Cell and Manifold Installation
Your Pool Pilot System is adaptable for use with either the SC-36, SC-48 or SC-60 cell. All models come pre-assembled with
a Patented Automatic Flow Bypass Manifold Assembly. The manifold must be located as the last accessory in the POOL
RETURN LINE only. For pool/spa combinations or special plumbing configurations, please contact the factory for assistance
in locating the manifold.
Standard Manifold Assembly (all models):
WARNING: Do not mount the manifold upside down.
Maximum flow rate 100 gpm (22.6 m³/hr). We recommend using a 2 lb spring bypass check valve for flow rates greater than
100 gpm (22.6 m³/hr) and plumbing it parallel to the manifold.
To Pool Return
*One set of 68mm x 2” metric adapters (#19059) included with European Systems.
For other plumbing configurations, please contact the factory for assistance.
Verification of Flow Switch Protection:
It is important to annually inspect and verify the safe and proper operation of the Tri-sensor’s Flow Switch protection device.
Autopilot recommends following this procedure to verify that the flow switch is working as designed, which is to halt power
from being sent to the cell in the presence of insufficient flow. A defective Flow Switch can cause serious equipment damage.
Using either a GOLF BALL or small plastic wrap (saran wrap, food wrap or zip lock bag), block off flow to the upper portion
of the manifold by placing the golf ball in the strainer screen union or by wrapping the strainer screen with the plastic wrap and
placing it back in the union and tightening. Operating the system on with this blockage should detect a FLOW obstruction,
turning the FLOW-OK light off and activating a single red SERVICE flashing light. Once this protection feature has been
verified, remove the plastic wrap or golf ball, replace the strainer screen and resume operation. Turn the output dial to OFF
and contact the factory if the flow switch protection does not activate properly.

The Pool Pilot™ Soft Touch Purifying LOW NORMAL
OUTPUT level is adjustable from 0% (OFF) LONG
to 100 %(MAX). Press the Up/Down Arrows 0% ADD
to set the desired output level. Little adjustment Concealed Set Up Button
is needed once the initial setting is established. The selected output level will remain
steady when the system is at rest and will begin pulsing when the system is producing the purifying agent.
Note: The Pool Pilot™ Soft Touch does not test for purifier levels nor automatically adjust to maintain a desired
purifier level. This is done by periodically testing the water and adjusting the output levels up or down, as needed.
The Pool Pilot Soft Touch is designed with an AUTOMATIC TEMPERATURE COMPENSATION feature, which
automatically adjusts the output level setting based upon changes in seasonal water temperatures only. This unique feature
conveniently compensates for warm (more purifier needed) or cold (less purifier needed) water conditions.
The SETUP Mode allows the user to program the CELL POWER and REVERSING cycle. To enter Setup Mode, press and
hold the concealed Setup button (small bubble adjacent to the Salt OK light) until the CELL POWER light begins flashing.
The Pool Pilot ™ Soft Touch is set on “ 2 “ from the factory. Use the Up/Down Arrows to change the Cell Power setting if
needed. Adjust the OUTPUT level at the new setting to maintain proper sanitizer levels.
WARNING: Operating on “ 1 “ reduces cell power but extends cell life; “ 3 “ increases cell power but reduces cell life.
Pressing the Setup Button once more will go to the REVERSING cycle. The Pool Pilot™ Soft Touch is set on “NORMAL”
from the factory for ideal cell life. Use the Up/Down Arrows to select the Reversing cycle. For conditions such as extremely
high calcium levels or conditions that can cause the cell to scale quicker than the self-cleaning cycle can control, change the
setting to “SHORT”. For optimum water chemistry balance according to the Saturation Index, see page 9, you can change the
REVERSING cycle to “LONG ”. Pressing the setup button once more will leave the Setup Mode and save the programmed
Cell Power and Reversing settings. Test your water chemistry parameters m onthly and compare to the Saturation Index.
WARNING : Changing the Reversing cycle to SHORT will also reduce cell life. However, operating the cell under scaled
conditions on “Normal” or “Long” is more detrimental to the life of the cell and changing the Reverse cycle is suggested.
The BOOST Button activates the Boost light when it is pressed once. This light indicates that the system is in Boost Mode
and will produce the purifying agent for 24 hours. The purifying agent can be produced for 72-hours by pressing and holding
the BOOST button for 5-seconds from the Boost -Off position. This is called the Super-Boost Mode. A flashing Boost light
indicates that the system has successfully entered this mode. In either mode, the purifying agent is produced continuously,
throughout the normal On/Off cycles of the pump and throughout all power line disturbances at an output purifying level of
100% regardless of the normal purifying output level setting. The system will discontinue operation of the Boost mode or
Super Boost mode if the boost button is pressed once more and return to the normal purifying output level setting.
The SALT light indicates the salt level in the water. The salt level should be maintained between 2500 – 3500 ppm (2,5 – 3,5
g/l). The SALT-OK light will be on if this salt level is achieved. If the salt level drops below 2500 ppm (2,5 g/l), the SALTLOW light will turn on and the system will continue to produce the purifying agent. If the salt level drops below a safe value,
the SALT-ADD light will turn on and the system will no longer continue to produce the purifying agent. The Pool Pilot ™
Soft Touch can also handle special application salt levels of up to 35,000 ppm (35,0 g/l) without any adverse effects to the unit.
(NOTE: HIGH Salt level does not affect purifier production but can cause corrosion problems with metallic fixtures, light
rings, ladders and hand rails.) See Appendix (page 14) to determine your salt level.
The FLOW-OK light turns on when there is sufficient flow. Any problems with insufficient water flow is indicated by a
Flow-OK light that is not on and a Flashing Service Light (single flash pattern).
The SERVICE light flashes when service is needed. A Single flash pattern of the service light indicates insufficient water
Flow. A Double flash pattern of the service light indicates high cell volts and low amps, which is caused by a scaled or failing
cell or a loose/defective cell cord. A Triple flash pattern of the service light indicates high cell volts and low amps, which is
caused by a failed power supply. A Quadruple flash pattern of the service light indicates a failed tri-sensor or cord.

Section 3b – OPERATION
Pool Water Preparation
Salt Requirements
It is important that with typical pools, a salt residual of 2500 to 3500 ppm (2,5 – 3,5 g/l) be maintained at all times for peak
efficiency. The Pool Pilot ™ Soft Touch can also handle special application salt levels of up to 35,000 ppm (35,0 g/l) without
any adverse effects to the unit.
NOTE: HIGH Salt level does not affect purifier production but can cause corrosion problems with metallic fixtures, light
rings, ladders and handrails.
The amount of salt required depends on the size of the pool and the present salt level. As the salt is being added, we
recommend running the circulation pump continually for 24 hours with the main drain opened. Brushing the salt towards the
bottom main drain will assist in the dissolve rate and prevent possible staining with certain types of salt.
We recommend the use of AutoSoft Plus™ Water Conditioning Salt. AutoSoft Plus™ salt contains 99.8% pure Sodium
Chloride (NaCl) without Iodine or the Anti -Caking additive, Yellow Prussiate of Soda (YPS). Iodine and YPS can cause a
localized tint to the water or yellow staining on the cementitious finish if allowed to rest undissolved on the finish for extended
periods of time. AutoSoft Plus™ is blended with the proper amount of stabilizer to maintain a proper level within the
recommended range when added according to the salt chart on the box.
Granular Salt, Table Salt, Solar Salt or Water Conditioner Pellets can also be used but will have different dissolve rates. If the
salt you use contains Iodine or YPS, constant brushing will help the dissolve rate and prevent staining due to the additives in
the salt. Ensure that the salt you use contain a minimum purity of 99% Sodium Chloride (NaCl).
NOTE: Do not use Rock Salt due to its high levels of impurities.

Start Up Procedures
Keep the Output Setting on your Pool Pilot ™ Soft Touch on 0% (OFF) until you get your water clear, blue and properly
balanced.
1. After balancing your water chemistry according to the Water Chemistry Parameters shown on page 9, add the proper
amount of salt (see Salt Requirement Chart above) and circulate 24-hours prior to starting your Pool Pilot™ Soft Touch.
2. The following day, turn your Output Level to 50% and operate normally. For the first two weeks, test the water every 2-3
days for proper Purifier levels. Raise or Lower the Output Control Setting as needed, according to your test results.
3. Once your Output Level has been established, you will only need to adjust your level according to increased bather usage.

Section 3c – OPERATION
Monitoring and Maintenance
Water Chemistry Parameters - VERY IMPORTANT NOTE! Your Pool Pilot ™ Soft Touch is designed to provide
Purifier on a daily basis. We recommend the following water chemistry ranges and periodic checks to monitor your systems
efficiency. Always follow all local and state requirements.
Biweekly Checks: Monthly Checks:
Free Chlorine: 1.0 – 3.0 PPM Calcium Hardness: 200 – 400 PPM Salt Residual: 2500 – 3500 PPM
Or Bromine: 2.0 – 4.0 PPM Total Alkalinity: 80 – 150 PPM Saturation Index: ± 0.3 pH of saturation
pH: 7.2 – 7.8 Cyanuric Acid: 60 – 80 PPM Visual Cell Inspection for wear, scale or debris
CHLORINE/BROMINE REQUIREMENTS: During Peak Purifier Demand (rainy season or heavy bather usage) it may be
necessary to increase your purifier level by increasing your Output Level setting and/or pump run time. Conversely, during
Low Purifier Demand, you can decrease your Output Level to a lower setting. For extremely Heavy Purifier Demand or to
boost your purifier levels quickly, you can Boost the system or supplement with a Potassium Monopersulfate based shock. If
the water is clear but is difficult getting a bromine residual using DPD or test strips, we recommend using an OTO test kit.
NOTE: During cold-water conditions, below 60ºF, Purifier demand is reduced significantly. For colder climate regions
with sust ained low or freezing temperatures, contact your local pool professional for proper pool winterizing instructions.
WARNING: Excessive chlorine levels can cause corrosion damage to stainless steel rails, ladders, heater heat exchangers,
light faceplates and other metallic equipment. Avoid over saturation of chlorine levels.
pH: When pH levels fall below the recommended range, Purifier is used up quickly and can be damaging to equipment. For
pH levels higher than the recommended range, Purifier becomes less effective and works harder to keep your pool purified.
Improper pH also contributes to the strong smell, red eyes, dry itchy skin and brittle hair conditions associated with “too much
Chlorine”.
CALCIUM HARDNESS AND TOTAL ALKALINITY: Your Pool Pilot ™ Soft Touch provides 100% pure sodium
hypochlorite and does not affect the calcium hardness or total alkalinity levels. Maintain and balance only as needed.
CYANURIC ACID (STABILIZER/CONDITIONER): This chemical goes by either trade name and allows the chl orine
residual to last longer by protecting it from the UV degradation of the sun. With low or no Cyanuric acid it is possible for the
chlorine to be used up as quickly as it enters the pool. Check and maintain your cyanuric acid levels at the same time as your
salt level, as these tend to deplete at the same rate.
NOTE: For Bromine or indoor pools, it is not necessary to add stabilizer.
SALT RESIDUAL: Your Pool Pilot ™ Soft Touch works most efficiently with salt levels between 2500- 3500 ppm (2,5 – 3,5
g/l). If it falls below 2500 ppm (2,5 g/l), determine the salt level and adjust according to the SALT REQUIREMENT. Low
salt will cause premature deterioration of the Cell blades. For “SEAWATER” pools, your Pool Pilot ™ Soft Touch is designed
to handle up to 35,000 ppm (35,0 g/l), however, salt levels above 6000 ppm (6,0 g/l) can be corrosive to metallic fixtures.
BROMINE RESIDUAL: Along with the normal Salt level, add 1lb (0.45 kg) Sodium Bromide (NaBr) per 2000 gallons (0.75
m³) of water. Your Pool Pilot ™ Soft Touch will now generate Bromine to purify your pool. Maintain your bromine level by
checking your salt level. Once your salt falls below the recommended range, we suggest you add 1lb (0.45 kg) sodium
bromide with every 50 lbs (22.5 kg) of salt added. We recommend testing Bromine Purifier levels with an OTO test kit.
SATURATION INDEX (Si): a formula used to ensure that your total water chemistry does not fall into a scale forming or
corrosive condition. Either condition can cause premature damage to the Cell, equipment and cementitious finish. Have your
water professionally tested periodically according to the Saturation Index or use this chart to determine your water balance.

TRI-SENSOR ASSEMBLY
The Tri-sensor assembly tests for Flow, Salt and Water temperatures. A minimum flow rate of 15 gpm (3.4 m³/hr) is required
to activate the flow switch. As the water flow closes the paddle, a magnet activates a micro switch to verify proper flow. The
Salt sensor protects against low salt levels and the temperature sensor protects against cold water temperatures. Both of which
can contribute to accelerated cell failure.
? Note: The use of high strength magnet devices in the close proximity
of the tri-sensor can cause the flow switch to read incorrectly.
Remove the Tri-Sensor as follows (with pump off):
Remove both screws from the sides of the Tee Assembly.
With the aid of large Channel -lok® (or similar) pliers, firmly
grip the Tri-Sensor assembly and move back and forth
while removing the Tri-Sensor from the tee. directional

Cell
The Cell is installed with Unions on each end of the cell to allow quick and easy removal. Loosen the unions and remove the
cell from the plumbing.

VISUAL CELL INSPECTION:
The titanium Cell blades, seen inside the Cell body, should be straight and clear of any debris between the blades. Your Pool
Pilot™ Soft Touch is designed to automatically self-clean calcium scale build-up within the Cell. However, imbalanced water
chemistry and certain conditions can cause a heavier scale build up that exceeds the self-cleaning capability and would need to
be cleaned manually by the method described below.
Periodically inspect both ends of the cell.
A White Flaky or Crusty build-up on the
edge or between the blades will prematurely
deplete the life of the cell. Immediately End View of cell

scaling. See Troubleshooting Section, page 13.
MANUAL CELL CLEANING :
With the Cell removed as described above, use a high-pressure hose nozzle to spray off as much loose scale and debris as
possible. Any remaining calcium scale can be treated with a mixture of one (1) part Muriatic Acid into four (4) parts water.
Mix the solution in a container high enough to cover the Cell blades.
Remove the Cell cord and immerse the Cell so that the blades are compl etely covered in the solution for up to 15 minutes. An
effervescences action indicates the calcium is being neutralized and cleaned. Drain the cell, flush with fresh water and reinspect. Repeat the immersion if necessary.
We recommend using Lo-Chlor Sa lt Cell Protector Plus as a prevention additive to continually help soften and reduce build-
up of calcium scale deposits in the cell. This product also reduces calcium scale on exposed aggregate finishes and new pool
finishes and enhances chlorine production.
DANGER: ALWAYS ADD ACID TO WATER, never water to acid.
NEVER USE ANY SHARP OR METALLIC OBJECTS TO REMOVE SCALE. Scraping or scratching the titanium
blade’s edge or surface will allow chemical attack of the blade, cause premature failure of the Cell and will void your
warranty.

FILTER BACKWASHING:
We recommend turning the Control Panel Output setting to 0% (OFF) when backwashing a Sand or DE filter.

Appendix – BUILT -IN DIAGNOSTICS
BUILT-IN DIAGNOSTICS
The Pool Pilot ™ Soft Touch Control Box contains a way to display a diagnostic report on its operation. It allows the user to
view the salt concentration, the water temperature, and the Electrolytic Cell voltage and amperage. This is provided for a
technician to evaluate the performance of the Pool Pilot without the need for special equipment. The values are measured by
counting the number of flashes of the lights, as described below.
To access and interpret the diagnostics, follow this procedure:
To start the diagnostic procedure, press and hold both the UP and DOWN buttons at the same time. Hold them pressed
until the output display lights go out, leaving just the bottom light illuminated (about 5 seconds).
1. The first value to be displayed is the salt concentration in Parts Per Million (PPM). This value is measured by
counting the number of flashes of the top 3 lights. In the case of salt, the top light is not used, the next to the top
flashes the 1000’s digit and the third light flashes the 100’s digit in ppm.
Example: 2 flashes/pause/8 flashes/pause Read: 2,800 PPM
2. The second value is the water temperature in degrees Fahrenheit. When this is displayed, the second light from the
bottom is on. The top light flashes the 100’s digit, the next the 10’s digit and the next the units of temperature.
Example: 8 flashes/pause/6 flashes/pause Read: 86 Degrees F
3. When the third light from the bottom is on, the cell voltage is displayed. The top light is not used. The second light
flashes the 10’s digit and the third the units of voltage.
Example: 2 flashes/pause/8 flashes/pause Read: 28 Volts
4. When the fourth light is on the cell current in amperes is being displayed. The top light displays the 10’s digit (not
normally used), the next the units and the third the tenths of amps.
Example: 5 flashes/pause/5 flashes/pause Read: 5.5 Amps
