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 back knob until water appears. Then screw
the knob back in. 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.

2.
For the first week, test the pool
water daily for free chlorine
to ensure correct dial setting.
Continue to test weekly throughout
the season..
After each testing, adjust the dial up by
1/2 increment if the free chlorine reading
has dropped or down by 1/2 increment
if the reading has risen. Continue this
process each day until the reading
stabilizes at your desired level between
1.0- 3.0 ppm. Remember to adjust dial by
1/2 increments only.
Step 3: Setting 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 on Prevail Cycler 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.
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. An above ground pool with approximately
12,000 gallons, with a 1 horsepower pump running 12 hours a day,
would require a starting setting of 2.5.
