Operation of the ECO-matic System
The electrolytic Cell Output is shown on a PRODUCTION meter made up of a bar of five LEDs on the left-hand side of
the control panel. Normal cell operation is indicated by five green LEDs being on.
The Unit is fitted with an electronic control and warning system. This regulates the output of the Unit to a preset
maximum. The warning system consists of an OPERATION LED which will glow Red to indicate possible faults with the
Unit or damaging operating conditions.
Once the salt level in the pool is correct the Unit may be switched ON. The OPERATION LED will be Green and no Cell
Output will be seen for approx. 60 seconds, this allows the pump and filter to prime and the Cell Housing to fill with water.
After this start-up delay, the bar meter should light up showing all five LEDs. At this point the WARNING LED should be
Green; if it is Red it indicates that there is a problem and please refer to the table below.
Production Bar Meter Operation LED Reason / Action
Off Green
1. Start – up delay functioning.
2. System Control dial set below MAX. Cell is turned off.
(Refer System Control page 12).
5 LEDs Green System operating normally
Less than 5 LEDs Green
1. Salt level is too low. Add a rate of 8.5 lbs per 1,000 gallons
until recommended salt level reached.
2. Cell is calcified. Clean cell.
3. Water temperature low. Add salt to compensate
Less than 5 LEDs Red
1. Salt level is very low. Add a rate of 8.5 lbs per 1,000 gallons
until recommended salt level reached.
2. Cell is calcified. Clean cell.
3. Water temperature low (<77ºF). Add salt to compensate
Off Red
1. Gas detected. Check pump/pipes for damage or blockage.
2. Gas sensor not connected to cell
