or breathing its fumes. One Pac lasts 2 to 4
weeks.

(Pac sold separately )

Swimming Pool Tips

Start-up and Yearly Maintenance

1.

• Make sure the pool has
adequate circulation. The
pool water must completely
circulate through the pump
and filter at least 1 to 2
times per day. Check with
your dealer for the proper
circulation time for your
pool.

2.

Water Balance Guidelines

pH: 7.2 – 7.8
Total Alkalinity: 60 – 120 ppm
Calcium Hardness: 150 – 400
Total Dissolved Solids: <1500
Stabilizer: 20 – 80 ppm
Free Chlorine: 1.0 – 3.0 ppm

3.

• If your fill water is high in metals, use a sequestering
agent or metal out at pool opening only before inserting a
Pac. Follow manufacturer’s directions.

• Regularly test your water for

4.

pH, total alkalinity and chlorine
and maintain its balance.

• Before beginning,
balance your pool water
using the chart.

5.

• Check the pool's filter gauge
often and periodically clean
filter per the manufacturer's
directions. A dirty filter will slow
the flow of water which could
hamper proper circulation.

Start-up and Operation

1.

2.

• Add a stabilizer or conditioner to
the pool at the beginning of the
season if the stabilizer level is below
20 ppm. This will prevent chlorine
burn off. Follow manufacturer’s
directions carefully.

• Shock the pool with chlorine to rid
the water of all contaminants before
beginning. Follow manufacturer's
directions carefully.

pool water daily for free

setting. Continue to test
weekly throughout the season.
Test strips recommended.

7.

• After each testing, adjust the
dial up by 1/2 increment if the

free chlorine reading has dropped
below 1.0 ppm or adjust down
by 1/2 increment if the reading
has risen above 3.0 ppm.
Continue this process each day

until the reading stabilizes between 1.0 and 3.0 ppm.

Remember to adjust dial by 1/2 increments only in order
to prevent over chlorination which may bleach pool
surfaces.

Replacing a Chlorine Pac

1.

2.

CAUTION Read Carefully – USE ONLY the factory recommended replacement Pac. (See
label.) DO NOT USE any other Pac or bulk chemical tablets in the Cycler. Use of any
other product could result in over chlorination, bleached liners, unsafe pool conditions,
fire or explosion. Warranty will be void if the correct Pac is not used.

• Turn off pump. Turn dial to
Minimum. This reduces the
flow of water into the unit
when the cap is open so iso­lation valves are unneces­sary.

• Unscrew side knob to
relieve pressure.

B. If using a Pac cutting
tool, place curved section
of tool around the narrow
end of one Pac tower and
line up blade on indent.

C. Squeeze the handles
together. Repeat for other
side.

• Use the cap tool included
with Cycler to loosen cap by
hitting the handle with the flat
of your hand counter
clockwise. Stand back upon
removing cap to avoid inhaling
fumes.

• The Pac is made of HDPE #2
plastic. When the Pac is empty,
triple rinse in pool water, drain,
and recycle or wrap in
newspaper and discard in trash.

D. If using a hacksaw to
cut the Pac, line up hack­saw blade on indent and
cut with a smooth sawing
action.
