FLOWTRON ACS900
Arjohuntleigh AB · Model 526000-01
DVT Prevention Compression Pump - ACS900 PUMP US STD TUBE SET.
Intended use: A system used for the noninvasive treatment and prevention of venous disorders and sequelae such as oedema, deep vein thrombosis (DVT) and pulmonary embolism (PE). It functions by intermittently applying pressure to a patient's arms or legs to promote venous blood flow at timed intervals. This is achieved through the cyclical inflation and deflation of a single-chambered stocking, sleeve, or suit applied to the extremities. The system typically consists of a compression pump, control and timing mechanism, tubing, and pneumatic stocking(s) or suit.
Key tips
- ·When no category-specific guidance fits, default to the manufacturer's own service manual and the general troubleshooting method in the Engineer's Guide.
- ·Run an incoming and annual electrical safety test regardless of how niche the device is.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Garment does not inflate / low pressure
HighSymptoms: Sleeve does not fill, low-pressure or garment-fault alarm, no compression cycle.
Root cause: Garment or tubing disconnected, kinked or leaking, wrong garment selected, or a pump / valve fault.
Pump runs but no compression cycling
MediumSymptoms: Pump audible but the garment does not alternate or hold.
Root cause: Rotary / solenoid valve or the manifold in the pump.
Pressure inaccurate / out of range
MediumSymptoms: Delivered pressure does not match the set / rated value.
Root cause: Pressure transducer drift or a control-board fault.
Will not power on / alarm will not clear
MediumSymptoms: Dead unit, or a persistent alarm.
Root cause: Power supply, fuse, or a control fault.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Follow the manufacturer's PM schedule
- ·Perform incoming and annual electrical safety testing per facility biomedical program
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Garment will not inflate
- Confirm the garment type matches the pump setting.
- Check the tubing and connectors are seated and not kinked; leak-test the garment.
- Listen for the pump and valve cycling.
- Fit a known-good garment and tubing set.
- Replace the pump or valve if it will not build / hold pressure.
Symptom: Pressure inaccurate
- Tee a calibrated manometer to the garment line.
- Compare delivered pressure to the rated value through a cycle.
- Recalibrate per the service manual or replace the transducer.
- Re-verify.
- Record the check.
