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 page 2 for preferred locations.
2. Mounting position: Circulator must be mounted with the motor in the horizontal position. See diagrams below for acceptable motor
mounting orientations.
3.
Install the union tailpiece fitting set (sold seperately) best suited for your system piping. (See Union Fitting Options chart on page 7).
CAUTION: Install fittings to system piping before connecting the circulator to avoid damaging the pump’s composite casing.
4.
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.
CAUTION: Only use union gaskets provided with union fitting sets or leaks may result. Warranty will be void.
ACCEPTABLE MOTOR MOUNTING POSITIONS
Figure 4: Always install with motor in
horizontal orientation.
Figure 5: Spin casing to change flow
direction.
Figure 6: Do not detach motor frame from pump
casing. Simply spin casing to the
proper flow direction.
CASING ROTATION
X
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.
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.
5. 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. See page 2 for recommended air purging steps.
To rotate the pump casing, remove the 4 motor screws using a 5/32" (4 mm) allens wrench.
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. Be sure motor is positioned correctly and
is seated evenly to prevent leakage or damage to O-ring. Tighten motor screws evenly to 25-33 inlbs torque.
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 fils d’alimentation adeqauts pour 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 double-insulated appliance must be identical to the
parts they replace.

No ground wire is required.
7. Start the circulator: When purging the system, it is recommended to run the circulator at full speed long enough to remove
remaining air from the bearing chamber. This is especially important when installing the circulator in the off-season.
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.
Full Speed Operation:
To run the pump at full speed during the fast fill, start-up and purge process, rotate dial to MAX speed setting. To return to
the normal operating mode, turn dial to desired speed setting.
8. Programming your 006e3 circulator:
Note: The 006e3 is factory-programmed for Medium speed operating mode. If this is your desired operating mode, no pro-
gramming changes are required. If flow velocity noise develops, turn dial counter-clockwise to reduce pump speed until noise
disappears.
006e3 Operating Modes
• 3 Fixed Speed Settings ( ) - Low, Medium, High
• Pre-marked 003/006 equivalent settings
• Min-Max infinitely variable fixed speed settings for fine tuning
To change operating speed settings:
Modify the performance of the circulator as needed by rotating the programming dial using a flat screwdriver. A blue LED will illuminate when the circulator is powered on. The LED will flash each time mode is changed. The selection of the right performance
curve depends on the characteristics of the system and the actual flow and head requirements. See 006e3 Performance Curves
and Setting Selection Guide on page 7 to determine best speed setting for the system.
CAUTION: Do not attempt to remove LED panel from circulator. Serious damage to circulator electronics may result.
ATTENTION: N'essayez pas de retirer le panneau de LED du circulateur. Des dommages sérieux à l'électronique du circulateur peuvent
en résulter.

of a malfunction.
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 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.
