Taco 007e 2ECM High Efficiency Circulator- piping3

  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 and Figure 3.
    CAUTION: Do not use flat 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 diagrams below for acceptable motor mounting orientations.
    ACCEPTABLE MOTOR MOUNTING POSITIONS AND EZ CASING ROTATION
    Always install with motor in horizontal orientation. Position electrical junction box at 9 o’clock for best viewing orientation. Pump casing may be rotated to change flow direction. Locate the arrow on the casing body to determine flow direction.
    Taco 007e 2ECM High Efficiency Circulator- motor1To rotate the pump casing, remove the 4 motor screws. When rotating pump casing position, DO NOT detach motor housing from the casing. Damage to the casing O-ring and leakage may result. Simply spin casing to the proper flow direction desired as shown in Figure 4 and Figure 5. Reattach the 4 screws (1 ⁄8″ allens wrench required). Be sure motor is positioned correctly and is seated evenly to prevent leakage or damage to O-ring. Tighten motor screws evenly to 25-38 in-lbs torque.
    CAUTION: When rotating pump body position, do not detach motor housing from the casing. Damage to the casing O-ring and leakage may result.
    Integral Flow Check (IFC® ) option – An IFC® is included in carton. If required, press IFC into machined discharge port with plunger and o-ring facing in, until it snaps into place. Before installing, press IFC plunger to be sure it moves freely. See Figures: 4 & 5 above.
    CAUTION: To reduce the possibility of noise transmission, be sure to add vibration dampeners to piping when mounting circulator to wall or floor joists.

  3. Filling the system: Fill the system with tap water or a maximum of 50% propylene-glycol and water solution. The system must be filled 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 flush 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.
    WARNING: Use supply wires suitable for 90°C.
    WARNING: Disconnect power when servicing.
    CAUTION: Use flexible conduit only. Not for use with rigid conduit.
    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 qualified service personnel. Replacement parts for a doubleinsulated appliance must be identical to the parts they replace.

  4. Wiring the circulator: Disconnect the AC power supply. Remove the terminal box cover. Attach a wiring connector into the knockout hole. Use a flexible conduit only. Connect Line/Hot power to the black lead, neutral to the white lead. See wiring diagram to the right. Replace the terminal box cover. 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 the Wiring Diagram. Depress the spring tab with a small screwdriver to insert wire into the plug. Release tabs to complete connection. The 007e-2 is a double insulated circulator. No grounding wire is necessary.

  5. Start the circulator: When purging the system, it is recommended to run the circulator long enough to remove all remaining air from the bearing chamber. This is especially important when installing the circu lator in the off-season. An orange LED will illuminate when the 007e-2 is powered on.

  6. Green Mode: Responsive technology actively monitors system condi tions and automatically adjusts to optimize power consumption. In this mode the LED changes to green.
    Taco 007e 2ECM High Efficiency Circulator- wiring
diagram CAUTION: Never run the circulator dry or permanent damage may result.
    Taco 007e 2ECM High Efficiency Circulator- flow Green Mode: After 7 days of constant circulation, the 007e will self- adjust to Green Mode curve (low proportional pressure) for power optimization. See Green mode curve above. When the 007e-2 cycles OFF, the circulator resets to original Normal Mode curve.
    CAUTION: Do not attempt to remove LED panel from circulator. Serious damage to circulator electronics may result.

  7. Troubleshooting the error codes: Listed below are potential diagnostic error codes which will appear on the LED display in case of a malfunction.
    FAULTS| CONTROL PANEL| CAUSES| REMEDIES
    ---|---|---|---
    The circulator is noisy| | LED on| Suction pressure is insufficient – cavitation| Increase the system suction pressure within the permissible range.
    LED on| Presence of foreign bodies in the impeller| Disassemble the motor and clean the impeller.
    Loud noises of water circulation| Flashing white LED| Air in the system. Pump may be air-bound.| Vent the system. Repeat fill and purge steps.

Circulator is not running although the electrical power supply is switched on

| | LED off| Lack of power supply| Verify voltage value of the electric plant.
Verify the connection of the motor.
Circuit breaker might be tripped| Check circuit breaker at panel and reset if necessary
The circulator is defective| Replace the pump.
Overheating| Let the pump cool down for some minutes. Then try to re- start it. Verify that the water and ambient temperature are within the indicated temperature ranges.
LED red| The rotor is blocked| Disassemble the motor and clean the impeller. See unlocking procedure below.
| | Insufficient supply voltage| Verify that the power supply matches the data on the name plate.
Building does not get warm.| LED on| System may be air-bound| Vent system.
Repeat fill and purge steps.
8.  Unlocking Procedure: A red light in the LED indicates the circulator is locked or sticking. Disconnect and connect power supply to start the automatic release process. The circulator makes 100 attempts to restart (process lasts approximately 15 minutes).
Every restart is signalled by a short white flash of LED light. If the locking is not removed through the automatic release pr ocess after 100 attempts to restart the circulator, it goes into standby and the LED remains red. In this case follow the manual procedure described in the next steps: during any attempt, the red LED light keeps blinking; after that the circulator tries again to start. If the locking is not removed through the automatic release process (the warning light returns to be red), perform the manual steps described below.
1. Disconnect power supply – the warning light switches off
2. Close both isolating valves and allow cooling. If there are no shut-off devices, drain the system so that the fluid level is beneath that of the circulator
3. Loosen 4 motor bolts. Remove motor from casing. Carefully pull the rotor/impeller from the motor
4. Remove impurities and deposits from the impeller and casing
5. Reinsert the rotor/impeller into the motor
6. Connect power supply. Check for impeller rotation
7. If the circulator still doesn’t run it will need to be replaced
