• Dual electrical knockouts and removable quick-connect terminal strip for easy wiring

• Whisper quiet operation

• BIO Barrier® protects the pump from system contaminants

• SureStart® automatic unblocking and air purging mode

• Rotatable control cover to allow any pump body orientation

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 using TACO 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 an 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” flange bolts are provided with the circulator to use on the discharge flange to prevent interference with the circulator casing. CAUTION: Do not use flat rubber gaskets. Only use O-ring gaskets provided or leaks may result. Warranty will be void. 2.

Wiring Diagram WIRING DIAGRAM LINE Removable Green Terminal Plug NEUTRAL L N G GROUND Terminal Screws 4. Wiring the circulator: Disconnect AC power supply. Remove terminal box cover. Attach a wiring connector into knockout hole. Use flexible 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.

. Programming your 0026e circulator: Modify the performance of the circulator as needed by rotating the dial using a flat screwdriver. When the circulator is powered on, the LED will illuminate and change color based on the operating mode selected. The LED will flash 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 flow / head requirements.

External connection for 0-10V DC / PWM signal WARNING: If there is a need to make external connection (PLC / Pump Controller) it is mandatory to perform the following operations. 1. Remove the 4 screws (1) to open the upper shell (2). 2. Remove the cap (3) for external signal wiring. 3. Disconnect the connector (4) from control board (5). 4. Insert the cable (6) into the cable gland M12x1.5 (7) and screw it to the cover. 5.

Analog or Digital Input In “0-10V” mode, the circulator accepts either a 0-10VDC voltage signal or a PWM signal. The selection of the type of signal is made automatically by the circulator. 0-10VDC Input The circulator operates at variable speed depending on the DC input voltage. At voltages between 2 V and 10 V, the circulator operates at a variable speed depending on the voltage: - Max. Speed voltage not exceeding or equal to 1V - Max.
PAGE 11
Analog Output 0-10V DC The circulator has an analog output signal feature to indicate the operating status and the presence of any errors. 0V Circulator off, not powered 2V Circulator powered in standby 4V Circulator on and running 6V Warning presence (overheating, air) 10V Alarm presence (Circulator blocked, under voltage, over temperature) Note: When input is unconnected 0026e circulator runs at full speed.
