Infinitely Variable Speed, ECM High-Efficiency Circulator

DESCRIPTION:

he 00e

™

eries VR1816 circulator is an infinitely variable speed wet rotor circulator with

an ECM, permanent magnet motor. Operating modes include infinitely adjustable fixed

peed or self-adjusting proportional or constant pressure variable speed. Its high effi-

ciency motor reduces power consumption by up to 85% compared to equivalent AC per-

manent 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.

• 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:

• 3 operating modes:

- Fixed speed ( ) - infinitely adjustable MIN/MAX settings

- Constant pressure ( ), variable speed - 3 constant pressure differential curves (5, 10, or 15 maximum feet of head)

- Proportional pressure ( ), variable speed - 3 variable pressure differential curves (High, Med, or Low)

• Multi-color LED display showing operating mode 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.

• SureS tart automatic unblocking and air purging mode.

• Optional 2-way flange model for easy fit-up to any flange orientation.

• Integral Flow Check (IFC

) included - Field installed.

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 flash-

ing. 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 remplissage. Un réservoir d'expansion d'une taille supérieure peut être

nécessaire.

T 4. Wiring the circulator: Disconnect AC power supply. Remove terminal box cover. Attach a wiring connector into knockout hole. Use flexible conduit only. Connect Line/Hot power to the black lead, Neutral to the white lead. See wiring diagram. Note: If pigtail leads provided are not used, be sure to trim field wire to a strip length of .25" (+/- .025") to prevent exposed wire causing a short at the terminal plug. Connect line and neutral to green terminal plug as shown in diagram.
