HAMILTON-C1

1. Make sure the patient is safe — swap in a backup unit if you need to.
2. Reproduce the complaint yourself and write down exactly what you see (screen, alarm, code).
3. Check power, battery, cables, accessories, and settings before ordering parts.
4. Then open the service manual above and follow its troubleshooting section.

Technical fault (Safety ventilation / Ambient state) source ↗

• Provide alternative respiratory support
• Note the fault code, remove from use, have it serviced

Disconnection on patient side source ↗

• Check circuit between patient and flow sensor, ET tube leaks
• Check expiratory valve set is intact and installed properly

Check flow sensor / Check flow sensor tubing source ↗

• Check sensor and tubing; remove water
• Recalibrate flow sensor; replace if needed
• 3 consecutive breaths → Sensor Failure mode

Loss of PEEP source ↗

• Check circuit and airway for leaks/disconnection
• Confirm settings and alarms

Battery low / Battery power loss / communication error source ↗

• Connect to AC, install charged battery
• Battery error/wrong battery: have battery replaced

Blower fault / Fan failure source ↗

• Blower fault: provide alternative ventilation, service
• 'Blower service required' = end of life

CO2 sensor alarms source ↗

• Check adapter/sampling line for water or secretions
• Zero-calibrate away from CO2 sources
• Check cable/module connections; replace sensor

Any technical fault source ↗

• Ventilate patient by other means first, note code, send for service

Disconnection/leak/loss of PEEP source ↗

• Check circuit, ET tube and expiratory valve

Flow sensor alarms source ↗

• Remove water, recalibrate, replace sensor
