Section 1. Important Safety Instructions
READ AND FOLLOW ALL INSTRUCTIONS
1.1 Safety Instructions
All electrical work must be performed by a licensed electrician and conform to all national, state, and local
codes. When installing and using this electrical equipment, basic safety precautions should always be
followed, including the following:
DANGER
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 the suction fittings are broken
or missing. Never replace a suction fitting with one rated less than the flow rate marked on the equipment assembly.
WARNING
When mixing acid with water, ALWAYS ADD ACID TO WATER. NEVER ADD WATER TO ACID.
WARNING
To reduce the risk of electric shock, fire or injury, service should only be attempted by a qualified Pool Service Professional.
WARNING
Do not operate electrolytic cell without proper flow or water circulation. A buildup of flammable gases would result in hazardous conditions.
WARNING
RISK OF ELECTRIC SHOCK, FIRE, PERSONAL INJURY, OR DEATH
• Installation must be done in accordance with the National Electrical Code® (NEC® , NFPA-70) and/or any other applicable local and national
installation codes.
• A green colored terminal (or a wire connector marked “G”, “GR”, “Ground” or “Grounding”) is provided within the terminal compartment. To
reduce risk of electric shock, connect this terminal or connector to the grounding terminal of your electric service or supply panel with a conductor
equivalent in size to the circuit conductors supplying this equipment.
• Power supply must be interconnected with pool pump motor power source. This insures the chlorinator and pool pump will turn on and off
together.
• Use of chemicals other than those recommended may be hazardous. Follow the chemical manufacturers’ instructions.
• If the Flow/Temp/Salinity sensor is not installed in the electrolytic cell then it is recommended that it is installed in the same piping as the cell, up
stream from the cell, and without any valves or diverters between them.
• The Flow/Temp/Salinity sensor must be mounted as shown in Figure 3.
WARNING
TO REDUCE THE RISK OF INJURY
• The water in a spa should never exceed 104°F (40°C). Water temperatures between 100°F (38°C) and 104°F (40°C) 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 100°F (38°C).
• Before entering a spa or hot tub, the user should measure the water temperature with an accurate thermometer since the tolerance of water
temperature-regulating devices varies.
• 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
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 98.6°F (37°C). The symptoms of hyperthermia include dizziness, fainting, drowsiness, lethargy, and
an increase in the internal temperature of the body. The effects of hyperthermia include: 1) unawareness of impending danger; 2) failure to perceive
heat; 3) failure to recognize the need to exit spa; 4) physical inability to exit spa; 5) fetal damage in pregnant women; 6) unconsciousness resulting
in a danger of drowning.
WARNING
RISK OF ELECTRIC SHOCK
Install the power center at least five (5) feet (1.52 m) from the inside wall of the pool and/ or hot tub using non-metallic plumbing. Canadianinstallations
must be at least three (3) meters from the water.
Children should not use spas or hot tubs without adult supervision.
Do not use spas or hot tubs unless all suction guards are installed to prevent body and hair entrapment.
People using medications and/or having an adverse medical history should consult a physician before using a spa or hot tub.
WARNING
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.
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 5 feet (1.52 m) 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.
WARNING
To avoid injury ensure that you use this control system to control only packaged pool/spa heaters which have built- in operating and high limit controls
to limit water temperature for pool/spa applications. This device should not be relied upon as a safety limit control.
WARNING
A terminal bar marked “GROUND” is provided within the power center. To reduce the risk of electrical shock, connect this terminal bar to the
grounding terminal of your electric service or supply panel with a continuous copper conductor having green insulation and one that is equivalent in
size to the circuit conductors supplying this equipment, but no smaller than no. 12 AWG (3.3 mm). In addition, a second wire connector should be
bonded with a no. 8 AWG (4.115mm) copper wire to any metal ladders, water pipes, or other metal within five (5) feet (1.52 m) of the pool, spa, or
hot tub.

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.).
As such, Zodiac Pool Systems LLC does not warrant or guarantee that the chlorinated water generated by the salt water chlorinator 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 or spa.
• For the optimal results, sealers should be reapplied on a regular basis. Reapply the protective sealer on a schedule per the manufacturer’s
instructions.

2.1 Product Description
The salt chlorinator system use a process known as electrolysis to produce sodium hypochlorite (liquid chlorine)
from a low concentration of salt added to the pool water. Hypochlorite kills bacteria, oxidizes organic material,
and kills algae then reverts back to salt. The system then reuses the salt and the process starts over again.

Section 3. Installation Instructions
WARNING
When using electrical products, basic precautions should always be
followed, including the following:
• 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.
• Grounding is required. The unit should be installed by a qualified
service representative and should be properly grounded.
• Install to permit access for servicing.
• Read 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.
3.1 Installation of Power Supply
Always install the power supply of the salt
electrolysis systems VERTICALLY on a solid and
rigid surface (wall) as shown in the recommended
installation diagrams. In order to guarantee a good
state of conservation, the power supply should be
installed in a well-ventilated dry place. Due to IP
degree of the power supply, the salt electrolysis
systems should not be installed outdoors. The power
supply should be installed a bit distant from the
electrolysis cell so that it cannot accidentally suffer
water splashes.
Beware of corrosive atmosphere formation due
to pH decreasing solutions (specially, those ones
based on hydrochloric acid “HCl”). Do not install
the salt electrolysis systems near to any stores
of these chemicals. We strongly recommend the
use of chemicals based on sodium bisulphate or
diluted sulphuric acid.
Power supply must be connected to the electrical
control box of the pool, so that the pump and the
salt electrolysis systems are turned on (and off)
simultaneously.
IMPORTANT
Circuit breaker curve specification should be “D” or “K”.
Figure 3. Power Supply Bracket
3.2 Installation of the Electrolysis Cell
The electrolysis cell is made of polypropylene
in whose interior the electrodes are placed.
Theelectrolysis cell must be always installed
indoors and after the pool filter, and after any other
equipment that may be present (heat pumps, control
systems, etc.).
The installation of the cell should allow easy
access to the installed electrodes by the user.
Theelectrolysis cell should be installed VERTICALLY
in a place of the pipe that can be easily isolated
from the rest of the installation by two valves,
so that the tasks of maintenance can be carried
out with no need of partial or total draining of the
swimmingpool.
Where the cell is installed on a by-pass
(recommended option), a valve to regulate the flow
must be introduced.
Figure 4. Vertical Installation

Page 11
Jandy®Commercial Salt Chlorinator | Installation & Operation Manual ENGLISH
1. Flow direction marked in the cell must be
respected. Recirculation system must guarantee
the minimum flow stated in the Technical
Specifications Table.
Figure 5. Vertical Installation Flow Direction
2. The system flow detector activates if there is no
recirculation (flow) of water through the cell or if
flow is very low, whenever the cell entry valves
are open.
Figure 6. System Flow Sensor Activation
WARNING
A pressure switch or mechanical flow detector palette is
additionally supplied with the unit which provides a redundant
security in absence of water flow through the cell.
The flow detector must be revised periodically as it is a mechanical
element.
3.3 Installing Control/Power Centers
NOTE: The control/power center should be located at or
near the equipment pad.
CAUTION
The control/power center is not to be considered as suitable for use
as service equipment. Therefore, it is required to have the appropriate
means of disconnection, circuit isolation, and/or branch circuit
protection installed upstream of the power center.
Locate the control/power center at least five (5) feet
or more away from pool/spa and five (5) feet off
the ground. All national, state, and local codes are
applicable.
NOTE: For Canadian installations, the control/power
center must be at least three (3) meters (9.8 feet)
away from the pool/spa and 1.5 meters (5 feet)
above the ground.
