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.
Set control dial on Sparco System 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.
This system is designed to work effectively with a variety of pool equipment as long as the following procedures are
followed.

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 the Control Dial
1.
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.

EXAMPLE
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 ½ horsepower pump running 12 hours a
day, would require a starting setting of 2.5.
