ACCEPTABLE MOTOR MOUNTING POSITIONS AND EASY CASING ROTATION

1. Location: The circulator can be installed on the supply or return side of the water heater or heat source. See Figures 2 & 3 on previous pages for preferred locations.

2. Mounting Position: Circulator must be mounted with the motor in the horizontal position.
   See diagrams on page 4 for acceptable motor mounting orientations.

3. Flange model: Fasten circulator to system piping. The circulator flanges incorporate a nut grabber feature for easier installation

4. Union Model: Install the union tailpiece fitting set (sold separately) best suited for your system piping. (See union fitting options chart on the back cover). Install circulator by attaching pump casing to each union tailpiece fitting.
   Tighten union nut onto circulator threading (being careful not to overtighten) to complete the installation.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.
   To 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.
   Integral Flow Check (IFC®) option – An IFC® is included in the 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 diagram 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.

5. Filling the system: 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 startin 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 dou- ble-insulated appliance must be identical to the parts they replace.

6. 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 0018e is a double insulated circulator. No grounding wire is necessary.

7. Start the circulator: When purging the system, it is recommended to run the circulator at manual full speed operation long enough to remove remaining air from the bearing chamber. To do this, turn the dial clockwise to the ZONE CIRC – MAX position. This is especially important when installing the circulator in the off-season.
   Full Speed Operation: To run the pump at full speed during the fast fill, start-up and purge process, rotate dial clockwise to MAX speed setting. To return to the normal operating mode, turn dial to desired fixed speed, constant pressure, or proportional pressure setting.
   CAUTION: Never run the circulator dry or permanent damage may result.

8. Programming your 0018e circulator:

a. Taco 0018e ECM Circulator Mobile App – www.TacoComfort.com/0018e_UserManual

1. Search for Taco 0018e ECM Circulator mobile app within the App Store or Google Play on your mobile device.
2. Download the Taco 0018e ECM Circulator mobile app for free and install it on your mobile device.
3. Once complete, you are able to start using the app. Additional operating instructions can be found on the app itself.
   Turn the selector dial counter-clockwise to the Bluetooth® setting icon for 2-way (read/write) communication & control using the 0018e mobile app. This will enable wireless mode selection control, performance diagnosis & reporting. In this dial postion, SureStart® capability is disabled. When the selector dial is turned to any other position the 0018e mobile app can be used for 1-way (read only) communication, providing performance diagnosis & reporting.

Minimum software requirements:

• iOS version 10 (BLE compatible)
• Android version 4.4 (BLE compatible)

b. Manual Dial
Note: The 0018e is factory-programmed for maximum speed operating mode. A Blue LED will appear when first powered on.
If this is your desired operating mode, no programming changes are required.

The 0018e has 3 Operating Modes on the Selector Dial:

• Proportional Pressure ( TRV ) – Varies speed to maintain a proportional/variable pressure differential.
• Constant Pressure ( ZV ) – Varies speed to maintain a constant pressure differential.
• Fixed Speed ( ZONE CIRC ) – Infinitely adjustable settings (MIN-MAX).

To change operating mode and settings:
Modify the performance of the circulator as needed by rotating the dial using a flat screwdriver. When an operating mode is changed, a blue, orange or green LED will illuminate when the circulator is powered on. The LED will flash each time mode is changed.
See diagrams below to determine best mode of operation for the system.The selection of the right functioning curve depends on the characteristics of the heating system and the actual heat demand.

0018e Performance Curves

In TRV – Panel Radiator, Proportional pressure mode, the circulator maintains a proportional pressure differential (Δp-v) as heating load increases or decreases.
Flow will change in relationship to the change in pressure differential. Selection options are Medium or High. If unsure on proper setting, select Medium and adjust as needed.

In Zone Valve – Constant pressure mode, the circulator maintains a constant pressure differential (Δp-c) in the system as heating load increases or decreases.
Selection options are Medium or High.
See chart to left for equivalent 00 model at each setting.

Zone Circ – Fixed speed mode allows the installer to fine tune the circulator  flow rate to precisely match design load conditions. It is infinitely variable betweenMIN/MAX settings. See chart to left for equivalent 00 model at each variable speed setting.
CAUTION: Do not attempt to remove LED panel from circulator. Serious damage to circulator electronics may result.

Troubleshooting the error codes: Listed below are potential diagnostic error codes which will appear on the LED display in case of a malfunction.

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.
LED on| The flow is too high| Reduce the pump speed.
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.
One fuse in the installation is blown| Verify the fuses of the pump.
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| The circulator performance is too low| Increase the suction head. Increase speed or P setting.

Unlocking Procedure: A red light in the LED indicates the circulator rotor is blocked or sticking. Turn the selector to the position MAX, 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 flash of white LED light. If the blocking is not removed through the automatic release process after 100 attempts to restart, the circulator goes into standby and the LED remains solid red.
Perform the manual unblocking 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. Set the dial to the MAX position.
7. Connect power supply. Check for impeller rotation.
8. If the circulator still doesn’t run it will need to be replaced.
