Before Start-Up
You will need a Hot Spring1.
®
FreshWater
®
Spa Care Kit, which contains test
strips and balancers required each time you fill your spa, along with a Clean
Screen™ pre-filter. Purchase these items from your local Hot Spring dealer.
Fill your spa with water using the Clean Screen pre-filter. 2.
NOTE: If you are not filling your spa for the first time, clean your filters with
FreshWater Filter Cleaner or replace with new filters, before refilling spa.
Once your spa is filled, use a FreshWater test strip to measure the pH, Total 3.
Alkalinity, and Hardness. Use the table below to determine if your spa water is in
the “OK” range. The “OK” ranges listed below are specific for use with the ACE
salt water sanitizing system and may vary from the back of your test strip bottle.
ACE™ Salt Water Sanitizing System Spa Water Guidelines
Parameter Target Min - ”OK” Range - Max
Salt 1000ppm 750ppm 1500ppm
Hardness 50ppm 25ppm 75ppm
Alkalinity 80ppm 40ppm 120ppm
pH 7.4 7.0 7.6
Chlorine 3ppm 3ppm 5ppm
Adjust pH and Total Alkalinity following the instructions in the Water Quality and 4.
Maintenance section of your spa’s Owner’s Manual. The pH, and Total Alkalin-
ity must be in the “OK” range as indicated in the table above, before starting the
ACE system.
The Vanishing Act calcium remover, included with your ACE salt water sanitizing 5.
system, will help you reduce the Hardness level of the water if needed. Rinse the
calcium remover with a garden hose first, then place over the heater return at the
bottom of the spa for up to 24 hours. Flip and reposition the calcium remover over
the heater return after 12 hours.
NOTE: The ACE system start-up procedure can begin while the calcium remover
is in the spa working to decrease Hardness.
IMPORTANT: It is critical that the Hardness level is in the “OK” range of
25-75ppm to ensure effectiveness of the ACE system. Use additional calcium
removers if necessary.
Start-Up and Refill Procedures
At this point your spa should have balanced water, new or properly cleaned filters,
and power. The water care icon on your spa’s main control panel should be flashing,
indicating that action is required.
