Section 1. Important Safety Instructions
READ AND FOLLOW ALL INSTRUCTIONS
This device can only be used in swimming pools and swimming pools with a built-in spa. It cannot be used in stand-alone
spas.
All electrical work must be performed by a licensed electrician and conform to all national, provincial, and local codes.
When installing and using this electrical equipment, basic safety precautions should always be followed, including the
following:
WARNING
EQUIPMENT UNDER PRESSURE: Always turn pump off prior to installing or servicing the power pack or cell.
Your pump/filter system is operated under pressure and the pressure must be released before you begin work. Please see
your pump/filter owner’s manual for further instructions
WARNING
To reduce the risk of electric shock, fire or injury, service should only be attempted by a qualified pool service professional.
WARNING
Zodiac AquaPure Ei Series APURE35C chlorine generating devices are designed for domestic (residential) swimming pool
use only. Contrary use could affect performance, void warranty, and may result in property damage, serious injury, or
death.
• Heavy pool (or spa) usage and higher temperatures may require higher chlorine output to maintain proper free
available chlorine residuals.
• Operating a chlorine generator without water flowing through the cell may cause a build up of flammablegases,
resulting in fire or explosion.
• To reduce the risk of injury, do not permit children to operate this device.
• A damaged supply cord should only be replaced by the manufacturer, service agent or electrician.
• When installing and using this electrical equipment, always follow basic safety precautions.
• Before performing installation, disconnect all power.
• Connect to a circuit that is protected by a ground fault circuit interrupter (GFCI).
• Do not install within an outer enclosure or beneath the skirt of a hot tub or spa.
• Do not use this device with bromide products.
WARNING
Installation must be done in accordance with the Canadian Electrical Code (“CEC” or C22.1) and/or any other local and
national installation codes.
RISK OF ELECTRIC SHOCK, FIRE, PERSONAL INJURY, OR DEATH. Connect only to a branch circuit that is
protected by a ground-fault circuit-interrupter (GFCI). Contact a qualified electrician if you cannot verify that the circuit
is protected by a GFCI. Make sure such a GFCI should be provided by the installer and should be tested on a routine
basis. To test the GFCI, push the test button. The GFCI should interrupt power. Push the reset button. Power should be
restored. If the GFCI fails to operate in this manner, the GFCI is defective. If the GFCI interrupts power to the pump
without the test button being pushed, a ground current is flowing, indicating the possibility of electrical shock. Do not use
the device. Disconnect the device and have the problem corrected by a qualified service representative before using.
A wire-binding screw for grounding (labeled) is provided inside the power pack. To reduce risk of electric
shock, connect the ground wire to the grounding points in the power pack and of your electric service or supply
panel with a conductor equivalent in size to the circuit conductors supplying this equipment.

P a g e | 7
The power pack must be interlocked/interconnected with the pool pump motor power source to ensure that the chlorinator
only operates when the pool pump is operating.
WARNING
OperatingtheZodiacAquaPure EiSeriesAPURE35C chlorinegeneratingdevicewithout waterflowthroughtheelectrolyticcell
can cause a buildup of flammable gasses which can result in FIRE OR EXPLOSION.
WARNING
The power pack must be installed at least 1.5 m (5 ft.) vertically off the ground.
The power pack must be installed at least 3 m (10 ft.) from the inside wall of your swimming pool or built-in spa.
WARNING
This appliance is not intended for use by persons with reduced physical, sensory or mental capabilities, or lack of
experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by
a person responsible for their safety. WARNING
To reduce the risk of injury, do not remove the suction fittings of your spa or hot tub. Never operate a spa or hot tub if

least 1 m (3 ft.) from the pool so children cannot use the equipment to access the pool and be injured or drown.
WARNING
People with a medical condition should consult a physician before entering pool or spa water.
Prolonged immersion in hot water may induce hyperthermia. Hyperthermia occurs when the internal temperature
of the body reaches a level several degrees above the normal body temperature of 37°C (98.6°F). The symptoms of
hyperthermia include dizziness, fainting, drowsiness, lethargy, and an increase in the internal temperature of the body.
The effects of hyperthermia include:
•Unawareness of impending danger
•Failure to perceive heat
•Failure to recognize the need to exit spa
•Physical inability to exit spa
•Fetal damage in pregnant women
•Unconsciousness resulting in a danger of drowning
WARNING
To Reduce the Risk of Injury -
•Maximum spa water usage temperature is 40°C. Bathing in spa water at 40°C should not exceed 15 minutes.
Water temperatures between 38°C (100°F) and 40°C (104°F) are considered safe for a healthy adult. Lower water
temperatures are recommended for young children and when spa use exceeds 10 minutes.
•Since excessive water temperatures have a high potential for causing fetal damage during the early months of
pregnancy, pregnant or possibly pregnant women should limit spa water temperatures to 38°C (100°F).
•Before entering a spa or hot tub, the user should measure the water temperature with an accuratethermometer
since the tolerance of water temperature-regulating devices varies.

P a g e | 8
•The use of alcohol, drugs, or medication before or during spa or hot tub use may lead to unconsciousness with the
possibility of drowning.
•Obese persons and persons with a history of heart disease, low or high blood pressure, circulatory system
problems, or diabetes should consult a physician before using a spa.
•Persons using medication should consult a physician before using a spa or hot tub since some medication may
induce drowsiness while other medication may affect heart rate, blood pressure, and circulation.
WARNING
•For proper sanitation, spas must be completely drained periodically. The number of days between COMPLETE
SPA DRAINAGE is equal to the volume of spa water in litres, divided by 10 times the maximum number of daily
spa users. Refill spa with water and repeat DIRECTIONS FOR USE of the device.
•People with infectious diseases should not use a spa or hot tub.
•To avoid injury, exercise care when entering or exiting the spa or hot tub.
•Do not use drugs or alcohol before or during the use of a spa or hot tub to avoid unconsciousness and
possible drowning.
•Pregnant or possibly pregnant women should consult a physician before using a spa or hot tub.
•Water temperature in excess of 38°C (100°F) may be injurious to your health.
•Before entering a spa or hot tub measure the water temperature with an accurate thermometer.
•Do not use a spa or hot tub immediately following strenuous exercise.
•Prolonged immersion in a spa or hot tub may be injurious to your health.
•Do not permit any electric appliance (such as a light, telephone, radio, or television) within 1.5 m (5 ft.)of
a spa or hot tub.
•The use of alcohol, drugs or medication can greatly increase the risk of fatal hyperthermia in hot tubs and spas.
•Water temperature in excess of 38°C (100°F) may be hazardous to your health.
CAUTION
•This device is intended for use with permanent swimming pools and swimming pools with a built-in spa. It cannot
be used in stand-alone spas. Do not use with storable pools. A permanently-installed pool is constructed in or on
the ground or in a building such that it cannot be readily disassembled for storage. A storable pool is constructed
so that it is capable of being readily disassembled for storage and reassembled to its original integrity.
CAUTION
•It is important to note that certain materials used in and around swimming pools and spas may not be compatible
with chemicals commonly used to purify pool and spa water (e.g. acids, chlorine, salt, stabilizers, etc.).
•Zodiac Pool Systems, Inc. does not warrant or guarantee that the chlorinated water generated by the Zodiac
AquaPure Ei Series APURE35C chlorine generating device will not damage or destroy certain types of plants,
decking, coping and other materials in and around your pool and/or spa. Before selecting materials to be used in
and around your pool and/or spa, please discuss all options with your contractor to assess the compatibility of
such materials and chemicals.
•When mixing acid with water, ALWAYS ADD ACID TO WATER. NEVER ADD WATER TO ACID.
•Some helpful considerations may include:
•Maintaining high salt and chlorine levels above recommended range can contribute to corrosion of pool or spa
equipment.
•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.

P a g e | 9
•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 or spa.
•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 orspa.
•For the optimal results, sealers should be reapplied on a regular basis. Reapply the protective sealer on aschedule
per the manufacturer’s instructions.
•Use of chemicals other than those recommended may be hazardous. Follow the chemical manufacturers
instructions.

3.4 Wiring the Power Pack to Power Source
WARNING
When using electrical products, basic precautions should always be followed, including the following:
• DANGER: RISK OF ELECTRIC SHOCK WHICH CAN RESULT IN SERIOUS INJURY OR DEATH. Before
attempting installation or service, ensure that all power to the device is disconnected/turned off at the circuit breaker.
Connect only to a circuit protected by a ground-fault circuit-interrupter (GFCI).
• Grounding is required. The unit should be installed by a qualified service representative and should beproperly
grounded and bonded (See Section 3.5, Bonding).
• To avoid property damage, serious injury or death, never use the chassis backplate of the power pack to ground any
other equipment.
• Install to permit access for servicing.
•Please read all cautions and safety instructions in the Important Safety Instructions section. Before attempting any
electrical wiring, be sure to read and follow safety instructions. Wiring should only be attempted by a qualified
professional.
1. Wire power pack to pool pump power source using 3.3 mm2(12 AWG) insulated wire and conduit. Wire the power
pack to the LOAD side of a pump or the LOAD side of the pool pump timer relay so that the chlorinator can only
come on when the pool pump comes on (see Figure 18).
2. Attach the third wire (ground) from the electrical panel to the ground point inside the power pack. Additionally,
applicable local and/or National installation codes may require the equipment to be properly bonded to other pool
equipment or to a bonding grid. Bonding per Section 3.5 must also be accomplished to ensure personal safety and
safety of equipment.
3.5 Bonding
Canadian Electric Code (CEC) requires pool equipment to be bonded to each other. Check your local codes to determine
if other local installation codes are enforced by the Authority Having Jurisdiction (AHJ). A solid, copper 8.37 mm2(8
AWG) wire is recommended, per the CEC, for bonding the power pack to a permanent bonding connection that is
acceptable to the local AHJ. Refer to your locally enforced codes for the acceptable bonding wire gauge. 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. CEC dictates that the
bonding conductor be, minimum 13.3 mm2(6 AWG).
3.6 Connection to an AquaLink RS Control System or PDA (Optional)
The AquaLink RS or PDA is a multi-function pool controller which can fully control the function of the Zodiac AquaPure
Ei Series APURE35C chlorine generating device. Adjustment of the chlorine production rate can be controlled from the

4. Thread the controller cable through the hole. A grommet may be necessary depending on the size of the
cable being used.
5. Attach a cable tie to the controller cable as shown (see Figure 19).

6. In the AquaLink®RS or PDA power center, wire the power pack directly to the LOAD SIDE of the filter
pump relay (see Figure 20).
7. The Jandy AquaLink®RS or PDA and power pack use a four (4) wire connection to communicate and can
be wired up to 152.4 m (500 ft) apart. Any outdoor rated four conductor cable, minimum 0.33 mm2(22
AWG), can be used. Locate the appropriate screw terminals on the circuit board and wire the power pack to
the AquaLink RS or PDA red 4-pin terminal bar (see Figure 21).
NOTE The screw terminals on the AquaLink RS or PDA are removable to aid in installation.
3.6.3 Testing the Connection
Once the power pack has been wired to the AquaLink RS Control System or PDA, follow these steps to test the
connection:
1. Apply power to the power pack and the AquaLink RS Control System or PDA.
2. Wait about 20 seconds. If the connection was successful, a Ŧ symbol will appear in the top right corner of the
power pack display.
NOTE If the power pack does not connect to the controller, turn the power off to both devices and repeat steps 1 and 2. If
the power pack still does not connect to the controller, re-check the wiring connections (see Section 3.6.2) and the
controller setting on the power pack (see Section 3.6.1).
NOTE Ensure the locking ring is level when engaging the threading clamp (see Figure 15).
3.7 Bypass Plumbing Instructions: If Flow Rate Exceeds 348 L/min (92 GPM)
WARNING
Ifflow rate exceeds348 L/min (92 gpm), the cell must be plumbed on bypass otherwise it may result in property damage, personal
injury, or death.
NOTE Pool pumps greater than 2 HP may produce flow rates exceeding 348 L/min (92 gpm). If you are unsure of the
flow rate of your pool pump, contact your dealer for assistance.
The maximum flow rate for the cell is 348 L/min (92 gpm). If flow rate exceeds 348 L/min (92 gpm), the cell MUST be
plumbed on bypass (see Figure 22). A control valve must be installed to regulate the flow through the cell. It can be
installed on the inlet side of the cell or between the inlet and discharge side of the bypass piping. The proper flow will be
achieved by adjusting the handle of the valve until the red “No Flow” light has turned off and all large air bubbles are
cleared from the cell.
3.8 Split Return Plumbing Instructions: For Infloor Cleaning Systems
If the chlorinator is used with an in-floor cleaning system, it must be installed in a separate dedicated return line or
damage to the chlorinator will occur.
NOTE Do not install the chlorinator on in-floor systems that do not have a dedicated pool return as shown in Figure 23.
3.9 Alternative Installation (When Pipe is Obstructed)
If the only suitable length of pipe is obstructed, such as on a multiport valve often found on a sand filter, it is acceptable to
‘lean’ the cell over up to a maximum of 45 degrees (see Figure 24). Mark the feeder holes in the same angle that the cell
will be leaning to ensure that you drill in the right position.

Section 4. Pool Water Preparation
4.1 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 785 = litres capacity.
• Oval Pools
Long diameter (metres) x short diameter (metres) x average depth (metres) x 785 = litres capacity.
• Sloping Sides
Multiply total litres by 0.85 = litres capacity.
4.2 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.
4.3 Chemistry You Need to Know
• Chlorine Stabilizer (cyanuric acid) is needed to maintain proper levels of chlorine. Most non-stabilized chlorine is
destroyed by the UV radiation from the sun within two (2) hours. Chlorine stabilizer should be maintained 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. Insome
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 and 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 thepool.
• Super Chlorination burns out the organic material that has combined with chlorine which frees the chlorine for
sanitizing. Super Chlorination is accomplished by raising the chlorine level quickly and dramatically. To super
chlorinate the pool using the Zodiac AquaPure Ei Series APURE35C 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 (use a registered or scheduled source of sodium dichlor,calcium

P a g e | 17
hypochlorite, liquid chlorine or trichlor) 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 using either a shock treatment or a registered or scheduled
source of sodium dichlor, calcium hypochlorite, liquid chlorine or trichlor available at your local poolsupplier.
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.
• 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 balanceaccordingly.
• Total Dissolved Solids (TDS). Adding salt to pool water will raise the TDS level. While this does not adversely
affect the pool water chemistry or 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. CAUTION
It is important to note that certain materials used in and around swimming pools and spas may not be compatible with
chemicals commonly used to purify pool and spa water (e.g. acids, chlorine, salt, stabilizers, etc.).
Zodiac Pool Systems, Inc. does not warrant or guarantee that the chlorinated water generated by the Zodiac AquaPure Ei
Series APURE35C chlorine generating device will not damage or destroy certain types of plants, decking, coping and
other materials in and around your pool and/or spa. Before selecting materials to be used in and around your pool and/or
spa, please discuss all options with your contractor to assess the compatibility of such materials and chemicals.
Some helpful considerations may include:
•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 or spa.
•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 orspa.
•For optimal results, sealers should be reapplied on a regular basis. Reapply the protective sealer on a scheduleper
the manufacturer’s instructions.

P a g e | 18
•Use of chemicals other than those recommended may be hazardous. Follow the chemical manufacturers
instructions.
•Maintaining high salt and chlorine levels above recommended range can contribute to corrosion of pool or spa
equipment.
4.4 Optimum Pool Water Conditions
In accordance with Association of Pool and Spa Professionals (APSP) standards, we recommend the following water
balance conditions be maintained on an on-going basis to protect the pool finish and the equipment and to ensure the
pleasing appearance of the water. The Zodiac AquaPure Ei Series APURE35C is warranted to operate properly only if the
following conditions are met:
Free Available Chlorine 1.0 - 3.0 ppm.
pH 7.2 - 7.6
Total Alkalinity 100 - 120 ppm
Calcium Hardness 200 - 300 ppm
Salt 4,000 - 4,500 ppm
Cyanuric Acid (for outdoor pools only) 10 - 50 ppm (for outdoor pools only).
4.5 Chlorine Testing
If additional chlorine is required due to heavy bather loads, use sodium dichlor, calcium hypochlorite, liquid chlorine
or trichlor to maintain an appropriate chlorine residual in the water. Use a home test kit or ask your pool professional to
test your water. Check the expiry date of the test kit as test results may be inaccurate if used after that date. 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.
4.6 Salt (NaCl Sodium Chloride)
4.6.1 When to Add Salt

manufacturer’s guidelinesfor your particular pool. For vinyl and fiberglass pools, salt can be added at start up.
4.6.2 What Type of Salt to Use
• The purer the salt, the better the life and performance of the electrolyticcell. 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-cakingagents (sodium ferrocyanide, also known asYPS or yellow prussiate of soda)that
could cause some discolouration of fittings and surface finishes inpool.
• 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 chlorideonly.

P a g e | 19
• Do not use rock salt because insoluble impurities mixed with the rock salt can shorten the life of the unit.
• Do not use this device with bromide products.
4.6.3 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.
•4,000 ppm of salt is recommended for optimum water conditions.
NOTE In cooler water conditions (less than 18°C [65°F]), it may be necessary to add more than 4,500 ppm of salt to keep
the “Check Salt” alarm from appearing on the power pack.
• Low salt concentration below 3,000 ppm will cause premature cell failure.
• High salt concentration above 6,000 ppm may cause corrosion damage to pool fixtures.
