Step 3: Setting the Control Dial
This system is designed to work effectively with a variety of pool equipment as long as the following procedures are followed.
Set control dial by matching up the parameters of your pool on the chart below. THIS IS A STARTING POINT ONLY and may need
to be adjusted to fit your individual pool needs. See #2 below for adjusting directions.
IMPORTANT:
If using a multi-speed pump,
pump-run times of at least 6 hours per day at high speed are recommended for proper performance.
If running the pump at low speed only or on high speed less than 6 hours, please follow the 24 hour low-speed
directions below.
1.
24 HOUR, LOW-SPEED PUMP-RUN TIME
In order to ensure proper performance when running the
pump on low speed for 24 hours per day or high speed less
than 6 hours per day, bleed the air while the pump is on by
unscrewing the cap knob until water appears. Then screw
the knob back on. Repeat this process each time the cap is
removed for any reason. Set the control dial at 6 and follow
the adjustment directions below to determine the correct
setting for your pool.
For the first week test the pool water
daily for free chlorine with FROG Test
Strips to ensure correct dial setting.
Continue to test weekly throughout the
season.
2.
After each testing, adjust the dial up
by 1/2 increment if the free chlorine
reading has dropped below 0.5 ppm
or adjust down by 1/2 increment
if the reading has risen above 1.0
ppm. Continue this process each
day until the free chlorine reading
stabilizes to at least 0.5 ppm.
Remember to adjust dial by
1/2 increments only in order to
prevent over chlorination which
may bleach pool surfaces.
Use the handle end of cap tool if
the dial is hard to turn.
Find your starting dial setting by matching up the parameters of your
pool on the above chart. An In ground pool with approximately 18,000
gallons with a 1 horse power pump running 6 hours a day at high
speed would require a starting dial setting of 5.

IMPORTANT:
Control dial settings in excess of these
recommendations could result in excess trichlor levels being
discharged into the pool. This can result in bleaching or
discoloration of areas around the pool inlet or in some cases
bleaching or discoloration of the entire pool liner or paint. In
addition, excess trichlor in the pool can create health hazards
to bathers.
