ACE Salt Water Sanitizer System Troubleshooting

Attention is needed. Access the ACE system menus on the main control panel to read the status message.

• Use FreshWater test strip. If chlorine is low, manually add granular dichlor (chlorine) as needed, or initiate a chlorine Boost.
• Check filters and clean as needed according to your Owner's manual.
• Use a FreshWater test strip to check spa pH level. Add pH down as needed.

• Check settings. Your use level may require you to increase the setting to a higher number. If use level is at 5, increase spa size will generate more sanitizer.
• Install an ozone unit if the ACE system is running at capacity.

• Check settings. Your use level may require you to decrease the setting to a lower number. If use level is at 1, decreasing spa size will generate less sanitizer.
• Reduce chlorine level by adding 1-cup hydrogen peroxide. Check chlorine level and repeat as needed.

• Water temperature may be low. Allow water temperature to reach 100F/37.5C and re-test.
• Filters may be dirty. Remove cell from filter and place in main tub. Re-test the salt level. If the salt show in the OK range, replace or clean the filters as needed.
• Cell may require cleaning. Review Cell Cleaning section of instructions.
• Cell may need to be replaced.

• Contact IHT Service Dept. at 303-296-7727.
• NOTE: You may continue to use your spa as long as the chlorine level on the FreshWater test strip is in the OK range.
