Maintenance - Autopilot Pool Pilot PROA Series Owner's Manual

®
AutoPilot PRO WC systems are designed to operate 24 hours a day and 7 days a week at
maximum production rates and will give you years of trouble-free use if you follow these basic
maintenance and cleaning instructions.
This system produces sodium hypochlorite "liquid chlorine" from the salt that you have added
to the water. It will only continue to operate correctly if salt is maintained at a minimum
3,500ppm level. Low salt will lower the amount of chlorine produced, and cause damage to the
electrolytic cell. When maintained properly the electrolytic cell has a life of 15,000 hours.
(Warranties will not be honored if it is determined that salt has been run low.)
The titanium plates that make up the cell will last 15,000 hours or more if properly maintained.
By ensuring that salt is always at the correct level, and plates are cleaned regularly, you will
ensure 15,000 hours of operation or more.
Check salt concentration. Salt must be maintained at 3,500 to 5000 ppm. Check salt as
often as necessary to ensure the concentration.
Adjust the salt concentration as often as needed to maintain the desired level.
Test the flow switch for proper operation at least once a month and clean the strainer as
often as needed.
WARNING: Failure to heed the following may result in injury or death.
•
EXPLOSION RISK: - Never operate the system with a bypassed or defective
flow switch.
To test the flow switch, close the lower cell isolation valve stopping flow to the cell.
Immediately check to see if the system shut off. If the system does not shut off, immediately
open the valve. Do not allow the system to operate with the valve closed. Replace a
defective flow switch immediately.
To clean the strainer, disconnect power from the system, close the lower cell isolation valve
and then close the upper cell isolation valve. Unscrew the strainer cover. Allow pressure to
release slowly. Remove the strainer screen, clean the screen and reinstall.
Evaluate the cell condition every week
Visually inspect the cell tube for leaks and the cell stack for calcium build up. Check the
connections at the top of cell and clean as needed.
