Key tips
- ·Never skip temperature-accuracy verification to save time - it's the one check that directly prevents burns.
- ·Hose/blanket connector wear is the most common real fault and the easiest to miss on a quick visual check.
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.
Will not reach or hold set patient / water temperature
HighSymptoms: Water temperature drifts from setpoint, patient temperature not tracking, over/under-temp alarm.
Root cause: Heater / thermoelectric or refrigeration fault, a temperature-probe fault, or a circulation-pump / flow fault.
Circulation-pump / flow fault
MediumSymptoms: Low-flow alarm, blanket not filling, pump noisy.
Root cause: Worn pump, an air-locked circuit, or a kinked / disconnected hose.
Patient-probe fault
MediumSymptoms: Patient temperature implausible or open-probe alarm, auto-control will not regulate.
Root cause: Damaged patient temperature probe or its connector.
Leak / reservoir fault
MediumSymptoms: Low-water alarm, water on the floor, air in the lines.
Root cause: Reservoir low, a hose / fitting leak, or a blanket leak.
Refrigeration fault (cooling units)
MediumSymptoms: Cannot cool water, compressor not running.
Root cause: Compressor, condenser fan, or a sealed-system 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.
- ·Hose / blanket connector inspection
- ·Temperature-accuracy verification
- ·Annual electrical safety test
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: Will not hold set temperature
- Confirm the reservoir is filled and the blanket circuit is primed (no air).
- Verify the water temperature against an independent thermometer.
- Check the patient probe against a reference and swap it.
- Confirm the circulation pump delivers flow.
- Replace the probe, pump or heater / refrigeration components as isolated.
Symptom: Low-flow or leak alarm
- Check the hoses for kinks and confirm the quick-connectors are seated.
- Top up the reservoir and bleed air from the circuit.
- Inspect the blanket and hoses for leaks.
- Replace a leaking hose / blanket.
- Confirm the flow alarm clears and temperature control is stable.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
Terumo CVS has been unable to validate a cleaning protocol to satisfy current regulatory concerns and expectations. As a result, an updated cleaning protocol will not be developed by Terumo CVS and it has been determined that the best course of action is for users to discontinue use of and dispose of HX2, TCM I and TCM II devices.
- RECALL
Update to cooler-heater cleaning instructions.
- RECALL
Terumo Cardiovascular Systems (Terumo CVS) is conducting a voluntary recall of its heater-cooler devices due to the distributor no longer selling the Interchlor sanitizer (Product Code 205) referenced in its heater-cooler cleaning instructions.
- RECALL
Malfunctioning mixing valve and loss of cooling and/or heating capability. System goes to standby mode and shows error messages EOd (invalid mix valve measured range of motion) or EOE (valve unable to move or complete a motion). Mixing valves need to be replaced at regular intervals.
- RECALL
Based on a retrospective review of quality data, AC Control boards used in the manufacture of the HX2 Temperature Management System were identified as being manufactured using the incorrect flux material. Use of the incorrect flux may contribute to premature board failure. A search of TCVS complaints revealed 3 complaints received related to the HX2 failure. Each failure occurred during set up
- RECALL
The HX2 Temperature Management System mixing valve may fail resulting in an unusable water channel and then the machine would go into standby mode.
