Display shows ICE or IC, pumps may run automatically even when spa is not in use.

Safety first: Do not disable freeze protection; it prevents plumbing damage.

• Verify operation: The spa will automatically run pumps and sometimes heater to prevent freezing. This is normal when ICE is displayed.
• Keep spa powered: Always leave power on to your Dynasty Spa during freezing weather so freeze protection can operate.
• Check cover and cabinet: Ensure the cover is closed and cabinet panels are in place to retain heat.
• Sensor check: If ICE appears in warm conditions, inspect and test the temperature sensor for accuracy and replace if faulty.
