Section 1. Important Safety Instructions
READ AND FOLLOW ALL INSTRUCTIONS
LIRE LA NOTICE TECHNIQUE.
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 ttings of your spa or hot tub. Never operate a spa or hot
tub if the suction ttings are broken or missing. Never replace a suction tting with one rated less than the ow rate
marked on the equipment assembly.
WARNING
To Reduce the Risk of Injury -
a) 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.
b) 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).
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.
d) The use of alcohol, drugs, or medication before or during spa or hot tub use may lead to unconsciousness with
the possibility of drowning.
e) 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.
f) 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. 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 ve (5) feet (152.4cm) from the inside wall of the pool

The PureLink Power Center and Cell Kit uses 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 PureLink then reuses the
salt and the process starts over again. The PureLink system is comprised of the following three component
parts.
Power Center The AquaLink RS PureLink Power Center converts AC electrical current to a low
voltage DC current which is required by the cell to perform the electrolysis. The
power center is connected with the pool circulation pump electrical source so that
theelectrolyticcellonlyoperateswhenthepoolpumpison.Theowportionofthe
Flow/Temp/Salinity Sensor is a backup device only.

Page 8
Electrolytic Cell The PureLink electrolytic cell contains bipolar electrodes which perform the
electrolysis and produce chlorine when energized with DC current. Chlorine
is generated as pool water containing salt passes through the cell. The chlorine
production can be varied by either adjusting the Chlorine Production Level on the
power center or by varying the number of hours the PureLink is on each day. The
PureLink automatically cleans the Cell electrodes once every 3 hours by reversing
polarity. This does not interrupt the production of Chlorine.
Flow/Salinity/Temperature Sensor The Flow/Temp/Salinity Sensor only allows the Cell to operate if
thereisadequatewaterowthroughtheCell.ThesalinityportionoftheFlow/Temp/
Salinity Sensor detects the level of salt in the pool water. This salt level is displayed
in grams per liter (gpl) on the Liquid Crystal Display (LCD) whenever the salinity
button is pressed. This eliminates the need for manual pool water salinity testing.
Pool Temperature is now available on all models by pressing the Temperature button.

3.6 Connection to the AquaLink®RS PureLink Control System
The Jandy AquaLink RS PureLink is a multi-function pool controller and can fully control the function of
the AquaPure chlorine generator. The AquaPure will display JA when a button is pressed at the AquaPure
while the Jandy AquaLink RS PureLink is in control. Adjustment of the AquaPure chlorine production rate
can be controlled from the main menu of the AquaLink RS Controller (All Button, OneTouch, or PDA).
Boost mode may be activated from the AquaPure while the AquaLink RS is online. Refer to the
AquaLink RS Operation Manual (or AquaLink RS PDA Operation Manual) for more information. The
AquaPure temperature, salinity, service codes, and LED indicators operate as normal.
NOTE The AquaPure Chlorine Generator will communicate with AquaLink RS using rmware versions JJ or later.

Section 4. Pool Water Preparation
4.1 Determining Pool Size (m3of Water in Your Pool)
•Rectangular Pools
Average length (meters) x average width (meters) x average depth (meters) = m3capacity.
• Circular Pools
Diameter (meters) x diameter (meters) x average depth (meters) x 0.79 = m3capacity.
• Oval Pools
Long diameter (meters) x short diameter (meters) x average depth (meters) x 0.79 = m3capacity.
• Sloping Sides
Multiply total m3by 0.85 = m3capacity.
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.
