ACE Salt Water Sanitizing System  

 

      

 Page 1

Welcome

Congratulations on your purchase of the ACE

®

 salt water sanitizing system which 

generates chlorine and powerful mixed oxidants naturally, making it easy to keep 

spa water sparkling clean. With proper care, the ACE system allows spa water to 

last much longer than traditional water care - up to 12 months.* By extending the life 

of your spa water, you will drain and refill your spa less frequently - another way the 

ACE system saves you time and helps conserve water.

Overview of the ACE System

The ACE salt water sanitizing system features a diamond electrode cell that auto-

matically generates chlorine and mixed oxidants. The ACE system does not contain 

a chlorine sensor, so the amount of chlorine generated is based on the output level 

you select. The system eliminates the need for daily or weekly maintenance, while 

providing dramatically enhanced water quality.

helpful videos, visit www.Hotspring.com/ACE. 

Spa Owner Responsibilities

Maintain balanced

 spa water. Always maintain balanced spa water. The pH and 

alkalinity levels must stay within the OK range. Use a test strip weekly to check.

Keep total hardness at or below 50 ppm

. High levels of calcium in spa water will 

lead to more frequent cell cleaning and replacement. Use a test strip to check hard-

ness after topping off spa water. Use the Vanishing Act calcium remover as needed.

Test for chlorine regularly

. Use a test strip weekly to check for chlorine in the 

water. The recommended chlorine level is 3 ppm. Add FreshWater Concentrated 

Chlorinated Granules to supplement the system when needed.
