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 & Figure 3.
NOTE:Two shorter 1-1/4”x 7/16”ange bolts are provided with the circulator to
use on the discharge ange to prevent interference with the circulator casing.
CAUTION: Do not use at 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 Figure 4 & Figure 5
below for acceptable and unacceptable motor mounting orientations. See Figure 6 for Rotating Control Cover.
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 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.
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.
AVERTISSEMENT : Couper l’alimentation lors de l’entretien.
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 sym-
bol (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.
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 eectué par un technicien qualié. Les pièces de rechange pour un appareil à double isolation doivent être
identiques aux pièces remplacées.
4. Wiring the circulator: Disconnect AC power supply. Remove terminal box cover. Attach a wiring connector
into knockout hole. Use exible conduit only. The green terminal plug may be removed to simplify wiring, then
snapped back in place. Connect Line/Hot power to the L terminal, Neutral to the N terminal and Ground to the
G terminal. See wiring diagram above. The 0034e is a double insulated circulator; grounding wire is not necessary but
recommended for safety. Replace terminal box cover. Insert rubber cap plug provided to cover unused knockout hole.
4a. Wiring the circulator for 0-10V DC Operation: (See Page 9)
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 o-season. Turn the dial to the HIGH setting for maximum xed speed. A blue LED will
illuminate when the 0034e is powered on.
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 ll, start-up and purge process, rotate dial to HIGH setting. The LED will
change to blue. To return to the normal operating mode, turn dial to desired activeADAPT, LOW, MEDIUM, HIGH or
0-10V setting.

6. Programming your 0034e circulator: Modify the performance of the circulator as needed by rotating the dial
using a at screwdriver. When the circulator is powered on, the LED will illuminate and change color based on the
operating mode selected. The LED will ash each time a setting is changed. See diagram below to set pump for
desired operating mode. The selection of the right operating curve depends on the characteristics of the system
and the actual ow / head requirements. See Pump Curves on pages 7, 8 & 10 to determine the best operating
mode for the system. See cross-reference replacement chart on back page.

Analog Input
In the “external input” mode, the circulator accepts either a 0-10VDC voltage signal or a PWM signal. The selection
of the signal type is automatically made by the circulator without operator intervention.
Input 0-10V DC
The circulator operates at variable speed depending on the DC input voltage.
At voltages below 1.5 V, the circulator is in “standby” mode. LED will be ashing yellow in “standby” mode.
At voltages between 2 V and 10 V, the circulator operates at a variable speed depending on the voltage:
- 0% for a voltage not exceeding or equal to 2 V
- 50% at 7 V
- 100% for voltages greater than or equal to 10 V
Between 1.5 V and 2 V the circulator can be in “standby” or at minimum speed depending on the previous state
(hysteresis). See diagram below.
IMPORTANT: If the input remains disconnected, the circulator goes into Standby Mode.
