Important Safety Information
WARNING: Consult with a healthcare professional before using this device, especially if you have pre-existing medical conditions or are taking medications. Improper use of cold therapy can lead to adverse effects such as skin damage or frostbite.
- Do not apply cold therapy directly to skin for extended periods without a barrier.
- Monitor skin condition frequently during treatment.
- Discontinue use and consult a physician if you experience unusual pain, numbness, or skin discoloration.
- Statements regarding dietary supplements have not been evaluated by the FDA and are not intended to diagnose, treat, cure, or prevent any disease or health condition.
Product Components
The Ossur Cold Rush Therapy Machine System includes the main unit, power adapter, and tubing. Therapy pads are typically sold separately to allow for customization based on treatment area.


Setup Instructions
- Prepare the Unit: Place the Cold Rush unit on a stable, level surface.
- Add Water and Ice: Open the lid and fill the reservoir with cold water up to the indicated fill line. Then, add ice. Using frozen water bottles instead of loose ice can help maintain colder temperatures for longer and simplify cleaning.
- Connect Therapy Pad: Attach the desired therapy pad (sold separately) to the insulated tubing connectors. Ensure a secure connection to prevent leaks.
- Position Therapy Pad: Place the therapy pad on the affected body part. Use the provided straps or wraps to secure the pad in place, ensuring comfortable contact with the skin. A protective barrier (e.g., a thin cloth) between the pad and skin is recommended.
- Power On: Connect the power adapter to the unit and then plug it into a standard electrical outlet. Turn the unit on using the power switch.

Operating Instructions
Once the unit is set up, it will begin circulating cold water through the therapy pad. The flow control knob allows for adjustment of the water flow rate.
- Treatment Duration: Follow your healthcare professional's recommendations for treatment duration. General cold therapy unit safety precautions suggest treatment durations of up to 6 hours.
- Flow Control: Adjust the flow control knob to achieve a comfortable and effective cold sensation. Higher settings increase water flow.
- Monitoring: Regularly check the skin under the therapy pad for any signs of irritation, excessive cold, or discoloration.



Maintenance
- Cleaning: After each use, empty the water and ice from the reservoir. Clean the reservoir and tubing with mild soap and water. Rinse thoroughly.
- Drying: Allow all components to air dry completely before storage to prevent mold or mildew growth.
- Storage: Store the unit in a cool, dry place. If storing for an extended period, consider flushing the system with distilled water before storage to prevent mineral buildup in the pump.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit does not turn on. | Power cord not connected, power outlet malfunction, unit switch off. | Ensure power cord is securely plugged in. Check power outlet with another device. Verify power switch is in the 'ON' position. |
| No water flow or weak flow. | Insufficient water in reservoir, kinked tubing, air in system, pump obstruction. | Add more water. Check tubing for kinks. Lift and lower the therapy pad to help release air. Clean the system if mineral buildup is suspected. |
| Water is not cold enough. | Insufficient ice, too much water, prolonged use. | Add more ice or replace melted ice. Ensure proper water-to-ice ratio. Consider using frozen water bottles for longer-lasting cold. |
| Leaking from connections. | Loose connections, damaged O-rings. | Ensure all tubing and pad connections are securely fastened. Inspect O-rings for damage and replace if necessary. |
