“00” Cartridge Circulators
102-054
SUPERSEDES: 102-054 dated April 15, 2004 EFFECTIVE: May 1, 2010
Plant I.D. 001-934
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. 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 pressure is at least 20 psi (138 kPa).
2. 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.)
3. 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.
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: 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.
WARNING: To avoid electrical shock, disconnect the power supply to the circulator and the main
electrical unit.
4. 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.
5. Circulator operation – Operate the circulator for 5 minutes immediately after filling system to purge remaining air from
the bearing chamber. This is especially important when installing the circulator during the off-season.
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.
