ACCEPTABLE MOTOR MOUNTING POSITIONS CASING ROTATION
To rotate the casing, remove the 4 motor
screws and spin the casing to the desired flow
direction. Reattach the 4 screws (
1
⁄
8
" allens
wrench required). Be sure body gasket is seat-
ed evenly to prevent leakage. Tighten motor
screws to 34-42 in-lbs torque.
WARNING: Use supply wires suitable for 90°C, AVERTISSEMENT: Employer des fils d’alimentation adeqauts pour 90°C.
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 Figures No.1 and No. 2.
2
. Mounting position:
Circulator must be mounted with the motor in the horizontal position. See diagrams below for acceptable motor mounting orienta-
tions.
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.
Position electrical junction box at 9 o’clock position for best viewing orientation. 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. CAUTION: Use flexible conduit only. Not for use with rigid conduit.
CAUTION: Do not use flat rubber gaskets. Only use O-ring gaskets provided or leaks may result. Warranty will be void.
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.
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 diagram above.
