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. This
ususally requires 8 to 12
hours. Check with your
dealer for the proper
circulation time for your
pool.

2.

• Before beginning with any pool care program, you must
first balance your pool water. Take a water sample to your
local pool professional or use a complete test kit that will
test for the following important elements

Water Balance Guidelines

3.

• If your fill water is high in metals, use a sequestering
agent or metal out at start-up only before inserting a Pac.
See your local dealer for details on using these products
and always follow manufacturer’s directions carefully.

• Afer your pool is up and

4.

running smoothly, continue to
test your water for pH, total
alkalinity and chlorine and
maintain its balance by adding
any necessary adjustment
products (see your dealer for
details).

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

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

• Add a stabilizer or conditioner to

1.

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.

4

SETTING CONTROL DIAL

• Set control dial by matching up the parameters

4.

your individual pool needs. See #5 for below for adjusting
directions. IMPORTANT: Pump run times less than 8
hours could result in under chlorination due to inadequate
flow through the System.

of your pool on the chart below. THIS IS A STARTING
POINT ONLY and may need to be adjusted to fit

2.

• Shock the pool with chlorine to rid
the water of all contaminants before
beginning

. Follow manufacturer's

directions carefully.

• This step is very important to
start-up. Use chlorine shock only.

• Do not add shock in or near the skimmer or into the Cycler
as it could damage equipment, risk potential explosion or
discolor your pool surface.

pool water daily for free

setting. Continue to test
weekly throughout the season.

Test Strips

Test strips recommended.

• After each testing, adjust the

4

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.

3.

• When chlorine reading is
down to 1.0 ppm, which may
take a few days, insert pac
into cycler.

(Follow directions
on Page 6.)

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

• Shock pool every two weeks or as

6.

needed to maintain water quality. Follow
label directions on the shock treatment
used.

• Do not add shock in or near the skimmer

or into the Cycler as it could damage
equipment, risk potential explosion or
discolor your pool surface.

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

0. This reduces the flow of
water into the unit when the
cap is open so isolation
valves are unnecessary.

• Unscrew knob to relieve
pressure.

B. If using a 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.

• The Pac is made of HDPE
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.
