FLOW CURVES

INSTALLATION

CAUTION
Voltage Hazard.
Can cause electrical shock or equipment damage.
Disconnect power before beginning installation.

• Read and understand the operating instructions before working on the pump.
• Only operate the pump if it is in perfect operating condition.
  Only use it as intended; staying aware of safety and risks, and adhering to the instructions in this manual.
• Install the pump in a frost-free, dry, well ventilated area.

1. Pump location considerations

• Locate the pump where there is sufficient room for installation and service. It is a good practice to install flanges and service valves (not included) on each side of the pump to allow service without draining the system. It is also good practice to install the circulator inlet as close to the expansion tank outlet as is practical.
• Do not place the pump at the lowest point in the piping system as this is where dirt and sediment collect. Do not place the pump at the highest point in the piping system, either, as this is where air accumulates.

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).

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.

WIRING

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.

PUMP OPERATION

WARNING
Pump Damage.
Do not start the pump until it has been filled with water and the system has been purged of air.
7. Starting the pump

• Do not start the pump until it has been filled with water and the system has been purged of air.
• Open the service valves on both sides of the pump to fill the system with water. Check for leaks.
• Turn the air vent screw in the middle of the housing counterclockwise until you hear air escape from the system.
  Placing a rag under the vent holes will help collect water.
• Run the pump with the air vent open. Water will drip from the air vent holes.
  Then, when all air is vented, close the air vent screw by screwing it clockwise back into place.

WARNING
Risk of scalding/burning
Depending on water temperature and pressure of the system, hot vapor or liquid can escape if the air vent screw is completely loosened.
Depending on water temperature and how long the pump has been running, the pump can become very hot.

8. Speed selection

• Turn the speed adjustment knob clockwise to increase the speed (see Fig. 9).
• See Figs. 2-4 on page 2 for the flow curves of each pump at the three different speeds.
• Select a speed to obtain proper flow needed for correct system operation.
