Infinitely Variable Speed, ECM High-Efficiency Circulator

DESCRIPTION:

The Viridian VR1816 circulator is an infinitely variable speed wet rotor circulator

with an ECM, permanent magnet motor. Operating modes include infinitely

adjustable fixed speed or self-adjusting proportional or constant pressure variable

speed. Its high efficiency motor reduces power consumption by up to 85% com-

pared 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.

• 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 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.

• Integral Flow Check (IFC) is included in carton. Simply press into discharge flange if required.

• Nut capture feature on flanges for easier fit up.

• Whisper quiet operation.

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.
