Section 1. Safety Information
IMPORTANT SAFETY INSTRUCTIONS PERTAINING TO A RISK OF FIRE,
ELECTRIC SHOCK, OR INJURY TO PERSONS
READ AND FOLLOW ALL INSTRUCTIONS
When installing and using this electrical equipment, basic safety precautions should always be followed,
including the following:
WARNING
To reduce the risk of injury, do not permit children to use this product unless they are closely
supervised at all times.
WARNING
When mixing acid with water, ALWAYS ADD ACID TO WATER. NEVER ADD WATER TO ACID.
WARNING
To reduce the risk of electric shock, fi re or injury, service should only be attempted by a qualifi ed Pool
Service Professional.
WARNING
Do not operate electrolytic cell without proper fl ow or water circulation. A buildup of fl ammable gases
would result in hazardous conditions.
WARNING
Installation must be done in accordance with the National Electric Code (NEC, NFPA-70) and/or any
other applicable local and national installation codes.
RISK OF ELECTRIC SHOCK, FIRE, PERSONAL INJURY, OR DEATH. Connect only to a circuit
that is protected by a ground-fault circuit-interrupter (GFCI). 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, there is ground current fl owing, indicating the possibility of an electric shock. Do not
use this unit. Disconnect this unit and contact a qualifi ed service representative before using.
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 ensures 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.
It is recommended that the water Flow/Temp/Salinity Sensor is installed in the same piping as the
electrolytic cell, without any valves or diverters between them. (See page 5 Figure 1).
The Flow/Temp/Salinity Sensor must be mounted as shown on page 12 Figure 8.
Page 5
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, Jandy Pool Products, Inc. does not warrant or guarantee that the chlorinated water generated
by the AquaPure 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 purifi cation 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
.

Figure 1. Typical AquaPure Installation With Options
A TTENTION INST ALLER: Various application notes (more detailed instructions) are
available from the Dealer covering installation, operation, maintenance, and plumbing
of the chlorinator system.
The AquaPure 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 AquaPure then reuses the salt and the process starts over again.
The AquaPure system is comprised of the following three component parts and an optional pool pump timer.
Control Center The control center converts AC electrical current to a low voltage DC current which
is required by the cell to perform the electrolysis. The control center is connected
with the pool circulation pump electrical source so that the electrolytic cell only
operates when the pool pump is on. The fl ow portion of the Flow/Temp/Salinity
Sensor
Electrolytic Cell The AquaPure electrolytic cell contains bipolar electrodes which perform the
is a backup device only.
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 AquaPure is on each day. The
AquaPure automatically cleans the Cell electrodes once every 3 hours by reversing
polarity. This does not interrupt the production of Chlorine.
Page 7
Flow/Temperature/Salinity Sensor The Flow/Temp/Salinity Sensor only allows the Cell to operate if
there is adequate water fl 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.

3.2.2 Recommended Plumbing Confi guration
The preferred installation is that the Cell and Sensors are plumbed in the return line to the pool after
(downstream of) all the pool equipment (fi lter, heater, solar, etc.). The Cell and Sensor fi tting are designed
to be plumbed into 2” PVC pipe. Adapters can be used for systems with 1½” plumbing. Figure 3 shows
cell and sensor confi guration with fl ow direction. Figures 4 and 5 illustrates the recommended plumbing
confi gurations, which result in the most reliable operation.
Note The AquaPure is powered from the LOAD SIDE of the pool circulation pump relay or the time clock. This
ensures that the Cell only operates when the pool pump is ON. The Flow Sensor serves as a protection
device to ensure there is suffi cient fl ow for the Cell to operate.

3.3 Installing APURE700 and APURE1400 Control Center
1. Locate the control center as close to the pump and fi ltration system as possible. Make sure that the DC
power cord and the Flow/Temp/Salinity Sensor cable can reach that section of pipe selected for the Cell
and Flow/Temp/Salinity Sensor installation. Do not install the Control Center within 10 ft (3 m) of the
pool edges.
2. Use hardware provided and mount the control center at eye level. Leave suffi cient clearance on all
sides of the chassis backplate. If possible, leave a minimum of 9½ inch (241 mm) on the left side.
Position the backplate on the mounting surface. Mark screw centers and drill four ¼ inch (6.35 mm)
holes spaced 10

6. Check source voltage. (All units are factory wired for 240 VAC). In order to use on 120 VAC, the
internal factory wiring of the control center must be changed. (See wiring diagram page 6
Figure 2).
7. Use #12/3 insulated wire and conduit. Wire control center transformer to pool pump power source.
The control center should be connected to the pump motor switch or automatic timer (Pool Pump
Timer) as shown in the diagram on page 6 Figure 2. The fl ow portion of the Flow/Temp/Salinity
Sensor is a backup device only. Attach the third wire (Ground) from the electrical panel to the ground
point inside the Control Center. Earth bonding in Section 3.4 must also be accomplished to ensure
personal safety and safety of equipment.
3.4 Earth Bonding (Grounding)
2
A solid, copper # 8 AWG (8.4 mm
) wire is recommended for connecting the control center to a Permanent
Earth Ground connection that is acceptable to the local inspection authority. Refer to your local codes for
the acceptable grounding wire gauge. Attach the bonding point located on bottom of the chassis backplate
to a Common Earth Bonding Point. Do not use the AquaPure as the Common Bonding Point. Each piece
of non-AquaPure related pool equipment requiring a ground should be bonded to the Common, Approved
Earth Bonding Point. Never ground pool pump to the chassis backplate.
3.5 Installing the APURE700 and APURE1400 Cell and Flow/Temp/Salinity Sensor
NOTE: Maximum Operating Pressure is 345 kPa or 50 PSI - Minimum Flow Rate is 30 GPM (114 LPM).
1. Be sure pool pump is turned off.
WARNING
ATTENTION INSTALLER: If The Flow/Temp/Salinity Sensor is not installed properly, it may allow the
Cell to operate without water fl ow. This would cause a buildup of fl ammable gases which can result
in FIRE or EXPLOSION.
• Mount as shown in Figure 8. This will result in the most reliable operation.
• The Flow/Temp/Salinity Sensor must be mounted:
(1) in the same line as the Electrolytic Cell.
(2) with no valves or diverters between the Flow/Temp/Salinity Sensor and Cell.
• Anytime the Flow/Temp/Salinity Sensor is connected or disconnected and reconnected, the AC
power to the unit must be turned off and back on (Cycle Power). If power is not cycled, unreliable
operation of the Flow/Temp/Salinity Sensor will result.
2. It is recommended that the Flow/Temp/Salinity Sensor and Electrolytic Cell be installed in the pool
return line after the fi lter and heater. The Cell can be installed in either a horizontal (as shown in
Figure 3) or a vertical position.
3. Position the Flow/Temp/Salinity Sensor and Cell in the recommended position (see page 8 Figure 3,
page 9 Figures 4 and 5, and page 5 Figure 1).
4. Locate a suitable section of pipe, approximately 17 inches (432 mm) long or follow the recommended
plumbing diagrams beginning on page 9, Figures 4 and 5. The Flow/Temp/Salinity Sensor cable and
Cell DC cord must be able to reach from the control center to this section.
