CAUTION: Installations at higher elevations over 5000 feet must have higher fill pressure of 20 psi

minimum to prevent pump cavitation and flashing. Premature failure may result. Adjust

expansion tank pressure to equal fill pressure. A larger size expansion tank may be required.

INSTALLATION:

1. Location – Install the

“OO” circulator on the supply side of the boiler “pumping away” from the expansion tank as shown in

Figure 1. This is the best pump location for optimum system performance and maintaining positive system pressure. An alter-

nate location is on the boiler return line as shown in Figure 2.

2. Mounting position – Mount circulator with the motor in the horizontal position. It may be mounted vertically with the

motor up, provided that the system cold fill pressure is at least 20 psi (138 kPa) to ensure proper air purging and pre-

vent flashing.

3. Rotating body – Body has an arrow on the front that indicates direction of flow. To rotate body, remove the four body

bolts, rotate body and replace bolts. Make sure that the junction box is NOT located underneath the circulator. (The

junction box must NOT be located in the 6 o’clock position, as viewed from the motor end.)

4. Electrical connections – Observe all applicable codes when connecting to power supply.

The motor is impedance protected, and does not require additional overload protection.

Either colored wire from the capacitor box can be attached to either colored wire from the

power supply. There is no “hot” or “common” wire leading from the capacitor box. Typical

installation would be to attach the white wire to the white (common) power supply wire and

either the yellow or blue wire to the black (hot) power supply wire. The pump cannot run

backwards.

Do you have a question about the Taco 0010-MSF-IFC and is the answer not in the manual?

The Taco 0010-MSF-IFC Multi-Speed Cartridge Circulator, also known as the "Service Pump," is designed to replace most commonly used circulators in closed-loop heating systems. It features an integral flow check and a 4-bolt universal flange, making it a versatile component for hydronic applications.

Function Description:

This circulator pump is primarily used to circulate water within a closed-loop heating system, ensuring efficient heat distribution. The "Service Pump" designation indicates its role as a general replacement for various circulator models. Its multi-speed capability allows for adjustment of flow and performance to match system requirements, optimizing energy consumption and comfort. The integral flow check (IFC) prevents gravity circulation when the pump is off, which helps maintain system efficiency and prevents unwanted heat migration.

Important Technical Specifications:

Maximum Operating Pressure: 125 psi (862 kPa). This specifies the highest pressure the circulator can safely withstand during operation.
Maximum Water Temperature: Not to exceed the nameplate rating. Users must consult the specific nameplate on the device for the exact maximum temperature.
Application: Designed for closed-loop systems only. It is explicitly stated that cast iron circulators are for closed-loop systems.
Installation Environment: For indoor use only. The manual emphasizes "employer uniquement a l'interieur," meaning "for indoor use only."
Electrical Data (60 Hz Performance):
- Speed 1 (Low): 0.57 Amps (62 Watts)
- Speed 2 (Medium): 0.79 Amps (88 Watts)
- Speed 3 (High): 0.91 Amps (109 Watts) These values indicate the power consumption and current draw at different operating speeds, allowing users to assess energy usage.
Plant ID#: 001-3904. This is a specific identifier for the product.
Supersedes: May 1, 2010. This indicates that this manual updates previous versions.
Effective Date: July 15, 2014. This is the date from which the current manual's specifications and instructions are valid.

Usage Features:

Multi-Speed Control: The circulator features a speed dial (Figure 3 in the manual) that allows users to select between three speeds (Low, Medium, High) to match the desired flow and performance range for the system. This adaptability helps in optimizing system efficiency and comfort.
Integral Flow Check (IFC): The built-in IFC simplifies installation by eliminating the need for an external check valve. It is designed for easy removal, service, and replacement, as detailed in the "Proper Removal/Replacement of the Integral Flow Check (IFC)" section.
Mounting Position: The circulator should be mounted with the motor in the horizontal position. Vertical mounting with the motor up is permissible, provided the system cold fill pressure is at least 20 psi (138 kPa) to ensure proper air purging and prevent flashing.
Rotating Body: The body has an arrow indicating the direction of flow. It can be rotated by removing four body bolts, rotating the body, and then replacing the bolts. It's crucial to ensure the junction box is not located underneath the circulator (not in the 6 o'clock position from the motor end).
Piping Recommendations: The manual provides preferred piping diagrams (Figure 1 and Figure 2) for circulators on both the boiler supply line ("pumping away" from the expansion tank) and the boiler return line. The "pumping away" configuration is recommended for optimum system performance and positive system pressure.
Purging Steps: Detailed recommended purging steps are provided to ensure all air is removed from the system, which is critical for efficient operation and to prevent issues like pump cavitation.
Electrical Connections: The motor is impedance protected and does not require additional overload protection. Wiring instructions specify connecting either colored wire from the capacitor box to either colored wire from the power supply, with no "hot" or "common" wire from the capacitor box. The pump cannot run backward.
High Elevation Installations: For installations at elevations over 5000 feet, a higher fill pressure of 20 psi minimum is required to prevent pump cavitation and flashing. This may also necessitate a larger expansion tank.

Maintenance Features:

System Filling: The system must be filled with tap water before operating the circulator. Bearings are water lubricated and should not operate dry. Flushing a new system of foreign matter before starting the circulator is recommended.
Initial Operation: After flushing and filling, operate the circulator for 5 minutes to purge any remaining air from the bearing chamber, especially important during off-season installations.
Gasket Usage: Only O-ring gaskets provided with the circulator should be used on pump flanges. Using flat rubber gaskets will void the warranty and likely result in leaks.
IFC Removal and Replacement: The IFC is designed for easy removal using needle-nose pliers and replacement by pressing it into the machined pocket until it snaps into place. This facilitates cleaning or replacement of the IFC.
Motor Assembly Replacement: The motor assembly can be replaced by disconnecting power, reducing system pressure, isolating the circulator, removing body bolts, transferring the impeller cartridge, and then installing the new motor with new gaskets and bolts.
Cartridge Assembly Replacement: Similar to motor replacement, the cartridge assembly can be replaced by disconnecting power, reducing system pressure, isolating the circulator, removing body bolts, pulling the cartridge from the motor housing, and installing a new cartridge with new gaskets and bolts. It's crucial to ensure the replacement cartridge matches the full circulator product number.
Capacitor Replacement: If the capacitor needs replacement, it must have the same rating as the original.
Warranty: Taco, Inc. offers a three-year limited warranty from the date of manufacture for defects under normal use. The warranty is voided by the addition of petroleum-based fluids or certain chemical additives to the system, misuse, misapplication, or non-conformity with Taco instructions.

Safety Warnings and Cautions:

No Swimming Pool/Spa Use: The pump has not been investigated for swimming pool or spa applications.
Retaining Screws: If retaining screws are pulled out of the housing, they must NOT be replaced with any other screw, as this could short out stator windings and create an electrical shock risk.
Capacitor Box: Do not apply mechanical loads to the capacitor box during electrical connections, as this can pull out retaining screws and render the circulator unusable.
Petroleum-Based Fluids/Chemical Additives: The addition of petroleum-based fluids or certain chemical additives voids the warranty.
Supply Wires: Use supply wires suitable for 90°C.
Electrical Shock: Always disconnect power to the circulator and the main electrical unit before performing any work to avoid electrical shock.
Scalding: Allow the system to cool to prevent scalding before loosening flange bolts or performing maintenance.
