- ·A cracked weld or loose frame joint is a safety-critical finding - pull the unit from service until it's repaired.
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.
Mattress not firm / SAT system not supporting

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: Mattress will not firm up
- Apply body weight to open the SAT valves; if newly delivered, allow up to 24 hours to acclimate.
- Open the cover and check the internal tubing for loose connectors and kinks.
- Inspect the SAT system for holes or damage.
- Confirm the intake / regulator valves are intact.
- If it still will not firm up, contact Arjo - do not attempt repairs beyond the IFU.
Symptom: Cover found torn or cracked
- Remove the mattress from service.
- Check for fluid ingress into the foam and cylinders.
- Fit a new cover of the correct specification.
- Inspect and disinfect the internal components per local protocol.
- Confirm the surface inflates and holds firmness before reissue.
