3.4 Bonding
WARNING
The National Electrical Code (NEC) and Canadian
Electrical Code (CEC) requires that pool equipment
be bonded to each other. Make sure to check your
local codes to determine if the NEC, CEC, and/
or other local installation codes are enforced by
the Authority Having Jurisdiction (AHJ) or the local
competent authorities in Canada. A solid copper
bonding conductor min. 8.37 mm² (8 AWG), 13.3
mm² (6 AWG) in Canada, shall be used for bonding
the power pack to a permanent bonding connection
that is acceptable to the AHJ or local competent
authority. A bonding conductor is included with this
product. Refer to your locally enforced codes for the
acceptable bonding wire gauge. Each piece of non-
related pool equipment requiring a ground should also
be bonded to the common, approved bonding point.
To avoid property damage, serious injury or death,
NEVER use the chassis backplate of the power pack
to ground any other equipment.
Attach the bonding point located on the bottom of the
chassis backplate to a common bonding point. Do not
use the power pack as the common bonding point.
Each piece of non-related pool equipment requiring a
ground should also be bonded to the common, approved
bonding point. There should be one bonding connection
to the power pack. In Canada, the Canadian Electrical
Code (CEC) dictates that the bonding conductor be,
minimum 13.3 mm2 (6 AWG).
National Electrical Code® (NEC®) requires bonding of
the Pool Water for Permanently Installed Pools. Where
none of the bonded pool equipment, structures, or
parts are in direct connection with the pool water; the
pool water shall be in direct contact with an approved
corrosion-resistant conductive surface that exposes not
less than 5800 mm² (9 in²) of the surface area to the
pool water at all times. The conductive surface shall be
located where it is not exposed to physical damage or
dislodgement during usual pool activities, and it shall be
bonded in accordance with the bonding requirements of
NEC Article 680. Refer to your locally enforced codes for
any additional bonding requirements.

Section 4. Pool Water
Preparation
4.1 Determining Pool Size (Gallons of
Water in Your Pool)
• Rectangular Pools
Average length (feet) x average width (feet) x
average depth (feet) x 7.5 = gallon capacity.
• Circular Pools
Diameter (feet) x diameter (feet) x average depth
(feet) x 5.9 = gallon capacity.
• Oval Pools
Long diameter (feet) x short diameter (feet) x
average depth (feet) x 5.9 = gallon capacity.
• Sloping Sides
Multiply total gallons by 0.85 = gallon capacity.
4.2 Determining Pool Size (Litres of Water
in Your Pool)
• Rectangular Pools
Average length (metres) x average width
(metres) x average depth (metres) x 1000 = litres
capacity.
• Circular Pools
Diameter (metres) x diameter (metres) x average
depth (metres) x 790 = litres capacity.
• Oval Pools
Long diameter (metres) x short diameter (metres)
x average depth (metres) x 790 = litres capacity.
• Sloping Sides
Multiply total litres by 0.85 = litres capacity.
4.3 Chemistry You Need to Know
• Chlorine Stabilizer (cyanuric acid) is needed
to maintain proper levels of chlorine. Most
non-stabilized chlorine is destroyed bythe UV
radiation from the sun within two (2) hours.
Chlorine stabilizer should bemaintained between
10 - 50 ppm. For indoor pools, it is not necessary
to add chlorine stabilizer to the swimming pool
water.
• Nitrates can cause extremely high chlorine
demands and will deplete chlorine from your
swimming pool. In some cases nitrates may even
lower your chlorine levels to zero. Your local
pool professional can test for nitrates. Make sure
nitrates are not present in your pool.
• Metals (some metals) can cause loss of chlorine
stain your pool. Have your local pool professional
check for metals and recommend methods of
removal.
• Chloramines should not be present in pool
water. When organic materials combine with free
chlorine, chloramines are formed. This ties up
the free chlorine in your pool and does not allow
the chlorine in your pool to disinfect. Chloramines
also cloud pool water and burn the eyes. Shock
to remove chloramines at the initial startup of
the pool.

Polaris® AutoClear® SC (PAGSC20K) Salt Chlorinator - Installation and Operation
Manual
ENGLISH
• Super Chlorination burns out the organic
material that has combined with chlorine
which frees the chlorine for sanitizing. This is
accomplished byraising the chlorine level quickly
and dramatically. To super chlorinate the pool
using the chlorine generating device, set the
chlorine production to 100% and then set the
pump and the cell to run for 24 hours.
• Shocking (Superoxidation) is also a means
of burning out the organic material that has
combined with chlorine.This method involves
the manual addition of chemicals to quickly raise
the level of chlorine. When the chlorine level is
quickly raised to 5 - 15 ppm the pool water is said
to have been shocked.
NOTE: On initial startup of a pool, it is best to shock from an
alternate source, i.e., use a shock treatment available at
your local pool supplier.
• The pH condition resulting from the operation
of a salt water chlorination system is close to
neutral. However, other factors usually cause the
pH of the pool water to rise. Therefore, the pH in
a pool chlorinated by a salt water system tends to
stabilize at approximately 7.6. If the pool pH rises
above 7.6 have a pool professional test to see if
other factors such as high calcium hardness or
total alkalinity are the cause and then balance
accordingly.
• Total Dissolved Solids (TDS) Adding salt
to pool water will raise the TDS level. While
this does not adversely affect the pool water
chemistryor clarity, the pool water professional
testing for TDS must be made aware salt has
been added for the sanitizing system. The
individual performing the TDS test will then
subtract the salinity level to arrive at the correct
TDS level.
• New pool water in a recently filled or newly
refinished pool may contain undesirable
matter which could interfere with the salt water
chlorinator’s ability to sanitize properly. Make
sure the water is tested by a pool professional
and properly balanced before turning on the
chlorinator system. New plaster pools have a
constant acid demand for six (6) months.Test
often and maintain a proper pH to avoid excess
scaling of the cell.
• Sequestering Agents can be used to
compensate for source water which may have
unusually high calcium hardness. High calcium
hardness can contribute to scale formation in
the pool. Sequestering agents will help keep
minerals in solution and under some conditions
can prevent scaling from happening. Consult
your pool professional about the use of a
sequestering agent.
4.4 Optimum Pool Water Conditions
• In accordance with Association of Pool and Hot
Tub Alliance (PHTA) standards, we recommend
the following water balance conditions be
maintained on an ongoing basis to protect the
pool finish and the equipment and to ensure the
pleasing appearance of the water. The chlorine
generating device is warranted to operate
properly only if the following conditions are met:
Free Chlorine
Pools: 1 - 3 ppm. Continuous
exposure to levels above 3.0
ppm may cause corrosion of pool
metals.
Combined
Chlorine
(Chloramines)
None
(Super chlorinate to remove all
chloramines.)
pH
7.4 - 7.6
(Use muriatic acid to lower pH and
soda ash to raise pH.)
Chlorine
Stabilizer
(Cyanuric
Acid)
10 - 50 ppm
(For outdoor pools only.)
Total
Alkalinity
80 - 120 ppm
Calcium
Hardness
Pools: 200 - 300 ppm
Metals (Iron,
Manganese)
None
Nitrates
None
Phosphates
None
4.5 Chlorine Testing
Use a home test kit or ask your pool professional to
test your water. It is recommended that chlorine test
samples be taken from two (2) places, described below.
Compare the two (2) samples. A higher level should be
found at the pool return line. The higher level at the pool
return line indicates the salt water chlorinator system is
producing chlorine.
1. At the pool return line.
2. 46 cm (18 in.) below the surface and well away
from the pool return line.
CAUTION
Never use dry acid to adjust pH in arid geographic
areas with excessive evaporation and minimal dilution
of pool water with fresh water. A buildup of by-
products can damage the electrolytic cell.

4.6 Salt (NaCl Sodium Chloride)
When to Add Salt
Add salt to the pool if the salt is too low (see Table
1) or if salt indicator light turns on. For a new pool or
newly resurfaced pool, it is recommended to wait at
least 30 days (surface should be completely cured)
before adding salt. Do not run the chlorinator at this
time. Manually chlorinate the pool. Contact your
dealer for recommendations. Follow the pool surface
manufacturer’s guidelines for your particular pool. For
vinyl and fiberglass pools, salt can be added at start up.
What Type of Salt to Use
• The purer the salt, the better the life and performance
of the electrolytic cell. Use a salt that is at least 99.8%
pure NaCl. The salt is an evaporated, granulated,
food quality, non-iodized salt. Consult your salt
supplier.
• Avoid using salt with anti-caking agents (sodium
ferrocyanide, also known as YPS or yellow prussiate
of soda) that could cause some discoloration of
fittings and surface finishes in pool.
• Water conditioning salt pellets are compressed forms
of evaporated salt and may be used but will take
longer to dissolve.
• Do not use calcium chloride as a source of salt. Use
sodium chloride only.
• Do not userock salt because insoluble impurities
mixed with the rock salt can shorten the life of the unit.
How Much Salt to Use
Use salinity test strips, a TDS/salinity meter, or another
reliable method to test the salinity of the pool water.
Once the existing salinity has been established, use
Table 1 to determine the amount of salt to add to reach
the desired level. Be conservative when adding salt as it
is easier to add more if needed than it is to dilute if there
is too much salt.
• 3,000 ppm of salt is recommended for optimum water
conditions.
NOTE: In cooler water conditions (less than 18°C (65°F)), it
may benecessary to add more than 4,500 ppm of salt
to keep the “Check Salt” alarm from appearing on the
power pack.
• Minimum salt level is 3,000 parts per million (ppm).
• Low salt concentration below 2,500 ppm will cause
premature cell failure.
• High salt concentration above 6,000 ppm may cause
corrosion damage to pool fixtures.
How to Add Salt to the Pool
1. Turn on pump to circulate pool water.
2. IMPORTANT - Turn the power pack off by pressing
the ON/Off button (OFF will be displayed on the
screen).
3. Test the water for salinity level using test strips,
electronic meter, or by your local pool professional.
4. Use the Table 1 to determine the amount of salt
to add. Be conservative when adding salt as it is
easier to add more if needed than it is to dilute if
there is too much salt.
5. Broadcast salt into pool. Do not add through
skimmer, main drain, or surge tank. Brush the
salt around the pool to facilitate dissolving.
Circulate filter system for 24 hours to ensure even
distribution.
6. After 24 hours, verify correct salt reading by
testing the water salinity level using test strips,
electronic meter, or by your local pool professional.
7. When the salinity level is correct, turn the power
pack on. Press the OUTPUT button to set the
desired production rate.
NOTE: For a new pool or newly resurfaced pool, it is
recommended to wait at least 30 days (surface should
be completely cured) before adding salt. Follow the pool
surface manufacturers guidelines for your particular pool.
For vinyl and fiberglass pools, salt can be added at start
up.
CAUTION
It is important to note that certain materials used
in and around swimming pools may notbe
compatible with chemicals commonly used to
purify pool water (e.g. acids, chlorine, salt,stabilizers,
etc.).
Polaris Pool Systems, Inc. does not warrant or
guarantee that the chlorinated water generated by
the chlorine generating device will not damage or
destroy certain types of plants, decking, coping and
other materials in and around your pool. Before
selecting materials to be used in and aroundyour
pool, please discuss all options withyour contractor
to assess the compatibility of such materials and
chemicals.
Some helpful considerations mayinclude:
Choosing plants that can withstand splash out of
pool water containing chlorine and/or salt and other
water purification chemicals.
All metal components used in and around a pool
should be of a high grade, quality stainless steel.
Careful selection of masonry products. The porosity
and hardness of natural stones varies greatly.
Therefore we recommend you consult with your
builder or stone contractor on the best choice for
stone materials around your pool.
Sealing all masonry products. Professionals
in the stone industry specify that even natural
stone, especially when used outdoors, be sealed
to prevent weathering, staining, and premature
degradation. Consult with your stone or deck
contractor for the proper sealer for the masonry
products you have selected to use around your pool.
For optimal results, sealers should be reapplied on
a regular basis. Reapply the protective sealer on a
schedule per the manufacturer’s instructions.
Use of chemicals other than those recommended
may be hazardous. Follow the chemical
manufacturer’s instructions.

NOTE: The above chart is for general reference only. The recommended stabilizer reading is between 10 - 50
ppm and will vary dependent on geographic climate. Warm, sunny climates will require a stabilizer reading
at the higher end of the given range. Consult your local pool professional for your optimum level. Always add
stabilizer according to manufacturer’s instructions. For indoor pools, it is not necessary to add chlorine stabilizer
to the swimming pool water.
