SUPERSEDES: November 2, 2015
The circulating pumps are used for the transfer of liquid media
1. GENERAL INFORMATION, USES:
within a closed-looped hot-water heating or air-conditioning
hydronic system. They are designed as single or parallel
main/standby operation variable-speed pumps, where the speed
is regulated by an on-board electronic device. They are to be used
with a water or glycol/water mixture.
These instructions should be studied carefully before installing or
2. SAFETY:
operating the pump. They are meant to help you with installation,
use and maintenance and to increase your safety. Installation
should be performed with regards to local or national standards.
Only qualified personnel should maintain and service these prod-
ucts. Failure to comply with safety precautions could cause per-
sonal injury or machinery damage.
WARNING: Do not use in swimming pool or spa
areas. Pump has not been investigated for these
applications.
AVERTISSEMENT: Ne pas utiliser dans une piscine
ou un spa. La pompe n'a pas été étudiée pour ces
applications.
WARNING: To avoid electrical shock, disconnect
the power supply to the circulator and the main
electrical unit. Follow all local electrical and
plumbing codes.
AVERTISSEMENT: Pour éviter tout choc électrique,
débranchez l'alimentation électrique vers le circu-
lateur et l'unité électrique principale. Respectez
tous les codes de plomberie et électriques locaux.
WARNING: Hot surfaces can cause burns. The
motor can also reach temperatures that could
cause injury.
AVERTISSEMENT: Les surfaces chaudes peuvent
provoquer des brûlures. Le moteur peut également
atteindre des températures qui peuvent entraîner
des blessures.
CAUTION: The addition of petroleum based fluids
or certain chemical additives to systems using
TACO equipment voids the warranty.
ATTENTION: L'ajout de liquides à base de pétrole
ou de certains additifs chimiques à des systèmes
utilisant un équipement TACO annule la garantie.
CAUTION: Use supply wires suitable for 90°C.
ATTENTION: Employer des fils d'alimentation
adeqauts pour 90°C.
CAUTION: Misconnection or overload of electrical
or signal connections could cause pump to shut-
down or cause permanent damage.
ATTENTION: Toute erreur de raccordement ou sur-
charge des connexions électriques ou de signali-
sation peut entraîner un arrêt de la pompe ou des
dommages permanents.

(-1 and -2 Models)
The high efficiency, electronically commutated 00e pumps consist
3. PUMP DESCRIPTION:
of two main parts, the centrifugal pump and the electronic regulator.
The hydraulic part is hermetically sealed from the motor assembly
and has no mechanical seals. 00e pumps are powered by an ECM
permanent magnet motor which does not consume energy to mag-
netize the rotor, providing superior energy efficiency.
The ECM motor is run by an on-board frequency converter with an
integrated PFC (Power Factor Correction) filter. The converter
estimates current flow and head from the motor load, information
essential for differential pressure control.
The 00e™ pump is protected with a double box during shipping. It
4. PUMP INSTALLATION:
can be lifted from the box with internal handles or by lifting it by the
heat sink.
Pumps are designed to be installed using standard ANSI class
125 flanges. It is recommended that the 00e pumps be installed
with at least 5 to 10 pipe diameters of straight pipe on the inlet and
outlet of the pump. Use all nuts and bolts to attach companion
flanges to the pump flanges. For pumps to operate with minimal
vibration and noise, it should be installed with the axis in a hori-
zontal position (see Figure 1).
Desired head orientation can be achieved by rotating the pump
head. The pump is mounted to the volute with four screws. By
unscrewing those the head can be turned. Caution: When
ring and insuring a tight seal. For replacement O-rings, use part reassembling, care should be taken to avoid damaging the O-
number 975-001RP. See detailed Motor Rotation Procedure 4.1
below.
CAUTION: Do not operate pump without the electri-
cal cover securely attached.
ATTENTION: Ne pas actionner la pompe si le cou-
vercle électrique n'est pas correctement fixé.
CAUTION: Pump motor, electronics enclosure and
condensate drain openings should not be thermally
insulated as it could interfere with cooling and
condensate drainage.
ATTENTION: Le moteur de pompe, l'enceinte élec-
tronique et les ouvertures de drainage de condensat
doivent être thermiquement isolés car il peut y avoir
interférence avec l'évacuation de condensat et de
liquide de refroidissement.
CAUTION: Pump may be heavy. Provide yourself
help if needed.
ATTENTION: La pompe est lourde. Veillez à deman-
der de l'aide si nécessaire.
