Features & Settings

Output Level:

The ACE system cleans the water throughout the day. The output setting of 0 -10 de-

termines how long the cell runs each day. Observe your usage patterns and measure 

the chlorine level before each use to guide your output setting. Adjust output up or 

down to increase or decrease output. Keep your setting as low as possible to main-

tain 1-5 pm chlorine. Use Boost or add Freshwater Concentrated Chlorine Granules 

for occasional high use situations.  

Output Settings

 

0  

No output/System off

 

Vacation/low output mode

 

2-7 

Normal use settings (recommended)

 

8-9 

High use settings 

 

10 

Maximum system output, equal to Boost (system runs constantly)

Turning the ACE System off

 

By setting Output to 0, the system will stop generating sanitizers. You will need to 

manually maintain the sanitizer level using FreshWater Concentrated Chlorinated 

Granules if the ACE system is off. 

Vacation or limited use

When the spa is not going to be in use, shock the spa by increasing chlorine to 3-5 

ppm and then run the automatic clean cycle. Clean or replace filters. Lower Output to 

2. For extended vacations, lower Output  to 1 for low output mode. 

Boost:

The Boost feature temporarily increases the output setting to the maximum level for 

24 hours.  The system returns to the previous output setting once the Boost cycle is 

over. Use the Boost function to gradually increase the chlorine level prior to a high 

use situation, or anytime the chlorine level is below 1-5 ppm.  
A Boost will have a greater impact when the output setting is set to a low level, and 

less of an impact when the output setting is high. Freshwater Concentrated Chlorine 

Granules can be added to create an immediate chlorine residual to remove bather 

load and assist the ACE system in building a sanitizer residual.

To increase the chlorine level:

1.  In the ACE Menu, press the 

ON

 ▲

 button to enter the BOOST menu. 

2.  Press the 

OFF

 ▼

 button twice to select and confirm the boost. The BOOST 

icon will flash to indicate that the setting has been updated.  The system 

will automatically initiate a salt test before the boost cycle.  Once the test is 

complete (up to 20 seconds) the bOOST screen will flash to indicate that the 

system is boosting.
