NOTE: Before installing this product as part of a saline water purification system in a pool or spa using natural stone for
coping or for immediately adjacent patios/decking, a qualified stone installation specialist should be consulted regarding the appropriate type, installation, sealant (if any) and maintenance of stone used around a saline pool with electronic
chlorine generator in your particular location and circumstances.
NOTE: The use of dry acid (sodium bisulfate) to adjust pool pH is discouraged especially in arid regions where pool
water is subject to excessive evaporation and is not commonly diluted with fresh water. Dry acid can cause a buildup
of by-products that can damage your chlorinator cell.

1. Preparing Pool/Spa Water
General Water Chemistry
Salt is required only if you are using the chlorinator features on the Aqua Plus Control. If you are NOT using the
chlorinator, it is recommended that you follow all of the other chemistry recommendations besides salt. Refer to the
description of the Aqua Plus configuration menu for information on enabling/disabling the chlorinator (see page 20).
Water Chemistry
The table below summarizes the levels that are recommended by the Association of Pool and Spa Professionals
(APSP). The only special requirements for the Aqua Plus are the salt level and stabilizer.
Saturation index
The saturation index (Si) relates to the calcium and alkalinity in the water and is an indicator of the pool water “balance”. Your water is properly balanced if the Si is 0 ±0.2. If the Si is below -0.2, the water is corrosive and plaster
pool walls will be dissolved into the water. If the Si is above +0.2, scaling and staining will occur. Use the chart below
to determine the saturation index.
Si = pH + Ti + Ci + Ai - 12.
and total alkalinity. Use the chart above to determine Ti, Ci,and
into the above equation. If Si equals .2 or more, scaling and
staining may occur. If Si equals -.2 or less corrosion or irritation
Measure pool pH, temperature, calcium hardness,
-.2

the pool does not have new water, add metal remover and non-copper based algaecide to the pool, per manufacturer’s
instructions. This ensures a quick, troublefree transfer to the Aqua Plus system.
Salt
Salt Level
Use the chart below to determine how much salt in pounds or (Kgs) should be added to reach the recommended
levels. Use the Pool Sizing Formula on page 4 (measurements are in feet/gallons and meters/liters) if pool size is
unknown.
The operating salt level is between 2700-3400 PPM (parts per million) with 3200 PPM being optimal. Before adding
any salt, test the salt level. This is especially important for retrofit installation to older pools where all of the chlorine
added to the pool over time is ending up as salt. If the level is low, determine the number of gallons in the pool and add
salt according to the chart below. A low salt level will reduce the efficiency of the sanitization and result in low chlorine
production. A high salt level can cause the Aqua Plus to stop chlorinating. The salt in your pool/spa is constantly
recycled and the loss of salt throughout the swimming season should be minimal. This loss is due primarily to the
addition of water because of splashing, backwashing, or draining (because of rain). Salt is not lost due to evaporation.

Type of Salt to Use
It is important to use only sodium chloride (NaCl) salt that is greater than 99.0% pure. This can be found at most pool
stores in 40-80 lb. bags labeled “for use in swimming pools”. Alternatively, use common food quality or water softener
salt that is at least 99.0% pure. It is also acceptable to use water conditioning salt pellets, however, it will take longer
for them to dissolve. Do not use rock salt, or salt with more than 1% of yellow prussiate of soda, salt with anti-caking
additives, or iodized salt.
How to Add Salt
For new plaster pools, wait 10-14 days before adding salt to allow the plaster to cure. Turn the circulating pump on
and add salt directly into the pool. Brush the salt around to speed up the dissolving process—do not allow salt to pile
up on the bottom of the pool. Run the filter pump for 24 hours with the suction coming from the main drain (use pool
vacuum if there is no main drain) to allow the salt to evenly disperse throughout the pool. The salt display may take 24
hours to respond to the change in salt concentration.
Always check stabilizer (cyanuric acid), when checking salt. These levels will most likely decline together. Use the
chart below to determine how much stabilizer must be added to raise the level to 80 ppm.

Aqua Plus Control Center
The Aqua Plus is contained in a raintight enclosure that is suitable for outdoor mounting. The control must be mounted
a minimum of 5 ft. (2 meters) horizontal distance from the pool/spa (or more, if local codes require). The Control
Center is designed to mount vertically on a flat surface with the knockouts facing downward. Because the enclosure
also acts as a heat sink (disperses heat from inside the box), it is important not to block the four sides of the control. Do
not mount the Aqua Plus inside a panel or tightly enclosed area.
When selecting a location, note that the standard cables supplied with the Turbo Cell, flow switch, temperature sensors, and valve actuators (if applicable) are all 15 ft. (5m) long.
Temperature Sensors
Three sensors are included with the Aqua Plus. A water sensor and an air sensor must be installed at all times for
proper operation. A solar sensor is required if the solar function is enabled.
Water Sensor
This sensor is used to measure the pool/spa temperature and is installed in the filtration plumbing after the filter but
before either the solar or conventionally fueled heaters—refer to the plumbing overview diagram.
1. Drill a 3/8” (10mm) diameter hole in the PVC piping and remove all chips and burrs.
2. Insert sensor until O-ring collar sits flush on the hole.
3. Position hose clamp over the sensor and gently tighten until O-ring makes an adequate seal. Do not overtighten.
4. For maximum temperature accuracy, cover the sensor and 3” (6cm) of pipe on either side with insulation and
white paint.
Air Sensor
Mount the air sensor outdoors.
Solar Sensor
For solar applications, mount the sensor near the solar collector array so that it is exposed to the same sunlight as the
collectors. Use additional cable (20 AWG) if necessary.
Chlorination Function
The Aqua Plus includes a Turbo Cell, cell unions and flow switch for use with the chlorinator function. Refer to pages
8 and 17 for plumbing and wiring instructions.
Optional AQL-CHEM ORP and pH Sensing Kit
The AQL-CHEM is an ORP and pH sensing kit for the Aqua Plus. When chlorination is enabled, the Aqua Plus senses
the pool's ORP and pH levels and generates the correct amount of chlorine to keep your pool properly sanitized.
Wiring and plumbing requirements for the AQL-CHEM should be considered before installing the Aqua Plus. Refer to
the AQL-CHEM manual for specific installation information.
Optional AQL-CHEM2 CO2 Dispensing Kit
The AQL-CHEM2 is a CO2 dispensing device that connects directly to the Aqua Plus. When used with an AQLCHEM, the Aqua Plus will sense the pool’s pH level and automatically dispense the correct amount of CO2 to control
the pool’s pH to the desired level. Wiring and plumbing requirements for the AQL-CHEM2 should be considered
before installing the Aqua Plus. Refer to the AQL-CHEM2 manual for specific installation information.
IMPORTANT: Mount the air sensor out of direct sunlight.

Optional Remote Controls
Remote Keypad
push up here
Hayward offers a variety of wired and wireless remote control options for the Aqua Plus. Each model gives you the
ability to control your pool’s functions from a remote location, away from the Control Center.
Wired Remote Controls
Up to 3 wired remote controls can be installed. See page 17 for wiring information.
AQL-WW-P-4
The AQL-WW-P-4 display/keypad must be mounted indoors or in a weather protected area (rain should never touch
the unit). The display/keypad is designed to mount onto a standard electrical utility box (same box as a single light
switch, ideal for new construction) or can be mounted directly onto any wall surface. When selecting a location, note
that the wire to the Aqua Plus main unit must be less than 500’ long. Refer to the remote’s installation instructions as well
as the steps below:
1. Remove display/keypad baseplate from the cover by lifting up on the cover at the lower end of the keypad. See
diagram below.
to remove cover
2. Screw the baseplate in the desired position (screws supplied by installer).
3. See “Electrical Wiring” (page 17) for instructions on running the cable from the Aqua Plus main unit to the
remote display/keypad.
AQL-SS-6B-x (x=W or B for White or Black)
The AQL-SS-6B is a double insulated, waterproof device which is intended for installation at the water's edge. The
remote control comes with an attached 150’ cable and is typically installed at the tile-line of the spa wall, or in the deck,
within arm's reach of a pool/spa occupant. Refer to the AQL-SS-6B installation manual for specific mounting and
wiring information.
Wireless Remote Controls
Note that the Aqua Plus is compatible with AQL2 wireless remote controls only. A single AQL2-BASE-RF Base
Station must be installed on the Aqua Plus in order to use any of the Hayward wireless remote controls. With the Base
Station installed, there is no limit on the number of wireless remotes that can used. The maximum distance between the
wireless remotes and the base station on the Aqua Plus main control unit is 400 feet (120m) line of sight or 200 feet
(60m) through walls, etc. If in doubt about the distance, test operation before installing the remote. All wireless models

Some important notes regarding the Aqua Plus control of Standard Pool/Spa systems:
In Pool/Spa Config., select:
1. The Aqua Plus can be programmed to accommodate spa spillover, if desired.
2. A conventional heater (gas or heat pump) and solar can be used to heat both the pool and the spa.
3. If the chlorinator cell is plumbed prior to the pool/spa return valve, then both the pool and the spa can be
chlorinated
4. The water sensor should be installed prior to any heater or solar and will display either the pool or the spa
temperature, depending on the current operation of the pool. The temperature will only be displayed when the
filter pump is running.
5. If any water feature or pressure side cleaner boost pumps are used, be sure to enable the “interlock” feature
(see “Configuration Menu” for details) to ensure that the pumps operate only when the filter pump is on and the
system is in the “pool only” operating mode.
6. The plumbing diagram above is intended to be used as a general guideline and is not a complete plumbing
schematic for the pool.
7. The air sensor must be installed if the freeze protection feature is enabled for the filter, valves or aux outputs or
if the chlorinator is enabled.
