ACCEPTABLE MOTOR MOUNTING POSITIONS AND EZ CASING ROTATION
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
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.
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 Figure 2 and Figure 3.
2. Mounting position: Circulator must be mounted with the motor in the horizontal position. See Figure 4 and Figure 5 below for
acceptable motor mounting orientations.
3. 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.
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 Figure 4 and Figure 5 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.
