THE AUDIBLE ALARM

The alarm sound can be turned down in volume or completely off if required. It may be 

temporarily muted by pressing keypad No. 2, leaving the red warning light flashing and the 

screen message to indicate the warning state. However, the next time the pump turns on it will 

restore the warning sound unless the pool chemistry has been brought back into the normal 

range.

If it is decided to turn off the audible alarm for any reason, the Chemigem will not have 

that warning capability and the pool owners will have to rely on their own ability to 

monitor the indicator lights on the face of the unit to verify that the Chlorine and pH 

levels are within acceptable limits (Refer to pages 14&15)

To lower the volume to half level or turn the sound permanently off, proceed as follows-

ALARM LIGHT AND SOUND - STEPS TO TAKE
Alarms must not be ignored. Immediately investigate the causes and until it is certain 

that the pool water is safe, do not use the pool. Seek professional help from a qualified 

pool maintenance technician if it is not fully understood what is happening.

Read the message on the screen. This will advise which chemical is out of the normal 

• 

range
Make a test of the pool water with a good quality test kit to check if the Chemigem has the 

• 

same readings
It is very important that the chemical reagents in the test kit are well within their use-by 

• 

date. If in doubt, take a fresh sample of pool water to a pool shop for an independent test
If the Chlorine is too low, or the pH too high, check the drums of chemical to determine 

• 

whether they have run out
If the Chlorine is too high or the pH too low, switch off the one that is incorrect and as an 

• 

extra precaution, remove the tube from the drum and place it in a bucket of water

Consult the Problem Solving section on pages 29 to 30 for suggestions on how to deal with 

chemical excesses.
