Hillrom Envision E700
Hillrom · Model Envision E700
Advanced Microclimate Technology Uses independent air cells to immerse and envelop for best in class pressure redistribution ShearRelief® System minimizes the effects of shear and friction during patient movement and bed articulation.
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 an air-cell / bladder 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.
CPR deflation slow
MediumSymptoms: Surface does not deflate quickly on the CPR control.
Root cause: CPR dump valve or hose fault.
Cover damage
MediumSymptoms: Tears or cracking in the top cover, fluid ingress.
Root cause: Wear or sharp objects.

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.
