Safety 

 

2.1

 

Intended use 

The IQntrol DOS MODBUS device is designed for carrying out measuring and control tasks when treating swimming pool water in 
private swimming pools. 

 

 

2.2

 

Safety notices 

The operation manual must be consulted prior to installation, commissioning and maintenance work. Following the 
commissioning, the manual must be made available to the operator. In your own interest, please observe the safety notices 
contained in this manual. 

 

Always handle chemicals with special care! 
Please contact your chemicals supplier for information about the safe handling of chemicals. 

 

 

WARNING! 
There is a risk of chemical burns and poisoning! 

 

Observe the relevant regulations when handling chemicals! 

 

-

 

Never mix different chemicals with each other.  

-

 

Only use chemicals that have been approved for the treatment of swimming pool water 

-

 

Wear suitable protective clothing when conducting maintenance work. 

 

Further information about the chemicals used is available from your chemicals supplier.
