ControlOMatic ChlorMaker Operating Instructions Manual page 3

ChlorMaker is a semi-automated, salt water chlorine generation system specifically designed for portable spas
up to 1000 Gallons. ChlorMaker generates chlorine from a small amount of ordinary salt (Sodium Chloride,
NaCl) dissolved in the spa water. The amount of salt added is very small in relation to the volume of the water
in the spa. The concentration required for the ChlorMaker is only about 5% of the salt level of ocean water and
below the typical taste level of most humans.
The small addition of salt also benefits spa users by providing a softening effect on the water, leaving hair and
skin feeling smoother and healthier than with traditional sanitizing products. Only 2.5 cups of salt per 100
gallons (379 liters) of water is all it takes for ChlorMaker to produce fresh, pure chlorine leaving your
water clean and clear day after day.
ChlorMaker produces chlorine in its pure form using electrolysis in order to sanitize the spa water. The
ChlorMaker operates on a 3 hour cycle. The chlorine in a spa will dissipate quickly due to the warmer
temperatures of the water, so the ChlorMaker operates with a short 3 hour cycle time to ensure sanitizer levels
are maintained. After the salt is converted to chlorine, the chlorine will later be converted back to salt, keeping
the salt level steady. When you use the spa your body attracts some salt and when you get out the salt level
will drop slightly.
WATER PREPARATION & MAINTENANCE
To ensure proper operation, the spa must be drained, rinsed, refilled with fresh water, and balanced to the
recommended levels indicated in this section before installing the product. Use the included test strips to
measure water chemistry and verify the water is properly balanced. Replacing the filter is recommended, but
not required unless, the spa was previously sanitized with a hydrogen peroxide system. The combination of
hydrogen peroxide and chlorine may cause gum-like build up, water discoloration, and skin irritation.
It is important to properly maintain your spa for the health and safety of all users. Spas are unique in both size
and usage patterns. ChlorMaker will significantly reduce the amount of spa maintenance required, but regular
chemical checkups, including chlorine levels and pH, are recommended. Proper water maintenance will
prolong the life of ChlorMaker and the spa. The following table describes generally accepted optimum water
chemistry for portable spas.
It is recommended that chlorine and PH levels are
checked before each use, or at least once per week
when not in use. Alkalinity, Calcium Hardness, and
Salt Concentration should be checked at least once
per month. It is recommended that the spa is
manually shocked after high usage (example: after a
party with multiple users), or biweekly if used
frequently. Always remember to leave the spa
circulating for several hours before retesting.
Phosphates in the spa water will increase the demand for chlorine and will reduce the life expectancy of the
generator. Remove Phosphates upon start up and each month thereafter. Phosphate Remover can be
purchased at any local Pool & Spa supply store.
WARNING: Consistent chlorine levels above 5.0 PPM (parts per million) or consistent salt
concentration levels above 5,000 PPM may lead to corrosion of metal components in the spa.
WARNING: Consistently low Calcium Hardness levels below 150 PPM may lead to spa equipment
damage and failure. Make sure Calcium Hardness levels are within the recommended range above.
