007 Variable Speed -T Cast Iron Circulator Pump, 115V User Manual

1. Product Overview

The 007 Variable Speed -T Circulator Pump is an all-in-one solution designed for heating systems. It combines a microprocessor-based variable speed differential controller with the reliability of 00 Cartridge Circulators. This pump automatically adjusts its performance to match the system's BTU/hr output, conserving energy and eliminating velocity noise. It is ideal for systems where conditions may vary, such as zone valve systems or multi-zone radiant manifolds.

Key features include an integrated pump and control, included sensors, and an easy installation process. It is UL approved and features a snap-in PC board, replaceable LED status panel, and fuse protection. An optional Integral Flow Check (IFC) further increases system efficiency.

2. Installation and Setup

Proper installation is crucial for optimal performance and safety. It is recommended that installation be performed by a qualified professional.

2.1. Pre-Installation Checks

• Ensure the power supply is disconnected before beginning installation.
• Verify that the system piping is clean and free of debris.
• Confirm that the pump's voltage (115V) matches the electrical supply.

2.2. Mounting the Pump

The pump is designed for flanged connections. Ensure proper alignment and secure fastening to prevent leaks. The connection sizes supported are 3/4", 1", 1-1/4", and 1-1/2".

2.3. Sensor Installation

Attach the two included sensors directly to the supply and return lines of the system or zone. These sensors are critical for the pump's variable speed functionality, allowing it to measure the temperature differential (-T).

2.4. Electrical Connections

Connect the pump to a 115V, 60Hz, 1-phase power supply. The pump features plug-in low voltage wiring terminals for easy connection of the sensors and control signals. Ensure all electrical connections comply with local codes and regulations.

3. Operation

The 007 Variable Speed -T Circulator is designed for automatic, efficient operation once properly configured.

3.1. Setting the Temperature Differential (-T)

To operate the pump, simply dial in the desired temperature differential (-T) for your system or zone. This setting can range from 5°F to 50°F. The pump will then automatically adjust its performance to maintain this differential, optimizing heat transfer and energy consumption.

3.2. Automatic Adjustment

The circulator continuously monitors the system's actual operating conditions via the installed sensors. It automatically varies its speed and performance to deliver optimal heat based on the current load, even when conditions change. This ensures the pump always runs at the minimum required speed, eliminating velocity noise and conserving energy.

3.3. Pump Exercise Function

The pump includes a "Pump Exercise" feature which helps maintain the pump's readiness and extends its lifespan by periodically running it, even during periods of inactivity.

4. Maintenance

Regular maintenance ensures the longevity and efficient operation of your circulator pump.

4.1. Routine Checks

• Periodically inspect the pump for any signs of leaks around the flanges.
• Ensure the power supply connections are secure and free from corrosion.
• Listen for any unusual noises during operation, which may indicate an issue.

4.2. Replacement Parts

Should replacement parts be needed, the following are available:

• Casing O-Ring: 008-005RP
• Flange Gasket Set: 007-007RP
• Cartridge Assembly Complete: 007-042RP

The LED Status Panel is also replaceable.

5. Troubleshooting

This section provides guidance for common issues you might encounter.

5.1. Velocity Noise

The variable speed functionality of this pump is designed to eliminate velocity noise by running at the minimum required speed. If velocity noise is present, ensure the -T setting is appropriate for your system and that the sensors are correctly installed and functioning.

5.2. Inconsistent Heat Transfer

If the system is not achieving desired heat transfer, verify the -T setting. Check sensor connections and ensure they are accurately reading temperatures. The pump automatically adjusts to current system conditions, so ensure there are no external factors impeding flow or heat exchange.

5.3. Pump Not Running

• Check the power supply to the pump.
• Inspect the fuse on the PC board.
• Verify that the LED Status Panel is indicating normal operation.
• Ensure the pump exercise function is not the only reason for perceived inactivity during low demand.

For persistent issues, refer to the "Customer Support" section.
