Ossur Americas Cold Rush
Ossur Americas · Model Cold Rush
Cold Therapy System Go with the flow. By incorporating the same durable motor used in much larger mobile air conditioners and refrigerators, Cold Rush provides consistent cooling and excellent compression, even to high elevations. Quiet as a whisper. Cold Rush uses a brushless motor to produce a whisper-quiet (30 decibel) unit that allows patients to get the rest they need to properly rehabilitate from their injuries. Stay cooler, longer! The highest ice-to-water ratio in the industry and a design that produces less heat transfer from the motor to the water combine to ensure cold therapy pain relief for up to 6 continuous hours. No igloos! Far more than just a modified beverage cooler, Cold Rush was designed holistically, with unique features like a locking lid to help prevent spills and insulated walls for improved cooling.

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: No flow / pad not cold
- Ensure the reservoir has both ice and water; allow ~10 minutes to stabilise.
- Confirm power and that plugs are fully engaged, and the hose is not kinked.
- Disconnect and reconnect the pad and release trapped air at the connector.
- Place the unit on a raised surface and loosen wraps.
- Clean the inlet filter and reassemble.
Symptom: Pad will not fill
- Lay the pad flat and below the unit and let it fill.
- Release air at the connector.
- Loosen wraps or straps.
- Reapply once filled.
- Replace the pad if it still will not fill.
