DESCRIPTION 2.1 GENERAL DESCRIPTION The BIEGLER BW 685 / BW 685 S is a warmer for infusions or transfusions and operates on the basis of a continuous flow warmer, where the heat from the heat exchanger is transferred via the extension tubing to the liquid flowing within it.
BW 685 / BW 685 S / TubeFlow 2.3 CONSUMABLES Various consumables are available according to requirements. For use with BW 685 or BW 685 S without the tube warmer: Extension set 350 cm Order no. 35000 Extension set 460 cm Order no.
10 Fluid exit point 11 Alarm LED Flow direction Fix the BIEGLER BW 685 / BW 685 S firmly to the infusion stand using the clamps at the back (Fig. 1/8). Only use infusion stands, tripods or equipment rails that are sufficiently stable.

The tube warmer Biegler TubeFlow must be inserted with light pressure as indicated in diagram 3.2 into the intended fixture (Diag. 3/4) on the BW 685 S. Remove the dust cap from the BW 685 S and attach the connector of the TubeFlow to the socket on the BW 685 S.
3.2 ALARMS The BW 685 / BW 685 S can trigger two types of temperature alarm: The low temperature alarm is activated when the temperature of the heat exchanger drops below 36.5 °C. The audible low temperature alarm is not active during the first 60 seconds after switch-on.
TubeFlow MAINTENANCE The BW 685 / BW 685 S was largely designed as a maintenance-free device. For long-term maintenance of quality and functional safety, we would like to ask you to observe the following points:...
The periodic technical safety inspections (according to the local standards in force - e.g. in Austria, ÖVE/ÖNORM E 8751-1) on the BW 685 / BW 685 S and the optional tube warmer TubeFlow must be carried out at least every 12 months, by persons authorized to carry out such inspections based on their training, knowledge and practical experience.

BW 685 / BW 685 S / TubeFlow CHECKING THE WARM-UP PERIOD (BW685/S) This is the time taken by the BW 685 / BW 685 S to heat up to 38.5 °C from room temperature. If this time is much more than one minute, there is a malfunction.
Page 17
BW 685 / BW 685 S / TubeFlow VISUAL CHECK OF GENERAL CONDITION (BW685/S) The device should be checked for mechanical damage (general condition) and for the completeness of the stickers, particularly the device label on the reverse. If there is mechanical damage to the device which could cause risk of injury or impair its functionality, this constitutes a malfunction.

BW 685 / BW 685 S / TubeFlow An independent temperature sensor is installed in the TubeFlow warmer. The electronic system continuously monitors the sensor. The heating is permanently switched off if a certain predefined temperature is exceeded. In order to examine this overtemperature activation, a calibrated circulation thermostat which can be set to temperatures between 39 °C and 45 °C is...
