Cattani Large Suction System
Cattani · Model Large Suction System
Flexible Design - Systems can be designed to suit each project’s particular needs. Built in back up for drainage system - The larger capacity Blok Jet suction systems include the added insurance of a dual drainage system that ensures that in the event of a failure of a drain system component, it can be quick and easily bypassed to ensure the suction system can continue to operate at full capacity. Remote access to control systems - Remotely access the unit’s control interface to monitor the operating status as well as any anomalies that may occur so that they can be acted upon as soon as possible. Amalgam Retention - The Cattani Hydrocyclone is a simple and effective amalgam retention unit that fully integrates with the SMART suction systems.
Key tips
- ·A no-signal/flatline alarm gets checked on the patient first, not the monitor - rule out a real clinical event before troubleshooting.
- ·Recalibrate NIBP against a reference manometer, not just a self-test pass.
- ·Reused patient cables (SpO2, ECG leads) are a common source of intermittent-fault complaints - swap the cable before the module.
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.
Low or no suction at the operatories
HighSymptoms: Weak or no aspiration at the dental units, low vacuum on the gauge.
Root cause: Worn suction motor / impeller (or ring / claw on liquid-ring units), an air leak in the distribution, or a blocked filter / amalgam separator.
Motor overheating / thermal trip
MediumSymptoms: Motor stops after a period, hot, restarts after cooling.
Root cause: Blocked cooling, a worn motor, or running dry (liquid-ring).
Amalgam separator / filter fault
MediumSymptoms: Separator-full alarm, reduced flow, drainage backing up.
Root cause: Full amalgam separator or a clogged central filter.
Excess noise / vibration
LowSymptoms: Loud operation, rattling.
Root cause: Worn bearings or loose mounts.
Will not start / no power
MediumSymptoms: Dead unit, contactor not pulling in.
Root cause: Power / fuse, the contactor / relay, or the demand-control / pressure switch.

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.
- ·Routine cable and lead-wire inspection for fraying/wear
- ·Battery conditioning cycle
- ·NIBP calibration check against a reference manometer
- ·ECG / SpO2 accuracy verification against a patient simulator
- ·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: Low or no suction
- Check and empty the amalgam separator and clean the central filter.
- Leak-test the distribution and the operatory hoses / valves.
- Confirm the motor runs at full speed and (liquid-ring) has its water supply.
- Measure the vacuum at the pump vs at the units.
- Rebuild or replace the pump if vacuum is weak with a sealed, clean system.
Symptom: Motor overheats / will not start
- Clear the cooling airflow and let it cool.
- Check the contactor / relay pulls in and the demand switch operates.
- Check the mains fuse.
- Confirm the water supply (liquid-ring).
- Rebuild or replace the motor if it keeps tripping.
