!!!Warning!!! No flow
Problem
Chlorine generation has stopped due to insufficient water flow.
Typical Solution
1.
Turn on the circulation pump.
2.
Turn the control valves to the correct position to allow water flow through the manifold.
3.
Check and clean the skimmer basket.
4.
Check and clean the pump basket.
5.
Check and clean (or backwash) the main circulation filter.
6.
Clean the AutoPilot
®
manifold screen of trash or debris. For instructions to clean the screen, test the
flow switch, and clean the bypass valve, refer to the "Maintenance" section of this manual. See "Test
Tri-sensor Flow Switch" on page 12.
7.
Verify that the Tri-sensor cable is plugged in. When plugging in, use care to orient correctly before
inserting into the unit.
8.
Clean the cell if clogged with debris or calcium scale.
9.
Check for air in the bypass manifold by loosening the top union on the cell to see if air or water comes
out. If air comes out then there may be a vacuum side leak or the pump may be undersized. Check for
a leak at the pump basket o-ring, a leaking valve or fitting.
10.
If the pump is a variable speed pump, ensure there is sufficient flow to the manifold (or Tri-sensor if a
convection cell system) to activate the flow switch? The low speed may not create enough flow for the
manifold.
Warning: Low Salt / Add xxx lb
Problem
The salt level is below 2,500 ppm (mg/L) (which is low).
Typical Solution
This message will appear when salt is at 2,400 ppm (mg/L), or below. Add salt as indicated on
the Pool Pilot
®
display to bring the salt level up to 3,000 ppm (mg/L).
If message still appears, confirm salt level with a tester. If salt level is sufficient and error
message still appears, contact your local AutoPilot
®
Service Center. There may be a problem
with the Tri-sensor or cell cord.
Warning! Bad temp sensor?
Problem
The Tri-sensor may be damaged. The unit will default to 75°F and continue to operate, but
without the Automatic Temperature Compensation feature.
Typical Solution
Check the Tri-sensor cable; make sure it is not loose or disconnected.
If error message remains, check the water temperature using a thermometer. Record results and
contact your local AutoPilot
®
service center for assistance.
