Problem

There are no warning messages on the display but the chlorine level is too low. Water quality
looks dirty or cloudy.

Typical Solution

1. The chlorine setting has been fine, but a temporary boost of chlorine is needed to adjust for heavy rain

or a temporary bather increase. Press the BOOST button to temporarily elevate the chlorine
production level to 100% for 24 hrs. Press and hold the BOOST button for 8 seconds if a 72 hour
BOOST cycle is desired. The chlorine output will revert to the original setting after 24 hrs.

2. Check water balance. See "Water Balance and Chemistry Recommendations" on page 5. The

Cyanuric acid level may be low and the chlorine is being consumed quickly by the UV from the sun.

3. The purifier output needs to be increased.

Use the UP arrow key to increase the purifier output setting. Push SELECT to save the change.

Increase the pump run time so the Pool Pilot

is generating chlorine for a longer period of time.

(Systems are typically sized for a minimum 8 hr. pump run time.)

4. Consult your local pool service professional and test for high phosphate levels. Use a product such as

Lo-Chlor® Lo-Phos® to reduce phosphates.

5. If the water temperature is 55 °F (10 °C) or colder, the Pool Pilot

has automatically turned the Purifier

output down to 1% to avoid over-chlorination. Bacteria and algae activity is greatly reduced at these
temperatures, so this should not be a problem. Hand dose additional chlorine if necessary.

6. Obtain an independent salt reading to check the Pool Pilot

reading. Add salt, if needed, and re-

calibrate the Pool Pilot

salt display.

7. Check the “Max temp” in the Setup Menu. If higher than the Shutoff temperature, unit may be going

into a cooling mode. Shade, or relocate unit to an area less affected by direct sunlight or other sources
of heat external to the unit.

8. Possible Pool Pilot

fault.

Press BOOST. Wait 10 seconds for the unit to start the Boost cycle.

Press MENU. Select “Test Pool Pilot”; record the Volts and Amps when displayed. If the Volts
are less than 4.0 and the Amps are less than 1.5, contact the factory for assistance.

Problem

There are no warning messages on the display. The chlorine level is too low but the pool water
looks fine.

Typical Solution

The test kit reagents or strips may be old or have been exposed to sunlight. Replace the kit or
reagents and retest.

There may be too much chlorine in the pool. The chlorine is bleaching the test kit reagents.

Dilute the water sample with distilled water and retest. Lower the chlorine output setting with the DOWN
arrow button if the chlorine level is too high.

Problem

Chlorine % fluctuates from adjusted value.

Typical Solution

The AutoPilot

unit has a patented process for automatically increasing and reducing the

chlorine output as the temperature of the water fluctuates. It is normal for the % output to
increase as the water temperature increases, and to decrease as the water temperature
decreases.
