Taco 00R-MSF-IFC User Manual

Instruction Sheet

00R-MSF-IFC Multi-Speed Cartridge Circulator

with Integral Flow Check

102-226

APPLICATION:

• Maximum operating pressure is 125 psi (862 kPa).

• Maximum water temperature not to exceed nameplate rating.

• Cast iron circulators are to be used for closed loop systems only.

• Taco Cartridge circulator pumps are for indoor use only – employer uniquement
a l´interieur.

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.

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.

Plant ID# 001-3899

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 alter­nate 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 pre­vent 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 thermally 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.

9. ADJUST SYSTEM TO DESIRED
OPERATING FILL PRESSURE IF
REQUIRED

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.

7. Turn speed dial on circulator to the desired speed and performance range. See Figure 3.

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. Allow system to cool to prevent scalding. Loosen flange bolts
slowly to relieve system pressure and remove circulator from
the system. Access the IFC located in the discharge flange
(Figure 4).

4. Using needle nose pliers, carefully grip the IFC body and
remove slowly.

REPLACEMENT:

1. Make sure the IFC pocket is clean and free of any debris.

2. Position IFC into the machined pocket inside the casing as shown in Figure 4. Firmly press the IFC into the pocket until
it snaps into place.

3. Reinstall circulator with new flange gaskets, if required.

4. Open water supply and refill system. Check for any leaks.

5. Reconnect power to circulator and check for proper operation of system.

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. Transfer impeller cartridge from old motor to new motor making sure the cover plate is between the cartridge flange

and motor housing.

5. Install new motor, and reassemble circulator using the new gasket and bolts supplied.

6. 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.
