Step 3: Setting the Control Dial
1.
This system is designed to work effectively with a variety of pool equipment as long as the following procedures are followed.
Set the 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 fi t 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.

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 in Step 2 to determine the correct
setting for your pool.
For the fi rst 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.
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.

Find your starting dial setting by matching up the parameters of your
pool on the above chart. A pool with approximately 12,000 gallons
with a 1 horsepower pump running 12 hours a day would require a
starting setting of 4.5.

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.
