Acceptable Motor Mounting Positions; Casing Rotation - Taco 00e Series Instruction Sheet

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.
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.
WARNING: Risk of electric shock. To reduce the risk of electric shock, be certain that it is connected only to a properly grounded, ground-
ing-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.
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-insu-
lated appliance, two systems of insulation are provided instead of grounding. No grounding means is provided on a double-insulated appli-
ance, 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.
Figure 5: Spin casing to change flow
direction.
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 in-
lbs torque.
CAUTION: Use flexible conduit only. Not for use with rigid conduit.
