INSTALLATION:
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.
CAUTION: The addition of petroleum based uids or certain chemical additives to systems usingTACO equipment
voids the warranty. Consult factory for uid compatibility.
ATTENTION : L’ajout de liquides à base de pétrole ou de certains additifs chimiques à des systèmes utilisant un
équipement TACO annule la garantie. Consultez le fabricant pour connaître la compatibilité de liquides.
CAUTION: Installations at elevations over 5000 feet must have higher ll pressure of 20 psi minimum to prevent
pump cavitation and ashing. Premature failure may result. Adjust expansion tank pressure to equal ll pressure.
A larger size expansion tank may be required.
ATTENTION : Des installations à des altitudes de plus de 1600 mètres doivent présenter une pression de remplissage
plus élevée de 20 psi
au minimum an d’éviter toute cavitation ou ashing de la pompe. Une défaillance prématurée peut en résulter. Réglez la pression
du réservoir d’expansion de façon qu’elle soit égale à la pression de remplissage. Un réservoir d’expansion d’une taille supérieure
peut être nécessaire.

1. Location: The circulator can be installed on the supply or return side of the boiler but for best system
performance, it should always pump away from the expansion tank. See piping diagrams in Figure 2 & Figure 3.
NOTE:Two shorter 1-1/4”x 7/16”ange bolts are provided with the circulator to
use on the discharge ange to prevent interference with the circulator casing.
CAUTION: Do not use at rubber gaskets. Only use O-ring gaskets provided or leaks may result.Warranty will be void.
2. Mounting position: Circulator must be mounted with the motor in the horizontal position. See Figure 4 & Figure 5
below for acceptable and unacceptable motor mounting orientations. See Figure 6 for Rotating Control Cover.
CAUTION: To reduce the possibility of noise transmission, be sure to add vibration dampeners to piping when mounting
circulator to wall or oor joists.
ATTENTION : Pour réduire la possibilité de transmission de bruit, veillez à ajouter des amortisseurs de vibration à
la tuyauterie lors du montage du circulateur sur des chevêtres de mur ou de plancher.
3. Filling the system: Fill the system with tap water or a maximum of 50% propylene-glycol and water solution.
The system must be lled 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 ush a new system of foreign matter before starting the circulator.
WARNING: Risk of electric shock. To reduce the risk of electric shock, be certain that it is connected only to a properly
grounded, grounding-type receptacle. Follow all local electrical and plumbing codes.
AVERTISSEMENT : Risque de choc électrique. Pour réduire le risque de choc électrique, veillez à ce qu’elle soit raccordée uniquement
à un réceptacle de type mise à la terre proprement mis à la terre. Respectez tous les codes de plomberie et électriques locaux.
WARNING: Use supply wires suitable for 90°C.
AVERTISSEMENT : Employer des ls d’alimentation adeqauts pour 90°C.
WARNING: Disconnect power when servicing.
AVERTISSEMENT : Couper l’alimentation lors de l’entretien.
CAUTION: Use exible conduit only. Not for use with rigid conduit.
ATTENTION : N’utiliser que du conduit exible ; n’est pas fait pour du conduit rigide.

WARNING: SERVICING OF DOUBLE-INSULATED APPLIANCES. A double-insulated appliance is marked with one or more of the
following: The words“DOUBLE INSULATION”or“DOUBLE INSULATED”or the double insulation symbol (square within a square).
In a double-insulated appliance, two systems of insulation are provided instead of grounding. No grounding means is provided on
a double-insulated appliance, nor should a means for grounding be added. Servicing a double-insulated appliance requires extreme
care and knowledge of the system, and should be done by qualied service personnel. Replacement parts for a double-insulated
appliance must be identical to the parts they replace.
AVERTISSEMENT : ENTRETIEN DES APPAREILS À DOUBLE ISOLATION. Un appareil à double isolation est marqué avec un ou plusieurs
des éléments suivants : les mots « DOUBLE INSULATION » ou « DOUBLE INSULATED » ou le symbole de double isolation (carré dans
un carré). Dans un appareil à double isolation, deux systèmes d’isolation sont fournis plutôt que la mise à la terre ; aucun moyen
de mise à la terre n’est fourni ni ne doit être ajouté. L’entretien d’un appareil à double isolation exige de grandes précautions et
une connaissance approfondie du système, et doit être eectué par un technicien qualié. Les pièces de rechange pour un
appareil à double isolation doivent être identiques aux pièces remplacées.
4. Wiring the circulator: Disconnect AC power supply. Remove terminal box cover. Attach a wiring connector into knockout
hole. Use exible conduit only. The green terminal plug may be removed to simplify wiring, then snapped back in place.
Connect Line/Hot power to the L terminal, Neutral to the N terminal and Ground to the G terminal. See wiring diagram
above. The 0034ePlus is a double insulated circulator; grounding wire is not necessary but recommended for safety.
Replace terminal box cover. Insert rubber cap plug provided to cover unused knockout hole.
4a. Wiring the circulator for 0-10V DC Operation: (See Page 10)
5. Start the circulator: When purging the system, it is recommended to run the circulator at full speed long
enough to remove all remaining air from the bearing chamber. This is especially important when installing
the circulator in the o-season. Set operating mode to Fixed Speed on 100% HIGH setting for maximum
xed speed. A blue LED will illuminate when the 0034ePlus is powered on.
CAUTION: Never run the circulator dry or permanent damage may result.
ATTENTION: Ne laissez jamais le circulateur tourner à sec, des dommages permanents peuvent en résulter.
Full Speed Operation:
To run the pump at full speed during the fast ll, start-up and purge process, set operating mode to Fixed Speed on
100% HIGH setting. (See “Programming your 0034ePlus Circulator”). The LED will change to blue. To return to the normal
operating mode, reset operating mode to desired activeADAPT, Constant Pressure, Proportional Pressure, Fixed Speed
or 0-10V setting.

6. Programming your 0034ePlus circulator:
Modify the performance of the circulator as needed by changing the
operating mode using the easy programming button keypad. When the circulator is powered on, the LED will illuminate
and change color based on the operating mode selected. The LED will ash each time a setting is changed.
See diagram below to set pump for desired operating mode. The selection of the right operating curve
depends on the characteristics of the system and the actual ow / head requirements. See Pump Curves to
determine the best operating mode for the system. See cross-reference replacement chart on back page.
The 0034ePlus has 5 Operating Modes:
• activeADAPT™ — Automatic, self-adjusting, proportional pressure, variable speed
(Violet LED)
• Constant Pressure — 5 curve settings of constant pressure, variable speed
(Orange LED)
• Proportional Pressure — 5 curve settings of proportional pressure, variable speed
(Green LED)
• Fixed Speed — Variable xed speed settings (1 - 100%)
(Blue LED)
• 0-10V DC — Analog external input or PWM pulse width modulation
input from building control system, variable speed
(Yellow LED)
