A Taco Family Company
SUPERSEDES: New
Plant ID No. 001-4276
DESCRIPTION:
The 0015e3 is a variable speed high-efficiency, wet rotor circulator with an ECM, permanent
magnet motor. With 3 easy settings, its performance curves are equivalent to the versatile Taco
0015 3-speed and ideal for hydronic systems zoned with circulators or zone valves. The 0015e3
reduces power consumption by up to 85% compared to equivalent AC permanent split capacitor
circulators.
APPLICATION:
• Maximum operating pressure: 125 psi (8.6 bar)
• Maximum water temperature: 230°F (110ºC)
• Electrical specifications:
Voltage: 110-120V, 50/60 Hz, single phase
Maximum operating power: 44W
Maximum amp rating: 0.54
• Equipped with a cast iron casing and should be used for closed loop systems only.
• Not suitable for open loop potable water or chilled water systems.
• Taco circulator pumps are for indoor use only – employer uniquement a l'interieur.
• Acceptable for use with water or maximum of 50% water/glycol solution.
FEATURES:
• Three easy settings to match system requirements - LOW, MEDIUM, HIGH.
• Replaces all single speed and 3-speed circulators in its class.
• ECM performance equivalent to the versatile Taco 0015 3-speed circulator.
• Multi-color LED display showing power on and error code diagnostics.
• Use with a Taco ZVC Zone Valve Control or SR Switching Relay for ON/OFF operation.
• Nut capture feature on flanges for easier fit up.
• Dual electrical knockouts and 6" stranded wire leads for easy wiring.
• Double insulated - no ground-wire required.
• Whisper quiet operation.
• BIO Barrier
protects the pump from system contaminants.

•
ure tart ™- automatic unblocking and air purging mode.
• Optional 2-way universal flange model for easy fit-up to any flange orientation. See Fig. 1.
• Integral Flow Check (IFC
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 fluids or certain chemical additives to systems using TACO equipment
voids the warranty. Consult factory for fluid 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 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.
ATTENTION : Des installations à des altitudes de plus de 1600 mètres doivent présenter une pression de remplissage
plus élevée de 20 psi au minimum afin d'éviter toute cavitation ou flashing 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 remplis-
sage. Un réservoir d'expansion d'une taille supérieure peut être nécessaire.

- Page 4 The circulator can be installed on the supply or return side of the boiler but for best system performance, it should always pump Location: away from the expansion tank. See piping diagrams in Figures No.1 and No. 2. CAUTION: Do not use flat rubber gaskets. Only use O-ring gaskets provided or leaks may result. Warranty will be void. Mounting position: Circulator must be mounted with the motor in the horizontal position.
- Page 5 Use flexible conduit only. Connect Line/Hot power to the black lead, Neutral to the white lead. See wiring diagram above. The 0015e3 is a double insulated circulator; no grounding wire is necessary. Replace terminal box cover. Insert cap plug provided to cover unused knockout hole.
- Page 6 0015 – (Low) Selection options are LOW, MEDIUM or HIGH. The 0015e3 circulator varies its speed in LOW and MEDIUM setting to maintain a constant pressure differential (∆p-c) in the system as heating load increases or decreases. On HIGH setting, the 0015e3 runs at full speed.
