2. Pump orientation and flow direction
• The pump may be installed to discharge up or down, left or
right, but the motor shaft must be horizontal.
• An arrow on the motor housing indicates the direction of
flow (see Fig. 5).
Fig. 5. Install pump so that the motor shaft is horizontal.
3. Check Valve installation
If an integrated check valve is desired, one may be purchased
separately and installed as follows:
• Ensure that the discharge outlet of the circulator is free of
debris.
• Hold the check valve so that the end with the O-ring goes
into the pump first. Then press the check valve into the
compartment on the outlet side of the circulator. Press
firmly until it clicks into place (see Fig. 6).
NOTE: Pump must not be installed in upright
orientation.
4. Connect the pump
• Connect the pump to the piping system using included
flange gaskets.
• If necessary, use pipe hangers on either side of the pump
to minimize pipe-strain.
5. Changing conduit position (optional)
• It is good practice to install the pump so the conduit
connection is pointing downward (see Fig. 7).
• To change where the wiring comes into the pump, support
the motor assembly while removing the four (4) screws on
the motor assembly using a 5/32 in. (4mm) L-shaped hex
head wrench.
• Rotate the motor assembly to the desired position and
replace the screws.
• Tighten evenly, moving diagonally from one screw to the
next until you reach 44 in.-lbs.

• Check that the rotor shaft turns freely. If it does not turn
easily, disassemble and reassemble the unit again.

CAUTION
Voltage Hazard.
Can cause electrical shock or equipment damage.
Disconnect power before beginning installation.
Wiring must comply with applicable codes,
ordinances, and regulations and be performed by
a qualified electrician.
6. Electrical connection
• Loosen the two screws securing the wire box cover.
• Use 12 AWG to 14 AWG copper wires (follow local code for
any wiring restrictions),
• Connect the line (hot) wire to the L terminal and the neutral
wire to the N terminal (max 4.4 in.-lbs). Wire should be
rated to 194°F (90°C) or greater and be in accordance with
UL 778/13.10.
• Connect the ground wire to the ground screw inside the
box. (See Fig. 8).
• Reattach the box cover and ensure that the conduit or wire
cable is secure in the strain relief connector.
