where the water temperature
is dropping the unit should be operated in Winter Mode as low
temperatures can cause these alarms to operate. For more information read “Water Conductivity”.
Low Temperature Shutdown
Will be Blue if the water temperature falls below 10 - 12ºC (50 - 54°F). Cell Power is tu rned off to
protect the cell. At these temperatures people will not swim and algae cannot reproduce.
The filter can be run to keep the pool clean. When the temperature rises again the
Unit will turn back on automatically.
High Temperature Shutdown LED
Will be Red if the cell water temperature rises to approximately 45ºC (113°F)
This is a safety feature included as the Cell can heat water. In the unl ikely event of the failure of the
pressure switch in a Powered Bypass Installation, the water woul d heat up and could poss ibly boil if
given enough time. When the cell water temperature exceeds approximately 45ºC (113°F), Cell
Power is turned off.
Please note that if the Cell Power has been turned off by any of the fault conditions, an
automated check procedure takes place approximately every 2 hours to see if the fault
conditions have been rectified. The use of RESET will also re -start the system to see if the
fault condition still exists.
WATER CONDUCTIVITY
As the salt level in the pool decreases, the wear on the Cell increases. Although salt is not consumed
in the ECO-matic process, it is lost through splashing, backwashing and on bathers as they leave the
pool. The salt level is also reduced in an outdoor pool by rain, which causes dilution. Salt is not lost to
evaporation. As the salt l evel in the pool falls toward the mi nimum, the LOW CONDUCTIVITY LED
will turn Red. At this point the salt level should be tested and increased to 4,000ppm minimum. (Note
Maximum Salt level should be 5000ppm).
The addition of salt s hould not affect the ECO-matic as it is pr otected against overloads. If no action
is taken and the salt level continues to fall, the LOW CONDUCTIVITY SHUTDOWN will also turn Red
and turn off Cell Power.
The unit will not produce sanitizer in this state
. It will turn ON approximately every 2 hours to
check if salt has been added. If salt has not been added the Cell will turn OFF again:
There are other factors that can cause the Unit to shutdown.
1.
Heavy Rain -
Can cause very dilute pool water to pass over the Cell due to
surface
skimming. The unit will turn back ON after the rain has been mixed into
the water unless the salt
level has been reduced by dilution.
2.
Cold Water
- cold pool water reduces the ability of a Cell to carry electrical
current.
(Refer to
Winter Mode
). More salt can be added if desired.
3.
Failing Cell
- as the Cell ages there will come a time when the electrical current draw will
drop. This can be compensated for with the addition of extra salt. A Cell is considered failed when
it draws less than 80% of maximum current.
