Cell is completely
clogged from calcium
scale, has failed, or
the cell cord is loose
or damaged.
1. Check cell for calcium scale buildup. Clean as needed.
2. Check for visual wear on the edges of the terminal blades.
3. Check the cell cord for tight connections on the cell and on the power
supply. Check the plug for burns. Tighten or replace as needed.
4. Replace cell if depleted.
Verify cell cables are inserted fully into the AG base cell connector.
The cell cord is
disconnected
Remove and acid wash as described in Maintenance section of manual.
The cell is heavily
scaled.
Verify that the incoming voltage matches the voltage of the Control Unit.
(See Specifications and Installation sections of manual.)
Installer: If the unit is configured for 230-VAC operation, then verify
the input AC voltage is not 115-VAC. Supply correct voltage, or reconfigure
the unit as appropriate.
Cell is not receiving
the expected Amps.
Use the “INFO” button to get cell volts and amps.
• If the volts are 24-26, then the problem is usually caused by low salt,
improperly connected, disconnected or loose cell cord, water less
than 65°F (18.3°C), a scaled cell, or cell near end of life. Correct as
appropriate.
• If the volts are less than 20, then contact Autopilot Systems
for assistance.

Problem
Typical Solution
no FLO

Chlorine generation
has stopped due to
insufficient water
flow.
1. Turn on the circulation pump.
2. Turn the control valves to the correct position to allow water
flow through the manifold.
3. If a suction type vacuum cleaner is used, then clean if clogged.
4. Check and clean the skimmer basket.
5. Check and clean the pump basket.
6. Check and clean or backwash the main circulation filter.
7. Clean the manifold screen of trash or debris. For instructions to clean
the screen, test the flow switch, see Maintenance section of manual.
8. Clean the SuperCell if plugged with debris or calcium scale (See
Maintenance section of manual.)
9. Check for leak at pump basket O-ring, leaking valve or fitting.
10. If the pump is a 2-speed pump, is it on low speed? The low speed
may not create enough flow for the manifold.

Cell has been
removed from the
pool for swimming.
When 75092 cell is returned to the pool, cycle power and normal operation
should commence. If power is not cycled, up to 15 minutes may be
required for normal operation.
