Arjo AtmosAir Totalcare
Arjo · Model AtmosAir Totalcare
Mattress replacement system. The AtmosAir® T-series Mattress Replacement System (MRS) has been specifically designed for the Hill-Rom® TotalCare™ bed frame and it is the only mattress for the TotalCare bed that utilizes the patented Self-Adjusting Technology™ (SAT).
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.
Mattress not firm / SAT system not supporting
HighSymptoms: Surface stays soft, patient bottoms out, will not firm up.
Root cause: Weight not opening the Self-Adjusting Technology (SAT) valves, internal tubing kinked or disconnected, or holes/damage in the SAT system.
Cover tear or cracking
HighSymptoms: Splits or cracking in the waterproof cover, staining, moisture inside.
Root cause: Wear or sharp objects - the mattress must not be used with a compromised cover.
Air cylinder leak
MediumSymptoms: One zone flattens, uneven support.
Root cause: Perforated or split air cylinder / bladder.
Pump green lamp does not light
HighSymptoms: No green lamp when the pump power switch is ON.
Root cause: Power cord unplugged, wall outlet on a wall switch, tripped breaker/blown fuse, or a damaged cord/switch.
Inflates only one side in rotation mode
MediumSymptoms: Lateral rotation only lifts one side.
Root cause: Red rotation hoses not connected to the red-tagged ports, a kink, a disconnect, or a hole in the rotation bladder.

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.
- In rotation mode, confirm the red hoses are on the red-tagged ports.
- If it still will not firm up, contact Arjo - do not attempt repairs beyond the IFU.
Symptom: Pump green lamp will not light
- Plug the power cord in and try a different wall outlet not controlled by a wall switch.
- Reset the circuit breaker or replace the fuse.
- Inspect the cord and power switch for damage.
- Contact Arjo if the cord and switch are good.
- Verify the pump runs and the mattress inflates.
