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 Figs 2 & 3. 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.
WARNING: Use supply wires suitable for 90°C.
AVERTISSEMENT : Employer des fils d’alimentation adeqauts pour 90°C.

. 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 Figures No.1 and No. 2.
2. Mounting position:
Circulator must be mounted with the motor in the horizontal position. See Figs. 2 and 3 below for acceptable motor mounting ori-
entations.
3. 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.
Always install with motor in horizontal orienta-
tion. 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.
CAUTION: To reduce the possibility of noise transmission, be sure to add vibration dampeners to piping when
mounting circulator to wall or floor 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.
WARNING: Risk of electric shock. To reduce the risk of electric shock, be certain that it is connected only to a prop-
erly 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 rac-
cordée 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: Disconnect power when servicing.
AVERTISSEMENT : Couper l'alimentation lors de
l'entretien.
CAUTION: Use flexible conduit only. Not for use with rigid conduit.
ATTENTION : N'utiliser que du conduit flexible ; n’est pas fait pour
du conduit rigide.
CAUTION: Do not use flat rubber gaskets. Only use O-ring gaskets provided or leaks may result. Warranty will be void.
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 Figs 2 and 3 above.
CAUTION: When rotating pump body position, do not detach motor housing from the casing. Damage to the casing O-
ring and leakage may result.

4. Wiring the circulator: Disconnect AC power supply. Remove terminal box cover. Attach a wiring connector into knockout hole.
Use flexible conduit only. Connect Line/Hot power to the black lead, Neutral to the white lead. See wiring diagram above. The
0015e3 is a double insulated circulator; no grounding wire is necessary. Replace terminal box cover. Insert cap plug provided to
cover unused knockout hole.
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 diagram. Depress the spring tab with a small
screwdriver to insert wire into plug. Release tabs to complete connection.
5. Start the circulator: When purging the system, it is recommended to run the circulator at full speed long enough to remove all
remaining air from the bearing chamber. This is especially important when installing the circulator in the off-season. An orange LED
will illuminate when the 0015e3 is powered on.
Full Speed Operation:
To run the pump at full speed during the fast fill, start-up and purge process, rotate dial to HIGH setting. To return to the normal oper-
ating mode, turn dial to desired LOW, MEDIUM or HIGH 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.

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 ground-
ing. 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 double-insulated appliance must be identical to the parts they
replace.
AVERTISSEMENT : ENTRETIEN DES APPAREILS À DOUBLE ISOLATION. Un appareil à double isolation est marqué
avec un ou plusieurs des éléments suivants : les mots « DOUBLE INSULATION » ou « DOUBLE INSULATED » ou le
symbole de double isolation (carré dans un carré). Dans un appareil à double isolation, deux systèmes d'isolation
sont fournis plutôt que la mise à la terre ; aucun moyen de mise à la terre n’est fourni ni ne doit être ajouté. L'entretien
d'un appareil à double isolation exige de grandes précautions et une connaissance approfondie du système, et doit
être effectué par un technicien qualifié. Les pièces de rechange pour un appareil à double isolation doivent être iden-
tiques aux pièces remplacées.

lateur peuvent en résulter.
0015e3 Performance Curves
Selection options are LOW, MEDIUM or HIGH. The 0015e3 circulator varies its speed in LOW and MEDIUM setting to maintain
a constant pressure differential (∆p-c) in the system as heating load increases or decreases. On HIGH setting, the 0015e3 runs
at full speed. See chart above for operating curves and equivalent 00 model at each setting.

. Programming your 0015e3 circulator:
Note: The 0015e3 is factory-programmed for MEDIUM setting. If this is your desired operating mode, no programming changes
are required.
To change operating settings:
Modify the performance of the circulator as needed by rotating the dial using a flat screwdriver. An orange LED will illuminate when
the circulator is powered on. The LED will flash each time a setting is changed. See diagram below to determine best setting for the
system.The selection of the right operating curve depends on the characteristics of the heating system and the actual heat demand.
See cross-reference replacement chart on page 8.
The 0015e3 has 3 Operating Settings:
• LOW - 5 feet of head constant pressure, variable speed.
• MEDIUM - 10 feet of head constant pressure, variable speed.

7. Troubleshooting the error codes:
Listed below are potential diagnostic error codes which will appear on the LED display in case of a malfunction.
Unlocking Procedure:
A red 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 process 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.
