MegaChlor includes 10 power level settings that are set based on water volume, usage and testing. The

SELECTING THE RIGHT POWER LEVEL
Selecting the right power level requires some testing and adjustment. There are many factors that affect the
sanitizing needs of a pool such as: use, number of people, if there is an Ozone Generator, temperature, last
drain and refill, does it have a cover, cyanuric acid or stabilizer, etc. However, after the testing and adjustment
period, MegaChlor will take care of your sanitation needs day after day with minimal adjustments. As a
starting point, please program MegaChlor and set the power
level to the general recommendations shown in the table.
Test the Chlorine Level with test strips after 1 to 2 days. When
testing, always try to measure at the same time of the day. If
the chlorine level is LOW, increase the power level by one
level. If the chlorine level is HIGH decrease the power level by
one level. Wait a day or so after this initial adjustment, re-test
and repeat as necessary until a consistent chlorine residual has
been achieved. If the chlorine level is VERY high or VERY low,
adjust by 2 levels, as needed.
IMPORTANT NOTE: If the chlorine level is zero 24 hours after installation, the initial chlorine demand may be
above what MegaChlor can produce to break away from zero. In this case, manually add chlorine or shock
(according to the company product label) to assist in the initial set-up.
If conditions change on the pool usage make sure to adjust the power level. If usage significantly increases,
(return from vacation, etc) it is important to adjust the power level up accordingly. Always retest and adjust
the power level as needed.
