minimal flow.
• Setting 2 (Medium): General purpose setting for most residential hydronic applications.
• Setting 3 (High): For larger systems or zones with higher flow and head requirements.

Choose the setting that provides adequate flow for your system while minimizing energy consumption. Adjustments can be made based on system performance and comfort levels.

5.4 Status Indicator

The circulator includes a status indicator light (LED) that provides visual feedback on its operational status. Refer to the product label or specific documentation for the meaning of different light patterns (e.g., solid green for normal operation, flashing for error codes).

6. Maintenance

The Taco 0015E3-F2 circulator is designed for minimal maintenance. Regular system checks contribute to its longevity and efficient operation.

• System Water Quality: Maintain clean system water. The BIO Barrier feature helps protect the pump from contaminants, but poor water quality can still impact overall system health.
• Leak Checks: Periodically inspect all piping connections for leaks. Address any leaks promptly.
• Noise Monitoring: Listen for unusual noises from the circulator. Excessive noise may indicate air in the system or a mechanical issue.
• Power Disconnection: Always disconnect power before performing any maintenance or inspection on the circulator.
