    If yes, decrease the air flow rate. Note: Please install the unit only on a hard floor. 6. If the BCU05 is controlled by a BVT3000/3300, connect the BVT plug to the connector called «BCU05» located on the BVT's front panel.

  • Page 14: Operating Notes

    BCU05 HR applications Operating notes 1. The BCU05 is be powered by the BVT3000/3300 and is designed for 24 hours a day operation as long as the probe is not exchanged. If the probe is to be ex- changed then switch off the unit and wait for 10 minutes before handling. The exchanger tip must be de-iced before connecting on probe.
