Instruction Sheet 102-135 “00”–IFC Cartridge Circulators with Integral Flow Check SUPERSEDES: December 15, 2008 EFFECTIVE: May 1, 2010 Plant ID# 001-1021 APPLICATION: 1. Maximum operating pressure is 125 psi (862 kPa). 2. Maximum water temperature not to exceed nameplate rating. 3. Cast iron circulators are to be used for closed loop systems. Bronze or Stainless Steel circulators are to be used for open loop, fresh water, or potable water systems. 4. Taco Cartridge circulator pumps are for indoor use only – employer uniquement a l´interieur. INSTALLATION: 1. Location – Install the “00”-IFC 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. CAUTION: If circulator is installed on the return line, purge valve must be placed on the pump discharge to allow proper purging of system air. See Figure 2. 2. Mounting position – Circulator must be mounted with the motor in a 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). 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 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. 5. Fill system with tap water – The system must be filled before operating the circulator. The bearings are water lubricated and should not be allowed to operate dry. Filling the system will result in immediate lubrication of the bearings. It is always good practice to flush a new system of foreign matter before starting the circulator. 6. Circulator operation – Operate the circulator for 5 minutes immediately after flushing the system to purge remaining air from the bearing chamber. This is especially important when installing the circulator during the off-season. WARNING: Do not use in swimming pool or spa areas; pump has not been investigated for this application. WARNING: In the event the retaining screws have been pulled out of the housing, DO NOT replace them. Use of any other screw may short out the stator windings, creating a risk of electrical shock. CAUTION: When installing electrical connections, do not apply mechanical loads to the capacitor box; otherwise, retaining screws may be pulled out of the housing, making circulator unusable. 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. CAUTION: 1. The addition of petroleum based fluids or certain chemical additives to systems utilizing TACO equipment voids the warranty. 2. Use supply wires suitable for 90°C – ATTENTION: Employer des fils d´alimentation adequats pour 90°C. WARNING: To avoid electrical shock, disconnect the power supply to the circulator and the main electrical unit.

PROPER REMOVAL/REPLACEMENT OF THE INTEGRAL FLOW CHECK (IFC) Your “00” circulator with an Integral Flow Check (IFC) is designed for easy removal, service and replacement. Please follow these instructions to ensure proper service and operation of the circulator. REMOVAL: 1. Disconnect power to circulator and related equipment. 2. Shut off water supply. Isolate circulator using service valves or drain system if valves are not available. 3.a For models listed in Figure 3 below, remove motor housing by loosening four cap screws. 3.b For models listed in Figure 4 below, loosen flange bolts and remove entire circulator from the system to access the IFC. 4. Using needle-nose pliers, carefully grip the IFC’s body and slowly remove the IFC. Note: If your IFC circulator has four channels as shown in Figure 3 below, turn the IFC 45° (clockwise or counter-clockwise). Position the four guide vanes half-way between the four channels, then slowly remove the IFC from the pump casing. The channels are designed to lock the IFC in place. Turning the valve 45° unlocks the valve for easy removal. REPLACEMENT: 1. Make sure the IFC pocket is clean and free of any debris or particulates. 2. Position IFC into the machined pocket inside the casing as shown in the diagrams below. Firmly press the IFC into the pocket until it snaps into place. Note: If your IFC circulator has four channels as shown in Figure 3 below, align the four guide vanes with the four channels as shown. Firmly press the IFC into the pocket until it snaps into place. 3. Replace O-ring and reattach motor housing; or reinstall entire circulator with new flange gasket. 4. Open water supply and refill system. Check for any leaks. 5. Reconnect power to circulator and check for proper operation of system.

Channels (4) Guide Vanes (4) • Turn 45˚ to remove • Align with (4) channels to install All Sweat, Union Mount or Old Style Flanged Models All New Style Flanged Models REPLACING MOTOR ASSEMBLY: 1. Disconnect the electrical supply. 2. Reduce system pressure to 0 psi and allow system to return to room temperature. Isolate the circulator by closing the service valves or draining the system. 3. Remove the body bolts and swing motor assembly away from the body. 4. Install new motor, and reassemble circulator using the new gasket and bolts supplied. 5. Follow the “installation” procedure to start up the circulator REPLACING CARTRIDGE ASSEMBLY: 1. Disconnect the electrical supply. 2. Reduce system pressure to 0 psi and allow system to return to room temperature. Isolate the circulator by closing the service valves or draining the system. 3. Remove the body bolts and swing motor assembly away from the body. 4. Pull cartridge out of the motor housing. 5. Install replacement cartridge, making sure that the cover plate is between the cartridge flange and motor. 6. Make sure the replacement cartridge corresponds to the full circulator product number. A complete parts list is available from your local plumbing supply wholesaler. 7. Reassemble the circulator using the new gasket and bolts supplied. 8. Follow the “Installation” procedure to start up the circulator. REPLACING CAPACITOR: 1. Replacement capacitor must have same rating as originally furnished.
