Hillrom 300 Wound Surface
Hillrom · Model 300 Wound Surface
Four alternating pressure cycle times Ten comfort control settings Low air loss for microclimate control Max inflate provides uniform firmness Vapor permeable and waterproof cover Audible and visual power failure alarms Sub mattress that remains inflated for eight hours enable continuity of care during electrical outages.
Key tips
- ·Casters and the wheel-lock brake take the most day-to-day wear - check both every PM, not just on complaint.
- ·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.
Surface will not inflate / not firm enough
HighSymptoms: Patient bottoms out, low-pressure alarm, surface stays soft.
Root cause: Blower/pump fault, a hose disconnect or kink, or a bladder / air-cell leak.
One zone / cell stays flat
MediumSymptoms: Localised loss of support.
Root cause: Perforated air cell or a failed cell connector.
Low-air-loss / microclimate weak
MediumSymptoms: Patient feels damp, little airflow through the coverlet.
Root cause: Clogged air filter or low blower output.
Cover damage
MediumSymptoms: Tears or cracking in the top cover, fluid ingress.
Root cause: Wear or sharp objects - do not use with a compromised cover.
CPR deflation slow
MediumSymptoms: Surface does not deflate quickly on the CPR control.
Root cause: CPR dump valve or hose 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.
- ·Caster / wheel and brake function check
- ·Frame, weld, and mounting-hardware inspection
- ·Upholstery / surface condition check
- ·Annual full PM
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: Surface will not firm up
- Confirm mains power and that the pump runs.
- Check the supply hose connections and inspect for kinks.
- Listen/feel for pump output.
- Replace the pump if it runs without output.
- Verify the surface holds pressure under a representative load.
Symptom: One zone flat
- Identify the flat cell and isolate it.
- Inflate it alone and check for a leak.
- Replace the perforated cell or connector.
- Reconnect and confirm even inflation.
- Check the cover for a tear.
