Chemigem Status Indicators, Warnings and Safety Features
Normal Operation – Green Status Indicators
When the Chemigem is operating normally and ORP and pH readings are within the
correct range, a green status indicator will be illuminated and the LCD will indicate the
readings.
Note: it is the pool owner's responsibility to monitor the pool and periodically
confirm the Chemigem readings with a good quality test kit. Remember that the
Chemigem is only able to balance pH and Chlorine levels – but you need to ensure
other factors such as stabiliser levels and total alkalinity are within the correct range
(see page 5 for details).
Low Chlorine
If the ORP falls significantly below the set point, this indicates that the chlorine levels in the
pool have fallen and dangerous pathogens in the water are not being destroyed rapidly.
The Chemigem will warn of low chlorine with a red status indicator and the word "low" will
be displayed on the ORP line (line 3) of the LCD.
Possible causes include:
•
An empty chlorine drum
•
Faulty solenoid valve or dose pump
•
Low levels of stabiliser
•
High pH
•
Filter requires backwashing
•
The multi-electrode (probe) may require cleaning (see page 21 for details)
If each of these factors is addressed, the Chemigem will dose the pool with chlorine until
the set level is achieved – at which point the status indicator will revert to green and the
warning will no longer be displayed on the LCD.
High Chlorine
If the ORP rises significantly above the set point, a red status indicator will be illuminated
and the word "High" will appear on the ORP line (line 3) of the LCD.
Possible causes include:
•
Manual overdosing (superchlorination)
•
Faulty solenoid valve or dose pump
•
The multi-electrode (probe) may require cleaning (see page 22 for details)
•
Low pH (too much pool acid)
•
High Total Dissolved Solids (TDS)
There is no simple way to reduce high chlorine levels quickly. However, chlorine levels will
eventually reduce over days (or weeks), particularly if the pool is exposed to sunlight.
