General safety information

  1. Installation, electrical connection and commissioning of the pump may be carried out only by qualified contractors and all general and local safety measures must be observed.
  2. Operating instructions and associated documents must be complete, legible and accessible at all times.
  3. Before carrying out work on the pump, read and ensure that you understand the operating instructions.
  4. This circulation pump is suitable only for water of potable quality.
  5. The pump should be operated only if it is in technically perfect condition. It must be used only in accordance with intended use, with an awareness of safety and risks, and in accordance with these instructions.
  6. Before any installation and maintenance work, disconnect the motor from the power supply and secure against reconnection.
  7. The use, cleaning and maintenance of this device by children aged 8 years or older, persons of restricted physical, sensory or mental capabilities, or persons with limited experience or knowledge is permitted only if they are supervised or instructed in the safe use of the device and understand the associated risks. Children must not be allowed to play with the device.

The BWO 155 BlueOne pumps are DHW circulation pumps driven by a high efficiency, electronically commuted DC motor. They are built on the original VORTEX spherical motor principle and contain a permanent magnet spherical motor.

The speed of the pump is infinitely adjustable.

The pump has LEDs and pushbuttons to display and set the operating state.


Operation

  1. The pump runs according to the set running times.
  2. The time and running times are displayed by LEDs (time: red; running times: green; smallest time segment = 30 min).
  3. In the event of a power failure, the time stops (no power reserve). The selected running times are retained. Once the power supply is restored, the pump runs in the operating state that was last set. The time may have to be set again.
  4. KT version: The pump is equipped with a thermostat. At a water temperature above 55 °C, the pump switches OFF; it switches back ON when the water has cooled down to below 45 °C. The thermostat function is only active during the selected running times (LEDs with steady green light).

CAUTION! Ingress of water will cause physical damage!

  • Ensure that the cable entry and cable face downwards after installation.
  • Select a suitable installation site and permissible installation position.

  • Avoid exposing pumps with thermostatic functions, such as the ERT or SL, to heat:
    – Maintain a clearance of at least 50 cm from the DHW heater.
    – If the return line opens vertically into the cylinder, install the pump well away from the cylinder entry.

  • Fit shut-off valves and a non-return valve (Δpmax = 0.2 kPa or 20 mbar).

  • The integrated shut-off valve in the V-pump housing and the Vortex screw-in valves are only provided to enable a brief shut-off while the motor is replaced.
  • Integral valves on V pumps

  • Optional screw-in valves on R pumps (W-valves)

  • Integral screw-in valves on BWO 155 RW pump
  • Optional screw-in valves on R pumps (RV 153, KV 150)

  • When installing the pump, ensure that it is not under strain.

  • Observe correct direction of flow.



DANGER! Pressurised system!

  • Before working on the motor or pump connections, close the shut-off valves.


  • Rotate the pump control panel if necessary so that it is visible (cable exit underneath). To do so, slightly loosen the union nut …

  • … turn the motor …

  • … and retighten the union nut (max. 20 Nm).


  1. Fully separating the motor from the pump housing is only necessary for maintenance purposes (see chapters ‘Flushing and venting’ and ‘Maintenance’).
  2. The pump has dry-running protection. If it runs largely in air, the PCB will repeatedly stop it to protect the rotor bearings. In a fully vented circulation circuit, the pump will run uninterrupted.

CAUTION! Dry-running will damage the bearings!

  • Flush the pipework thoroughly with water and vent it.


DANGER! Pressurised system!

  • Before working on the motor or pump connections, close the shut-off valves.


WARNING! Risk of scalding due to hot water!

  • Avoid direct contact with escaping hot water.
  • The pump housing can similarly reach a high temperature due to the hot medium being pumped.


  1. If no venting valve (fill & drain valve) is present, the system must be vented through the pump housing.
  • To vent, first close the shut-off valves.

  • Unscrew the motor from the pump housing …

  • … and screw the venting flange (VORTEX EF 150) onto the motor (max. 20 Nm).

  • Open the shut-off valve upstream of the pump again and allow water to escape through the venting flange until the pipework is free of air.

  • Close the shut-off valve upstream of the pump …

  • … unscrew the venting flange from the pump …

  • … and reattach the motor to the pump housing.

  • Retighten the union nut (max. 20 Nm).

  • Slowly open the shut-off valves again.

  1. The pump is driven by a DC motor.
  2. The transformer for AC operation is built into the connection cap.
  3. As it is in protection class 2, no earth conductor is required.


DANGER! Electric shock can kill!

  • Work on the electrics must be carried out only by authorised contractors. 
  • Disconnect the pump from the power supply and secure against reconnection.
  • Check that no voltage is present.


WARNING! Risk of fire due to electrical ignition!

  • Ensure that the pump is connected only to the power supply specified on the type plate.



  • A permanent connection to the power supply is possible; alternatively use a mains plug with IP 44 rating (provide all-pole disconnection).
  • Round cable diameter 5–8 mm
  • Wire cross-section 0.75–1.5 mm2
  • Strip 8.5–10 mm of insulator from the ends of the wires.
  • Twist the wire ends; do not use wire-end sleeves or tinned ends.
  • Undo the module cap with a TX10 screwdriver.

  • Undo the cap nut and insert the cable.

  • Push yellow lever forward and insert the wire into the red cable terminal. Release the lever again.

  • Allow a suitable length of cable and retighten the cap nut.

  • Adjust speed by turning the rotating yellow knob:
    1 = min. speed (2000 rpm)
    2 = medium speed (2500 rpm = factory setting)
    3 = max. speed (3000 rpm), or use any intermediate position.

  • Screw the module cap on firmly.

  • To vent any remaining air, switch the pump on and off several times …

  • … and open the DHW tap several times …

  • … until the pump runs quietly.
