ControlOMatic MegaChlor Installation & Operation Manual page 4

MegaChlor is a semi-automated, salt water chlorine generation system specifically designed for swim
spas & pools up to 17,000 Gallons. MegaChlor generates chlorine from a small amount of ordinary salt
(Sodium Chloride, NaCl) dissolved in the water. The amount of salt added is very small in relation to the
volume of the water in the pool. It's about 90% less concentrated than ocean water and below the typical
taste level of most humans. The small addition of salt also benefits users by providing a softening effect on
the water, leaving hair and skin feeling smoother and healthier than with traditional sanitizing products. A
minimum of only 2.5 cups of salt per 100 gallons of water is all it takes for MegaChlor to produce fresh,
pure chlorine leaving your water clean and clear day after day!
MegaChlor produces chlorine in its pure form using electrolysis in order to sanitize the pool/spa water.
MegaChlor has two versions: MegaChlor and MegaChlor-CD. The standard MegaChlor works on a timed
cycle and the -CD version turns on when the chlorine is gone. The only difference is the electrode, the -CD
version has a chlorine sensor that measures when the chlorine is gone. After the salt is converted to
chlorine, the chlorine will later be converted back to salt, keeping the salt level steady.
Water Preparation & Maintenance
To ensure proper operation it is recommended to balance the water prior to installing the MegaChlor.
Use the levels in the following table as a guide to balancing the water. Use the test strips to measure water
chemistry and verify that the water has been balanced properly. Cleaning the filter is recommended but not
required unless the previous sanitizer was 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 water for the health and safety of its users. MegaChlor may significantly reduce the
amount of maintenance required, but chemical check-ups including chlorine levels and PH are
recommended before each use. Proper water maintenance will prolong the life of MegaChlor and the pool
or spa. The following table describes generally accepted optimum water chemistry for portable pools and
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 water is manually shocked after high usage (example: after a party
with multiple users), or biweekly if used frequently. Always remember to leave the water circulating for
several hours before retesting. Phosphates in the water water will increase the demand for chlorine and
will reduce the life expectancy of the generator. Remove Phosphates upon start up and each month there
after. Phosphate Remover can be purchased at any local Pool & Spa supply store.
WARNING: Consistent chlorine levels above 5.0 PPM or calcium hardness below 200 may lead to
corrosion of metal components in the pool or spa.
