Page 4: Notes For The User
• modifications, repairs or adjustments are or were carried out solely by Biegler or authorised personnel • only original Biegler spare parts are used for repairs (also applies to power supply cable). If the buzzer or red warning light comes on, remove the infusion or transfusion tube from the heating element and disconnect the connection tube to the patient immediately . -

• wait for the temperature to stabilize • turn the spindle-trimmer P5 slowly clockwise, until the alarm-buzzer gets active • now the BW 585 slowly cools down Now check the safety cut-off again ! 45°C ( thermal time delay ) •... - Page 6 3 . S a f e t y C u t - o f f 37°C ( low temperature alarm ) • The low temperature alarm could only be activated 60 seconds after switch on the warmer. If the temperature of the heat-exchanger drops below 36,5°C, the low temperature alarm will be activeted , the first LED of the temperature control will flash and an intermittent audio alarm will sound.

1) Preparing to set the temperature • Start the test program on the computer • Plug the PC – BW 585 connecting cable into the test socket with the flat side facing outwards • Connect the blood warmer to the power supply •... - Page 8 Service interface The BW 585 is equipped with a service interface. The serial interface supplies a range of data which can prove very useful when calibrating and troubleshooting. The BW 585 can be connected direct to a PC or terminal with a suitable cable (see below) and the data displayed using a standard terminal program (Hyper Terminal).

Inspection Instructions BW 585 Blood Warmer November, 2007 BW Manufacture, Assembly, Test Documentation Page 13... - Page 14 The person carrying out inspection of the equipment must be familiar with all the steps described in these instructions. The instructions are intended as a reference for completing the BW 585 inspection records. BIEGLER will notify customers of any amendments.
- Page 15 1. CONTINUOUS TEST 1.1 General • Start-up at 38,5 °C • After approx. 15 min. measure the temperature at the heat exchanger • After 24 h measure the temperature again During this test the initial and final values must be within the tolerance range and the measurements must be taken under the same ambient conditions.
- Page 16 2.READY FOR USE 2.1 General •Start-up at 41 °C •Time how long it takes for the operating temperature of 40,5°C to be reached The initial temperature should be the same as the ambient temperature. The time taken must be less than 60 sec. For arrangement of heat exchanger and measuring instrument, see Fig.1.1.1 3.OPERATING TEMPERATURE CHECK 3.1 General...
- Page 17 5.1 General Apply test voltage of 1.5 kV ~ to the heat exchanger for 1 min. The test must be performed on the BW 585 after operating temperature has been reached and with the equipment still in operation (see Fig.5.1.1) There must not be any flashovers or breakdowns during the test (slight corona discharge can be disregarded).
