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.

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

CAUTION: Do not use at rubber gaskets. Only use O-ring gaskets provided or leaks may result. Warranty will be void.

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 ow direction. Locate the arrow on the
casing body to determine ow direction.

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 oor joists.

ATTENTION: Pour réduire la possibilité de transmission de bruit, veillez à ajouter des amortisseurs de vibration à la tuyauterie lors du
montage du circulateur sur des chevêtres de mur ou de plancher.

3. Filling the system: Fill the system with tap water or a maximum of 50% propylene-glycol and water solution. The

system must be lled 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 ush 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.

AVERTISSEMENT: Risque de choc électrique. Pour réduire le risque de choc électrique, veillez à ce qu’elle soit raccordée uniquement à un
réceptacle de type mise à la terre proprement mis à la terre. Respectez tous les codes de plomberie et électriques locaux.

WARNING: Use supply wires suitable for 90°C. AVERTISSEMENT: Employer des ls d’alimentation adeqauts pour 90°C.

WARNING: Disconnect power when servicing.

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 ow 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: Use exible 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 qualied service personnel. Replacement parts for a double-insulated appliance must be identical to
the parts they replace.

Use exible con-duit 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 eld 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. Depress the spring tab with a small
screwdriver to insert wire into plug. Release tabs to complete connection. The 0018e is a double insulated circulator, no grounding wire

is necessary. Replace terminal box cover.

5. 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 ll, start-up and purge process, rotate dial clockwise to MAX speed setting. To return to the
normal operating mode, turn dial to desired xed speed, constant pressure, or proportional pressure setting.

CAUTION: Never run the circulator dry or permanent damage may result.
ATTENTION: Ne laissez jamais le circulateur tourner à sec, des dommages permanents peuvent en résulter.

b. Manual Dial

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

The 0018eTM 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 ) - Innitely adjustable settings (MIN-MAX).

To change operating mode and settings:

Modify the performance of the circulator as needed by rotating the dial using a at screwdriver. When an operating mode is
changed, a blue, orange or green LED will illuminate when the circulator is powered on. The LED will ash 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.

Unblocking 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 ash 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 uid 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.
