“00”–IFC Cartridge Circulators with Integral Flow Check
102-135
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.
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 pro-
tected, 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 instal-
lation 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 lubri-
cated 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.
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 elec-
trical shock.

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.
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.
