INTRODUCTION About This Manual ® This manual contains information on servicing the AC550 Flowtron Excel system which consists of the pump and a pair of garments. The manual is sectioned with tabbed dividers for ease of use and consists of the following sections. -
Page 10: General Description
General Description system is a specially designed non-invasive system for the Flowtron Excel prevention of deep vein thrombosis (DVT). The application of external pneumatic compression has two effects : Augments venous blood flow velocity, thereby reducing stasis, and Enhances fibrinolytic activity to reduce the risk of early clot formation. system is comprised of a pressure regulated pump unit and Flowtron Excel a pair of calf or thigh length, single patient use garments. -
Page 11: Technical Description
Technical Description The pump is an electromechanical unit designed to supply compressed air to the garments while controlling the inflation time and pressure. In addition, an electronic module monitors pressure and fault conditions only. It is independent of the control system, and functions independent of thepump pressure. -

Page 17: Operational Maintenance
OPERATIONAL MAINTENANCE Routine Checks These procedures should be carried out each time the system is used. Inspect the pump unit for external damage to case, controls, and connections. Inspect power cord for damage or twisting, and replace if necessary. Check that the control knob is set to the recommended setting of 40 mmHg. - Page 18 247901 Issue 1 March 1998...

Page 19: Troubleshooting
TROUBLESHOOTING ® pump unit has both an audible and a visual alarm. If a Flowtron Excel problem occurs, the system will sense the fault and briefly flash a message on the display. It will not alarm immediately in order to screen out false alarms due to normal patient movement. -
Page 20: Service Mode Checks
Service Mode Checks Service mode gives additional information on the type of alarm fault. To access the service mode, hold the Single Leg button down for approximately 13 seconds. The unit will then ‘beep’ and the red LED on the top panel will be constantly displayed. - Page 21 3.0.0.1 Fault Codes and Counter Measures 247901 Issue 1 March 1998...

Page 23: Preventive Maintenance
PREVENTIVE MAINTENANCE Preventive maintenance should be carried out every 12 months. WARNING Before dismantling the pump unit, ensure unit has been isolated from the power supply by removing the cord plug from the wall outlet. CAUTION : Static Sensitive Devices This pump should only be opened by personnel trained in ESD methods and with appropriate equipment and anti-static protection. -

Page 25: Pressure Control Calibration
Inaccuracy of the pressure display - see Section 4.4 Pressure Display Calibration. Use the following procedure to check the pump: Hold the Single Leg button down until display changes to Service Mode resolution (see Section 3.2). Set control knob to 12 o’clock position. Ensure garments are connected to both outputs. -
Page 26: Pressure Display Calibration
Pressure Display Calibration ® utilizes a precise and accurate pressure management Flowtron Excel system which is not expected to require re-calibration until after several years of continuous use. The measurement system automatically handles any adverse effects due to drift or temperature change and should not require any user intervention. - Page 27 WARNING : DURING CALIBRATION AC POWER VOLTAGES ARE PRESENT With the pump switched Off and disconnected from the power supply, remove the top cover as detailed in Section 4.1.1 Carefully disconnect the two tubes attached to the pressure transducer and attach a suitable piece of spare tubing to one of the ports of the transducer, leaving both the other end of the tube and the other transducer port disconnected.
