Warning

Prior to installation, read these installation and 
operating instructions. Installation and operation 
must comply with local regulations and accepted 
codes of good practice.

Warning

If these safety instructions are not observed, 
it may result in personal injury.

Caution

If these safety instructions are not observed, 
it may result in malfunction or damage to the 
equipment.

Note

Notes or instructions that make the job easier 
and ensure safe operation.

Warning

When working with chemicals, the accident 
prevention regulations applicable at the 
installation site must be applied.

Observe the chemical manufacturer's safety data 
sheets when handling chemicals.

Warning

When working on the product, or connections 
and lines, always wear protective clothing (e.g. 
safety goggles and gloves).

The system must be unpressurised.

Only operate the system if all lines are connected 
correctly.

Warning

The chemical resistance of the parts that come 
into contact with the dosing medium depends on 
the medium, media temperature and operating 
pressure.

Ensure that all parts in contact with the medium 
are resistant to the medium under operating 
conditions.

Warning

Improper use, foreseeable misuse or 
misapplication can lead to personal injury and 
damage to the equipment and is therefore not 
permitted.
