ControlOMatic MegaChlor Operating Instructions Manual page 3

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!
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.
